Lunar Session - Total Lunar Eclipse - March 14, 2025

The eclipse postings on RASC discussion lists to date have been of images - both still and time-lapse. They have been phenomenal! However, on March 14, 2025, I chose 10x42 IS binoculars, a pre-printed map of the Moon and my SQM* as my observing tools of choice.

We were in our backyard where we had full view of the orb during our observing session 1am-4am. With battery operated gloves and socks and sandwiched between two sleeping bags on our park bench, we enjoyed the show the Solar System offered. 

I drew the lines as the Moon's surface was darkened by the Earth’s shadow up until 3:30am. However, in totality at 4 am, there was still what we referred to as a ‘polar cap’ on the N-NE limb. We did not observe past 4am to determine the timing of the re-illumination of the lunar surface.

From my rough notes:
  • 3:03am: SW limb showing hints of pink visually and in binoculars 
  • 3:30am: ‘polar cap’ still looked to be illuminated on its limb but no features could be discerned in binoculars.
  • 3:38am: ‘polar cap’ now turned pinkish but not as bright.
I also measured the darkening of the skies as the Moon was eclipsed. Here is the summary of my readings.

Sometime between 3:30am and 3:50am we noticed that stars were visible in Jerry’s telescope and now my binoculars.

In looking up, I saw several stars and quickly confirmed I had correctly identified the stars of Leo’s tail NW of the Moon. In binoculars, I could easily see 4 stars in a slight curve within the 6.5° FOV - p4 Leo, 58 Leo, c Leo, and x Leo. Gienah Corvi (𝜸 Corvus) was to the SW; I didn’t seek out the remaining stars of that constellation as I was so enthralled with Leo still being observable and so high in the sky.

Comet C/2023 A3 (Tsuchinshan-ATLAS) - October 18, 2024

Comet C/2023 A3 (Tsuchinshan-ATLAS)
Waning Gibbous Mon (96.7%)
Moonrise: 6:51 PM ADT

Location: Swiss Air Monument
Date: 2024-10-18
Time: 7:30 PM – 8:30 PM ADT
Equipment: Visual, 10x42 IS Binoculars, iPhone 13 Pro Max
Seeing: not recorded
Transparency: not recorded

We had made arrangements with Blair MacDonald to meet at the Swiss Air Monument on St. Margaret's Bay. It was to be a clear night but quite cold and breezy oceanside. Winter clothing was warranted. We left home around 5:45 PM ADT to allow us ample time to set up gear and to be ready for time-lapse and for visual observing when the comet made its first appearance. 

   2024-10-18 Earth's Shadow with Swiss Air Monument

Earth's Shadow at 6:22 PM was beautiful in the eastern horizon shortly after we arrived on site.

The blue-purple on the horizon is Earth's shadow (the shadow that Earth itself casts through its atmosphere and into outer space toward the antisolar point. The pink above it is the Belt of Venus (sunlight scattered by fine particulates that cause the rosy arch of the Belt to shine high in the atmosphere and lasts for a while after sunset)

   

The three of us set up cameras and iPhones along the granite crest adjacent to the Monument upon our arrival. At 7:30 PM, approximately 1 hour after sunset, the Comet was clearly visible half way between λ Ophiuchi and ω Serpentis in Serpens Caput. Its tail followed upwards to rise between  λ Ophiuchi and κ Ophiuchi.

A family arrived that normally would have one of the children choose a movie to watch on Friday evening. On this evening, the child didn't choose a movie - they chose instead to come view the Comet with binoculars. We were able to explain the constellations in which the comet was travelling through.

Throughout the evening, I had my iPhone on a tripod to better control the image for photos. I wanted the images to confirm the star field I was sketching at 8:00 PM ADT. As exciting as seeing the comet was, it was equally exciting to have a group who did not know the night sky but wanted to see this astronomical event. The cool temperatures with the very chilly wind had us ending the session one hour after first seeing the comet. A successful session nonetheless.

General Session - October 10-11, 2024 (Aurora Borealis)

Aurora Borealis
1st Quarter Moon
Located, but not observed through the Aurora:
Boötes, Cassiopeia, Big Dipper, Little Dipper, Venus

Observation #1:
Location: Stargaze Nova Scotia, near McGrath's Cove Road, Halifax

Date: 2024-10-10
Time: 6:55 PM – 10:10 PM ADT
Equipment: Visual, iPhone 13 Pro Max
Seeing: not recorded
Transparency: not recorded

We drove to Stargaze Nova Scotia and were joined by its proprietor, John Read, as well as Blair MacDonald and 3 other of John's friends; others arrived throughout the evening. He took us along a path that one of his students had made over the summer to a high point overlooking a small lake. En route there were several 360° views of the horizon. Absolutely incredible.

The 'show' began a little after 7:30 PM with faint glimpses of colour to the naked eye; pictures confirmed it had started. A bull frog's croak seems to confirm that was so.

At 8:14 PM, I texted our daughters: "If you aren’t outside, looking up, do so right now. The Aurora are absolutely incredible!!!" We had to laugh at the response: "Oak Ridge Memorial Gardens (graveyard) was the place to be! We were just approaching it as Mom texted to look up. Worked out perfect coming home from a school event! It was the boys first time seeing the northern lights, and my first time being in a packed graveyard at night lol"

Over the next two hours at Stargaze Nova Scotia, we had an indescribable show of the Aurora! The aurora's corona was indescribably beautiful with its full range of colour visible to the eye - red, yellow, greens, blues and violet. Not only did the 4 of us at our location on site exclaim "oh, wow!" at various times when the aurora was at its fullest, but you could also hear John and Blair closer to the ARO and some children at a nearby cottage. 

The wind on the ridge was cool for a period of time but once the wind died down, it was comfortable enough to go without winter mitts. Jerry had 2 cameras taking time-lapse and I had my iPhone in a tripod holder (sometimes) or handheld (most times). It was difficult determining in which direction to look! West? East? North? Straight up? Even the Halifax light dome did not diminish the aurora's intensity. 

By the light of the silvery 1st Quarter Moon

One view that I just loved was looking towards the Moon to see the clouds illuminated so brightly and the aurora's edge seemingly attempting to catch up to it.

The image of the Moon was blown because it was so bright compared to all else in the sky.

Many other images were captured but do not do justice to what we actually saw.

Jerry produced a video of his time-lapse captures via camera and his iPhone 15 Pro Max - https://vimeo.com/1018703128.

We knew there was to be a second show of the aurora and we were far from disappointed when we reached home. Again a 180° view of the aurora but this time it did not extend over our heads as it had at Stargaze Nova Scotia earlier in the evening. So disappointing when it faded to almost nothing just after midnight.

The two photos below were taken at 11:04 PM ADT.

After a cloudy night we woke to sunshine and calm waters. A Fox Sparrow greeted us, even came within 6' and stared at me before deciding it wasn't safe to get closer so dashed away. The squirrels carried on as per usual with their shenanigans.

Following a scrambled egg with bacon, toast, coffee, and strawberry-banana-with-yoghurt breakfast, we decided to go for a paddle on the calm Kejimkujik Lake waters. We left our site and headed south towards a small unnamed island adjacent to The Sisters before heading back north between Big Muise and Little Muise Island. It was here that I named a large glacial erratic as the Space Shuttle because it reminded me of the shuttle's nosecone. While paddling, we reminisced about the October 4-6, 2021 Star Party we enjoyed with the Chapmans - similar calm waters and such clear skies.

Before submersing long enough to get wet
Following our corned beef on rye sandwich lunch, we moved on to our next adventure - a swim in the not-so-warm Kejimkujik Lake! Did I mention it was COLD!! Too cold for me to go for a swim (which isn't like me not to go for a swim). Thankfully, after quickly getting wet, it was back to the beach to let our bodies warm up in the afternoon Sun. Even had some time for reading before dinner. While Jerry walked to the north point to determine the best location to view the sunset, I witnessed a Bald Eagle fly in a circle twice in front of me before diving to catch a fish. Wow. First time I have ever seen an Eagle here.

At 6:40 PM, we walked north on the stone beach to the island's point so that we could witness the sunset. Hoped to also see Mercury and the waxing Crescent Moon as the Sun set but clouds on the horizon prevented seeing either one. I took photos and Jerry took video. Beautiful colours. As the skies darkened, Arcturus became visible. 

Loons provided a brief serenade to our south at 6:48 PM. Shortly after, we headed back to the campsite for an evening under the stars. There was a threat of smoke that would affect the transparency later in the evening. Fingers crossed it wouldn't be significant.

Jerry setting up his camera for sunset time-lapse

Towards the north, the three stars of the Dipper handle (Alioth, Mizar and its less bright partner Alcor), Alkaid) were visible above the tree line. Above our heads, the bright stars forming the asterism DAVe (Deneb, Altair, Vega) shone brightly. 

The 8 stars in the Teapot asterism were visible, including Kaus Media that wasn't seen last evening.

And there was Corona Australis (CrA) south of it! With pencil and sketch pad, I began sketching the constellation's arc - ε CrA and two adjacent stars, γ CrA, α CrA (Alphekka Meridiana), β CrA, δ CrA and ζ CrA. I could also see V686 CrA and λ CrA that, according to the charts, were not part of the Corona. 

Three stars in the southern portion of the constellation were clouded over - θ CrA that was part of the Corona along with those that were not (V681, η1, and η2). One goal of the trip reached!

 
Corona Borealis (south of the Teapot)

While the Teapot was above the horizon, I followed the line out from Ascella to Kaus Australis to look for M7 (Ptolemy's Cluster) and the smaller M6 (Butterfly Cluster). It took a while to locate them because of the slight haze but they were both found. M7 is still one of my favourite open clusters. So beautiful. 

Red Antares was located in Scorpius, as were Al Niyat (τ Scorpii), Al Niyat (σ Scorpii), Dschubba and Graffias.

It wasn't dark enough yet to see M4 even though Scorpius was just high enough above the trees to locate it; the remainder of the claws and the body were hidden in the trees. By the time it was dark enough, M4 was below the tree line.

Scorpius above Minard Island

I knew I could not observe the structure of M10 and M12 with binoculars but decided to sketch the starfield around them. What was interesting was the rectangle of stars seen northeast of M12 that I could not identify in SkySafariPro; they were so evident in the binoculars but not so in the app. But there was a group of four stars to the west that formed an elongated "T" that I could identify. Two stars between them - HD152210 and HR 6248 - were angled.

Starfield around M10 and M12 in Ophiuchus

I stared at Ophiuchus for a bit afterwards at the area above Cebalrai (β Oph). The cluster above the eastern shoulder had caught my eye earlier in the evening. First, I visually confirmed it was Ophiuchus and that the line of stars angled towards the east were those of Serpens Cauda. 

After a few attempts to find Cebalrai with my binoculars, I found it then saw several stars above it; no nebulosity was seen around them. There appeared to be three rows of stars - one pair seemingly parallel to each other and the third angled away from it.  HR6670 was almost as bright as Cebalrai! SkySafariPro identified the cluster as IC 4665 / Collinder 349 / Melotte 179. I found it interesting that the cluster was so clearly visible between Ophiuchus and Serpens Cauda.

Once home and confirming the ID of stars in its centre, I came to realize that what I was looking at was the now defunct constellation Taurus Poniatovii (Poniatowki's Bull). Dave Chapman had pointed me to this "little bull" in 2022 and here I am "rediscovering" it two years later! So exciting!

Cosmicpursuits.com described it: "[The inner stars] form the pattern of the word “HI”, like a big friendly cosmic greeting."

 
IC 4665 / Collinder 349 / Melotte 179

Looking westward, I followed the zigzag line of stars forming Serpens Caput (the head of the snake). Looking further north almost to the zenith was the Keystone of Hercules. I used binoculars to find M13 and was it ever bright! When Jerry found it, he thought it was another star!

At one point, Jerry was trying to locate and capture the Dark Horse Nebula. It was lower in the sky at that point and not as dark as we usually see it. I informed him it was comprised of many elements - the Pipe Nebula (bowl of the pipe forming the horse's hip and the stem serving as a rear leg), plus many Barnard's Nebulae (Barnard 63 forming its bent front leg with the head and torso formed by 67a, 72, 75, 261, 262, 266, 269 and 396.) Who knew we were looking at numerous dark nebulae all these years?

Saturn in Aquarius

While examining the Milky Way, I recognized the Scutum Star Cloud, so easily located M11 / Wild Duck Cluster / NGC 6705 in my binoculars. I showed Jerry where to look and to imagine a golf club head adjacent to a fuzzy golf ball. 

We then began looking eastward once more. Fomalhaut (α Pisces Austrini) had just come past the trees of the south shore of our island. The other stars in Pisces Austrinus were also visible above the horizon but I did not specifically identify them. 

Above Pisces Austrinus was a very bright entity - Saturn. In binoculars, it was an ellipsis only; the magnification of 10x42 Binoculars didn't allow for much else. SkySafariPro showed the planet was in Aquarius. This prompted me to identify and sketch the stars surrounding the planet.

It was at this point that I looked for the asterism DAVe again. Visually going up 1/3 of the way between Altair and Vega, I stared at a point and when I put up my binoculars there was the Coathanger / Brocchi's Cluster / Cr 399. It was now 11:30 PM and the haziness/murk at the horizon was increasing as were the threat of clouds in the west. Bedtime.

We woke up at 7:30 AM to welcome another beautiful sunny day with mirror-like waters. After breakfast, we packed up and headed once more out onto the Lake. It was such a beautiful day that we decided to do some leisurely touring. We paddled past the group campsite on Ritchie Island to head south towards the eastern isthmus of Little Muise Island to determine if there was a suitable place that faced south for astronomy equipment, then turned to head north again. At the north point of Ritchie Island, we were curious about a small structure we saw; we paddled to it to discover it was an inuksuk. This was not appropriate for this Park (it was reported before we left the Park). Headed north to the Mersey River to unload the canoe, loaded the car, and headed home.

We left home 30 minutes later than planned. All was well despite an accident on Hwy 103 that detoured us onto Exit 7 through Chester then back to the 103 via Exit 9. We checked in at the Visitor Centre and when heading down to Jake's Landing I remembered we did not pack the eyepieces. Consequently, we left the telescope gear and the Messier Catalogue forms I had brought in the car. What a letdown! A binocular observing trip it will be - back to basic astronomy and getting visually reacquainted with the dark skies.

The upside? It was the amazing sunny day, only a few clouds scattered across the immense blue sky, and no wind. The only waves were those created by our canoe and paddles. We had experienced this only once before - 2 years ago with the Chapmans. It also meant some beach time, leisurely reading and just enjoying nature.

A couple from the UK was having lunch on the beach when we arrived around 1:30 PM. Had a nice chat with them while we enjoyed our lunch. Set up camp and enjoyed some time on the waterfront. I napped in the warm tent before dinner.

Heading out of the Mersey River into Lake Kejimkujik 

Wildlife in the area kept us entertained throughout the day. 

  • Six Mergansers entered our island's bay in mid-afternoon, swam past us then turned to head to the opposite side of Minard Island.
  • Four Common Loons swam past; the lead Loon repeated a single "peep" at regular intervals; they did not, however, honour us with their long mournful calls then nor during the night.
  • At least two Fox Sparrows zoomed across the forest floor looking for edibles. Only once did I see one fly up to a tree branch.
  • Three Red Squirrels! Perhaps youngsters. We laughed as they raced across our site. One very cautiously approached us in spurts to realize within 6' of us it wasn't a good idea to do so. Hilarious watching two or all three chase each other all over the campsite, and then call out seemingly angrily at each there from different vantage points. They did not make for a totally quiet campsite. 

It was an evening of intermittent cloud. We knew that would happen so determined this was to be an evening sitting by the fire. Dinner was planned accordingly - hotdogs roasted on the fire! So good! A glass of wine to enjoy with our meal.

Out on the beach afterwards, we did enjoy clear skies a couple of times. I was very tired, a little frustrated at my forgetfulness (having left the eyepieces at home) and generally was not enthusiastic about being under the stars - despite the beauty above us. I did not note times nor did I sketch.

One of my astronomy goals for the trip (besides the Messier objects) was to locate and sketch the stars in Corona Australis. Unfortunately, the clouds only allowed me to see a few stars in its curve and the horizon was a bit murky. Even the dimmer Kaus Media in the Teapot could not be seen, despite all the others being not so bright but perfectly identifiable. What I did find was M22 using binoculars; Kaus Borealis, the adjacent 3-star Y-shape and M22 itself easily filled my binocular FOV.

Capricornus was high, front and centre in the southern skies. With binoculars, could easily find and identify Deneb Alegiedi on its upper east side. The visual double of Prima Giedi (α1 Capricorni) and the brighter Secondi Giedi (α2 Capricorni) was found in the west side with binoculars. Other stars forming what I refer to as the clown's smile were readily identified as well.

Three stars (Deneb in Cygnus, Altair in Aquila and Vega in Lyra) comprising the asterism DAVe were visible earlier in the evening; consequently, it was easier later in the evening to find the 5 stars of Delphinus and the 4 stars of Sagitta. Jerry found the Coathanger asterism so I followed suit. 

Ophiuchus was high above Minard Island, its arced base very evident. M9 had alluded me at SCO in September so I attempted to find it here with Sabik (η Ophiuchi) in Ophiuchus and ξ Serpentis in Serpens Cauda easily seen. I think I found a small grey fuzzy when triangulating from these two stars with binoculars - but not certain.

By the time I turned to look northward, only the three/four Big Dipper stars were visible above our island's tree line. The double Mizar and Alcor were readily found with binoculars.

Facing south again, a bright entity caught our eyes - Saturn. Could make out a slight elliptical shape in the binoculars. In SkySafariPro, I noted that it was in Aquarius and confirmed the shape of the part of the constellation in which it was located but did not take time to note the star names. Nearby was Fomalhaut and I recognized its fellow stars comprising Pisces Austrinus. Above and a bit more east above the tree line came the tail stars of Cetus; our island's trees hid Mira and the constellation's structure above it.

Tiredness had set in so after a brief period in front of the fire with Jerry, I called it a night at 10:30 PM. He stayed up a bit later to monitor his time lapse session.

Learning to slew this new-to-me telescope to the object, and thankfully Ophiuchus remained high in the sky for this session. I have viewed M10 numerous times with 10x42 IS binoculars so knew generally where to look along the line (1/3 of the way up) from Sabik to κ Oph. 

It was a very faint roundish object. I could not see any individual or bright grouping of stars within the cluster.

I wanted to view this cluster in Ophiuchus with larger magnification and did so this evening. I could actually make out some of the stars in its nebulosity with eh 25mm eyepiece (100x magnification). It had a bright core but was seemingly diffuse. There was one bright star north of it then several on the opposite side of the object.

We had an early arrival at the Observatory to set up and for Jerry to take a video of one of the Centre's scopes. Michael joined us around 8 PM. It was at 8:30 that we heard the owl hoot west of us. The peeping frog started up shortly thereafter in the south and serenaded us throughout the observing session with his owl friend interjecting occasionally. Heard one coyote howl north of us.

Because of what was on the southern horizon, I decided to focus on Messier objects around the Teapot and Capricornus. I had hoped to sketch the stars of Corona Austrinus but by the time we had set up it had partially disappeared in the horizon. First success? M75.

M75 / NGC 6864
Time: 8:48 PM ADT
M75 had a relatively bright core and was partially resolved at its edges; I could not discern any individual stars of the object. Its rim did appear to be quite wide. Interestingly, the stars south of the object were easily detected but couldn't see anything north of it. For more details, refer to Messier Catalogue - M075 / NGC 6864.

M73 / NGC 6994 Cr 426
Time: 9:12 PM ADT
I had to wonder why Messier included this 4-star asterism. It appears that he saw a nebulosity around these stars that no has seen; the explanation given was the transparency and/or seeing may not have been perfect and therefore gave the illusion it was nebulous. I did not notice a colour difference but did notice a difference on their brightness. For more details, refer to Messier Catalogue - M073 / NGC 6994 / Cr 426.

M69
Time: 9:28 PM ADT
I used Kaus Australis (star in the base of the Teapot asterism) from which to slew and find this object. There was enough time between cloudy sessions to sketch the object and the very bright star adjacent to it. For more details, refer to Messier Catalogue - M069 / NGC 6637 - September 29, 2024.

M10 / NGC 6254 - Repeated
Time: 9:54 PM ADT
M10 was much larger in this scope and I could see more stars and had a better view of its nebulosity. It had a brighter core but its seemed diffuse rather than really dense. For more details, refer to Messier Catalogue - M010 (NGC 6405) - July 2022 & September 2024.

M12
Time: 10:03 PM ADT
I wanted to find this with a larger magnification just as I had with M10. However, could not do so due to clouds intervening. 

M32 / NGC 221, M110
Time: 10:03 PM ADT
These three were not in one FOV, but 2 of 3 isn't bad. M32 appeared as a bright str in the outer nebulosity of M31, the Andromeda Galaxy. Had to slew a bit to find M110 which appeared a smudge below M31. For more details re M32, refer to Messier Catalogue - M032 / NGC 221 - September 29, 2024. For more details re M110, refer to Messier Catalogue - M110 / NGC 205 - September 29, 2024.

M33 / Triangulum Galaxy
Time: 10:03 PM ADT
All evening when looking at this section of sky, the constellation Triangulum was easily identified. But, as the sky gods would have it when going to observe the galaxy nearby, they sent clouds in to obscure the whole area.

Packed up and left SCO at 11:00 PM. The clouds dictated a very early end to the evening.

There were intermittent periods of cloud cover so had to be patient for this area of sky to clear.

M75 is located west of Capricornus. It had a relatively bight core with a wide diffuse border, but I could not discern any individual stars of the object. 

There were stars south of it that were easily detected but I could not 'see' any stars north of it. Upon finishing this sketch, the clouds arrived.

This session began earlier in the evening but clouds broke the observing session into segments. In this case, cloud interference meant I could not sketch the star field.

I found these four stars above θ Capricornus and nearer to ν Aquarii; it was west of M72 (that I could not find during this session). I was a little surprised they were included in the Messier list. With so few stars visible, it did not appear as one of Messier's 'traditional' clusters. There was no nebulosity around them and no other discernible stars. I did not have time to notice a colour difference before the clouds came in but did not there was a slight difference in their magnitude.

Constellation:  Aquarius
Type: Open Cluster / Asterism
Apparent Magnitude: 8.9
Mean Distance: 2.0 kly

Some background on M73:

M73 was discovered by Charles Messier on the night of October 4/5, 1780. In his notes he wrote: “Cluster of three or four small stars, which resembles a nebula at first sight, containing a little nebulosity: this cluster is situated on the same parallel as the preceding nebula: its position was determined from the same star Nu Aquarii.”

Although many shake their heads at Messier’s log of four stars, other historical astronomers continue to follow suit and observe it. On September 28, 1783, Sir William Herschel notes: “Consists of a few stars arranged in triangular form. No nebulosity among them.” Later, his son John would catalog this same “nothing” group as GC 4617, noting that they were a “Cluster ??; extremely poor; very little compressed; no nebulosity.” If that were not enough, even Emil Dreyer would catalog them as NGC 6994!

In 2000-2002 several astronomers conducted an analysis of the colours and luminosity of stars in and around M73, and concluded it was an open cluster as seen in a Hertsprung-Russell Diagram. The controversy was resolved in 2002, when M. Odenkirchen and C. Soubiran published an analysis of the high resolution spectra of the six brightest stars within 6 ′ of the centre point. They demonstrated that the distances from the Earth to the six stars were very different from each other, and the stars were moving in different directions. Therefore, they concluded that the stars were only an asterism.

In my observation, I noted a slight difference in the stars' magnitudes. Online, I learned they had apparent magnitudes of 10.48, 11.32, 11.90 and 11.94 (according to GAIA EDR3).

Having found the Andromeda Galaxy numerous times in the past - visually, binocular and telescope - it was not a challenge to find it again. I had the scope go to Mirach then slewed 'upwards' to M31. I found what I thought was a bright star in an outer edge that was quite nebulous. I had two others at SCO confirm that what I was seeing was indeed M32.

Compared to the Andromeda Galaxy, this satellite galaxy of Andromeda was minuscule in size but it was quite bright compared to the nebulosity surrounding it. No other details within th galaxy other than its brightness could be discerned.

Discovered this when observing M31 and M32. Initially I was looking for a mini-M31 but then realized the smudge below it in my FOV was in fact M110.

It was fairly bright for a smudge, and was quite small and at a different angle when compared to M31. I believe it was an oval shape (or maybe it was my eye wanting to believe it).

Jerry helped me realign the scope, hoping it would track better. It did.

Skies were perfectly clear when we arrived, clouded for a brief period, and then located M69 when it cleared.

I used Kaus Australis (star in the base of the Teapot asterism) from which to slew and find this object. The cluster had a bright core and was just slightly less bright away from the core. It was not very big. There was enough time to sketch this small cluster and its nearest bright star (HD 170500) before clouds once more intervened and prevented any further sketching.

It was a great night at SCO. No wind was evidenced in the mirror-like water in the south and east and it was cloudless throughout the session. When we first arrived, an owl was hooting quite close by. FLIES! And we didn't bring repellent so it was an interesting evening to determine who won out - us or the flies. At 10:05 a flock of geese could be heard to the south but they didn't surprise us by landing in the southbound as they did on September 14th.

This was to be a Messier night but I had challenges with alignment go the scope and generally just finding these faint fuzzies.

Following failed attempts to find M110 near the Andromeda Galaxy and M9 near the star Sabik in Ophiuchus/Serpens Cauda, I found M30 and this was followed by finding a second Messier of the night - M72 north of ν Capricornus and not too far away from M73 (which I did not observe this evening).

M72 was faint and diffuse but I could make out 2 stars in the cluster. It was diffuse throughout the cluster with no apparent dense core.

When we first arrived, an owl was hooting quite close by. FLIES! And we didn't bring repellent so it was an interesting evening to determine who won out - us or the flies. At 10:05 a flock of geese could be heard to the south but they didn't surprise us by landing in the southbound as they did on the 14th.

Jerry assisted me in getting the scope set up and aligned but unfortunately it hadn't been polar aligned so it did create challenges throughout the observing session. Bob and Blair joined us shortly after our arrival.

M31, M32
Time: 9:00 PM ADT
Eyepiece: 30mm
My first objects were in Andromeda which was quite high and visible from the centre observing pad. However, I wasn't sure if what I was seeing was in fact M32. Blair found it in his Dobsonian with a 20mm eyepiece; M31, M32, and M110 were all in the eyepiece - which confirmed that what I thought was a star in M31 was actually M32. I determined I would let this one pass for now.

M9
Time: 9:18 PM ADT
I made a few attempts at finding this object. I sent the scope to Sabik then tried several times to slew to find it. Unfortunately, it went into the trees before I could identify it.

M30
Time: 9:48 PM ADT
Success! But only after a couple of failed attempts t locate it. M30 was located east of ζ Capricornus, almost due south from Deneb Algiedi. It had a dense core with at least 3 lines of stars emanating outward from its bright and dense core. For more details refer to Messier Catalogue - M030 / NGC 7099 / Jellyfish Cluster.

M72, M73
Time: 10:31 - 10:46 PM ADT
Given Capricornus was still high in the sky, I attempted to find this pair of objects north of θ Capricornus.
M72 was found after a couple of attempts. It was fairly faint and diffuse but I could make out 2 stars in the cluster. For more details refer to Messier Catalogue - M072 / NGC 6981. M73 was a bust. For some reason I could not find it east of M72.

Jupiter
Time: 12:02 AM ADT
Although the planet was very visible in Taurus in the eastern skies, I used the goto feature to observe it. 

The planet and its 4 Galilean moons were quote clear. Could not discern the Great Red Spot (GRS) at this magnification but could see the striping that almost aligned with the line of moons

     

Uranus
Time: 12:09 AM ADT
I knew this planet was close to the Pleaides, so used the go-to feature to slew to it. A glorious little blue dot was centred in the FOV. 

Time: 12:15 AM ADT
I was chilled at this point and my hands were beyond cold so had a hot chocolate and snacks in the Warm Room and relaxed a bit before we packed equipment and headed home.

Time: 1:20 AM ADT
Orion was in front of us on the drive home, lying on his side and about 10°-15° above the horizon. His red Betelgeuse was easily identified.

Time 2:10 AM ADT
The skies were still beautifully clear when we arrived home. When we stepped out fo the car and looked at the skies across the street, a red org was above the tree line - Mars - and further up was Capella bright as could be. A wonderful evening had come to an end. Light out at 2:38 AM.

The star field had a few bright stars of note - one at 2 o'clock and 2 others in the east.

IWLOP #L9 - Ulugh Bay and Aston

Craters near the western edge of the Moon, just beyond the edge of Oceanus Procellarum.

Origin: impact     Size: 54 km, 43 km   Rukl: 8     Type: Craters

Objects: Ulugh Beigh, Astoni
Others Identified: Aristarchus, Briggs, Eddington, Herodotus, Lichtenberg, Lavoisier, Lavoisier A, Russell, Seleucus, Struve, von Braun

Date: September 18, 2024
Time: 1:10 AM - 1:45 AM ADT
Equipment: Telescope
Eyepiece: Antares Plössl 15mm, Explore Scientific 4.7mm with 82° FOV
Magnification: x167

These craters weren't the easiest to find. The RASC Observer's Calendar depicted the favourable libration and to my surprise it meant L9 could be searched for. 

Using my S&T Field Map of the Moon, I determined that if I went to Aristarchus & Herodotus (very easy craters to find) and looked to their west on Oceanus Procellarum (OP) to the crater Lichtenberg, the dark-floored Ulugh Bay should be west of it and just a bit inshore in the mountainous area. Using the Explore Scientific 12mm eyepiece, it took at least 5 minutes to visually navigate within the FOV to find them. 

But I wanted a closer look so with Ulugh Beigh/Aston centred in the FOV, I changed the eyepiece to the Explore Scientific 4.7mm. Completely lost them!! Total white-out! For the next 15 minutes or more, neither Jerry or I could focus it to see any crater let alone the target. Back to the 12mm it was and after a few minutes had it back on target and in focus. 

I recognized Struve, Briggs, Eddington and Russell. Other craters (new to me) were noted as well on the shoreline and in the west border of OP - Lavoisier, Lavoisier A, Seleucus (with a white halo), and von Braun (quite white and caught your eye). Lichtenberg in the OP was interesting to note because it appeared to have a small ejecta field to its northwest.

General Session - September 17/18, 2024 (Partial Lunar Eclipse)

Partial Lunar Eclipse
Constellation: Aquarius
Stars: Albireo (ß1 & ß2) 
Planets:
Saturn + Titan & Rhea
Did not Find: NGC 6802
IWLOP: #21 Sinus Concordiae, #57 Linné, L9 Ulugh Leigh & Aston

It's not often you get to see a partial lunar eclipse and have the sky conditions allow it to be viewed. We had 3 methods to observe it at its various stages - visual, binocular, telescope - and Jerry had his camera set up to take photos to produce a time-lapse video. During the wait between changes on the lunar surface, we looked up to see what we could see. 

Sketching at the Scope
Sketching at the 10" Meade
Location: Home
Date: 2024-17/18, 2024
Time: 9:00 PM - 1:50 AM
Equipment: Visual, 10x42 IS Binoculars, 10" Meade SCT, 
Eyepieces: 10mm-30mm Scientific American Zoom eyepiece, 12mm, 40mm

Temperature: 22° C - 16° C
Seeing: Fair (4)
Transparency: Fair (4)

9:00 PM: The Moon was just above our neighbour's roofline but not high enough yet to be seen where our scope was located. Jerry began to polar align the 10" Meade SCT and then realized he also had to align the finder scope with the scope. This took some time to accomplish.

9:10 PM: I noticed a line/curve of smoke (or very high cirrus clouds) extending from Arcturus to a little beyond Deneb. Hopefully the forecasted smoke wouldn't have a great effect on our view. So, while waiting for the Moon to appear in our FOV....

Albireo
Time: 9:17 PM ADT
Equipment: Telescope
S&T Chart Reference: 62

Eyepiece: Tele Vue 12mm (90° FOV)
Magnification: x208
After completing the polar alignment, we used the go-to to find Albireo. We weren't disappointed. The yellow-gold β Cygni A was the larger of the two and the blue-green β Cygni B was at 10 o'clock to A. I sketched the star field in the FOV but could not identify all the stars in.

NGC 6802 / Coathanger Cluster
Time: 9:30 PM ADT
S&T Chart Reference: 64, 65
Equipment: Telescope
Eyepiece: Tele Vue 12 mm (90° FOV)
Magnification: x208
I discovered this open cluster butting against the Coathanger at the St. Croix Observatory (with Chris Young and his sister Cathy). My Evostar 80ED did not have "CR" as a choice so we tried to find an NGC nearby - et voila! Unfortunately, the seeing this evening did not allow us to find it. The Coathanger wasn't visible by any of our 3 observing methods. Got to love smoke/clouds!

IWLOP #021: Sinus Concordiae
Time: 10:06 PM ADT
Equipment: Telescope
Eyepiece: Tele Vue 12 mm (90° FOV)
Magnification: x208
although viewed several times it had never been 'officially' identified. The IWLOP suggested viewing this at or near the full moon, so this was the perfect night - Full Moon 'Supermoon' at 100% no less! For details, go to IWLOP #021 - Sinus Concordiae.

IWLOP #057: Linné
Time: 10:38 PM ADT
Equipment: Telescope
Eyepiece: Tele Vue 12 mm (90° FOV)
Magnification: x208
This second viewing of Linné was 1 hour before the full Supermoon. For details, go to IWLOP #057 - Linné.

Saturn (in Aquarius)

Time: 11:27 PM
Equipment: 10x42 IS Binoculars
I was looking to identify the bright object east of the Moon. Turns out it was Saturn in Aquarius. Sketched the star field in which it lay.

Time: 11:52 PM ADT, 1:48 AM ADT
Equipment: Telescope
Eyepiece: Celestron focal reducer/corrector - f6.3, Tele Vue 40mm Plössl eyepiece
Magnification: x39
This observation had Saturn tilted at 45°. Its rings were still being seen side-on so no distinction of separation from the planet nor of the Cassini divisions. Titan looked to be 'protected' under the rings and Rhea was seen above along the same plane as the rings. At 1:48 AM, no moons were seen, perhaps due to the cloud or smoke.

Time: 3:04 AM ADT
Equipment: 10x42 IS Binoculars
I woke, looked out the bedroom window, and used my binoculars to view Saturn that was now S-SW above our trees. Could only see the planet.

Partial Lunar Eclipse

Jerry and I both had an interest in this event - me from a visual observer's perspective, him from an astroimager time-lapse photographer, and both of us from an amateur astronomer perspective as this was our first observed partial lunar eclipse. 

I had my 10x42 image-stabilized binoculars at the ready and the 10" Meade SCT.

He took photos using his Nikon Z7 at 1/320 sec, f10 with a 400mm lens.

Two chairs and a table were placed between the scope and the camera facing south for front row seat observing. Hot chocolate in our thermos and a bag of chips at the ready.

We noticed a colour change in the eastern limb a little after 10 PM. Unfortunately, I didn't note the exact time in my log but Jerry captured the darkening beginning.

Equipment: Visual, 10x42 IS Binoculars, Telescope
Eyepiece: Celestron focal reducer/corrector - f6.3, Tele Vue 40mm Plössl eyepiece
Magnification: x39

The Moon would not "fit" in the scope's FOV. Jerry suggested adding the focal reducer which also provided a wider FOV and there it was - the full Moon in my FOV.

  • Visually: The Moon appeared to have a flattened top. The area above Mare Frigoris had darkened but was still visible.
  • Binoculars: Can make out Mare Frigoris but not the upper limb. Similar in darkness to the sky behind the Moon.
  • Telescope: Can see the land mass in a darkened area but cannot discern the numerous craters known to be in the north polar area.

Time: 11:27 PM ADT
Equipment: Visual
The area over northern Oceanus Procellarum, Sinus Roris, Mare Imbrium, and Sinus Iridum seemed darker than other areas of the Moon.

  • Visually: The Moon 'cap' was blackened. The polar region was gone with no colour difference between it and skies behind it. The northern hemisphere seems to be in partial shadow whereas the area around Tycho and Mare Crisium are still relatively bright. 
  • Binoculars: Can just barely make out the northern limb. Aristarchus still shone through at the edge of the darkness. Copernicus and Kepler were certainly subdued as well.
  • Telescope: Shows a darkened area to the southern shore of Mare Frigoris.

The Moon's dark 'cap' had tipped eastward. I jokingly suggested it gave the Moon a more sporty look. The umbra had shifted a bit from west to east; however, the northern hemisphere remained in the penumbra.

Time: 11:59 PM ADT
Equipment: Visual
The dark 'cap' appeared less black at the pole.

The dark 'cap' is now a bit lighter in colour. Western Mare Frigoris and northern Oceanus Procellarum were darkened but visible. Now lost in the Umbra were the eastern area of Mare Frigoris, Lacus Mortis and Lacus Temporis. The northern hemisphere in general remained in the penumbra but was darker in the east.

Time: not recorded
I watched shadows disappear from the lunar surface but did not note the time when evidence of the eclipse was last visible. Jerry fortunately had a photo of the penumbra on the northweastern limb showing the remainder of the Moon back to its luminous self. The last photo he took was at 12:56 AM ADT. Visually, it looked like the Moon was back to the 100% Supermoon.


IWLOP #L9: Ulugh Bay & Aston

Time: 1:10 AM - 1:45 AM ADT
Equipment: Telescope
Eyepiece: Antares Plössl 15mm
Magnification: x167
These craters weren't the easiest to find. The RASC Observer's Calendar depicted the favourable libration and to my surprise it meant L9 could possibly be found. Using my S&T Field Map of the Moon, I determined that if I went to Aristarchus and Herodotus (very easy craters to find) and looked to their west on Oceanus Procellarum (OP) to the crater Lichtenberg, the dark-floored Ulugh Bay was there. For more details of the challenges in finding these craters, refer to IWLOP #L9 - Ulugh Bay and Aston.

The evening began at 6 PM with the Annual SCO BBQ. It then turned into a spectacular evening “🎼 under the light, of the silvery Moon.” The wind died down early in the evening making it easier for a few mosquitoes to find us but once the temperature dropped a bit, they disappeared.

I believe we all had a grand time looking at the Moon 🌖, be it through the scopes set up or through our binoculars. I had my 10” Meade SCT with a 10-30mm SvBony eyepiece. Had a blast locating craters and other features along the terminator, and certainly in sharing them with other members “new” to lunar observing and showing them on the Sky&Telecope lunar map where the features were located.

Here are my favourite photos - north to south - taken with my iPhone 13 Pro attached to the eyepiece with my NexYZ 3-Axis Universal Smartphone Adapter. I had viewed all of them throughout the evening but then went back to capture a photo of each. No records were taken of these observations as the intent of the evening was to introduce members to the Moon and some of its special features.

The shores of Mare Frigoris above Sinus Iridium (photo taken at 11:04 PM)

The large crater with an internal crater is Herschel with Horrebow on its SW wall. Directly above it is Anaximander with Carpenter to the east. The large crater in the darker Mare floor is Harpalus. Below Harpalus are 2 craters (L to R) Bouguer and Foucault. To Herschel’s west, are two small unnamed craters, and then the crater South with Babbage above it (in the dark).

   

 

In Oceanus Procellarum - Aristarchus, Herodotus & Vallis Schröteri (Schröter’s Valley) on the Aristachus Plateau (photo taken at 11:07 PM)

On the right, are two craters - Aristarchus (the bright-rimmed one) and Herodotus. From the northern (left) rim, you can see a snake-like valley heading NW - Vallis Schröteri, the largest sinuous valley (rille) on the moon (~ 155km). The start of the rill has been termed the “Cobra’s Head” due to its resemblance to a snake. You will also see the remnants of another crater (Prinz) near Aristarchus, and to the left/above Prinz are two small craters Krieger (with a small crater on its wall) and Wollaston. On the far left is Marian.

   

 

West of Copernicus - Kepler & Encke with T. Mayer (11:09 PM)

Copernicus and its spectacular ejecta field were very easy to find but what I wanted to have a closer look at Kepler and Encke. Keplar (right of centre) certainly has a larger ejecta field than Encke and is deeper given the shadows on both, but both are much smaller than Copernicus. To the left of Kepler, is T. Mayer with its very flat floor, bright-ish, low-rimmed walls. On the upper right very close to the terminator is Marius and to its lower left is Marius A.

   

 

The Diamond Ring on Mare Nubium

South of Oceanus Procellarum is Mare Nubium. On its northern shore, you see the large crater Gassendi with its two central peaks and its broken southern rim. Because of being inundated by lava during the formation of the Mare, only the rim and central peaks remain above the surface. On its northern wall is the crater Gassendi A. Together, they give the impression of a diamond ring. To the right of Gassendi is a crater with a darker floor and shadows - Marsenius.

   

 

Tycho & Clavius in Southern Highlands

Tycho with its central peak is centred in this photo. I refer to this crater as ‘the flower” because to me Tycho is the flower’s centre with the smaller, shallower craters encircling it appear as petals. Below Tycho is Clavius - a beautiful crater with an arc of 4 craters (all varying ages, apparently) on its floor; the 5th in the arc on the crater wall is Rutherford. Across from Rutherford on the opposite wall is Porter. With a much higher magnification, you would see several small impacts made on this crater. The all narrow crater on the upper right is Schiller, appearing appears very elongated due to foreshortening.

Messier Catalogue - M015 / NGC 7078 / Great Pegasus Cluster - September

Location: St. Croix Observatory (SCO)
Date: 2024-09-05
Time: 12:34 AM ADT
S&T Chart Reference: 75
Instrument: SkyWatcher Evostar 80ED with star diagonal

Magnification: x20 - x60 
Transparency: Very Good (4)
Seeing: Good (3)
SQM: 21.04
Temperature: 13º C

It was a great night at SCO! No clouds. No wind, not even a breeze. Six souls ventured into the wilderness to take in the dark skies. There were the two observer/sketchers (me being one of them) whereas the others were imagers. Lots to see but my focus this evening was the Messier objects. 

M15 was not close or in the Square of Pegasus as anticipated. SkySafariPro redirected me eastward to Enif. By following the line from Bihar (θ Pegasi) to Enif (ε Pegasi), I was able to slew to the cluster with the 30mm. Once found and centred, I used the 10mm. M15 had a very bright centre and was quite compact. It became less dense further away from the core. There was a very bright star close to the cluster that I identified as HD204712.

There were three stars in the upper right quadrant in V-shape that initially I could not identify until I realized I was using the 30mm eyepiece. The upper two were faint (SAO107121 & HD204094 at mag 9.1) compared to the brighter star (SAO107133 at mag 8.9) below them.

General Session - September 4-5, 2024

It was a great night at SCO last evening! Six souls ventured into the wilderness to take in the dark skies - Jerry & me, Michael Gatto, Peter Hurley, Blair MacDonald, and Bob Russell. Michael and I were the two observer/sketchers whereas the others were imagers. Lots to see last evening. Blair was capturing two Barnard dark nebulae. Bob caught more photons for his images of the Trifid and Heart nebulae.  Jerry was working on the Bubble Nebula (NGC7635), centred the Chandelier Cluster (NGC 6723) with HD 176386 with HR 7170, the Trifid Nebula (NGC6514/M20), the Triangulum Galaxy (M33), and the Pinwheel Galaxy (NGC 5457/M101). I am not sure what Michael and Peter were observing.

Truly hoping clear weather returns several times during September/October to capture more views of our amazing Universe. Hope to see more members out there! There’s an “oh, wow!” moment for everyone in the sky, but there’s also the fun of gathering under the stars, planets, galaxies, nebulae,.... There were some challenges with alignment but once that was solved, had a great night of viewing.

My mission was to capture as many Messier objects as I could and to sketch each one. I had my Evostar 80ED with a SvBony 10mm-30mm zoom eyepiece. There were some challenges with alignment but once that was solved, had a great night of viewing.
Two more Messier objects observed, sketched, ticked off the list, making it 42 of the 110 now completed.
 
Messier 22 / NGC 6656 / Great Sagittarius Cluster
Time: 9:28 PM
S&T Chart Reference: 67, 69
Equipment: Telescope
Eyepieces: SvBony 30mm-10mm Zoom eyepiece
Magnification: x20 - x60
M22 is a cluster that's been located by binoculars too many times to count! As always, used Kaus Borealis as the start point for the search. The cluster didn't appear completely circular because of the brighter stars in the S-SW giving it a more oval/almond shape. For details, refer to Messier Catalogue - M022 / NGC 6656 / Great Sagittarius Cluster - September 4, 2024.
 
Messier 21 / NGC 6531 / Webb's Cross
Time: 9:28 PM
S&T Chart Reference: 67, 69
Equipment: Telescope
Eyepieces: SvBony 30mm-10mm Zoom eyepiece
Magnification: x20 - x60 
I knew this was near the Lagoon (M8/NGC 6523) and the Trifid (M20/ NGC 6514) nebulae so had my telescope go to the Trifid then slewed from the Trifid to M21. According to SkySafari Pro, the star configuration I was searching for looked like a small shopping cart with a circle of dimmer stars attached. I found what looked like a shopping cart but the circle of stars above it eluded me. Not successful this evening for M21.
 
Messier 15 / NGC 7078 / Great Pegasus Cluster
Time: 12:34 AM
S&T Chart Reference: 75
Equipment: Telescope
Eyepieces: SvBony 30mm-10mm Zoom eyepiece
Magnification: x20 - x60 
M15 was not close or in the Square of Pegasus as anticipated. SkySafariPro redirected me eastward to Enif. Once found and centred, I used the 10mm. M15 had a very bright centre and was quite compact. It became less dense further away from the core. There was a very bright star close to the cluster that I identified as HD204712. For details, refer to Messier Catalogue - M015 / NGC 7078 / Great Pegasus Cluster - September.

    
Albireo
Time: 12:43 AM
S&T Chart Reference: 62
Equipment: SkyWatcher 16" Dobsonian Telescope
Eyepieces: Nagler 22 mm
Magnification: x82
What did we all look at? Jerry fired up the 16” Dob around midnight (didn’t get a good alignment) and used a Nagler 22mm eyepiece for an incredible view of Albireo - so big and bright with their colours, sizes, and relative positions with the star field very clear. The larger of the two ß1 (ß Cygni A) was amber coloured and much larger than the blue-green ß2 (ß Cygni B). ß1 was at 2 o'clock to ß2. It's not known whether they are an optical or a binary double.
M45 / Pleiades / the Seven Sisters
Time: 12:50 AM
S&T Chart Reference: 15
Equipment: Telescope
Eyepieces: SvBony 30mm-10mm Zoom eyepiece
Magnification: x20 - x60 
I located and looked at the Pleaides through the scope and shared it with Jerry. Always a joy to see this open cluster, always so shiny and easily identifiable. The nebulosity was not noticed but the star pattern was evident.

Jupiter (in Taurus)
Time: 12:56 AM
Equipment: Telescope
Eyepieces: SvBony 30mm-10mm Zoom eyepiece
Magnification: x20 - x60
Jupiter and its 4 Galilean moons were viewed together as well; Io and Europa were close together at 11 o'clock to the view of the planet whereas Callisto (the dimmer of the two) and Ganymede were very close together but a fair distance away at 5 o'clock.
  

 

Saturn (in Aquarius)
Time: 1:20 AM
Equipment: Telescope
Eyepieces: SvBony 30mm-10mm Zoom eyepiece
Magnification: x20 - x60 
I offered a view of Saturn in my scope to everyone. So amazing to see it so bright with no separation of the rings from the planet nor the Cassini Division. The rings were equally as bright as the planet and appeared as only a thin line as we were viewing them side-on. Wow. There was a semi-circle of what I thought were stars, but one of them was Titan, one of Saturn's moons.

M22 is a cluster that's been located by binoculars too many times to count! As always, used Kaus Borealis as the start point for the search then found the Y-shaped 4-star configuration (HD170978, HD171056, HD171097, 24 Sgr). M22 was in the same FOV as the 'Y'. It is a seemingly uniform dense cluster with no discernible stars at this magnification. However, by staring at it for several seconds was able to see a bright star at 3 positions of a clock within the cluster - 3, 6 & 9 o'clock. The cluster didn't appear completely circular because of the brighter stars in the S-SW giving it a more oval/almond shape.

It was a great night at SCO! No clouds. No wind, perhaps a little breeze part way through the evening that kept the flies at bay. Because this was a Member's Observing Night at SCO, I did not keep a written record of the evening’s observations but made the list once I returned home. Therefore, no idea as to timing except for the view of Saturn as it was observed after most folk had left SCO, and for some reason I had recorded it.

Nine souls ventured into the wilderness this night to take in the dark skies:

  • Me! touring the sky with my Evostar 80ED refractor to look for whatever I was asked to find. I had no particular objectives in mind. 
  • Dave Chapman had the Centre’s 16” Dobsonian in service and gave instruction in how to use the telescope. He shared close-up views of some of summer's showpiece objects.
  • Michael Gatto with his 13” Dobsonian sketched some Herschel objects.
  • Tony McGrath had his 120mm refractor and was star hopping through the southern sky.
  • Jerry was fine tuning the HyperStar imaging setup which he has assembled over the last several months, converting the Centre's 8 inch Celestron SCT into a superfast f1.9 imaging setup. 
  • Guests:
        - Chris Young (RASC member) was accompanied by his sister Cathy who was visiting from New Mexico,
        - Stephen Payne (RASC member) had brought along Laurent Kreplak, the head of the Physics department at Dalhousie University.

Chris requested I show his sister the double star Albireo. Nothing like being under pressure with two observers waiting albeit patiently to see this star. Altair and Arcturus were used for 2-star alignment purposes; Cathy saw Arcturus that was just about to disappear in the western treeline. Eventually, with Jerry’s assistance, the Evostar and I became friends and Albireo was centred in the FOV. Cathy saw the two stars and quickly noted the differing colours – one a yellow-gold with the other a blue-green.

I became friends with Cathy and we joined forces to tease her brother. This was certainly true when attempting to find the Coathanger (Cr399) asterism. Problem: the Evostar does not a Collinder (Cr) designation as a search choice, so we asked Chris to look for NGC 6802 that I knew was located at the end of the "rail" of the Coathanger. He was having challenges finding it (connectivity issues) but I did in SkySafariPro. Because of the wider field of view, both the NGC and the asterism were visible in the same FOV for all to see.

Mizar-Alcor (in the Big Dipper), Cassiopeia
With the Big Dipper so high in the northern sky, I pointed to the handle and asked her what she saw when looking at the centre star in the handle. Like others our age, she saw one star – until I asked her to look through her binoculars. I explained about Mizar and Alcor, and how Mizar (a double star) could be seen in a telescope. The pointer stars of the bucket and how they pointed to Polaris were also explained.

I also noted Cassiopeia nearby. I told Cathy the story of how our youngest grandson at the age of 5 was shown the constellation at Blomidon Provincial Park. Because he couldn’t pronounce it, it became known as the “William” constellation (named after him).

Milky Way, Scorpius
Looking south from the observing pads, the Milky way was pointed out along with the two constellations that were on either side. Scorpius was to the west and many of its main stars could be seen, especially Antares. I noted the curve of stars and how the scorpion body curved southward. Also mentioned the numerous Messier objects in the area. Chris and I explained how the star clusters came to be identified by the French astronomer Charles Messier.

The Teapot (in Sagittarius)
I also pointed out the Teapot, the asterism in the constellation Sagittarius. There were several Messier objects around it as well but it was noted that steam (aka the Milky Way) came out of the teapot spout. This made it a little easier to find in the night skies.

Perseus, Alpha Persei Cluster/Melotte 20/Collinder 39, Capella (in Auriga)
Chris, Cathy and I relocated between the Warm Room and the Storage/Washroom to view the constellation Perseus and the Alpha Persei Cluster. Using binoculars, I looked at this, one of my favourite clusters, with my binoculars (cannot remember if they did or not). Such a gorgeous open cluster! There was a bight object below it that initially we thought could be a planet but it was Capella (the brightest star in Auriga).

Keystone of Hercules, M13 (Hercules Cluster)
This was above our heads but not at Zenith. Using the binoculars, I quickly located the Hercules Cluster Eta Herculis and Zeta Herculis. Confirmed it was still a small grey fuzzy.

Boötes, Ophiuchus, Aquila, Cygnus
(Visual Observation)
West of Hercules, we could still see Arcturus (“arc to Arcturus”); I was able to quickly note where the other stars of the constellation were located. South of Hercules, I identified the 3 stars in the “cap” of Ophiuchus. This constellation always amazes me because of the enormity of the skyscape that it covers. Now looking into the Milky Way, Altair and its two fainter stars (Tarazed and Alshain) could be seen. The constellation Cygnus was then seen above Aquila and its brightest star, Deneb, quickly identified.

Saturn (in Aquarius)
Time: 11:38- 11:50 PM
Equipment: Visual, binoculars, telescope
Eyepiece: SvBony 10-30mm

I found Saturn initially visually, then located it in binoculars in the SE sky. When I used the telescope, I was able to identify the moon Phoebe. Also cool was seeing the rings edge on – no sign of distance between the rings and planet nor of the Cassini Divisions. I showed this to Stephen, Laurent, Dave, Michael and Jerry. The others had already left.

M4, M22
At some point in the evening when there was some quiet time at my scope, I looked for these two Messiers. M4 was to be found close to Antares in Scorpius and M22 in Sagittarius near the Teapot‘s lid star (Kaus Borealis). Unfortunately, I had waited too late – both constellations were quite low on the horizon and the horizon was a bit murky to discern stars – with binoculars or the scope. Bah!

Jupiter, Mars, Aldebaran
Looking out my passenger window while leaving SCO, I noted three bright orbs – Aldebaran (the brightest star in Taurus), Jupiter above it, and the reddish Mars above it – all forming a shallow triangle in the sky. Oh, to have my scope up now but, alas, it was packed in the trunk behind me. Bah!

General Session - August 11, 2024 (Sunspots)

This was our last afternoon at Nova East. Clouds were occasionally covering the sun and we knew it was to cloud over completely soon so decided to observe the sunspots using the solar filter built specifically for my telescope.

Location: Nova East at Blomidon Provincial Park 
Date: 2024-08-11
Time: 4:31 PM ADT
Equipment: Evostar 80 ED
Eyepiece: SvBony 30mm-10 mm

Magnification: x60

The sunspots were numerous in the Sun's lower hemisphere. The line of them extended from about 7 o'clock on the Sun's surface to 2:30 o'clock on the eastern limb. The sketch was a bit hurried as the cloud cover was encroaching the viewing field.

R1: Goldschmidt: Goldschmidt's SE rim bordering with Barrow is quite high with an irregular surface, creating an interesting shadow on Goldschmidt's flat floor. A "valley" appeared on the wall Anaxagoras impacted, almost as if it were a double wall - the taller side created by the creation of Anaxagoras and the other of Goldschmidt's pushed in wall due to the impact. The floor was also just a shade darker near this wall. The crater had an irregular shape to its rim and was quite worn down in areas (especially in the south) where it appeared almost non-existent. Goldschmidt's floor appeared lower than that of Barrow and Anaxagoras. 

R2:  Anaxagoras: I'm sure that because of foreshortening, it appeared oval in shape. I also assumed the Moon was hit obliquely as the west wall appeared terraced and at a lesser slope (also very well illuminated) compared to the higher eastern side that impacted Goldschmidt. I could not determine if there was a central peak because of the deep shadow. 

C1: Valley Radial: Between Archytas and W. Bond was the valley radial to the Mare Imbrium impact. At first, I thought it was a shallow crater with a disintegrated southern wall but then in a couple moments of stable seeing saw the ridges parallel to the crater walls and the continuity of flow to Mare Frigoris. 

C2: Craters: There appeared to be a few small craters (saw shadows for 2) on the crater's southern floor. There was a sizeable crater in the west near Anaxagoras due to an impact on its floor or wall or a combination thereof. There were a couple of dark shadows on its southern rim that could be due to craters; not sure.

C3: Infilling: Smooth floor of this crater suggested infilling. Others also appeared to have this - Meton, W. Bond, the crater-like area between Barrow and W. Bond, and a couple of unnamed craters between W. Bond and C. Myers.


Note: 
Barrow's floor seemed to be darker through the middle than on the north and south sides.

Lunar Session - June 14, 2024

Objects: Anaxagoras, Archytas, Birmingham, Challis & Math, Goldschmidt, Meton, Protagoras, Scoresby, W. Bond
IWLOP Objects: IWLOP #76: Goldschmidt

Location: Home
Date: 2024-06-14
Time: 9:00 PM - 10:15 PM
Equipment: 10" Meade SCT
Eyepiece: Tele Vue Nagler 9mm Japan eyepiece

Magnification: x278
Temperature: 20° C
Seeing: Fair (4)
Transparency: Good (3)

My goal for this session was to finally see all of the objects contained in IWLOP #76 - Goldschmidt and especially Anaxagoras. I had tried a month ago but was unsuccessful. Tonight there as success. For details of this observation, refer to IWLOP #076 - Goldschmidt.

Having found what I was looking for and completed the required and challenges for #76, I decided that given it was such a beautiful night I would stay out and get reacquainted with lunar craters that I haven't seen in a while. It was also just past 1st Quarter. The moon was illuminated 57.7% at this point so there may even be hope for Rupes Recta (Straight Wall) if all goes well.

First up? Deslandres (Centre of photo) caught my eye. Its western rim was just on the terminator but you could see the features of its floor:

  • Hell: crater in the west; crater rim well lit but interior very much in the dark. A small crater (in the dark) to its SW and two even smaller unnamed ones between Hell and Lexell
  • Lexell: crater that impacted and affected the SE corner of Deslandres.; central peak and its N-NW rim is almost non-existent. 
  • Ball: forms a triangle with Lexell and Hell. Much of its rim is illuminated but the lower west rim and its floor are matching the darkness of the terminator. There is an unnamed crater in the N with its rim illuminated, and there is a rille-like feature in the NW.

Below Delsandres is what I refer to as a mess of craters that over time had numerous hits:

  • Orontius (right: largest one with a scalloped western rim)
  • Sassure immediately below it
  • Huggins impacted Orontius's SE rim
  • Nasireddin impacted Huggins eastern rim
  • Miller had a small section of its souther rim touch by Nasireddin; central peak and ridged wall very evident.

If you follow the three craters lining up SW-NE above Miller, you come to Walther with its slightly off-centre peak and 4 aligned craters near the peak. This crater did impact Deslandres on its eastern rime. There is also an unnamed crater just inside its western rim.

Above Walther is Regiomontanus with its now off-centre peak. Its southern rim is separated from Walther by rough terrain. Much of its northern rim was destroyed by Purbach's impact. There is a crater on its almost non-existent northern wall. Two ghost craters go southward through the middle.

 

Above Deslandres..... that's Rupes Recta aka the Straight Wall! As the absolute best example of a lunar fault, Rupes Recta casts a wide shadow that gives it the appearance of a steep cliff. The fault has a length of 110 km, a typical width of 2–3 km, and a height of 240–300 m. Although it appears to be a vertical cliff in the lunar surface, in actuality the grade of the slope is relatively shallow.

Thebit (circular crater with most of its floor in darknesss in middle left), Thebit A with its highly illuminated rim, the small Thebit L beside A, the even smaller Thebit J nested beside Thebit, and Rupes Recta! Thebit A appears to have impacted both Thebit and Thebit L.

The crater Birt is the illuminated crater in the shadows. Promontorium Taenarium was very large and well illuminated at the south end of the Wall; an intermittent ridge line ran from Thebit J to the south end of Rupes Recta, creating what looked like a break in the Wall just before the Promontorium. A few ghost craters appear on the Mare Nubium floor, suggesting inflow from volcanic action at some point.

  

At 10 o'clock to Thebit is Arzachel, one of a set of four on the Mare Nubium shores. The other three above it are Alpetragius, Alphonsus and Ptolemaeus.

Arzachel has terraced walls; you can certainly see that on the lit side. It has a long central peak and the small Crater A is on its floor close to the peak and you can just make out an even smaller Crater K nearby. There is a rough outer rampart that joins a ridge running from the north rim to southern rim of Alphonsus. Note: Its floor is 1.5 km below that of Aphonsus's.

Alpetragius is the small crater lying to the side between Arzachel and Alphonsus. The bowl of the crater is in darkness but its rim is well illuminated. Had the floor been lit, you would have seen the central peak that takes up about 1/3 of the floor; this has lead tot his crater being referred to as "egg in the nest".

Alphonsus has a central peak. The outer walls are slightly distorted and possess a somewhat hexagonal form. The grooves seen on its floor are similar in appearance to those of Regiomontanus, and are thought to be due to Imbrium's ejecta gouging out the highest points of the terrain. Its southern rim has the rampart that joins it to Arzachel. Note: Its floor is 1 km below that of Ptolemaeus.

Ptolemaeus is the largest of the craters in this chain. No central peak but it does have the named crater Ammonius on its floor. It has a low, irregular outer rim that is heavily worn and impacted with multiple smaller craters. The crater has a lava-flooded floor that under certain light shows ghost craters where lava covered pre-existing craters there.

The small crater above Ptolemaeus is Herschel; you can see the top of the central peak in this deep round crater and hints of a terraced wall. You can also see the small Herschel G attached to the SW rim of Ptolemaeus.

I then just started looking at the eastern limb of the Moon especially in the area of Mare Crisium. Lots to see!

Mare Crisium (Sea of Crises) fills the central portion of this image. The craters in Crisium - Pierce and Picard - look like two eyes and, combined with Proclus and its ejecta rays, I see a bear's eyes, snout and nose. Proclus is thought to have hit the moon obliquely thus creating the ejecta rays towards Crisium and not Palus Somni, the rather grey fan-shaped area.

On the limb at 9 o'clock is an oblique view of Mare Marginis (Sea of the Edge). Appropriately named given its location.

At 5 o'clock to this is Mare Undarum (Sea of Waves). It's a shallow mare formed by the impact that created Crisium. The western part of Mare Undarum forms - with a little imagination - a footprint.

Between this Mare and Crisium are three dark areas. From North to South these are the craters Condorcet, Firmicus and Apollonius. Signs of their "true" crater-ridden floors are long gone; their dark floors suggest lava filling.

At 5 o'clock to Undarum is Mare Spumans (Foaming Sea). If you look closely at this image you will see a bright white spot on the mare shore.
     

Interesting factoid: This bright area was known as landmark A-1/11(1.7981° N, 65.0741° E). Astronaut Michael Collins tracked this landmark on revolution 4 of Apollo 11. Collins referred to this crater as KAMP, after his three children and wife (Kate, Ann, Michael, and Patricia).  

Mare Fecunditatis (Sea of Fertility) fills the lower right of the image. 

Montes Secchi separate it from the  Mare Tranquilitatis (Sea of Tranquility) above it.

That was it for my reacquaintance session. Had fun doing this and re-identifying some really cool features.

Date: 2024-06-13
Time: 8:45 PM - 11:00 PM ADT
Equipment: Visual, 10x42 IS Binoculars
Transparency: not recorded
Seeing: not recorded

I was a bit tired when I arrived for this session so energy to seek out objects was low, and recording of observations were minimal and those of light levels, temperature, seeing and transparency went by the wayside.  Jerry and I were with David Hoskin, Stephen Payne, Tony McGrath, Meredith and Dennis. Fairly clear and no wind to speak of. Around 10:15 PM, fireflies were twinkling at the shoreline near the Storeroom.

Waxing Moon (48.1%)
Time: 9:30 PM ADT

Equipment: Binoculars
Several craters were located west and southeast of Mare Nubium near the terminator:

  • Albetagnius with its interior crater Klein
  • Hipparchus with Horrocks - the latter had a very bright rim and dark floor.
  • Maurolychus
  • Barocius
  • Stoffler


Time: 9:58 PM ADT
Equipment: Binoculars
There were several features observed this evening. One of my favourite craters, Proclus, shone brightly to the west of Mare Crisium as did its ejecta rim. Adjacent to it was Palus Somni - a fan-shaped, rough-surfaced, greyish formation on the shores of Mare Tranquilitatis. 

Bright Stars
At this point I was just looking for stars that could be seen visually and when they appeared.

Time: 9:50 PM ADT
Equipment: Visual
At this point, all 3 stars of the Big Dipper handle (Alioth, Mizar and Alkaid), Arcturus in Boötes, and Spica in Virgo were shining brightly and easily identified.

Time: 10:00 PM ADT
Equipment: Visual
The handle plus the 4 stars of the bucket in the Big Dipper (Megrez, Phecda, Merck and Dubhe) were visible.

M49 / NGC 4472
Time: 10:51 PM ADT
Equipment: Binoculars
I attempted to find M49 in Virgo by identifying Vindemiatrix and Porrima. M49 formed a triangle with these two stars but with the almost 50% Moon it could not be found.

I was in the general vicinity after looking at M4. I slewed to find M80 above Antares with the 9mm eyepiece. I did not use the 10-30mm eyepiece colocate this as I had done other clusters this evening - and I found it!

It had a dense core and was much better seen with averted vision to obtain details of its structure. There were no especially bright stars in the core that I could see but the nebulous halo suggested stars of this cluster went a distance from the core.

I used the 40mm initially to find Antares and the general area for M19. I then switched to the 10-30mm zoom eyepiece. I found it with the 30mm but it was quite small and had no distinguishing features. At 10mm, there was a much better view of the dense core; noted that was less dense than that of M62. The stars outside the core/nebulosity created by the cluster's star field was discernible for a short distance from the core.

Note: I had challenges labelling the sketched stars around the cluster; therefore, left them all unlabelled. First time I've ever had that challenge.

We were a little later than expected by about 1 hour due to 4 road construction delays, one as long as 20 minutes. It was a pleasant paddle across the lake with only slight ripples but enough breeze to keep the flies off. As is the custom, we unloaded the canoe content onto the beach and had lunch before setting up camp under the trees. An afternoon swim and some time on the beach made for a wonderful afternoon and early evening. However, I may have had too much sun because I wasn't feeling well by the time dinner rolled around. Thankfully, I felt well by the time the skies started to darken.

Jerry and I were alone on the island this evening; our friends were expected around noon tomorrow. When I was on the beach earlier, I determined what to look for in this observing session. There was high cloud. No wind to speak of but at least the mosquitoes were gone! Spring Peepers were calling out at the south end of our island and frogs were responding on the shores of Minard Island opposite our site. The lake surface was like glass with only an occasional fish near shore breaking the surface.

It was here that I decided to fire up the telescope. Alignment is still a skill I'm learning with this scope. In the first attempt, I used Castor and Arcturus. Thought I had it operational but then lost the connectivity between the scope and my phone. Bah. Humbug. It was also about this time that the sky got brighter in spurts; we attributed it to the fireflies or to lightning way off in the distance that may/may not be approaching us. Turns out it was the thunderstorm in St. John, NB that was lighting up our skies intermittently. (Note: we only had a slight drizzle overnight as a result of that storm passing through.)

10:39 PM ADT (Visual)
Slight occasional breezes. Fireflies are now frequently making their presence known in the trees. 
- all 7 stars of the Big Dipper were very easily located
- Leo's Regulus plus 5 stars of the 'sickle' were seen above the trees on the island across from us.

The Dipper was so clear on the NW horizon. After identifying Muscida, I decided to identify the remaining stars of the constellation especially since the bear was literally pointing down towards the horizon. The stars were so clear, I was able to do this visually; no binoculars were required. I used the star chart to identify the names of the stars I sketched. I remembered the Talitha and Talitha Borealis from the observations of the 2020 comet C/2020 F3 (NEOWISE) while at Dr. Roy Bishop's cottage. 

Ursa Major

It was here that I decided to make another attempt, this time with Antares in Scorpius and UMa's Dubhe. Success! And no lost connectivity. Consequently, I decided now was the Messier time. I knew there were three near Antares so had the scope go to Antares.

S&T Chart: 56, 58
I began with the 30mm aspect of the eyepiece then gradually increased the magnification 5mm at a time. At 10mm, I saw the cluster east of Antares. The cluster had a dense core but not as dense as that of M62. A nebulous star field was discernible for a little distance from the core. For more details, refer to Messier Catalogue - M019 / NGC 6273 - June 5, 2024.

Not changing the eyepiece from the previous Messier object, I slewed the scope from M19 towards ε Sco to find this cluster. It had a denser core than M19 but t was not as bright. For more details, refer to Messier Catalogue - M062 / NGC 6266 / Flickering Globular Cluster - June 5, 2024.

It was while I was sketching M62 that three owls hooted - 2 Barred Owls sounded their recognizable "who-cook-for-you" whereas the third owl spoke a language other than English. I did not recognize its hoot - maybe a different genus of owl or maybe a youngster. The peepers started up again after a period of quiet. Then a coyote howled; we joked that it was complaining about the owl and peeper noise that made sleep impossible. The fireflies never disappeared and gave us smiles many times throughout this session.

Time: 12:10 AM ADT

This cluster is located above and on the opposite side of Antares in Scorpius from M4. It had a very dense core and was better seen with averted vision. For more details, refer to Messier Catalogue - M080 / NGC 6093. 

12:30 PM ADT
Two loons were calling out across the Lake as I was sketching M80. Love their call; it's such a soothing sound in the dark. The constellation Leo was just above the island across from our beach at a 45° angle to the horizon, making it look like Leo was doing a face plant. Boötes was still quite high in the sky with Arcturus very much evident.

Time: 12:42 AM ADT
Equipment: Visual, Binoculars
S&T Chart: 67, 69
I noticed the Teapot for the first time this evening. It was almost flat on the south horizon. Using the lid star (Kaus Borealis), I used my binoculars to locate the Y-shaped star formation and M22 adjacent and to its east. It appeared as a small grey fuzzy.

Time: 1:07 AM ADT
Equipment: Visual, Binoculars, Telescope
Eyepieces: 9mm, 30mm-10mm
S&T Chart: 67, 69
I realized the Teapot was high enough on the horizon that I should be able to find M7. Found its location with averted vision with no aids, then used my binoculars to look at this glorious open cluster. With the 9mm eyepiece in the scope, I slewed the scope down about 15° to the area about 5° west of Kaus Australis. I discovered that only the core of the cluster could be seen at this higher magnification. I exchanged it for the zoom eyepiece and beginning at 10mm gradually increased it to 30mm - and that is when all of the cluster could be seen. Unfortunately.... 

I noticed the horizons were beginning to get murky and clouds were filling in our overhead view. I had pencil and clipboard in hand to begin sketching this wondrous object when the clouds completely covered M7 and the Teapot. Skies at the zenith were now more cloud covered with no hope of a large sucker hole to get any views of any other entity. Disappointment - but glad to have achieved what I did.

It was very easy to slew from Antares to find this cluster. Not as dense as M3, i.e., no dense core. Had to use averted vision to sketch. Although no identifiable core, there were a few bright stars near the centre and southern portion of the cluster. However, I could sketch their exact location. There were three stars forming a triangle that I could not identify.

I had two astro-imagers with me - Jerry and Bob. No wind and absolutely cloudless skies until 1:30 AM when clouds and/or fog rolled in around the periphery of the viewing field. We had actual cloud cover when we were about to leave SCO - something that had not been forecasted. Throughout the observing session, we stated our frustration of the satellites criss-crossing the skies and spoiling our views (visual, binocular, telescope, camera).

I spent the first part of the evening setting up and getting reacquainted with my telescope and getting re-oriented to the SCO skies. 

M3
Time: 10:26 PM - 11:04 PM

Equipment: EvoStar 80 ED telescope
Eyepiece: 10mm-30mm

S&T Chart: 43, 44
I have located this one in the past but wanted to make a definitive entry in the Messier Catalogue. I had the scope go-to Arcturus that was very bright in this night's sky. From there I slewed towards β Coma Berenices. Given the smaller aperture and slower speed motor, it took a while; I became frustrated at my lack of ability to manoeuvre the scope in the correct direction. Eventually, I thought to use SkySafariPro to identify M3's surrounding star field. I then used the 30mm feature of the eyepiece to provide a wider FOV to locate M3. Once located, I slowly increased the magnification all the while refocusing and ensuring M3 was centred. Had to use averted vision to get a better view of this object.

M3 has a very dense/bright core in which individual stars could not be resolved, but the core did take most of the area of the cluster. As the density became less towards the cluster's edge, the star field looked nebulous.

Following the frustration with finding M3, I decided to use my eyes to identify constellations and to orient myself to the SCO skies again. I knew what constellations in which the Messier objects I wanted to view tonight were located but just had to see whether or not they were "up" and not blocked by our tree lines.

Corvus
Time: 11:30 PM

Equipment: Visual
S&T Chart: 47
All five of the main stars were easily identified above as string of stars that I later discovered belonged to the constellation Hydra.

M4 / NGC 6121 / Spider Globular Cluster
Time: 12:04 AM - 12:11 AM
Equipment: Visual, binoculars, EvoStar 80 ED telescope
Eyepiece: 10mm-30mm eyepiece

S&T Chart: 56, 58
Scorpius had come past the trees and was now quite visible except for her tail stars. Antares was visibly red. I knew from past experience that M4 formed a triangle with Antares and σ Sco (Al Nayat). I used my binoculars to affirm I still knew how to find it.

With the telescope, I slewed west towards Scorpius from the treeline to find the very bright and red Antares. Using averted vision, I was able to locate M4. It was quite diffuse; it did not have an identifiable dense core that M3 had. There were a few bright stars in the centre that could be seen but I could not sketch there exact location.

 

Corona Borealis, Keystone of Hercules, M13
Time: 12:22 AM

Equipment: Visual, Binoculars
S&T Chart:52, 53, 54, 55
I truly enjoy finding Corona Borealis with its unmistakable bowl shape. All 7 stars were readily found somewhat high in the sky. Alpheca (α Sco) was the brightest by far. Surprisingly this was followed by γ Sco then δ Sco. The other stars were rather dull in comparison. I then visually located the Keystone of Hercules. Using the stars of the Corona to point the way to M13, I used my binoculars to find the small grey fuzzy - liked finding an old friend in the crowd.

While in the process of packing up, Bob and I did a quick "what's up". I pointed out Shaula in Scorpius that was now visible. We noted how high the Keystone of Hercules was in the sky and also noted the skies were deteriorating along all the edges of SCO's FOV.

I had found this in the past with binoculars. Tonight I had the scope go to Arcturus then I slewed towards Coma Berenices. I used SkySafariPro to help identify the star fields on the way there. I began with 30mm eyepiece so that the FOV would in essence be large. Once found, I centred M3 and increased the magnification to x60 with the 10mm feature of the eyepiece.

M3 has a very dense core and its brightness finished very quickly outside fo the core. Had to use averaged vision at times.

Comet C/2023 A3 (Tsuchinshan-ATLAS) - October 11, 2024

Comet C/2023 A3 (Tsuchinshan-ATLAS)
1st Quarter Moon

Sunset at windy Peggy's Cove - Venus shining brightly.

Location: Peggy's Cove, NS

We drove to Peggy's Cove after an early dinner. Jerry had a camera plus tripod plus his iPhone 15 Pro Max. I had my 10x42 IS binoculars plus my iPhone 13 Pro Max.

We arrived earlier than necessary as we wanted to set up and to watch the sunset that is normally quite beautiful at that location. 

Joining us were Fellow Lady Observer Liz with her two cousins (Helen and her brother John David). There was a cold wind that was quite noisy in my ears when facing the wind with my hood up. Very thankful I had winter coat and mitts! We found some respite behind one of the wood fences of the deck, and that helped (a bit).

We thought about leaving as it got darker and no comet was evident in the sky, but were determined to stay until we found it or it was too dark to find it.

At 6:38, we found it! Persistence paid off. Barely visible in the colours of the sunset but nonetheless there. 

Jerry captured it with his camera (photo at left).

The rest of us enjoyed the view with our binoculars. It appeared in the pale orange band of the sunset. Did not see much of the tail but the comet appeared to be fuzzy - not sure if because of the tail obscuring it or the unsteadiness of the atmosphere.

Now to track it over the coming month....

Equipment: 10" Meade SCT, Fountain binoculars with 20mm eyepiece
Magnification: x120
Temperature: 11° C
Seeing: Good (3)
Transparency: Good (3)

Jerry and I were in the back yard planning an evening of experimentation with the newly-acquired Fountain Binocular eyepiece. I had plans for another IWLOP season as well. Impressed with the binocular eyepiece but also have to be mindful of the different settings required for Jerry's and my eyes.

I used the binoculars to complete the IWLOP L5: Gartner & Democrius. With that eyepiece in place, I wanted to show Jerry a few cool features that were very readily and clearly seen.

1- With Democritus and Garner in view, we could plainly see Vallis Alpes cutting through Montes Alpes. The mountains showed their ruggedness with highlighted peaks and long shadows on Mare Imbrium.

2- Altai Scarp was bright white, even against the sun-drenched surroundings. The SE end was at the edge of Piccolomini and arced irregularly northward with no real end spot. Tacitus was to its west/north end.

3- Near Altain Scarp were "sets" of craters that are fun to see:
         a-  Ptolomaeus, Alphonsus, Arzachel - The latter's central peak was very evident.
         b- Area of the Lunar X - Purbach, Werner, Regiomnontanus, Walter, Alciensus. Much of their crater rims were lit but no sign of the "X".

IWLOP CAN1 - Avery (Canadian Connection)

Named for Oswald Avery (1877-1995), born in Halifax, NS. US Physician and DNA researcher.

A bowl-shaped impact crater on the edge of Mare Smythii [L3], west of Haldane. Former name Gilbert U. Libration Object.

Diameter: 9 km     Rukl: 49 & IV

Objects: Avery, Haldane, Mare Smythii

Location: Home
Date: 2024-05-15
Time: 10:25 PM ADT
Equipment: 10" Meade SCT
Eyepiece: 20mm Founder binocular eyepiece
Magnification: x120
Temperature: 11° C
Seeing: Fair (2)
Transparency: Fair (2)

Because of the liberation, Avery did not appear to be round. It was a small crater west of the longer Haldane, and it was so exciting to realize that little crater was the object of this search. Don't think it was very deep but that perception may have been due to the libration and the amount of illumination.

Eyepiece: SvBony 20mm 70º FMC with lit reticule
Magnification: x120
Seeing: Fair (2)
Transparency: Fair (2)
SQM: not recorded
Temp: 11º C

Moon now in Leo. This was the first time I was using by Founder binocular eyepiece. I was impressed, but do have to be mindful to getting the binoculars set up for my eyes versus Jerry's eyes.

C1: Democritus was on the shore of Mare Frigoris above Gartner. Democritus had a very high central peak, was circular in appearance, had a light-coloured floor compared to Gartner, and its rim was visible around the entire crater. Gartner had no rim to the SE and only a little to the SW. The remaining crater walls appeared tall. Its floor was dark, similar to that of Mare Frigoris.

Note: Libration was not favourable to view Cusanus and Petermann.

IWLOP CAN5 - Daly (Canadian Connection)

Named for Reginald Daly (1871-1957), born in Napanee, Ont. Highly honoured Harvard professor of geology.

Impact crater NW of Apollonius. Former name is Apollonius P.      

Diameter: 17 km     Rukl: 38

Objects: Apollonius, Daly
Other Objects: Apollonius F, Fermicus

Location: Home
Date: 2024-05-14
Time: 9:30 PM
Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 12mm 92° FOV

Magnification: x209
Temperature: 13° C
Seeing: Good (3)
Transparency: Good (3)

The atmosphere had slight turbulence so this crater came in and out of clarity. It appeared as a white-rimmed double crater then realized it was Daly with Apollonius F.

I looked at my lunar maps to find/locate it between Apollonius and Fermicus, and moved NW to the former. I found two craters in my slewing SE of Mare Crisium, then recognized that one was Daly.

No breeze and clear skies. Orange-brown smoke from Alberta fires could be seen as two bands in the WSW horizon. Jerry had left for SCO to work on the 8" scope but not before setting up the 10" Meade SCT and refreshing my memory on its use. It had been a while since I had last worked on the RASC IWLOP and I had hoped to get:

  • #15: Promontorium Lavinum and Olivium
  • #21: Sinus Concordia
  • #26: Rupes Cauchy and Cauchy Domes

I very quickly realized I had picked the wrong Q-day! Although it was easy enough to find the area the objects were located, they were too illuminated to really observe their features.

What does one then do? You play with the various eyepieces from 4.7mm to 40mm and x2 Barlow. Focusing with the Barlow was a challenge! I then realized that the SE limb was librated so looked at what was showing (i.e., what I could identify). It helped to use the mirror-image S&T Lunar map, not the standard one. 

What was identified:

  1. Rheita
  2. Vallis Rheita
  3. Steinheil
  4. Watt
  5. Reimarus

General Session - April 8, 2024 (Solar Eclipse)

Sun
Moon

This entry in my observing log not only covers what we saw at the eclipse but also family fun leading up to the event.

Location: Texas Wine Collective, Blumenthal, TX (near Fredericksburg)
Date: 2024-04-08
Time: 11:30 AM - 3:30 PM CDT
Equipment: 
    a- Visual (with solar glasses)
    b- 10x42 IS Binoculars (with solar filter)
    c- EVOSTAR 80ED with a star diagonal plus SvBony 10mm-30mm zoom eyepiece (set at 20mm)
    d- ZWO SeeStar S50 (Brady)
Temperature: 26° C - 23° C

We arrived in Austin TX on April 5 (30° C) to visit our nephew Brady and to take in the solar eclipse.  It was a wonderful excuse for our families to get together. Barbara and Barry arrived just 20 minutes (not 4 hours as planned) before us. Barry apparently made a wrong turn and it wasn't until they started seeing advertisements for New Orleans that they realized they were headed east not west. After unpacking our cars, we spent the remainder of the day relaxing on Brady's deck, and usually with a wine glass or cold cider in hand. Great start to our time together!

On April 6, we headed to Driftwood TX to one of our favourite restaurants - the Salt Lick Texas BBQ. We weren't disappointed! It was as good as we remembered it from our previous visit six years ago. Their smoke pit could be viewed as you walked into the main seating area, their smoked sausages, turkey, brisket and ribs on display. Your choices of meat came with coleslaw, potato salad and baked beans, all made on site (as was their BBQ sauce). So yummy!

 
On the way home, Brady took us past a field of Bluebonnets (either Lupinous texensis or Lupinous subcarnosus that are native to Texas) that very much looked like our northern Lupine.   

On April 7, following a tour of his home gardens, Brady treated us to homemade pizza baked in his outdoor pizza oven. Each of us decided what meat and veggies we wanted on our personal pizza then got to enjoy it fresh and hot out of the oven. What a treat!

Later that evening, in honour of the eclipse taking place the next day, my favourite pianist/composer, Rachel Lafond, and a collaborator and fellow pianist, Scott D. Davis, held a private concert in her home. It was a wonderful evening of humour and such beautiful music. If you closed your eyes as they played, you could 'see' what the music was saying. Rachel introduced 3 pieces about the decision to start and to continue a personal relationship; it was emotional. Scott introduced a piece he wrote following a backcountry hike (alone) up to a bare mountaintop then realized a lightning/thunderstorm was approaching. You could hear/feel the storm approach and overtake him. An evening of memories to treasure forever. 

April 8. Eclipse Day! With telescopes, binoculars, cameras and picnic basket packed, we headed to the Texas Wine Collective where we would be potentially joined by 495 others at the site. Traffic was much lighter than anticipated so we made good time. The Collective was very well organized and in no time we were parked and had selected a place to set up. Brady had his SeeStar set up; I had my EvoStar 80ED up and tracking the sun and had binoculars at the ready. Barry and Barbara had solar glasses and binoculars. While waiting for the Sun to be Mooned, we met two small groups adjacent to us. One was a couple from California who had flown in and the other was a family from New Jersey who drove down; the former had binoculars and the latter had a telescope set up. It was the first total eclipse for all of them so provided a little info as to what to expect and when.

 

My telescope was set to track the Sun but the cloud cover obscured the view at times. Leading up to the event, we certainly were able to use our solar glasses to safely determine where the sunspots were located. Then I used my telescope and binoculars to sketch their location - interesting difference in orientation. As seen in the perspectives sketched, the large sunspots were just off centre and a pair of sunspots were near the edge of the limb - binocular view on left, telescope view on right.  
       

The large central sunspots were covered by the Moon at 1:01 PM CDT. AS it was getting darker and closer to totality, a group of "cheerleaders" began to chant in their attempt to chase the clouds away - too bad it didn't work. Totality was at 1:35 PM. It was then that the place burst out in cheers. The astronomer in attendance from the University in Austin must have informed the group as to when that was occurring.  The Collective had made sure their lights would not come on during totality but the adjacent property's entrance gate lights came on and beautifully accentuated the darkness.

Because of the increased cloud cover, I decided to view post-totality with my binoculars as it was becoming increasingly difficult to see the sun through the clouds in the EvoStar. 

       

Thankfully, Brady caught totality in a short time-lapse captured with his telescope that included an excellent view of the prominences. It became very dark at totality and the temperature dropped at least 3 degrees or more. What we didn't see at totality was the corona, the diamond rings, nor Bailey's Beads. However, the eclipse effects were felt physically and emotionally. Although the last contact was to be at 2:58 PM CDT, the total cloud cover convinced us it was time to pack up 45 minutes early. Had to take a small detour because of traffic heading back into Austin but otherwise an uneventful trip. Once back at the house, we broke open Nova Scotian Benjamin Bridge Nova 7 wine and regaled our experiences with the eclipse. Not what we had hoped to see but none-the-less an experience we enjoyed. 

So, where to next? Spain in 2026? Australia-New Zealand in 2028? The planning begins.

solar totality
Totality!
Celebration! RASC t-shirts and Nova Scotia wine!

General Session - April 1, 2024 (Comet 12P/Pons-Brook)

Comet: 12P/Pons Brook
Constellation: 
Aries

Stars: AF Arie, k Ari, l Ari, q Ari, 10 Ari, 11 Ari, 14 Ari, 15 Ari, 17 Ari, 20 Ari, 21 Ari, Hamal

We received the following email from Dr. Roy Bishop via the RASC Halifax Centre Discussion List:

If you have not yet seen Comet 12P/Pons-Brooks, early this evening is an excellent opportunity.
Last evening the comet was less than a degree to the left of mag 2 Hamal (alpha Arietis), making a pretty pair, side-by-side low in the WNW sky as darkness settled in. This evening the comet will be further from Hamal, but still less than two degrees to the left of the star. With Hamal flagging it, the comet will be easy to locate in binoculars.

Pons-Brooks displays a visible tail about half a degree long, extending straight up from the horizon, detectable in binoculars, and obvious in my 444-mm telescope last evening. The concentration of its coma was about 6 on the Levy scale (see p. 265 of your Handbook). I estimated the magnitude of the comet to be 4.5.

Comet Pons-Brooks has a 70-year period, and given the clouds of the next few days, and evening twilight extending ever later day-by-day, this evening around 9 p.m. may be your last chance to see it. You will need a low WNW horizon, for at 9 p.m.Hamal’s altitude is not much more than 12 or 13 degrees. Start looking for Hamal by 8:30 or 8:45.

Because Roy gave us the heads up, Jerry and I hurried to our bedroom window with binoculars in hand (much warmer than going outside) and looked WNW - et voila!

The round fuzzy was adjacent to Hamal in Aries, as promised. While viewing it, I sketched the star field. So exciting to see it so well; being slightly elevated above the ground level of our backyard certainly helped us to observe the comet.

This was the second night of our Annual Big Muise Island Star Party at Site 15. Jerry was setting up his cameras for time lapse while Dave and I set up our chairs and waited with binoculars in hand. A light wind disappeared by midnight. No clouds throughout this session.

Moon, Venus (in Leo)
Time: 8:00 PM
Equipment: Visual
Venus as now 8 o'clock to the Moon and about 10° away. It was a beautiful sunset with a lone loon calling in the distance.
   

9:48 PM
Arcturus appeared in the southwest.

10:00 PM
Antares was twinkling in the southeast above the far end of our island. We also noticed Spica shining below Arcturus in the SW.

10:05
Three stars in the Dipper Handle made their appearance - Alkaid, Alcor-Mizar and Alioth.

Mars! Venus!
Time: 10:08 PM
Equipment: Visual
Very tiny and very red! It was half way and just below the line between the Moon and Venus.
 
 

Scorpius
Time: 10:12 PM
Equipment: Visual, Binoculars
S&T Chart: 58, 58
Antares was still quite bright. Could also identify Graffias, Dschubba, π Scorpii, σ Scorpii. However, could not see M4. The tail section was still behind trees at the end of the island.

Leo, Spring Triangle
Time: 10:17 PM
Equipment: Visual
S&T chart (Leo): 34, 35
Denebola was just noticed in the W-SW. All three starts of the Spring Triangle were now visible - Arcturus (α Boötis), Spica (α Virginis) and Denebola (β Leonis). Interestingly, Vindemiatrix (ε Virginis) is the centre star in that triangle of constellations.

Libra
Time: 10:30 PM
Equipment: Visual
S&T Chart: 46, 57
Brachium (σ Librae) and Zubenschemali (β Librae) were one above the other in a vertical line. Both were very faint.
   

Big Dipper
Time: 10:38 PM
Equipment: Visual
S&T Chart: 31, 32, 33, 43
All 7 stars of the Big Dipper were now visible in the NW.

Centaurus
Time: 10:51 PM
Equipment: Visual, Binoculars
S&T Chart: 48, 59
This is a constellation that one never expects to see this far north - but there it was. Dave was excited to see it in the S-SW. Menkent (θ Centauri) was viewed with binoculars to determine the star field nearby. There were 3 stars in a line to the south - α Centauri, ψ Centauri and HR 5357. There were three stars in a triangle northwest to this star - 2 Centauri, y Centauri and z Centauri. Very exciting to see this constellation that I first saw when in the Atacama Desert all those years ago.

Corona Borealis
Time: 11:00 PM
Equipment: Visual
S&T Chart: 53, 55
All 7 stars of this constellation were located - Alpheca (α Coronae Borealis), Nusakan (β Coronae Borealis), θ Coronae Borealis, γ Coronae Borealis, δ Coronae Borealis, ε Coronae Borealis, ι Coronae Borealis. Normally I would use this constellation to locate Hercules and M13 - but not tonight.

Scorpius
Time: 11:55 PM - 12:00 AM
Equipment: Visual, Binoculars
S&T Chart: 58
I directed my attention to Scorpius' tail. Using Binoculars, I could easily identify Shaula (λ Scorpii) and the adjacent HR6441. μ1 Scorpii and μ2 Scorpii were on the other side of the tail section and were at the same declination.

There were fireflies in the trees above me; initially I thought it was stars shining through the branches.

False Comet
Time: 12:02 AM - 12:20 AM
Equipment: Binoculars
S&T Chart: 58
I directed my attention to a specific part of Scorpius' tail known as the False Comet. I had first been introduced to this asterism when in San Pedro de Atacama (by Dave, by the way) and he was now observing it and its various components again with me.

  • Collinder 316: Saw 7 bright stars with numerous others not as bright in a nebulous background.
  • HR 6272
  • V973 Scorpii: near the 'border' of Collinder 316. 
  • NGC 6231: below Collinder 316.
  • ζ1 and ζ2 Scorpii: Below NGC 6231; the stars were parallel to the horizon.

M10 & M12
Time:  12:35 AM
Equipment: Binoculars
S&T Chart: 54, 56
Ophiuchus was up high enough that I thought to try locating these two Messier objects. M12 was located by starting at Marfik and heading southward. M10 was found about another FOV away. Both were small, grey fuzzies. Happy I could find them both.

Libra
Time: 12:45 AM
Equipment: Visual
S&T Chart: 46, 57
All 6 stars of Libra are now visible. I had not realized until now how close the 'scales' were to Scorpius.

Time SQM Temp
10:45 PM 21.46 17° C

Dave and I were in our camp chairs with binoculars at one end of the beach while Jerry was at the other end setting up his camera gear. There was a light breeze - enough to keep the mosquitoes away!

Moon, Venus, Mars
Time: 9:19 PM
Equipment: Visual, Binoculars
The Moon and Venus were up fairly high in the skies. Visible were Mare Crisium, Gang of 4 (Langrenus, Vendelinus, Petavius, Furnerius), Cleomedes, and Geminus. Earthshine was evident on the lunar surface.

Venus was 8 o'clock to the lowest part of the crescent Moon. Marrs was at 10 o'clock to Venus and higher than the top of the crescent Moon.

Boötes
Time: 9:30 PM
Equipment: Visual
S&T Chart: 42, 44, 53, 55
Arcturus shone brightly and was easily spotted. I looked for and found the kite-shape of this constellation but did not identify the individual stars.

Scorpius, Centaurus
Time: 10:19 PM
Equipment: Visual
S&T Chart: 56, 58
The reddish Antares was twinkling  in the southern horizon. Could readily find Graffias (β Scorpii), Dschubba (δ Scorpii), and η Scorpii. At this point, I did not search for other stars within the constellation. It was at this point of the evening that Dave excitedly pointed out Menkant (θ Centauri) just above the horizon. Menkant is part of the shoulder of the Centaur. What surprised us is that Centaurus is considered a "southern" constellation so to see it here was a wonderful surprise.

Spring Triangle, Great Diamond/Diamond of Virgo
Time: 10:25 PM
Equipment: Visual
Dave pointed out two asterisms. Arcturus (α Boötis), Spica (α Virginis) and Denebola (β Leonis) comprise the Spring Triangle. Interestingly, Vindemiatrix (ε Virginis) is the central star in that triangle of constellations. Denebola (β Leonis), Arcturus (α Boötis), Spica (α Virginis) and Cor Caroli (α Canum Venaticorum) comprise the Great Diamond. Two asterisms in one part of our observable skies! Who knew?

10:45 PM - 11:30 PM
It was during this time that for some reason I stopped recording times of observations, so here's the list. 

Teapot
M22 / NGC 6566

M8 / NGC 6523 / Lagoon Nebula
M20 / NGC 6514 / Trifid Nebula
M21 / NGC 6531 / Webb's Cross
M7 / NGC 6475 / Ptolemy Cluster

Equipment: Visual, Binoculars
S&T Chart: 67, 69
The Teapot asterism was above the horizon about 10° and its base was almost perfectly parallel to the horizon. All 8 stars were easily seen. 

I used binoculars to find M22 by starting at Kaus Borealis (the Teapot lid star) and moving at bout a 45° angle to find a small group of stars that were Y-shaped, then moved a little further out to find the small grey fuzz of M22. 

I then used the stars forming the spout - Kaus Media (δ Sagittarii) and Alnasl (γ2 Sagittarii) - to find M8, M20 and M21. Just viewed them long enough to recognize the binocular-view shape and star composition. Did not sketch.

I then went to the base of the Teapot and used the line from Nunki (star in the Teapot handle) to Alnasl (star in the spout) to continue outward to find M7. I was not disappointed! The Ptolemy Cluster is a glorious open cluster - bright and many stars.

I went out this evening with the intent of only viewing the comet. Dave Chapman had posted it was near ω Aur so started the search with my 

my binoculars, going downwards beginning halfway along the line from Capella to Al Kab.

I found a round pale smudge - the comet - above the star that was 1 of 3 forming a curve (HR1573, 2 Aur, 1 Aur).

Windless and no clouds.

The promise of a clear night was realized and Jerry was already taking time-lapse of the Comet. So, with clipboard, paper and pencils, red light to clip to the clipboard for seeing what I sketched (thanks, Melody), and my binoculars, I headed out to join him in our back yard. 

First thing that came into view the moment I opened our back door was Orion, high in the sky above our tree line and its bright stars very evident in the dark skies. With Orion so high, I looked for the full Winter Circle - found! Turned about 45˚ to locate Cassiopeia, Ursa Major and Ursa Minor. The latter constellation was the one of primary interest given the comet wasn't too far away from Kochab. The only stars I could see in the Little Dipper were Pherkad, Kochab and Polaris (mag 2.0); with averted vision, I could see (imagined I saw?) Urodelus and Yildum in the handle and the other two stars of the dipper (Anwar al Farkadain, Alifa al Frakadain) - but they were very faint.

Using my 10x42 IS binoculars, I located Pherkad (mag 3.0) and Kochab (mag 2.0), noting 11 UMi (mag 5.0) next to Pherkad and HD133086 (mag 6.8) and TT UMi (mag 6.9) next to Kochab. With Kochab in my FOV, I had to go up just bit and to my right (east) to find it. A fuzzy cottontail, no tail with this equipment could be discerned. I then used my garden planting table as my easel to sketch it.

Using my 10x42 IS binoculars, I located Pherkad (mag 3.0) and Kochab (mag 2.0), noting 11 UMi (mag 5.0) next to Pherkad and HD133086 (mag 6.8) and TT UMi (mag 6.9) next to Kochab. With Kochab in my FOV, I had to go up just bit and to my right (east) to find it. A fuzzy cottontail, no tail with this equipment could be discerned. I then used my garden planting table as my easel to sketch it.

It was then that I turned my attention to other sights. First was the 5 stars of Cassiopeia above our greenhouse. I thought, "Perfect! I can easily find Andromeda." Wrong (and disappointing)! Andromeda was lower than thought and lost in the light pollution of our neighbour's backyard light that can be obscured by our shed and greenhouse if you stand in the right spot.

   

 

Leaping Minnow
Leaping Minnow from Binocularsky.com 

Oh, well, Auriga is high and I can see it's bright 5 stars, especially Capella. Up with the binoculars to find the asterism Leaping Minnow. Several stars within Auriga comprise the asterism - 19 Aur beside 18 Aur, 17 Aur beside IQ Aur, 16 Aur beside HD 34201, and 14 Aur. All in close proximity.

Also close by and located with only a slight adjustment in declination of the binoculars were M38 (Starfish Cluster) and M36 (Pinwheel Cluster). Did not search for M37, nor did I sketch any of the objects just seen.

I looked up again at Orion with binoculars to M42. I could see the nebulosity around its four stars but could not discern the two stars within θ1 Orionis and θ2 Orionis as I had January 11 using my 10" Meade SCT.

I then turned 90˚ to the East to see Leo advancing high above the neighbour's roof. Denebola and Regulus as always stood out but I could also readily identify Zosma and Chertan in his hind end and the other "sickle" stars above Regulus (η Leo, Algieba, Adhafera, Ras Elased Borealis, Ras Elased Australis). I tried to find the galaxies below his belly but to no avail.

Getting late and fingers freezing, I called it a night. Hot chocolate, here I come!

Good Grief!
Observing in Less than Stellar Conditions

While enjoying my morning coffee on January 12, I read two articles in the February 2023 edition of Astronomy magazine – one by Bob Berman on page 12 made me chuckle and the second by Stephen James O’Meara on page 52 elicited an “ah-ha, so that’s what I saw!”

The curse of continuous cloudy skies disappeared on the previous evening, perhaps fleetingly, but nonetheless it was a clear, cloudless night. With my list of Messier objects to observe and to sketch, I stood beside our 10” Meade SCT that Jerry generously set up for me to view Cygnus’ brightest stars shining over western rooftops, Jupiter shining brightly in the south, and the Winter Circle with Mars and the Pleaides clearly visible in the east. At my disposal were 40 mm, 25 mm, 15 mm, and 10mm eyepieces and I was also going to try my Christmas gift - a Svbony 3mm - 8mm zoom eyepiece. My 10x42 image-stabilized binoculars were at the ready.

Bob Berman’s article explained how even backyard astronomers go through the five stages of grief when seeing is not the greatest. Seeing and transparency last evening were rated as average (and perceived as less than average); I experienced the stages just as he described. The session in question began at 6:45 PM AST and it wasn’t until I read his article that I could put it all into perspective.

Stage 1: Denial
Because I knew where to look, I found M31 using my 10x42 IS binoculars before beginning to look for M31, M32 and M110 with the Meade SCT. I used the go-to function and found the non-descript M31 smudge. There was no denying that M31’s characteristic features (bright centre, elliptical appearance) were being denied by the urban light dome, the sky conditions, the equipment used, or perhaps my watering eyes that required frequent drying. I could not make the stars in the FOV appear as pinpoints; they were fuzzy dots at best and mini donuts at worst throughout this session. I thought, “Okay, I know bad seeing is common so let’s look for another object. Maybe this was an exception.” Denial.

Stage 2: Anger
By changing an eyepiece or viewing the object again later in the session when sky conditions change, the possibility of observing the object in question usually improves – not this time. Again, the go-to function was used to “find” M110 (a small fuzzy). I was greatly disappointed in the lack of detail and the lack of definition of the stars, despite several attempts at focusing. Forget about finding M32 in that fuzzy non-entity. Andromeda, et.al., was a bust! The failure to observe these objects in the detail I wanted caused a bit of upset, anger to say the least. Adding to this, my headlamp’s battery died (special size of battery I didn’t have in stock), and I discovered my SQM’s battery was also dead. Bah, humbug.

Stage 3: Bargaining
In his article, Bob Berman stated, “You turn to the next stage: bargaining! Okay, but with whom?” A really good question given the sky gods seemingly weren’t cooperating so no sense appealing to them. I didn’t want to feel like I hadn’t tried, and Jerry was trying to help diagnose why I couldn’t “see” things. The decision was to bargain with myself. Bargain with myself? Who else was there? Try different targets, try different eyepieces, and keep my dry-eye syndrome at bay. My bargain was that if I succeeded in observing and sketching one target, I would go indoors to enjoy a hot chocolate.

Stage 4: Depression
How does one win a bargain with oneself? First, get gloves to keep fingers warmer (it was windless but -10 ̊ Celsius). Second, look for something the conditions would allow observing. Jupiter and its moons maybe? I started with the 40 mm eyepiece, then used the 25mm; Jerry could see the planet’s striping with both eyepieces albeit variable in moments of good seeing whereas it totally escaped me. This is the point where I considered giving up. What was the point in staying outside? Couldn’t see anything. Nothing worked. Bah, humbug.

I chuckled the next morning when reading Berman’s words: “...you suddenly realize what astronomers have known for 413 years: Wiggly, depression-inducing seeing is so widespread, you have no choice in the matter. A smile creeps across your face, the expression common to observers through the centuries. Finally you know its name and cause.”

Stage 5: Acceptance
Ahh, acceptance.... and the relative calm that ensues. It is what it is. Accept that conditions are poor and just play – and that’s just what I did. I couldn’t get Jupiter’s moons completely focused but at least this time they were just fuzzies and not donuts – Io on one side with Europa, Ganymede and Callisto on the other. I tried my 10mm eyepiece after failure to see Jupiter’s stripes with the 40mm and 25 mm. After staring through the eyepiece for several seconds, I was able to vaguely discern the stripes in variable moments of good seeing and they were almost perfectly aligned with the line of the Galilean moons. Success? Maybe.

Having experienced this “success”, I slewed to view the Pleaides, saw Mars as a small red featureless spot centred in my FOV, and then turned my scope to Orion’s M42. I sketched what I saw, assuming it was M42 and other stars and nebula in close proximity.

 

© Astronomy (February 2023, p5)

Now, let’s come back to my morning coffee and reading the February 2023 edition of Astronomy. Stephen James O’Meara, in his article entitled “The Theta Orionis challenge”, challenged us to split Theta1 Orionis and Theta2 Orionis without optical aids. It’s an interesting read but what especially caught my attention was the photo in his article. It was the mirror image of what I saw in my scope and what I had sketched! 

Ah-ha, so that’s what I saw! Four stars with one looking elongated (that I initially attributed to the frustrations experienced earlier), 3 bright-ish stars in a line with a fourth less bright forming an equilateral triangle with the two further out, and two stars (one above and one below the quadrilateral). The nebula surrounding it was heart shaped with the quadrilateral side more nebulous than the part covering the first star. 

Success!
What I learned from this session is that we as astronomers eventually do succeed when we keep going out into the dark and cold, despite all the grief it gives us while out there. We go back night after night (skies allowing) to observe that special object, to perchance sketch its details or to capture it digitally. It’s a process, one we go through alone or with like-minded others – and there’s always acceptance (at some level) of what we see and how well we see it. Don’t we all go through these stages at some point in our observing careers and doesn’t the memory of it stay with us – success or not?

General Session - October 28, 2022 (Sleepover)

Planets: Jupiter + 4 Galilean Moons, Saturn
Stars: Albireo (β2 Cygni, β1 Cygni)

Location: Home
Date: 2022-10-28

Time: 7:15 PM - 8:30 PM ADT
Equipment: Visual, Binoculars, Evostar 80ED
Eyepieces: Zhumell 4mm, Antares 15mm Plössl , Tele Vue 40mm Plössl 
Magnification: x150, x40, x15
Temperature: 5° C 
SQM: 19.17

Our youngest grandson was here for a sleepover so we set up the telescope to view a few things - Saturn, Jupiter and its moons, and whatever else we could interest him in. Given the temperature was a bit cool, interest was soon lost.

Jupiter
Time: 7:27 PM
Equipment: Telescope
Eyepiece: 40mm
We did see Jupiter and its 4 Galilean Moons; however, we could not make out the Great Red Spot (GRS). Io and Europa were on one side with Ganymede and Callisto on the other.

Saturn (in Capricornus)
Time: 7:45 PM
Equipment: Telescope
Eyepiece: 4mm
We observed Saturn and its rings which were seen as separate from the planet; there appeared to be a 'line shadow' on the planet caused by the rings. One moon was visible; guessing it was Dione.

Abireo (β Cygni)
Time: 8:22 PM
Equipment: Telescope
Eyepiece: all 3
I used the 40 first. The 15mm showed the separation of Albireo into β1 Cygni (yellow-white in appearance and larger) and β2 Cygni (smaller and blue). They were oriented in an up-down perpendicular line with β2 Cygni above β1 Cygni.

Jupiter (in Pisces) (4 observations)
I decided to try different eyepieces and my two Barlows to see what the difference was in the view and in focusing.

Observation 1:
Time: 10:16 PM
Equipment: Evostar 80ED
Eyepiece: Antares 15mm
Magnification: x40
Jupiter and all 4 of its moons were visible. Callisto appeared closest in alignment to the planet and was located at approximately 11 o'clock. 

Observation 2:
Time: 10:27 PM
Equipment: Evostar 80ED, x2 Barlow
Eyepiece: Antares 15mm
Magnification: x80
Jupiter and all 4 of its moons were visible. Jupiter's dark stripes appeared as 3 dark bands that were horizontal in the eyepiece.  

   

Observation 3:
Time: 10:35 PM
Equipment: Evostar 80ED + x3 Barlow
Eyepiece: Antares 15mm
Magnification: x120
This was difficult to focus. With the narrower FOV, only 3 of its closest moons were visible. The bands seemed slightly titled towards the horizon. 

Observation 4:
Time: 10:41 PM
Equipment: Evostar 80ED
Eyepiece: 9.7mm
Magnification: x62
As part of the eyepiece experiment with Jupiter, I put in the 9.7mm eyepiece. In doing so, the planet could be seen but the moons were not visible. There were also three bright stars in the same FOV. With SkySafariPro, I was able to identify and learn a bit about them. I was quite excited to discover the two set of double stars!

  • HD 965 - Double star, magnitude +8.56 & +12.30. 1476 ly from our solar system. Secondary appears 0.2 arcseconds/90 AU away from its primary.
  • HD 1050 - Double star, magnitude +8.14 & +11.81. 621 ly from our solar system. Secondary appears 6.9 arcseconds/1314 AU away from its primary.
  • HD 983 - Magnitude +8.96 star. 1125 ly from our solar system. This was very faint compared to the other two.

Saturn
Time: 10:48 PM
Equipment: Evostar 80ED
Eyepiece: Meade 9.7mm
Magnification: x62
The upper part of Saturn was tilted towards us. The South Pole just peaked out from below the rings. Five of its moons were seen and identified - Dione, Enceladus, Dione, Tethys, and Rhea.

M31 / Andromeda Galaxy

Time: 11:17 PM
S&T Chart Reference: 3, 72

Equipment: Evostar 80ED
Eyepiece: 40mm, 25mm, 15mm with x2 Barlow
Magnification: x15, x24, x80
I attempted to use the go-to to get to Andromeda but that didn't work so well. Consequently, I went to Mirach instead then slewed upwards - found! The 25mm eyepiece gave the galaxy a bit more form, i.e., you could discern the bright/dense core and its elliptical shape. When I used the 15mm with x2 Barlow, the galaxy became a larger grey fuzzy and the elliptical shape could not be seen.

Jupiter & Double Stars in Pisces
Time: 11:25 PM
Equipment: Evostar 80ED
Eyepiece: 2" 12mm with 92° FOV
Magnification: x50
Another part of the eyepiece experiment while viewing Jupiter. In doing so, the planet and is quite small but four bright-ish moons appeared. The three bright stars appeared again in the same FOV - HD 983, HD 1050 and HD 965. The bands on Jupiter were much clearer than in previous eyepieces.

M13
Time: 11:40 PM
Equipment: Evostar 80ED
Eyepiece: 2" 12mm with 92° FOV, 9.7
Magnification: x50, x62
I decided to have a quick view of M13 with two of the eyepieces. NOTE: unfortunately, my observing notes did not provide explanations as to how it looked.

I used Altair in Aquila and Vega in Lyra to locate the Coathanger. It was very faint but I did find thew 10-star asterism starting at Altair and heading towards Vega.

M31 / Andromeda Galaxy
Time: 8:00 PM
Equipment: Binoculars
S&T Chart: 3
I used the large "V" in Cassiopeia that points to a bright star at FOV 6 o'clock. I then had one more move southward to find the Galaxy. I then proceeded with SkySafariPro to identify some of the star field near it. 
 
M31 and its Star Field

Ophiuchus, M10, M12, Serpens Caput, Serpens Cauda
Time: 8:39 PMM36
Equipment: Visual, Binoculars
S&T Chart: 56
Ophiuchus was well above the horizon. The arc of stars at its base was unmistakable and made it easy to identify the snake's upper body and head (Serpens Caput) and its lower boy and tail (Serpens Cauda). Both very easily seen and well defined. With the central star of the arc (ζ Ophi) at 6 o'clock in my FOV, I went up 1.5 FOVs to find the faint fuzzy M10. The faint fuzzy M12 was 1 FOV to the right.

Around 9:15 PM, the skies was becoming a little murky. Consequently, the Dipper and Teapot disappeared from the sky.

Jupiter (in Cetus)
Time: 10:08 PM
Equipment:  Binoculars

Saw its location visually before viewing it with binoculars. The 4 moons were visible and they were in a curve formation, all on one side.

 

Saturn (in Capricornus)
Time: 10:23 PM
Equipment: Visual, Binoculars

Saw its location visually before viewing it with binoculars. There were two bright objects also visible; I think they were two of its moons - Dione and Rhea. 

Rasalgethi (Alpha Herculis A / α Her A in Hercules)
Time: 11:34 PM
Equipment: Binoculars
S&T Chart: 54

Rasalgethi is a visual binary, and on this night I could make them out! Both components seen appeared to be white and of equal brightness; one was larger than the other. There were other bright stars in the vicinity but I could not identify what they were.

Aldebaran, Hyades/Melotte 25, M45/The Pleaides
Time: 11:45 PM
Equipment: Visual, Binoculars
S&T Chart: 15
Once Aldebaran was identified, it was easy to identify the Hyades - the V-shaped open cluster in the Taurus. The Pleaides were then located a distance away; although it could visually be located, it was better seen with averted vision. I also used the binoculars to view these beautiful open clusters. The nebulosity of the Pleaides always impresses!

Mars
Time: 11:56 PM
Equipment: Binoculars
S&T Chart: 15
When viewing the area above the Hyades in Taurus's horns, I had noticed a reddish orb. I went back for a closer look. Using SkySafariPro, I discovered it was Mars!

Capella, Leaping Minnow, M36
Time: 11:58 PM
Equipment: Binoculars
S&T Chart: 12
After observing objects in and around Taurus, I then noticed Capella in Auriga. One of my favourite asterisms, the Leaping Minnow, is found in the area above and between β Elnath and ι Aur. Seven stars comprise the Minnow, including 14 Aur, 16 Aur, 17 Aur, 18 Aur, and 19 Aur. With just a slight adjustment of the binoculars, I was easily able to view the small grey fuzzy M36.

The skies really deteriorated at midnight. This ended the observing session for me (and the time-lapse for Jerry).

I can always easily find this in Scutum with binoculars - just look for the two stars at the top of the Scutum Star Cloud then look for the "backwards" golf club. With the telescope, I slewed SE from β Sct where the cluster appears. It had one bright focal point but with averted vision there was a hint of many stars in the nebulosity.

Cygnus was quite high in the sky at this time. Visually, I could see the Nebulosity of the Milky Way. Used the go-to to find Sadr (γ Cygni) then slewed S-SW to find the cluster. Took a while through a 25mm then the 15mm eyepiece to locate. Once located, I switched to the 2" eyepiece.

It's a very open cluster with very few stars. There was a rectangle of stars in the SW and a Dipper bucket-like set of 4 stars NE of it. Not sure if it was the transparency or whether there was in fact a faint star field in behind the cluster (Milky Way?).

Cygnus was high in the skies and well above the trees and our house. Used the go-to to get to Deneb from M29 (just viewed). From there, I slewed E-NE using my 25mm eyepiece. Once M39 was found and centred, I switched to the 12mm eyepiece for more detail. The centre stars seemed to form a semi-circle of brightness; otherwise, not many stars appear in this cluster. There was a hint of a very, very pale background of stars that may have been the Milky Way or due to a transparency challenge.

Cygnus was thankfully high in the sky is used Albireo as the point to star hop almost due south to Sagitta. 

What stood out was the rectangular shape in the lower FOV and the 2 lines of stars running parallel in this cluster. Many stars were visible in the cluster (I sketched only the brightest) and a hazier/brighter genre of pole strs was observed.

Using the 15mm eyepiece, M103 appeared as a very open cluster. The brightest stars were in an easily sketched arrangement. Unlike many clusters, there were no background faint stars, but there was a haziness surrounding the centre stars.

At Jerry's suggestion, I switched to the 2" eyepiece. The stars just popped out with the clarity this eyepiece afforded. I used this eyepiece for the sketch.

Jerry and I were in the backyard playing with this new scope. After alignment and finding other objects, I used the go-to feature to find M13 but of course it was way off! 

Using 2-eye vision through the dual-circle reticule finder scope, I slewed to where I thought M13 was located. Close. It was in the upper right quadrant of the 25mm eyepiece FOV. There was a bright star above it, a semi-circle of stars in the left FOV and a shallow triangle of stars with one star either being a double or just close enough to the cluster that it blurred.

Observation #2:

Quite a different view as short while later and with a different eyepiece!

Interesting to see the crescent of stars adjacent to the DSO that were seen earlier this evening under less magnification. The core could be seen; it was dense and at this magnification its perimeter was less dense.

No cloud, light breeze. Dew had already set in but hand warmers were applied to the scope and finder scope. Mosquitos to start the evening. Jackets not required for much of the evening. This was a session to hopefully overcome the alignment challenges experienced at Kejimkujik the weekend before (don't ask). Success with North level alignment, although it did require some minor slewing to centre the stars before saying 'yes, that's it'. I also had a new dual-circle reticule finder scope with which I practised 2-eye vision (just as Blair suggested years ago that I try).

The goals I set for this evening were to hopefully view some Messier and/or some of the DSOs in the now defunct constellation Taurus Poniatovii ("Poniatowski's Bull") - thanks, Dave, for showing me the Brian Ventrudo article in Sky & Telescope (A Visit to Taurus Poniatovii). Success on both counts - not overwhelming success, but success nonetheless. I stayed out until 1:30 AM before taking down and after attempting to find a few other items in Taurus Poniatovii without success.  I would have been out a lot longer had we not been heading to the Valley tomorrow for a day at the beach.

Time: 10:30 PM ADT
Equipment: Telescope + 25.0 mm and 15 mm eyepieces

After aligning the scope, I attempted to find Mizar and Alcor using the 25 mm eyepiece. It slewed to the correct direction but Mizar was not in the FOV. I had to use the finder scope to get it to the correct place. Found! 

I then switched out the eyepiece for 15 mm and used that view to sketch what was seen. I could actually see Mizar's ζ1 Ursa Majoris and ζ2 Ursa Majoris separated, one slightly larger and consequently seemingly brighter than the other. Interesting that the jury is still out as to whether these are a visual double or whether they are in fact gravitationally bound.

Time: 11:18 PM ADT
Equipment: Telescope + 25.0 mm eyepiece

I had the scope go to Cebalrai (β Ophi) and then slewed to find this open cluster that spells "HI". It literally filled the FOV with so many stars. What I sketched were the brightest of the stars I could see. It wasn't until I had finished the sketch and looked at what was on paper that I realized the stars did in fact spell "hi". Very Cool!

History of Taurus Poniatovii:
In 1777, Marcin Poczobutt, director of the royal observatory at Vilna (Today's Vilnius, in Lithuania), named it after Stanislaw August Poniatowski, King of Plane and Grand Duke of Lithuania from 1764 to 1795. Poczobutt catalogued 16 stars and Jean Fortin included them in 1778 in his Atlas céleste de Flamséed as Taureau Royal de Poniatowski. John Alert Bode added many fainter stars to the asterism in his 1801 Uranographia. It fell into disuse in the later 19th Century. The name remains, though, to describe what currently is an asterism entirely within Ophiuchus.

M13 (Hercules Globular Cluster)
Time: 11:51 PM - 12:07 AM ADT
Equipment: Telescope + 25.0 mm and 15 mm eyepieces
S&T Chart Reference: 52

Using the 2-eyed vision through the finder scope, I had to slew to where I thought M13 was located a little below the line between η Herculis and ζ Herculis. Close. It was in the upper right quadrant of my 25 mm eyepiece FOV.  There was a bright star above it, a semi-circle of stars in the left FOV, and a triangle of stars to its upper right where one star was either a double or just had an optical double.

After sketching the 25 mm view, I inserted my 9.7 eyepiece for a completely different view. I could see the core was quite dense and there was a lighter area around its perimeter. There was a crescent of stars adjacent to it that I could not identify and a bright star in the upper right quadrant (maybe HD 150998).

Scutum was high in the SE sky so easily located tonight. 
M11 is one of my favourite clusters. It is easy to locate visually and with binoculars and can be easily identified in a time-lapse photograph. I consider it the golf ball that is next to the golf club.

I was learning to slew this new-to-me telescope. I slewed SE from β Sct where the cluster appears. It had one bright focal point but with averted vision there was a hint of many stars in the nebulosity. There were 2 stars (SAO 142703 & V369 Sct) that were close to the cluster and appeared to have some nebulosity as well.

M14 appeared as a faint fuzzy half way and east of the line between Celabrai and Sabik. I could not make out any individual stars but it was equally 'dense' within the cluster.

There was an arc (like the one in Scorpius that includes Graffias). It was to the NW along with a much brighter star in the west. Two there stars appeared in the FOV as well.

M12 was found by slewing from M10, eastwards and up slightly. What I found interesting when using the 5 mm eyepiece was the bright two stars in the lower right quadrant of the cluster's nebulosity. I couldn't make out any other stars in the cluster.

There was an arc of stars to the east of M12 and 2 others at a diagonal (NE-SW) west of M12. Several other very faint stars were visible with averted vision but there were too many to sketch.

Once again, I looked for the double stars Mizar and Alcor to also find their 3rd smaller and dimmer companion HD 116798. The eyepiece also allowed for a splitting of Mizar into  Mizar A and Mizar B.  Very happy about that.

There was another star almost due west of Mizar - GAIA 1563592744010133120 ("GAIA" in the sketch).

Albireo β1 was a very bright yellow and was quite close to the blue Albireo β2.

I also noticed 3 stars south of Albireo and one slightly above at 2 o'clock that formed an arc. There was also a very bright one at 10 o'clock.

Time: 11:37 PM ADT
Equipment: Telescope with star diagonal
Eyepiece: Antares Plössl 15mm
Magnification: x40

Learning to slew the telescope to the object. I have viewed this object numerous times with binoculars so knew generally where to look - 1/3 of the way up along the line from Sabik to κ Phiuchus. Ophiuchus remained high in the sky all session. M10 is a very faint roundish object; could not see any individual or bright grouping of stars within the cluster.

Also refer to. Messier Catalogue - M010 (NGC 6405) - July 22, 2022.

 

   

M12 / NGC 6118
Time: 11:37 PM ADT
Equipment: Telescope with star diagonal
Eyepiece: Antares Plössl 15mm & 25 mm
Magnification: x40 & x24

M12 was found by slewing from M10, eastwards and up slightly. There were two bright stars in the lower right quadrant but could not make out any there stars in the cluster.

For more details, go to Messier Catalogue - M012 (NGC 6218) - July 22, 2022

 

   

M14 / NGC 6402
Time: 12:02 AM ADT
Equipment: Telescope with star diagonal
Eyepiece: Antares Plössl 15mm
Magnification: x40

M14 appeared as a faint fuzzy half way and east of the line between Celabrai and Sabik in Ophiuchus. I could not make out any individual stars but it was equally dense within the cluster. 

For more details, refer to Messier Catalogue - M014 (NGC 6402) - July 23, 2022.

 

   

M11 / NGC 6705 / Wild Duck Cluster
Time: 12:35 AM ADT
Equipment: Telescope with star diagonal and 9.7mm eyepiece
Magnification: x62
S&T Chart: 67
Scutum was high in the sky for most of this observing session.  M11 was found by slewing from β Scuti. The cluster appeared to have one bright focal point but with averted vision there was a hint of many stars in the nebulosity. 

Also refer to Messier Catalogue - M011 (NGC 6705 / Wild Duck Cluster) - July 23, 2022

   

Arcturus
Time: 1:35 AM - 1:45 AM ADT
Equipment: Visual + Binoculars 10x42 IS
As is my habit, I look out my window every evening after lights out. In the west was a bright seemingly twinkling reddish object. Was it a plane or a star? I stared at for a good 30 seconds to determine if it appeared to be getting closer or if it was it blinking, then gave up - got out the binoculars in the bag at my feet.

Yup. A star. A bright one with a group of stars in the same FOV completing the formation of an upside-down "U". But what star was in this star field? Now to SkySafariPro for some assistance. Arcturus! Positively identified with the U-shaped star field. Arcturus was very bright and large compared to the dimmer, smaller stars of the star field.

Identified the quite bright Aristarchus with its central peak in Oceanus Procellarum. Also noted the adjacent and much darker Herodotus. They appeared to be on a dark plateau and there was an even darker mountain range. I then slewed to the crater Plato which was easy to identify because of its roundness, white well-lit rim and the large dark-floor on the north shore of Mare Imbrium. I then slewed to Mare Crisium and discovered this small, bright white circular crater - Proclus. You could also see the well-lit rime on the NE edge of Palus Somni.

Warm, no wind or clouds. Mosquitos!
 

We had our youngest granddaughter tonight for the second night of a 2-night sleepover. She and I slept in our tent in the back yard. I showed her the Moon through the newly acquired scope and she was wowed.

She looked through the finder scope most times while I was viewing it through the eyepiece. Because I didn't have any tracking, it meant having to determine if the Moon could still be seen in the FOV.

 

One exciting rediscovery for me was the Aristarchus Plateau that was just above the line of the terminator. Around 7:30-8:00 PM, the rims of the two craters (bright-walled, central peaked Aristarchus and flat, dark-floored Herodotus) were very bright and that was what captured my attention at first. I initially thought they were Kepler and Encke until I used Sinus Iridum and Mare Imbrium to get the correct orientation of the Moon and therefore correctly determine what it was I was looking at. The curved Vallis Schröteri with its little kink halfway along the bend joined to Herodotus was seen with a pin-thin shadow on its floor. I could not discern the cobra head at the valley terminus near Herodotus.
 
I had seen the Plateau, associated craters, and the adjacent Montes Agricola before when it was well away from the terminus. Refer to IWLOP #122 - Aristarchus Plateau and Plateau Schröteri for details of my first observation of this interesting area.
The easily identified Gassendi, its attached Crater A, its missing wall adjacent to Mare Humorum were another fun rediscovery.
 
Going further south along the terminus at 8:00 PM, I also thought I was seeing the crater Bailey but at 10:30 PM I realized it was Schickard with its floor in the terminus darkness but a small part of its western wall illuminated. In a curved line along the terminus south of Schickard, I identified Phocylides, Segner, Zucchius, Bettinus, and Kircher with the elongated Schiller above Phocylides also easily identified.
 
Tycho, surrounded by what I refer to as its flower petals, was easily seen as was its huge ejecta field across the Moon. I tried to explain this to our granddaughter but it was lost on her. Although highly illuminated at this point, I was able to locate Maginus (because of its shape and few craters on the western wall) plus Clavius (with the large craters on its floor with Porter in its NE wall).
 
As the night got darker, she was shown stars by Grandpa Jerry and noted Vega (the first star we saw), the Big Dipper that she could see before us with her young eyes, Deneb, Altair, and Arcturus. He explained how the middle handle star in the Dipper was a double. When finished with the lunar searches, I turned my attention to the Big Dipper, specifically the double star (Mizar / Alcor) he mentioned. I was able to show it to her in the EVOSTAR; not sure if she was impressed or not; hard to tell. 
 
Didn’t think she would have an interest in the night skies but she had been learning some astronomy at school. She certainly asked questions - how far the moon is, whether our sun will explode and eat Earth and when, how far were the stars she saw, etc. A great evening but an early end to observing for me and a late evening for the little astronomer around 10:45 PM.

General Session - June 28-29, 2022 (Dyer's Top "10") (5th Annual Big Muise Island Star Party)

Day 1 (June 27): It's another weekend with the Chapmans. We arrived at the Park on a warm sunny day with light to moderate winds across Kejimkujik Lake - until we turned towards our site on Big Muise Island. The wind had certainly picked up and continued to increase over the afternoon and evening. Rain!! Most of the afternoon into the evening, heavy bouts throughout the night. Observing out of the question!

Day 2 (June 28): Gentle rain for half the morning. Then the wind died, skies cleared and a beautiful day ahead. Yes, it was an amazing night under the stars! Jerry and I sat on the beach and watched as the golden glow of the sun in the west and the changing purple-pink in the east. The sound of small waves on the shore and the last sounds of the song birds were enjoyed. Did I mention mosquitos?

We enjoyed one of the darkest nights I've ever experienced there. New Moon, clear sky, no breeze (perfect for mosquitos, not us), and no haze. SQM was higher than any I hope to obtain at home. With a clear horizon lower than ever seen in the past few years, Dave discovered Mankent in Centauri whereas I found objects in the lower part of Scorpius never before viewed (or so I thought), not to mention seeing all the stars in the tail.
 
In the recent RASC-produced SkyNews (July/August 2022) was Alan Dyer’s top 10 list of summer Milky Way targets that we decided to try finding. Because Dave needed to select 15 objects to make an observing list in SkySafari, the list was renamed “Alan Dyer’s 15 top 10 Targets in the Summer Milky Way.” These objects were found between my searches for the familiar, for those not seen for a long time, and for those new to me.
Barred Owl © Jerry Black
Dave referred to distractions that seemingly prolonged our observing session. One was my so-called "little binoculars" - 2.1 x 42, FOV 26º. Dave, Jerry and I had fun sharing them throughout the session and we chuckled with each handover because eyepiece adjustments had to be made each time. 
 
Mother Nature also gave us reason to pause throughout the night. We saw an owl, perhaps the Barred Owl we saw earlier, swoop silently to the reeds on our shore, hover, then silently fly to the opposite island. Fireflies in the shrubbery were a lighting surprise. Peepers and bullfrogs croaked occasionally. The anticipated soulful call of loons interrupted the quiet of the Kejimkujik night at least 3 times, beginning at sunset and continuing well into the night.
All in all, it was a highly successful and memorable night under the stars with great company!

Stars of Boötes
Time: 9:44 PM
Equipment: Visual + Binoculars 
S&T Chart Reference: 42, 44, 53, 55


Arcturus was the first star I noticed naked eye in the darkening skies. Wanting to locate and identify the stars below Arcturus, I used the binoculars hoping to find them. Success! Muphrid/η Boo, τ Boo, υ Boo, ζ Boo and 31 Boo were found.

Observations:
1. 
The distance from Arcturus to ζ Boo was about x1.5 the distance of that between Arcturus and Muphrid.
2. 31 Boo was slightly fainter than ζ Boo.
3. τ Boo and υ Boo appeared similar in magnitude and were dimmer than Muphrid.

Research Notes:
1. Arcturus is mag -0.05 
2. ζ Boo is a triple star - physical binary (mag 4.5 & 4.6) plus optical companion (mag 10.9).
3. 31 Boo is mag 4.86.
4. τ Boo was mag 4.5, υ Boo was mag 4.06, and Muphrid was mag 2.68.

 

 

 

  

Scorpius
Time: 10:00 PM
Equipment: Visual + Binoculars 
S&T Chart Reference: 56, 58, J

First thing noticed about the constellation was that it was ALL above the horizon! Antares was a definite red and what amazed me was the ω1 Sco and ω2 Sco location was visible naked eye. Binoculars showed the separation and their proximity at 7 o'clock to Graffias. I attempted to find M4 in this area but was not successful.

   

Teapot, M7, M22, M28 + Dyer's #2 
Time: 10:00 PM - 11:00 PM
Equipment: Visual + Binoculars 
S&T Chart Reference: 67, 69

The Teapot was on the opposite side of the Milky Way from Scorpius and very easily identified as were numerous Messier objects in its vicinity.

  • M7 (Ptolemy's Cluster), west of Kaus Australis, shone brightly just above the horizon. Another of my favourite open clusters that almost fills my FOV. It reflected so beautifully on the surface of the mirror-like Lake.

  • M22/NGC 6656 was readily found east of Kaus Borealis (Teapot lid star). I went east from the star to find what looks like a group of stars forming a "Y" and just past that was the small round fuzzy.

  • M28/NGC 6626 was seen as a small fuzzy adjacent to Kaus Borealis.

Dyer's #2

  • M8 (Lagoon Nebula), above the spout, showed its characteristic line of stars in a nebulous oval-shaped border. The stars were particularly bright this evening.

  • M20 (Trifid Nebula) was found above M8, and appeared as a small round, centrally bright object. Same FOV as M8.

  • M21/NGC 6531 formed the 3rd side of a triangle with M8 and M20. Not as dense looking as the Trifid but a beautiful small open cluster nonetheless.

M17, M18, M24 + Dyer's Top 10, #3
Time: 10:00 PM - 11:00 PM
Equipment: Visual + Binoculars 
S&T Chart Reference: 67, 69

M24 (Small Sagittarius Star Cloud) was easily found and viewed with binoculars. However, I did not identify Barnard 92 nor did I search for M25 as suggested by Alan Dyer.

In addition, I used the length of Kaus Australis to Kaus Media and went up x3 that length in binoculars to locate the small open cluster M18/NGC 6613 and M17 (Omega Nebula) above it with its larger size and nebulosity.

Ophiuchus, M10/NGC 6254, M12/6218 +
Dyer's #1 & #5

Time: 11:00 PM
Equipment: Visual + Binoculars 
S&T Chart Reference: 56, 58, J

Ophiuchus is never hard to find above Scorpius and adjacent to Hercules. Its main stars were easily located from Rasalhague down to Sabik. I knew that two Messier objects were in the interior lower 1/3 of the constellation. I visually located Marfik/λ Oph, put my binoculars up and looked east of there to find both M10 and M12 well within my FOV. Both appeared as small greyish fuzzy objects.

Dyer's #1
We initially looked for the Dark Horse Nebula because the Pipe Nebula  and the large bowl of the Pipe - Barnard 78 - were part of it. In essence, the rear end of the horse comprises the Pipe Nebula. Area surrounding the nebula was quite bright by comparison.  Also learned following this trip that the nebula also has the designation of LDN 1773 - (Lynds Catalog of Dark Nebulae).

Dyer's #5
With Alya of Serpens at 9 o'clock in my binocular FOV, I found IC 4756 just a little above and to the right of the centre. By moving my binoculars just 1/2 FOV further west, I had it and NGC 6633 in view. Both beautiful and big! Stars dispersed in both clusters with the NGC a little smaller in size, a bit more compact, and perhaps a bit brighter as well.

 

 

 

 

M12 on the right next to 30 Oph; M10 in centre & left of Marfik/λ Oph

Scorpius + NGC 6231 + Collinder 316 - New to me!
Time: 11:40 PM
Equipment: Visual + Binoculars 
S&T Chart Reference: 58, J

Using binoculars, I noticed 3 very bright stars I thought were below Scorpius. Turns out they were actually in the tail - ζ1 Sco, ζ2 Sco and HR 6266.

In the same FOV and above them was a beautiful little cluster with quite a bright core that I identified as NGC 6231; not really sure if I could make out any individual stars.

Looking above NGC 6231 was a scattering of stars with about 9 bright stars among thousands less bright distributed throughout a broad nebulosity - Collinder 316 - and it was quite a large open cluster! Come to find out when I returned home that NGC 6231 was observed in San Pedro de Atacama (2018) when shown the "false comet" that was formed by it and Trumpler 24.  

As long as these features remained above the horizon, I kept returning to look at them. Beautiful. An 'oh wow' moment on the beach that I wanted to etch into memory.

Keystone of Hercules + M13 (Hercules Globular Cluster)
Time: 11:45 PM
Equipment: Visual + Binoculars 
S&T Chart Reference: 56, 58, J

With such a clear sky, I sought the Keystone of Hercules to locate M13 (Hercules Globular Cluster). Looked for the Big Dipper, moved easterly to Corona Borealis then further east for the Keystone quite high in the sky. With binoculars, I looked 2/3 of the way north from ζ Herculis to η Herculis. Success! There was the familiar small grey fuzzy.

Scutum Star Cloud (Dyer's #4)
Time: 12:00 AM
Equipment: Visual + Binoculars 
S&T Chart Reference: 67, 69

Scutum Star Cloud is one of my favourite sites to find as it contains M11 (Wild Duck Cluster). Always able to find this object because of its rather square-ish nebulous appearance with a bright object in each of the uppermost 2 "corners" (M11 and β Sct). In my binocs, M11 looks like a small, bright, round fuzzy golf ball beside the golf club formed by stars in the star cloud.

M55 / NGC 6809 (Summer Rose Star)
Time: 12:10 AM
Equipment: Binoculars 
S&T Chart Reference: 66, 68

M55 is located between the Teapot in Sagittarius and Capricornus. I used the Teapot as the start point to find it, placing Nunki at about 2 o'clock in the FOV. I then moved down 1 FOV where the globular cluster was just off-centre.

It can also be found by going from Ascella to τ Sgr in the lower handle of the Teapot then following the arch of stars from there - ψ Sgr to ξ Sgr to 52 Sgr. The cluster can then be seen "below" 52 Sgr.

 

 

Delphinus, Equuleus, Sagitta + Dyer's #7 
Time: 12:38 AM
Equipment: Binoculars 
S&T Chart Reference: 62, 64, 75
SQM: 22.20 (the highest ever at this site to my recollection)
Temperature 15º C

Dyer's #7, the Coathanger / Collinder 399 / Brocchi's Cluster, is one of my favourite asterisms to view in the night skies. Easily found 1/3-1/2 of the line from Albireo (in Cygnus) and Altair (in Aquila). In our Northern Hemisphere, the hanger is upside-down and at an angle. All 10 stars in this asterism were easily seen and identified.

While in the Coathanger neighbourhood, I visually located three familiar friends:

  • Sagitta is a very small 4-star constellation. On this night, it took a few seconds to locate this relatively faint star formation near the Coathanger.
  • Delphinus is below Sagitta and near Altair. Its 5-star formation was easily found.
  • Equuleus is a 3-star constellation first pointed out to me by a friend at a Nova East Star Party. It is located a bit below and to the east of Delphinus.

 

 

 

 

 

M53 / NGC 5024
Time: 12:49 AM
Equipment: Binoculars 
S&T Chart Reference: 62, 64, 75

I used Arcturus as the start point, then travelled down to Muphrid. From there, I went 1.5 FOVs and M53 was pretty much centred in my view above Diadem (α Comae Berenices). It was small, dense, faint grey, and circular.

M3 / NGC 5272
Time: 1:11 AM
Equipment: Binoculars 
S&T Chart Reference:
44

I used Arcturus at the 8 o'clock position in my FOV then moved up 1 FOV. M3 was then seen. There appeared to be distinct formations formed by stars adjacent to M3 that I attempted to identify. Not sure if these are correct. 

  • 3 stars in a triangular formation east of M3 - tentatively identified as HD119391, SAO 82955 and TYC 2004-1463-1.
  • 4 stars in an arc-like formation east of the triangle - tentatively identified as HD120049, HD119686, HD119477 and SAO 82958
  • 2 stars formed a triangle with the Messier object facing west - tentatively identified as HD199748 and HR5145

 

 

     

Dyer's #8, #9 & #10 
Time: 1:45 AM
Equipment: Binoculars 

Certainly, some objects on his list were new to me and did provide fun and a challenge to find and observe, such as nebulas with 10x42 binocs. It was around this time we heard the bullfrog for the first time and noticed fireflies in the shrubbery between us and the campsite.

Dyer's  #8 - New to me!
S&T Chart Reference: 62, 73
The Veil Nebula filled my FOV; the circular formation of the east and west arcs could be faintly discerned but details of the arcs' composition and density were not forthcoming. I had seen this object in segments though other RASC members' telescopes but this was first seeing it through binoculars. NGC 6940 was not viewed.

Dyer's  #9
S&T Chart Reference: 62, 73, H
The North America Nebula/NGC 7000/Caldwell 20 was a nebula that had alluded me until a couple of years ago. Located adjacent to Deneb, I had been searching for a "black" patch of sky instead of the illuminated patch of nebulosity with stars. The Gulf of Mexico with the Yucatan Peninsula are the formations I look for when seeking out this object. I did not note the Northern Coalsack that Alan Dyer mentioned in his article.

Dyer's #10 - New to me!
S&T Chart Reference: 62, 73, H
The Funnel Cloud Nebula / Le Gentil 3 was fun to find between Cygnus and Cepheus. It took a few moments to locate this dark preserving funnel-shaped object. It wasn't as dark as I had anticipated; it was dark but had a very pale nebulosity. The sky was certainly brighter along its borders. Can't wait to view it in larger binoculars or in one of my telescopes.

Time: 7:40 PM AST
Equipment: Binoculars
Dave Chapman pointed out the asterism. Three sets of double stars with supposedly a single star each for the tail and head. Very easily seen with the binoculars.

It includes Aurigae 14, 16 & HD 34257, 17 & IQ Aur, 18 & 19 and another star unidentified. It doesn't look like a minnow in the star maps but it sure does in binoculars! Can't miss it!

If looking in a telescope it is between IC410 and the Flaming Star Nebula / IC405.

   

Geminid Meteor Shower
Time: 7:00 PM - 9:00 PM AST
Equipment: Visual
The slight hazy skies eventually clouded over and gave us snow that needed the observing session. However, we did get to see 17 Geminids over the 2-hour time frame.

Jerry and I were in our back yard. He had set up his camera to capture some Messier objects, whereas I had set up the 10" Meade (with his help). According to Astrospheric, the skies were average Seeing and below average transparency. Bright stars were clearly visible but I did recognize that dimmer stars would be more challenging to see.

This evening's session had 2 purposes:
     1- To use my new acquired 20 mm illuminated reticule eyepiece, and
     2- To practise conducting what I refer to as the 6-star alignment but was actually a 2-star alignment plus 4-star calibration. The stars used for the alignment were Spica (in Virgo) and Dubhe (in Ursa Major). The calibration stars used (not in order they were used) were Mizar (in Ursa Major), Denebola (in Leo), Arcturus (in Boötes), and Alphecca (in Corona Borealis). It wanted to use Vega and we did let it slew to its location but we would have to move our house for it see it. Too funny.

After finding each of the 6 stars using the go-to feature of the telescope, I centred the object in the finder scope then went to the eyepiece to centre it using the lit reticule. What a difference it made with the object truly centred. Changing to an eyepiece with a higher smaller resolution would mean the object would remain in the FOV which would allow for sketching of the objects and the star field (perhaps at different magnifications). With each star being centred and confirmed, the ability of the scope to find have the wanted object in the FOV improved.

Castor
Time: 10:57 PM ADT
Instrument: 10" Meade SCT with 20 mm illuminated reticule
Magnification: x125
SQM: 19.48

Sketched with 20 mm illuminated reticule

 

This was an "Oh, Wow!" moment.

I had Castor centred in the illuminated reticule, turned off the light and noted the star appeared elongated, perhaps due to not being in focus. When focused, there it was - a double star! Oh, wow!

Two stars, one above the other, one brighter than the other, one larger than the other and extremely close to one another. I could also see two other stars in the FOV that otherwise was devoid of any other stars.

Using SkySafariPro, I was able to identify the two stars as YY Geminorum (also known as Castor C) and TYC2453-0454-1.

When I went back in the house later, I did some research on Castor. SkySafariPro had named both stars as Castor α Gem with no distinction other than different magnitudes. This piqued my curiosity. Come to find out that Castor is a 6-star system, all of which are spectroscopic binaries. Castor A and Castor B have magnitudes of 1.9 and 3.0 respectively and only 6 arc seconds apart. Castor C is an eclipsing binary with an apparent magnitude of 9.8; it is 73 arcseconds distant from the bright components.

All six stars are bound to each other by gravity and share a common motion through space. The components of each of the three binary systems orbit each other and the three binary pairs also circle around each other in a total of five orbits. Castor A and Castor B have a period of 445 years and Castor AB and Castor C complete an orbit every 14,000 years. Individual components have much shorter orbital periods: 9.2128 days for Castor Aa and Castor Ab, 2.9283 days for Castor Ba and Castor Bb, and only 0.814 days for Castor Ca and Castor Cb.

M105
Time: 11:257 PM ADT
Instrument: 10" Meade SCT with 20 mm, 15 mm, 12 mm with 90º FOV
Magnification: x125, x167, x208
SQM: 19.52

Using SkySafariPro, I located M105 halfway below the imaginary line joining Regulus to Chertan. I then used the go-to to slew to that area and saw after much staring in to grey space what was a very, very faint smudge that I centred in the finder scope. I then moved to the SCT and had to make minor adjustments to get the smudge centred in my newly acquired 20 mm lit reticule. No definitive shape other than potentially an oblong out of focus. It remained as an undefined grey smudge on a grey starless star field despite several attempts to see it using the 20 mm, 15 mm and 12 mm. I gave up for the evening, especially in light of the poor quality of the transparency. So disappointing.

Perhaps next time I should try one of the many filters I have to determine if one of them makes a difference in what is seen.

The Big Dipper was standing on its handle above the roofline of our house in the NE. This was my first observation of the double star in Ursa Major!

I used the telescope to find Dubhe from where I was observing M35 in Gemini. I then slewed to Megrez before going a little lower on the right. The pair become very evident in the FOV. 

The stars comprising the pleasingly close pair were:   
   * HD238107 - the brighter one of the pair (mag 9.65)
   * HD238108 - less bright (mag 10.10)

These 2 stars were amazingly bright against the "black background."

It's a very open but faint and diffuse cluster. I could see how it got its name while looking through the eyepiece (with a bit of imagination) but it did look more like a cross. I don't think my sketch captured the starfish appearance. To my eyes, it looked like a cross on its side. I had slewed northerly of M36 to find M38.

I had observed M38 almost 4 years ago at SCO - a night of discovery!

Having found M36 a few moments ago, I moved my binocs just a little towards the north (~ 1 FOV). M38 was very faint in the binoculars so tried the SCT - success! Still a bit faint and diffuse in the eyepiece but I could see 4 definitive bright stars. There rest of the star field was diffuse; perhaps because of the haziness closer to the horizon, the "cross" structure I had read about wasn't visible.

I was visually observing Messier objects and Jerry was imaging DSOs.

I slewed the scope "up" from Elnath in Auriga, just west of the line formed between Elnath and θ Auriga. I had used the same technique in a 2018 observation. M37 was seen as a very open cluster. Couldn't determine a pattern or shape other than the curve of stairs in the SE.

NOTE: I had observed M37 for the first time four years ago, and have looked at it with binoculars many times since.

Now that I knew M37 is an open cluster (not a globular one as I had assumed 4 nights before), I hoped to have a better chance of finding it just west of the line formed between Elnath and θ Auriga.

It was very loose with a bright central star and 5 other bright stars. The haziness near the horizon made for difficulty in seeing more stars of the cluster. I used my binoculars and after a few tries I found it! I drew it as I saw it. Jerry then used our SCT* to confirm it was what I saw.

 

* At this time, the SCT was not on motorized mount. We jokingly referred to it as the "push-to SCT."

I knew M36 was between M38 and M37. After locating M37, I slewed the telescope northerly and a little lower towards the horizon. The centre seemed to be filled with multitudes of dim stars. No one star really stood out as being the brightest in the cluster. Could see where some of the lines of stars were curved like a pinwheel's blade, although one may not guess that from my sketch.

I first viewed this Messier object almost 3 years ago.

Jerry and I were looking for Messier objects - me to visually observe (outside), him to image (mostly inside). Gemini held its high position above our trees to the W-SW.

Located Tejat then slewed northerly and lower towards the horizon just a little. It's a beautiful cluster with lots of stars. I began my sketch with the two bright central stars. There was a curved line of 5 stars to the east of them. Seven stars that went SW then 2 stars to the west looked like a hockey stick with a super huge blade. Didn’t notice nor look for the adjacent NGC 2158.

NOTE #1: I first viewed this cluster on May 5, 2018 at 10:10 PM at SCO with binoculars. It looked like a fuzzy circle when viewed with averted vision. I could detect 4 bright stars.

Jerry and I were again looking for Messier objects - me to visually observe, him to image.
Gemini was high above our trees as was most of Orion. Followed Castor's stars to his foot to find M35. many bright stars visible with too many to count in the diffuse background. Bright point south of it that made me wonder if it was NGC 2158 (or was is it 1 Geminorum?).

Tried 40 mm Plössl but the cluster was too small and faint so switched to the 25 mm Plössl.

I used the distance from Shedar to Caph, followed the line they formed up the same distance to find M52. Had fun trying to slew at an angle versus a vertical or horizontal line.

M52 is much smaller and fainter than the 3 Messier objects in Auriga. Looked almost rectangular in shape with the brighter stars on the north side.

Earlier this evening, the 3.1% Waxing Moon shone through the layers of sunset colours and Venus appeared at sunset as well. 

8:04 PM
Signs of the Milky Way were appearing at the tree line edge on our shore. Quite bright in that area. 

We watched the night skies as Arcturus, the Big Dipper's stars (including Alcor-Mizar), Ophiuchus, Serpens Cauda and Serpens Caput appeared. We followed the Big Dipper's pointer stars to Polaris in the Little Dipper; we definitely saw the 4 stars in its bucket but sure if the remaining 3 starts in the constellation were really seen or were just imagined.

8:13 PM
There is no wind to speak of and the lake is dead calm for another night. So unusual for this Lake to remain calm for so many days and nights in a row!

 

   

8:17 PM
Venus is very red when it was approximately 1° above the horizon, as it sank between the trees of an adjacent island. Beautiful!

In binoculars, M10 and M12 appeared as faint fuzzies in Ophiuchus. I used ζ Ophiuchus as the starting point to star hop up the constellation to find these two Messier Objects.

9:22 PM
Jerry asked how to find M10 and M12, and if there were stars in the globular clusters that you could see. I hadn't noticed before but I did take a closer look with the binoculars. I wasn't sure whether or not I could see a few pinpoints of light or not in each cluster.

View of Kejimkujik Lake from Campsite 14 - Antares and Venus rise above the islands

Jerry and I had paddled To Site 14 from Site 15 earlier today and said our good-byes to the Chapmans as they headed for home.

From the little beach of our site, we could hear the sounds of youngsters at the group campsite not too far away. 

7:52 PM
We could see Venus above the trees on an adjacent small island.  Antares in Scorpius could be seen about 10° away at the same declination; Dschubba and Graffias also easily seen. The lake was unusually dead calm for the third day in a row. Highly unusual.

 

8:19 PM
I was scanning the skies for objects I knew where to find. I was locating items but was not truly observing them.

  • From the Teapot in Sagittarius: M6, M7, M8, M20, M22
  • In Ophiuchus: M10, M12
  • In the Keystone of Hercules: M13
  • Big Dipper: all 7 stars visually; used my binoculars for Alcor-Mizar

8:55 PM
I located Scutum in the Scutum Star Cloud and identified the 4 corner stars - ß Scuti, α Scuti (Ionnina), γ Scuti and δ Scuti, ε Scuti was part way between ß and δ. Also found M11 - the small fuzzy "golf ball".

For some reason, we headed to bed early. However, while we slept, the time-lapse camera captured a meteor between the Big Dipper and Boötes - the brightest and longest we had ever seen. Jerry, along with 10 others, reported it to the American Meteor Society (AMS).  From these, the AMS was able to calculate the trajectory - https://fireball.amsmeteors.org/imo_view/event/2021/6384.

This was another weekend with the Chapmans at our annual Big Muise Island Star Party.

Grus (The Crane)
Time: 9:21 PM

Equipment: Visual
S&T Chart: 78, 79
This was the first time this constellation as seen. The line of stars coming out of the southern point of our island caught my attention, especially the triangle at the top and the smaller triangle near the trees. Could not find δ Gru but did find σ Gru. 

Pisces Austrinus
Time: 9:30 PM ADT

Equipment: Visual
S&T Chart: 76, 77, 79
Pisces Austrinus always catches my attention at the south end of our island, with α Fomalhaut always catching my attention first. I took a few minutes to locate the other 7 main stars in this fish. 

The Teapot, M6 (Butterfly Cluster), M7 (Ptolemy's Cluster), M8 (Lagoon Nebula), M20 (Trifid Nebula), M22
Time: 9:42 PM ADT

Equipment: Visual, Binoculars
S&T Chart: 67, 69
The Teapot was shining above the far end of the Lake so took this opportunity to find several of the Messier objects in its vicinity. Because it was high enough, I was able to find M7 (Ptolemy's cluster) - that beautiful open cluster of bright stars found near Kaus Australis. M6 (Butterfly Cluster) was found not too far from M7. Using an imaginary line going through the Teapot spout, I found M8 then M20 not too far away. Their familiar "binocular view" shape and star patterns made it easy to identify them. I used the star of the Teapot lid (Kaus Borealis) to go up at a 45° angle to find a Y-shaped group of stars then a little further out was the small fuzzy ball M22. Another successful session with the Teapot!

Corona Borealis, Keystone of Hercules, M13
Time: 9:53 PM ADT

Equipment: Visual, Binoculars
S&T Chart: 52, 53
Corona Borealis was quite high in the sky and all 7 of its stars readily identified. I used it to locate the Keystone of Hercules which was now very close to the Zenith. Once found visually, used my binoculars to find the little grey fuzzy M13.

Ophiuchus, M10, M12, Serpens Caput, Serpens Cauda
Time: 10:02

Equipment: Visual, Binoculars
S&T Chart: 54, 56
It was on this site that I first identified this constellation in 2017 and was amazed it took up a great deal of sky real estate. I know its components quite well and identified all the stars visually from its tip (Rasalhague) to its toes (Sabik, to Yed Posterior and Yed Prior). I also knew the constellation Serpens which I typically break into its two components - Serpens Cauda (the snake tail) and Serpens Caput (the snake head). 

Ophiuchus has two Messier objects that I easily find with binoculars - M10 and M12. I use δ Ophiuchus (Marfik) and head into constellation, finding the small grey fuzzy M12 first. Another FOV inwards and M10 comes into view. Comforting to know how to find them. 

Scutum Star Cloud, M11
Time: 10:15 PM

Equipment: Visual, Binoculars
S&T Chart: 54, 56
Another of my favourite areas! The top of the Scutum Star Cloud has two stars (β Scutum and η Aquila) from which I can then find M11 ( the fuzzy  grey 'golf ball') and its adjacent 7-star 'golf club'. The 4 stars of the constellation Scutum were easily found as well.

Cygnus,  North America Nebula
Time: 10:15 PM

Equipment: Visual, Binoculars
S&T Chart: 54, 56
Going up along the Milky Way, I came across Aquila then continued upward to Cygnus, following it from Albireo up to Deneb. Dave described how to find the North America Nebula using Deneb, ξ Cygni and ν Cygni. However, still no luck finding it.

Aquarius, Neptune 
Time: 10:28 PM

Equipment: Visual, Binoculars
S&T Chart: 75,76
I was able to locate all the stars in the 'bucket' of Aquarius - δ Aqr, 88 Aqr, 98, Aqr, 99 Aqr, ω Aqr, ψ Aqr and θ Aqr. Little blue Neptune was found about 3° away from ψ Aqr.

Capricornus, Jupiter
Time: 11:05 PM

Equipment: Visual, Binoculars
S&T Chart: 75, 76
Capricornus always makes me smile. To me, it looks like the big grin a clown would paint on their face. Most of its main stars were located. Jupiter was visually located as one side of a triangle with Deneb Algiedi and Nashira. Using my binoculars I discovered Europa very close to the planet with Ganymede and Callisto close together and a little further out on the same side. Io was on the other side.

Cetus
Time: 11:23 PM

Equipment: Visual
S&T Chart: 4, 6
I recognized a star formation that I suspected was part of Cetus. I was correct but only the 'tail' portion was visible. ι Cet was furthest up in the sky; ß Ceti (Diphda) was also visible and quite bright.

Winter Circle, Pleaides
Time: 4:40 AM

Equipment: Visual
I woke up because "nature called" so decided to go out to the beach to see what I could see. And there it was - the Winter Circle! Starting with Orion and his contribution Rigel, then Canes Major and Sirius, Canes Minor and Procyon, Gemini's Pollux and Castor, Auriga's Capella and leaving Taurus to finish the circle with Aldebaran. I had to looked away from Taurus towards Perseus to discover the Pleaides, a.k.a. M45. Within the open cluster is a group of stars forming the shape of a mini-shopping cart. Another beautiful star formation with such beautiful nebulosity.

IWLOP #102 - Mare Cognitum & Kuiper

IWLOP #102 - Mare Cognitum & Kuiper

Mare Cognitum, the “Known Sea,” was named in 1964 to mark the successful flight of the Ranger 7 spacecraft, which sent back the first detailed television pictures of the lunar surface. Kuiper, located in central Cognitum, is an excellent example of a small, simple crater.

Location: 9.8 S 22.7 W    Origin: Impact     Size: 6.8 km (Kuiper)   Rukl: 42     Type: Simple Crater (CS)

Objects: Mare Cognitum, Ranger 7 landing site, Kuiper, Darney, Mons Moro
Others Identified: Darney C, Eppinger

Observation 1:
Location: Home
Date: 2020-08-28
Time: 8:30 PM ADT
Equipment: 10” Meade SCT
Eyepiece: Explore Scientific 12 mm eyepiece with 92° FOV
Magnification: x210
Seeing: Very Good (4)
Transparency: Very Good (4)

R1: Mare Cognitum is between Oceanus Procellarum in the northwest, Mare Nubium in the southeast, and Mare Humorum in the southwest. The Ranger 7 landed southeast of Kuiper.
R2: Kuiper is in the centre of the mare in what appears to be a flat plains. Darney is located in a rugged mountainous area south of Kuiper and appears to be about twice the size of Kuiper.

C1: There are several wrinkle ridges throughout the Mare.

Observation 2:
Location: Home

Time: 9:30 PM ADT
Equipment: 10” Meade SCT, 4.7 mm eyepiece
Magnification: x530
Seeing: Very Good (4)
Transparency: Good (3)

C2: Mons Moro appeared as a small raised area or mountain (?) SW of Kuiper and NW of Darney on Mare Cognitum. Couldn't make out any distinctive features.

NOTE: (July 15, 2021) Investigated to confirm my findings last year regarding size and found that Darney's width is 15 km which is a little more than twice the size of Kuiper. Good guess on my part.

Kies is a flooded crater with a nearby volcanic dome designated π (Pi). Mercator and Campanus are two nearly equal-sized craters located at the edge of Mare Nubium.

Location: 26.3 S 22.5 W    Origin: Impact     Size: 44 km (Kies), 47 km (Mercator), 48 km (Campanus)  
Length: 180 km (Rupes Mercator)    Rukl: 53     Type: Complex Crater (CC)

Objects: Kies, Bullialdus, Mercator, Rupes Mercator, Volcanic Dome Kies π, Campanus
Others Identified: Capuanus, Capuanus A, Bullialdus A & B, Campanus A, Dunthorne, König & König A, Marth, Ramsden

Temperature: 17° C
SQM: 18.86

R1: Directly south of Bullialdus is Kies. It's walls are barely seen; the SW has a small area that is quite high. It's shaped like a small magnifying glass, short handle that may be higher in elevation than the crater walls.
R2:  Mercator does not have a peak and is shallower than Campanus and perhaps more worn. Campanus is NW of Mercator.  Rupes Mercator begins at Mercator's rim and goes southeasterly towards Rima Hesiodus. 

  

C1:  The volcanic dome just west of Kies designed π was observed; it appeared as a slightly raised area.
C2: Mercator does not have a peak whereas Campanus does. Campanus has a peak, its floor is darker and its sides steeper than those of Mercator. The unnamed rille appears as a thin dark line between the two craters; the south section curves into an area between the craters then heads north towards the small mountains on the mare floor.

There was cloud cover from 11:40 PM to 11:55 PM. Knew where to look once clouds opened for viewing.

R1: Delisle is a little deeper than Diophantus; both are round but couldn't see either floor. Mons Delisle appears as a partial semi-circle, almost tooth-shaped with the point well lit and the base darker. Mons Delisle is steep-sided on the inner curve.
R2: Diophantus shallower than Delisle, has a central peak with a ridged west wall. Mons Vinogradov shows 2 bright areas in the SE. The whole area looks triangular in shape with the 2 bright spots on one of its sides. Also, several domes (approximately 12) were seen east of the Mons.

IWLOP #117 - Mons Gruithuisen Gamma (ϒ) & Delta (δ)

Impressive twin-shield volcanoes on boundary between Mare Imbrium and Oceanus Procellarum.

Location: 36.3 N 40.0 W    Origin: Volcanic     Size: 20 km each     Rukl: 9     Type: Domes

Objects: Mons Gruithuisen Gamma (ϒ) & Delta (δ), Mairan T, Sinus Roris, Mairan

Location: Home
Date: 2021-06-20

Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm with 82° FOV

Magnification: x530
Seeing: Excellent (5) 
Transparency: Very Good (4)

R1: The two domes stood out as bright, white entities like sentries standing guard at the entry to some highlands/craters. Delta wasn't as bright as Gamma but Gamma was tall enough to cast a shadow on Delta. Delta appeared elongated compared to the rounded Gamma. Tall shadows created by both.

The crater Gruithuisen appears round with a bright rim. Upon closer examination, I realized a small crater had impacted the rim, giving me the false initial impression of a deteriorated wall.

 

C1:  Could not see the summit crater on Mons Gruithuisen Gamma.
C2: Most of Mairan was in shadow. Mairan T was beyond the terminator.

General Session - June 10, 2021 (Annular Eclipse)

Sun
Moon

Location: Site 1, Kejimkujik National Park
Date: 2021-06-10
Time: 5:15 AM - 7:30 AM AST
Instrument:  Binocular 10x42 IS
Transparency: Excellent (5)
Seeing:  Excellent (5)
Temperature: 11˚ C - 13˚ C

We were camping on Site 1 of Big Dam Lake the night before and did some evening observing. For us to observe the eclipse we had to get up early and canoe across the Lake as the eclipse was happening above and behind our campsite. So up at 4:00 AM, had a partial breakfast then paddled the short distance across the Lake onto the marshy shore opposite our site and sat there to view this phenomena.

If you zoom in to the blue dot below Judy's elbow, you will see
the camera's internal reflection of the eclipse.

Very windy. High cloud in the west eventually drifted into our horizon but did not interfere with the initial phases. There was a bit of Earthshine on the Moon, especially on its eastern limb; thought I could make out Mare Crisium and 2 other Mare. The clouds rolled in, preventing us from watching the Moon leave the solar orb.

Constellations: Corona Borealis, Corvus, Crater, Libra, Scorpius, Sextans
Stars: Antares, Brachium, α Crt, β Crt, α Alchiba, δ Algorab, γ Gienah, β Kraz, Alpheca, ε Minkarα, Sextans, β Sextans, γ Sextans, Zubenelgenubi, Zubeneschamali

Location: Home
Date: 2021-06-09
Time: 10:00 PM - 11:25 PM ADT
Equipment: 10x42 IS Binoculars
Temperature: 17° C - 15° C
Transparency: Excellent (5) but deteriorated to 2
Seeing: Excellent (5) but deteriorated to 3

No wind. High cloud in the west eventually drifted to our horizon. Could not view Ophiuchus as it was hidden by the trees over our beach area. I had brought along my newly acquired mini 2.1 x 42 Binoculars to try out.

Corvus
Equipment: Visual, 10x42 binoculars
S&T Chart: 47
Corvus was easily located. The 5 main stars (α Alchiba, β Kraz, δ Algorab, γ Gienah, ε Minkar) and two smaller one (η near Algorab, ζ that formed a triangle with Minkar and Kraz). η appeared to be very close to Algorab, making it appear as a double star.
   

Crater
Equipment: Visual, 10x42 binoculars
S&T Chart: 36
Being adjacent to Corvus made this constellation easy to find. α Crt and β Crt were below the treeline on the other side of the pond so could not be seen. The stars in this constellation were not as bright as those in Corvus.

Sextans
Equipment: Visual, 10x42 binoculars

S&T Chart: 36, 37
I saw a triangle shape of stars low on the horizon, adjacent to Crater above the trees. Α Sex, β Sex and γ Sex were identified as the three stars observed. I always confuse this constellation with Triangulum which is further north near Aries and Andromeda. 

Corona Borealis / Northern Crown
Equipment: Visual, 10x42 binoculars
S&T Chart: 53, 55
This semi-circle of stars is one of my favourites to locate. It's next to Boötes (and Arcturus), and I use it to locate the Keystone of Hercules and M13. Did not look for M13 this particular evening. The 7 stars stood out, especially Alpheca. On this particular night, the crown looked more like a cup, with its opening pointing straight up.

Libra
Equipment: Visual

S&T Chart: 46, 57
This large triangle-shaped constellation never disappoints, especially when one has such fun pronouncing its α and β star names. I was able to locate Zubenelgenubi, Zubeneschamali and Brachiium. Did not search for the other 3 main stars.

Scorpius, M4
Equipment: Visual, 10x42 binoculars

S&T Chart: 56, 58
The claws and most of the body of Scorpius were identified; however, the tail stars were not visible above the horizon. Antares was very red this evening. σ Scorpii was easily seen and with the binoculars could easily find the faint fuzzy M4. I did not look for M80 which was at the same declination as δ Scorpii.

Date: 2021-05-24
Time: 9:58 PM - 11:28 PM ADT
Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm eyepiece with 2x Barlow

Magnification: x1000
Seeing: Very Good (4)
Transparency: Good (3)

RI: Reiner Gamma is very white on dark mare floor.
R2: Galilaei is oval looking and small. Bright west wall due to terracing/slumping (?).
R3: Planitia Descensus
has a north ridge that's beside a dark lava area, the latter of which appears to be flat.
R4:
The Luna 8 landing site is approximately half way between Galilaei and Planitia Descensus in what appears to be a relatively flat, crater-free area.

C1: Sketch of Reiner Gamma is below.

 

Note: The craters Cavalerius and Hevelius are west of the Luna 8 landing site.

IWLOP #030 – Hommel

Extremely complex crater with several overlapping structures.

Location: 54.6 S 33.0 E   Origin: Impact    Size: Crater 125 km    Rukl: 75     Type: Complex Crater (CC)

Objects: Hommel, Pitiscus, Vlacq, Rosenberger, Search, Biela, Hagecius

Location: Home
Date: 2021-05-20

Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm with 82° FOV

Magnification: x530

Transparency: Very Good (4) 

R1: Located Hommel SSW of Janssen. Identified its craters A, B, C, D, H and P. Also located J, Q, R, S, and V.

NOTE: It was difficult to discern exactly where this crater's walls were located given the numerous impacts it had on or near its original walls. Took a photo at the telescope of what I was viewing then used Rukl to help determine what I was seeing. 

R2: Pitiscus had an off-centre crater next to a raised formation; there was a terraced SW wall with a crater.

Vlacq appears to have sharp edges and perhaps 2 peaks or a split central peak.

Rosenberger is shallower and its SW rim appears worn.

 

C1: Biela is an oval with crater C impacting its NE rim; crater A is just above crater C.

Nearch and its crater A were also identified. Hagecius has large craters B and C on its SE walls.

IWLOP #025 – Mare Nectaris ("Sea of Nectar")

IWLOP #025 – Mare Nectaris ("Sea of Nectar")

The smallest of the major circular maria at 350 km across, it formed about 3.92 billion years ago. Even though Mare Nectaris is relatively small compared to other large basins, it still covers over 10 degrees of the lunar surface and may require various terminator angles for optimum views of all the features listed below. The absence of rilles may relate tot he relative thinness of lava in this mare.

Location: 15.0 S 40-30 E     Origin: Impact and Volcanism      Size: 350 km      Rukl: 58, 47     Type: Basin

Objects: Mare Nectaris, Bohnenberger, Rosse, Beaumont, Daguerre
Others Identified: Capella, Fracastorius, Isadoris, Mädler, Theophilis

Location: Home
Date: 2021-05-17
Time: 9:30 PM ADT
Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm with 82° FOV + x2 Barlow

Magnification: x1060
Seeing: Excellent (5) 
Transparency: Very Good (4) 

R1: Wrinkle ridges on eastern areas of Mare Nectaris and west of Bohnenberger are almost parallel to Montes Pyrenaeus. Arcurate rilles not evidenced.

C1: Bohnenberger is west of the lower half of the Montes Pyrenaeus. Rosse is slightly off-centre of the Mare and it appears that its ejecta runs north-south with some going eastward. Beaumont (west of Fracastorius) looks to have its northern rim eroded; couldn't see features on its floor.
C2:  Daguerre at this point in the lunation appeared almost as a ghost crater. However, the ejecta ray from Mädler goes through one of the craters just inside Daguerre's eastern rim, and that helped identify Daguerre's location.

R1:  Wohler has no central peak; its SW wall is wider and steeper than the NE wall. Not as deep as Stiborius.  Stiborius has a central peak and appears to be in a relatively flat area (of another crater?). The SW wall is particularly steep, and wide walls in the SW. Stiborius C much shallower and smaller.

C1: Nicolai looked circular with 2 craters on its north wall and had a flat floor. Nicolai A also noted. Spallanzani looked to have a small crater on its west wall and was much smaller than Nicolai. Because Spallanzani was close to the terminator, I couldn't see its floor or interior rim details.
C2: Numerous craters were seen in this area - craters upon craters.

R1: Zagut had the large central Zagut A on its floor and Zagut E on its east wall. Rabbi Levi had 5 craters in its western floor plus numerous others on its eastern wall. Lindenau had 2 peaks split by a rille; its western wall appeared terraced/slumped almost to the peaks.

R2: The circular Rothman was located northeast of the trio craters and had a central peak plus steep walls.

Celsius was west of the three, forming a triangle with Zagut and Rabbi Levi. Besides the north crater on its floor, there appeared to be other structures such as rilles on its north floor. Every wall of Celsius appears to have small craters.

R1: Bohnenberger was on the west side of Montes Pyranaeus; small craters to the north and south. A north crater and Bohnenberger appear to form the exterior walls of a valley. Half way up , there is an east-west break the mountain range. There's a jagged ridge on the the N side of the valley - both sides of the valley, actually. The valley looks to be crossed with 2 ridges.

The Montes Pyrenaeus appears short with interruptions, but its western edge appears to be continuous from Bognenberger to Gutenberg.

R1: Metius B was located on the NE floor of Metius. Fabricus had me questioning why there was a darkness on the floor, like a large rille or rima encircling 3 of the 4 sides of the floor.

C1: Brennar looks like a small flame or leaf. Brennar A impacted on its SE rim and could also see E on its NE rim.

Had a much clearer view of Fabricus.

NOTE: Discovered in Rukl 68 there are 2 central ridges that create shadows on 2 sides of the crater. The 3rd side is steep near the crater floor and casts another portion of dark shadow. With this magnification, there was clearer definition of the rises on the crater floor as shown in Rukl.

Explore the Moon (Telescope) - May 15, 2021

Lunar Phase: Waxing Crescent (9.7%)
Q-Day: -4

Moonrise: 8:10 AM                   
Sunrise: 5:46 AM          Sunset: 8:37 PM

Location: Home
Date: 2021-05-15

Observation 1:
Time: 9:00 PM – 9:50 PM
Temperature: 8° C
SQM: 18.56
Equipment: 6” Dobsonian, 9.7 mm + 15 mm eyepieces
Magnification: x124 + x80
Transparency: not recorded
Seeing: not recorded

Quite excited when my Moon app showed that Newcomb - the last object to be viewed - could potentially be seen. Quickly set up the Dob and inserted the 9.7 mm eyepiece. The image as not only backwards but also upside-down. How confusing!

Once I had it figured out, I recognized Cleomedes, Burckhardt and Geminus as the 3 large craters “below” (in reality it was above) Crisium. Macrobius was located on the west side of Crisium. I then identified Lacus Bonitatis; there appeared to be a bay or plateau “below” it and Newcomb was beside this not too far from the terminator. Consequently, did not get a good view of the crater. Perhaps I need to wait a while and try again?

Observation 2:
Time: 11:05 PM – 12:00 AM
Equipment: 10” Meade SCT, 9.7 mm + 15 mm + 4.7 eyepieces
Magnification: x258 + x167 + x532
Transparency: not recorded
Seeing: not recorded

Moon was getting quite low and there was light cloud cover occasionally. I tried all three eyepieces; the 4.7 mm was too zoomed in and difficult to focus at x532 magnification.  However, even though it was almost 2 hours later, I was unable to get the detail of the crater itself. Therefore, no sketch.

Looking at Rukl 25 and comparing it to the view I had in the telescope and later in the very fuzzy photo I took with my iPhone, I could identify A, B, C, J and G beside it but could not describe any details. Montes Taurus was seen briefly as they were on the terminus. Lesson learned – take out the big scope first!

 

Maria, etc.: Lacus Bonitatis

Craters: Cleomedes, Newcomb, Macrobius

IWLOP #122 – Aristarchus Plateau & Vallis Schröteri

IWLOP #122 – Aristarchus Plateau & Vallis Schröteri

Aristarchus is a bright, complex crater that is a little older than Tycho, and is located near the edge of a unique plateau that rises 2 km over Oceanus Procellarum. Vallis Schröteri was a lava tunnel that carried lava from the highland plateau to the adjacent basin.

Location: 23.7 N 47.7 W   Origin: Impact and Tectonic    Size: 40 km (Aristarchus), 230 km diameter    Rukl: 18    Type: Complex Crater (CC) and Valley

Objects: Aristarchus, Mare Procellarum, Oceanus Procellarum, Vallis Schröteri, Montes Agricola, Rupes Toscanelli, Toscanelli, Rimae Aristarchus, Herodotus, Mons Herodotus

Eyepiece: Explore Scientific 4.7 mm with 82° FOV
Magnification: x530
Transparency: Good (3)
Seeing: Good (3)

R1: Aristarchus was quite bright. Bright rays of ejecta to the south and west. The diamond-shaped plateau was darker than the surrounding Oceanus Procellarum. Ejecta may have gone as far as Montes Carpatus and meets those of Kepler in the south. 
R2: Vallis Schröteri starts on Oceanus Procellarum, meanders N, then NW, then South. The rille ends in a cobra head north of Herodotus.
R3: Montes Agricola well lit on the eastern slopes. It formed a border of the diamond plateau.

C1: The 3 rilles not observed at this time.
C2: Saw the cobra head NE of Herodotus.
C3: Mons Herodotus was a singular bright spot between the Vallis and Montes Agricola. Two other bright "spots" to the North but too far to be related (?).

This was my first observing of this feature. It seen again on July 10, 2022 (General Session - July 10, 2022 (Sleepover)) with our youngest granddaughter.

IWLOP #115 - Kepler & Encke

Recent impact crater Kepler (32 km), with its uneven floor and bright ray system, contrasts with older crater Enke of nearly the same size.

Location: 8.1 N 38.0 W    Origin: Impact     Diameter: 32 km (Kepler), 29 km (Encke)   Rukl: 30    Type: Complex Crater

Objects: Kepler, Encke

Eyepiece: Explore Scientific 4.7 mm with 82° FOV

Magnification: x530
Seeing: Good (3) 
Transparency: Good (3)

R1: Kepler deeper than Encke. Kepler, because of its size, gave me the initial impression it was shallower until I looked at it in more detail using a different eyepiece (9.7 mm vs. 4.7 mm). Kepler's floor and inner walls quite bright compared to Encke.

C2: The tiny crater N was barely discernible on the west wall of Encke. It took patience; had to wait for the seeing to improve.

I decided to have another look at these two craters.

  • Kepler was now evidently quite deep with the floor mostly in shadow due to the steep walls.
  • Encke's flat(?) floor was exposed. A small crater in the north wall was very noticeable.
  • Maestlin, southwest of both craters, was visible. It was small, possibly steep-sided with its crater rim well lit. Its floor was very small and dark.

IWLOP #013a – Eastern Mare Fecunditatis

A mare consisting of two contiguous, nearly round areas of dark Basaltic lavas. The northern part is three times larger than the southern and exhibits a number of dorsa. These lavas probably overlie an impact basin of pre-Nectarian age. Mare Fecunditatis covers 20 degrees of the lunar surface and may require various terminator angles for optimum views of all the features listed below. 

Location: 4.0 S 42-62 E     Origin: Impact and Volcanism      Size: 990 km.      Rukl: 48      Type: Basin

R1: Montes Taurus appeared as a raised cratered area. Römer was a slightly elongated circular crater with wide slumped walls. Its central peak was wide and slightly elongated. The tiny crater in its north wall was quite bright compared to the coloration in the walls and floor.
R2: Maraldi is dark-floored with irregular SE and NW walls. Mons Maraldi, north of the crater, is a small oblong structure that is not very high.
R3: Hill and Carmichael are to the east. Their west interior walls were quite bright making them easy to identify.

R1: Albulfeda has a flat floor with a small central crater. Whereas most of the walls look thick and terraced, the W wall looks steep/ridged.
R2: The Catena Albufeda begins at Albufeda's S-SW, travels just north of Almanon, then curves SE below Tacitus to join the northern Rupes Altai.

C1: Some craters on the north wall of Albufeda are smaller and shallower than others.
C2: I could make out at least 5 secondary craters on the N wall.
C3: 
Think I saw the 4 craterlets that begin the Catena on the south wall of Albulfeda when the seeing improved. Most were small and in the crater wall.

R1: Stadius appears as a ghost crater. The tallest part of Stadius' crater walls is in the NE and SW. The NW and SE crater walls don't appear - flooding? disintegration? or both? There were hints of numerous very small craters on its floor, but I wasn't sure.
R2: Two dark patches were located on the floor of Mare Insularum to this crater's south.
R3: The prominent mountain massif between Stadius and Eratosthenes is HUGE compared to Stadius but is comparable in height to Eratosthenes. It was also very bright - you couldn't miss it!

Just started to identify where I was on the lunar surface when our grandson William and his parents arrived. As he arrived, I had located Stadius. After showing him the crater and explaining its features, he used the hand controller to look for craters that interested him. They left around 8:30 PM.

My greatest success this evening? Apollo 16 landing site!!

It was in a relatively “flat” area surrounded by a ring of craters. Beginning at the north and going clockwise:
* Taylor
* Lindsay
* Andel
* Dolland (very tiny crater)
* Descartes
* Kant
* Zöllner

Alfraganus was also located while looking for Albulfeda.

NOTE: Discovered afterwards that Apollo 16 landed on the Cayley Plains.

It was fun seeing features under a different light from previous observations. The "re-discovered" features viewed in a bit more detail were:
   - Cassini and Vallis Alpes. Refer to IWLOP #68 - Montes Alpes & Vallis Alpes and Explore the Moon (Telescope) - April 19, 2021. 
   - Purbach with its line of crater that broke its north wall and continued onto its floor. Refer to IWLOP #73 - Regiomontanus & Purbach for more details.
   - Walther to the south of Purbach also had an interesting line of craters across its floor. Refer to IWLOP #71 - Walther for details.

Eyepiece: Explore Scientific 4.7mm with 82° FOV

Magnification: x530
Seeing: Good (3)
Transparency: Very Good (4)   

R1: Arago and Ross are SE and NE respectively of Julius Caesar.
R2: Lamont was barely visible on the mare floor. Flooded or worn down(?).
R3: Ritter and Sabine both located. Ritter B, C and D were visible. Schmidt was to their SW. They looked to be similar depths but Ritter's walls looked sharper. Sabine's south wall appears to have a break. There is a ridge from Rimae Hypatia that seems to affect it.

C1: The two nearby domes designated Alpha (α) and Beta (β) appear circular, lighter in colour than the Mare floor.
C2: Could not see the summit pits on the Arago domes at this time.
C3: The Ross peak is offset towards the E on its floor. The central peak of Arago appears to join to the north crater wall.
C4: Armstrong, Aldrin and Collins were all seen during brief periods of better seeing. Armstrong appears to be larger than the other two (refer to IWLOP #045 – Moltke & Rimae Hypatia for sketch of location of the 3 craters).

IWLOP #057 - Linné

The actual crater is a small difficult object but the bright halo around it is easy to spot. Linné has been described as a crater, cloud, crater-cone, or pit in a depression. The true nature of this bright and simple crater was settled using Apollo photos.

Location: 27.7 S 11.8 E    Origin: Impact     Size: 2.4 (actual crater); bright halo larger     Rukl: 23     Type: Simple Crater (CS)

Objects: Linné

Seeing: not recorded

The Moon was adjacent to Pollux and Castor in Gemini.

Nothing “new” found for this program but did review some features and found others for the IWLOP. It was fun seeing features under a different light from previous observations.

The first “re-discovered” features were Vallis Alpes in the Montes Alpes and Cassini to its south.

Cassini was viewed quite well, this time with the higher magnification being able to see craters A and B on its floor.

Next was Purbach with its line of craters that broke its north wall and continued onto its floor. Walther to its south also had an interesting line of craters across its floor.

I then revisited Julius Caesar at 9:18 PM. I had viewed it 2 years ago, but the floor could not be seen well at x250 magnification. This time I used a 4.7 mm eyepiece with a x2 Barlow to obtain x1000 magnification. It was then I noticed that the E and SE walls were in essence non-existent. There was a line of small craters across the east wall from SE-NW. There was a small crater on the NW wall.

Lunar Session - April 15, 2021

This session was devoted to lunar observing. A couple of IWLOP objects were viewed.

Lunar Phase: Waxing Crescent (13.1%)
Q-Day: -5

Moonrise: 8:17 AM       Moonset: 11:43 PM
Sunrise: 6:30 AM          Sunset: 8:00 PM

Location: Home
Date: 2021-04-15
Time: 8:00 PM - 9:30 PM

No wind or clouds at the start of the observing session.

Vallis Rheita was the target. This was 1 of 2 unobserved objects in the RASC Explore the Moon (Binocular) and one of many yet to observe for the Isabel Williamson Lunar Observing Program (IWLOP). I also found features not required for this session - Lacus Temporis, and the craters De La Rue, Strabo, Thales and Langrenus.

Found Vallis Rheita! It looked like a series of small craters running north to south, almost like a rib cage with no spinal column attached. The crater Rheita was at the north end with Mallet in the South. Refer to IWLOP #14 - Vallis Rheita for more details of this observation.

I was able to observe and sketch the following items for inclusion in IWLOP. Had lots of fun exploring the surface of the Moon for exciting new-to-me features.
   - IWLOP #9: Endymion & Mare Humboldtianum: I was able to sketch the crater but the mare was only partially completed in this session.
   - IWLOP #10: Snellius & Vallis Snellius
   - IWLOP #12: Stevinus
   - IWLOP #35: Jansen

NOTE: Jansen (found in the north part of the Mare Tranquillitatis) is not to be confused with Janssen (found near the SE lunar limb).

No breeze to mention and no clouds to begin this session.

8:10 PM:
The first target was Vallis Rheita, the second last target on the ETM list for me to find. FOUND! It looked like a series of craters running almost straight north south. The crater Rheita was at its north end; Mallet was at the south end. Identified in this area of the lunar surface were:

  1. Craters: Breila, Hagecius, Mallet, Rheita, Steinheil, Watt, Young. Rosenberger was deep in shadow on the terminator.
  2. Valley: Vallis Rheita

8:38 PM:
Also looked at Snellius and Stevinus just north on the terminator. The more southerly Stevinus had a central peak, quite large actually. Snellius had no central peak and its southern rim looked warn down or perhaps it was lava inflow or ejecta (?).

Identified in this area were:
a)     Craters: Borda, Furnerius, Petavius, Reichenbach, Snellius, Snellius A, Stevinus, Stevinus A. Santbech on the terminator so that only the SE exterior crater wall was visible.
b)     Valley: Vallis Snellius

8:50 PM:
Searched for and found Endymion – slightly elongated with flat floor. NW wall seems to be at edge of higher, flat area.

Lacus Temporis to its south, de la Rue, Strabo and Thales to its north.

Identified in this area were:
a)     Craters: de la Rue, Endymion, Strabo, Thales
b)     Lake: Lacus Temporis

(Note: Sketch from
IWLOP #9: Endymion & Mare Humboldtianum)

9:00 PM:

Went more southerly to find Langrenus and Vendelinus plus part of the Mare Fecunditatis. I was able to identify several craters adjacent to these two craters: Atwood, Barkla (I think), Bilharz, Holden, Kapteyn, Lamé, Lohse, Noanubu.

Also had a great view of Mare Crisium and its craters and several other features:

  1. Craters: Alhazen, Condorcet, Firmicus, Greaves, Hansen, Picard, Pierce, Shapley, Swift, Taruntius, Yerkes
  2. Dorsa: Dorsum Oppel, Dorsa Harker
  3. Lacus & Maria: Mare Undarum, Lacus Perseverantiae
  4. Promontorium: Agarum

Just as John Read suggested in the Moon at Noon, a smiley face appears when you consider Picard and Pierce as eyes and Dorsum Oppel plus the wall of Yerkes as the mouth.

Lacus Perseverantiae came as a surprise! Thought it was just a “space” between Firmicus and the SE of Mare Crisium. Wasn’t until I looked more closely at my lunar map that the area was identified.

R1: Moretus is located SE of Clavius and has an oval shape. It's floor appears smooth except in its southern areas.
R2: Deep terraced walls easily identified. East walls seem steeper than those in the west. Central peak appears quite steep and is almost V-shaped. The joined Cysatus and Gruemberger are NW of Moretus; Cysatus appears to have impacted Gruemberger obliquely.

C1: All 6 craters were located. Short is south, much smaller and shallower. Newton's east side was largely in shadow and the crater may be deeper than is Short. Curtius, Zach and Pentland form a triangle to the NE. Simpelius in the east has a central peak. None of the craters appear as deep as Moretus.

IWLOP #108 - Palus Epidemiarum

IWLOP #108 - Palus Epidemiarum 

One of only a few lava-flooded areas located in the southern highlands of the Moon. It has an irregular shape, a dark floor, and two rille systems.

Location: 32.0 S 27.0 W    Origin: Flooded lava plain     Size: 300 km   Rukl: 63, 62, 53, 54     Type: Palus

Objects: Palus Epidemiarum, Capuanus, Ramsden. Rima Hesiodus, Hesiodus, Pitatus, Rimae Ramsden, Cichus, Weiss, Dunthorne, Lepaute
Others Identified: Elger

Temperature: 4° C
SQM: 18.56

 

R1: Located Palus Epidemiarum. Capuanus has low NE walls with similar dark-coloured floor as does Palus. Ramsden was rounded with a steep rim and shadowed crater floor.
R2: Actually followed Rimae Hesiodus from Hesiodus to the NW ridge of Capuanus. Interesting how it cut through several lines of mountains and the floors of both Mare Nubium and Palus Epidemiarum. 

C1: Rimae Ramsden began near Elger, formed a "Y" near Ramsden; one line continued past the NE wall of Ramsden then formed a backwards "N" shape between Ramsden and the mountains to its N-NW. Cichus was located on the E-SE shore, Weiss NE of Cichus, Dunthorne north of Ramsden and Rimae Ramsden, and Lepaute was west of Ramsden.

IWLOP #082 - Davy & Catena Davy

IWLOP #082 - Davy & Catena Davy

Notable crater with a nearby chain of 23 very small craters likely caused by a fragmented comet or asteroid impacting the Moon.

Location: 11.0 S 7.0 W    Origin: Impact     Size: 35 km (Davy), 47 km long (Catena Davy)     Rukl: 43      Type: Crater and Catena

Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm with 82° FOV

Magnification: x530
Seeing: Very Good (4)
Transparency: Good (3)

R1: Davy is a circular crater with a central peak; its east and west walls looked collapsed. Davy A was round, sharp-rimmed and had impacted the SE wall of Davy.
R2: North of Davy were two craters - Mosting and Lalonde. They looked circular, sharp-rimmed and were closer to Flammarion than to Davy. Palisa was a crater that looked like it impacted the north of Davy Y but the wall between them was somewhat eroded/collapsed.


C1: The line of craters were seen at 9:40 PM viewing of this area. It began at Davy G, headed across the plain and terminated near Davy C.

NOTE: I came across these features quite by accident when searching for the Fra Mauro Formation. Catena Davy was so clear! I was quite excited because a friend had searched for and found it a night or two before and we could now compare notes.

Eyepiece: Explore Scientific 4.7mm with 82° FOV
Magnification: x530
Seeing: Very Good (4)
Transparency: Good (3)
Temp: 5º C
SQM: 18.63 

R1: Pitatus on southern border of Mare Nubium. Very irregular and poorly defined rim due to fractures and impacts. Large central peak is off-centre. Walls in the northwest are particularly eroded.

C1: Could easily see Rimae Pitatus along the NE and East side close to the rim. Also saw a bit of the Rimae in the NW. Could see some approaching the off-centre peaks but most was seen just inside the crater wall on the floor. The eastern floor was just a bit darker than the western floor.

Note: I was pretty excited to have the dark line going almost all the way from the crater wall  to the off-centre peak confirmed after sketching. I was prepared to erase it if indeed I was imagining the dark line that may be a rille.

Magnification: x530
Seeing: Very Good (4) 
Transparency: Good (3)

R1: Fra Mauro is almost flooded and has eroded crater walls; some areas of the wall are non-existent. Only the rim in the NE seems to remain; Bonpland and Parry have impacted the southern walls. Crater floor appears rough. Apollo 14 landing site just north of the crater appears to be a higher elevation.
R2:  Parry appears to have a few breaks in its rim that do not appear to be very high. Bonpland is more like a ghost crater, perhaps filled with lava or covered with ejecta blanket. 

 

C1:  Rimae Parry has more than one section:
   * Section 1 crosses the SE rim of Parry in a NE direction before crossing the east rim and continuing a short distance into the Mare.
   * Section 2 extends from the crater Tolansky across the west side of Parry and into the Fra Mauro crater.
   * Section 3 crosses the north rim of Bonpland and into Fra Mauro.
C2:  Dorsum Guettard begins at the southwest rim of Bonpland and ends somewhere around Crater D. It does have a slight curve to it.

IWLOP #018 – Palus Somni & Proclus

IWLOP #018 – Palus Somni & Proclus

Palus Somni, the "Marsh of Sleep," is a dark continental area west and south of Proclus. It's area is defined by an oblique impact that created a differential ray system. The unique character of this area is often best seen after Full Moon.

Location: 14.0 N 45.0 E     Origin: Tectonic      Size: 56 km, 40 km      Rukl: 37, 26     Type: Palus, Crater & Ray System

R1: Palus Somni is located on the NW side of Mare Tranquilitatis. Proclus is between Palus Somni & Mare Crisium. Proclus appears very white compared to its surroundings.
C1: Bright rays from Proclus go eastward into Crisium; none towards Palus Somni. 

NOTES:
1- The extent of the differential rays east and west of Proclus were drawn in the sketch; I didn't used the IWLOP template.
2- Palus Somni had a lighter grey shade/hue in colour compared to surrounding formations. It also appeared rough in terrain with numerous ridges and/or craters.
3- Proclus was oval-shaped. It's NW rim appeared shallow and had numerous ridges that were very white. The floor appeared very pale grey.

IWLOP #029 - Fracastorius

IWLOP #029 - Fracastorius

Since this crater intersects the Nectarian Basin wall, it formed after the Nectarian Basin impact but before the area was flooded with lava.

Location: 21.2 S 33.0 E   Origin: Impact    Size: 58 km    Rukl: 58     Type: Complex Crater (CC)

IWLOP #049 - Sacrobosco & Playfair

IWLOP #049 - Sacrobosco & Playfair

Sacrobosco is a pre-Nectarian crater and Playfair is Nectarian. The eroded Playfair G directly west of Playfair is pre-Nectarian since it is covered by deposits of probably Nectarian age. Sacrobosco and Playfair are located at widely separated longitudes so you may need to wait for the terminator to observe them both at the same time.

Location: 23.7 S 16.7 E    Origin: Impact     Size: 98 & 48 km     Rukl: 56     Type: Complex Crater (CC

Objects: Playfair, Playfair G, Sacrobosco

Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm with 82° FOV

Magnification: x530
Seeing: Very Good (4)
Transparency: Very Good (4)  

R1: Playfair appears to be deeper than Sacrobosco and Playfair G. The latter 2 have rims that appear flatter and have been hit by objects to create numerous craters on their floors and rims. Sacrobosco's west rim is very terraced and has 3 craters on its smooth floor (A, B, C). The eastern crater floor appears darker on one side of the ridge compared to that of the western floor.

C1: The 2 craters in Playfair are in the NW quadrant. The 4 craters in Playfair G form a loose square around the centre point. Very tiny craters in all 6 cases. Also, it appears that Playfair was formed after Playfair G as Playfair changes the shape of G's rim.

R1: The crater Hyginus was found in the middle of the curved Rima Hyginus.

R2: South of the Rima's eastern tip are Godin and Agrippa. Both craters appear to be deep with central peaks. The western rims appeared steeper than the eastern rims. Godin's peak looked sharper that Agrippa's peak.  

   

NOTE: The Rima is also known as the "Archer's bow." Hyginus and Rima Hyginus are east of Ukert where the "Lunar V" can be located.

C1: There is a small crater on the northern rim of Hyginus, giving the crater an almond shape. The Rima appears to enter Hyginus halfway on its east side, and splits through the lower portion of the crater. The Rima isn't continuous.

What I saw was the orientation on the left, not the usual orientation that I see on the right. Time of night or time of year perhaps have a bearing? 

   

Lyra
Time: 6:52 PM AST
Equipment: binoculars
S&T Chart: 63

Easily found Vega in Lyra using binoculars. The double-double (ε1 Lyr & ε2 Lyr) as well as δ1 Lyr and δ2 Lyr were also easily located and observed. I was also lucky enough to see ζ1 and ζ2.

Windless night with no cloud cover during the observing session. Jerry was out with his telescope for astroimaging purposes. Waxing Moon at 99.9% illumination.

C1: Hubble is east of Mare Crisium, close but not on the edge of the limb. I used Mare Anguinus and Eimmart as the start points for location as they appeared to be approximately at the same latitude. Hubble looked shallow and elongated (perhaps due to libration?). No peaks or craters visible at this illumination level.

IWLOP #103 - Reinhold & Lansberg

IWLOP #103 - Reinhold & Lansberg

Mare Cognitum, the “Known Sea,” was named in 1964 to mark the successful flight of the Ranger 7 spacecraft, which sent back the first detailed television pictures of the lunar surface. Kuiper, located in central Cognitum, is an excellent example of a small, simple crater.

Location: 3.3 N 22.8 W    Origin: Impact     Size: 48 km (Reinhold), 39 km (Lansberg)   Rukl: 31, 42     Type: Simple Crater (CS)

Objects: Reinhold, Lansberg, Luna 5 landing site

Location: Home
Date: 2020-08-28
Time: 9:02 PM ADT
Equipment: 10” Meade SCT
Eyepiece: Explore Scientific 12mm with 92° FOV
Magnification: x210
Seeing: Very Good (4)
Transparency: Very Good (4)

R1: Reinhold: deep terraces; some of the surfaces were bright which initially made me mistakenly think they were well-lit craters. Central peaks are small.
R2: Lansberg: deep terraces with 2-3 central peaks that are much larger than those in Reinhold. Lansberg slightly smaller than Reinhold.

C1: Easily located two small central peaks in Reinhold.
C2: The Luna 5 landing site was SE of Lansberg in what appeared to be a plain in a fairly rough terrain area.

IWLOP #110 - Montes Riphaeus

Picturesque mountain range located between Oceanus Procellarum and Mare Cognitum. These mountains are quite impressive when viewed near the terminator.

Location: 6-10 S 28.0 W    Origin: Impact     Length: 150 km   Rukl: 41, 42     Type: Mount

Objects: Montes Riphaeus, Euclides

R1: Montes Riphaeus is on the NW border of Mare Cognitum. It separates this Mare from Oceanus Procellarum. The mare floor on the east side of the Montes is dark compared to the ejecta to the west where Euclides is located.

Note: The rounded/curved edge of the mountains on the Mare Cognitum side made it look a bit like the remnants of an old crater. The north range also looked like it had been a crater rim.

C1: A large dome appeared SE of crater D and N-NW of the western branch of Montes Riphaeus.

No clouds and a light breeze. Because of the trees in our yard, I went to our neighbour’s driveway for an unimpeded view. Used the 12 mm eyepiece first but resorted to the 9.7 mm.

Cook looked like a very shallow crater; the sides did not provide any significant shadows. A crater appeared just inside its SW floor and there was one on its southern wall. Its floor appeared to be the same coloration as Mare Fecunditatis.

IWLOP #013b – Central Mare Fecunditatis

IWLOP #013b – Central Mare Fecunditatis

A mare consisting of two contiguous, nearly round areas of dark Basaltic lavas. The northern part is three times larger than the southern and exhibits a number of dorsa. These lavas probably overlie an impact basin of pre-Nectarian age. Mare Fecunditatis covers 20 degrees of the lunar surface and may require various terminator angles for optimum views of all the features listed below. 

Location: 4.0 S 42-62 E     Origin: Impact and Volcanism      Size: 990 km.      Rukl: 37, 48      Type: Basin

Objects: Messier, Messier A, Dorsa Cato, Taruntius, Secchi, Montes Secchi
Others Identified: Anvil

Observation 1:
Location: Home

Date: 2020-08-22
Time: 10:14 PM ADT
Equipment: 6" Dobsonian
Eyepiece: Super 25mm Wide Angle Long Eye Relief + x3 Barlow

Magnification: x144
Transparency: Good (3)
Seeing: Good (3)

R1: Messier craters very dark and shallow. Didn't see Dorsa Cato in this observing session. 
R2: Taruntius is located on the SW edge of Fecunditatis. Appeared oblong, very shallow and had a high central peak. The northern rim disappeared into the mare. Secchi is a small crater in the Montes Secchi.

C1: The coloration of the floor of Taruntius suggested possible volcanic activity, especially in light of the dark colour in the NW towards the north wall that disappeared into the Mare.

Observation 2:
Location: Home

Date: 2021-04-20
Time: 9:04 PM ADT
Equipment: 10" Meade SCT
Eyepiece: Super 25mm Wide Angle Long Eye Relief + x3 Barlow

Transparency: not recorded
Seeing: not recorded

R1: While looking for another feature, I came across Messier and Messier A. Two individual ejecta lines were very noticeable across the Mare Fecunditatis floor heading westward to end just above the crater Lubbock. Dorsa Cato was also observed east of Montes Secchi, going basically south from Taruntius towards the Messier craters. There were 3 dorsa appeared as part of the ejecta field from Taruntius: (W to E) Cato, Cushman, Cayeux.

A mare consisting of two contiguous, nearly round areas of dark Basaltic lavas. The northern part is three times larger than the southern and exhibits a number of dorsa. These lavas probably overlie an impact basin of pre-Nectarian age. Mare Fecunditatis covers 20 degrees of the lunar surface and may require various terminator angles for optimum views of all the features listed below.

Date: 2020-08-22
Time: 9:54 PM ADT
Equipment: 6" Dobsonian
Eyepiece: Super 25mm Wide Angle long eye relief + x3 Barlow

Magnification: x144
Transparency: Good (3)
Seeing: Good (3)

R2:  Goclenius appeared pear-shaped with the NE crater wall non-existent. Colombo and Colombo A also viewed with Gutenburg. Gutenburg E looked to be created by an impact that obliterated that portion of the Gutenburg's east wall. Gutenburg A impacted the outer west rim of the crater. Gutenburg C's impact obliterated the southern rim and created ejected to its south as well.

NOTE: Lighting and magnification not sufficient to complete this objective.

Observation 2:

Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm with 82° FOV + x2 Barlow
Magnification: x1060
Transparency: Excellent (5)
Seeing: Very Good (4)

R1: Lubbock located in the triangular-shaped highlands. Appeared flat, virtually no rim

C1: There were 10 ghost craters that could be seen in the immediate area of the mare floor east of Goclenius.
C2: Could not identify the rilles and clefts in the two craters at this time.

Clear skies. Enjoyed an evening observing with Jerry at home. Clouds coming in the from SSE late rent he sessions negated the ability to view Jupiter and its moons, and other objects in that area of the sky. 

Comet NEOWISE
I used α Böo (Arcturus) and ζ Böo (Mufrid) along with the line of stars from Coma Berenices and Melotte 111. It took a while to find with averted vision. I suspected it had gone past α Com. Even when I found it, I was not sure if it was the comet or one of the adjacent DSOs, but the star field I saw confirmed the comet. An email from Michael Boschat was read after I returned indoors and his photo confirmed my observation. 

Comet NEOWISE in Coma Berenices

Messier 11 (Wild Duck Cluster)
The main reason for this observing session was to view the comet. However, M11 caught my eye so I was determined to identify all the stars I used to locate the cluster. In the Scutum Star Cloud, I look for β Scutum and λ Aquila then look below them for what looks to be an upside-down and backwards golf club with a 'fuzzy' ball beside the head of the club. That fuzzy ball is M11.

Had used Arcturus and Mufrid (ζ Boötes) in conjunction with the line of stars in Coma Berenices. Averted vision was the only way to "see" the comet. No tail was obvious, but it was a round, greenish-greyish fuzzy with a dense, brighter core. I stopped mapping the star field at 11:40 PM as it had now descended into the murky horizon.

Beautiful evening. Late enough there were no mosquitoes. No clouds or wind. The 99.7% illuminated Moon affected viewing.

Jupiter
Time: 10:55 PM AST

Equipment: binoculars

Jupiter was located in essence in the centre of a broad-based triangle formed by HR 7410, HR 7327 and 50 Sgr. Saturn was about 6°-7° away from Jupiter whereas the Moon was approximately 18° away in Capricornus. Callisto and Io were very close together on one side with Europa and Ganymede close together on the other.

Comet NEOWISE
Time: 10:38 - 10:50 PM AST

NEOWISE formed a triangle with 35 Com and HR 4873. Although I could not see it in my binoculars, I knew M64 (Black Eye Galaxy) was nearby. I initially used the curve of stars in Melotte 111 but found it easier using β Com.

The comet is tracking west through Coma Berenices, moving away from the North Galactic Pole and is getting fainter every day - now at 6.5 magnitude compared to 3.2 at Roy Bishop's cottage on July 18. I'm amazed I can still see it from our back yard. We may have a few more evenings of observing it from home (fingers crossed!).

Comet NEOWISE
Boy, what a challenge it was to find NEOWISE with binoculars! Could cover 0:35 PM - 10:55 PM made it challenging to find possible pointer stars, and then there was the transparency challenge plus the 99.5% illuminated Moon. Once the clouds disappeared in the west, there was no problem. I located the curved line of stars 14 Com, 16 Com and 17 Com. I knew the comet was somewhere above this star line and had moved westerly within Coma Berenices.

Lo and behold, I found it! It was below and tot he right between 30 Com and 35 Com, almost directly below β Com. It was moving away from the North Galactic Pole (which I had just learned about from Roy Bishop). Very faint and no discernible tail. All in all, a happy observing session. May have to opt for our neighbour's yard if the comet remains visible and keeps moving west. Our shed and lilac tree are great deterrents to viewing stellar and galactic objects in the W-SW-S.

Jupiter
Callisto and Io were very close to the planet with Ganymede further out, all on the right side. Europa was on the left, about the same distance from the planet as was Ganymede. Saturn and Jupiter were also relatively close to the Moon.

Summer Triangle
Noticed the three bright stars of Aquila (Altair), Lyra (Vega) and Cygnus (Deneb). There was the Summer Triangle!

Satellites
Sitting around their bonfire, we noticed stars appearing in the wide clearing above our heads. There was also two very bright objects going across the sky - a larger brighter object that was a little higher than the smaller one following at the same rate of speed. We had just received a message that the ISS was rising. What we were witnessing was the ISS being followed by the Space X Dragon that had just left the ISS to come home!

Comet NEOWISE
Just before we left the family bonfire, we stood in their backyard away from the lights and saw NEOWISE above one of their trees adjacent to the driveway. The Moon hadn't risen enough to affect our view too much. It was still a faint fuzzy but at this point of the evening you could use direct vision to see it. 

Jupiter
Jupiter and Saturn were near the Moon. We pointed them out to William who immediately shared it with his parents. Using binoculars we could see three moons but not sure if Europa was distinguishable. 

We left to go home to get a better sense of where NEOWISE was located in our night skies. 

Canes Venatici
Time: 10:40 PM - 10:55 PM ADT

The prime reason for observing this evening was the Comet NEOWISE; however, I was also curious about the stars I saw above α CVn (Cor Caroli).

Comet NEOWISE
I used the stars in Melotte 111 to begin the search for the comet - 14 Com, 16, Com, 17 Com, 18 Com, 21 Com and 22 Com. Found it just above the triangle formed by 18 Com, 21 Com and 22 Com. AS Roy Bishop described it, "4° SE of γ Com, less than 3° from the North Galactic Pole and only 1° from NGC 4565...magnitude now near +6."

No breeze. Flies were an irritant but bug repellent worked wonders! The 92% rising Moon eventually affected seeing and transparency. Initially both were fairly good. 

Jupiter
Jupiter and Saturn were quite bright. Three of 4 Galilean moons were seen as bright pinpoints. Io was behind Jupiter; Ganymede, Europa and Callisto were to the right of the planet.

Comet NEOWISE
The comet was above Melotte 111, well below Cor Caroli and not far from γ Com. No tail was seen and, although the comet was located with direct vision at the first sighting, averted vision was required later in the evening.

The sky had been cloud-covered in the western sky but cleared near midnight. No wind. Good seeing but not sure if the Moon or high thin clouds affected the transparency.

Canes Venatici
While looking for NEOWISE, I located both α CVn and β CVN to use as pointer stars for the comet. The two stars just fit in my binocular FOV.

Comet NEOWISE 
The comet appeared as a faint fuzzy Messier-like object with no sign of a tail. It was at approximately 10° - 15° declination. There was a triangle of stars formed by HD 107053, HR4668 and HD106365 that had also been seen on July 28th. The comet had moved from the right side below this formation to its left side and was closer to Coma Berenices and Melotte 111.

Jupiter
Io very close to the planet. Callisto on one side; Io, Europa and Ganymede on the other side.

Satellite
An ever so small satellite passed below Cassiopeia from Ruchbah to Schedar before disappearing.

No wind. Thin, high clouds. It was the first time I can remember being out that late at night in shorts, t-shirt and sandals! Jerry had set up both scopes - my 10" Meade SCT for observing and his Skywatcher Esprit 120 mm aperture refractor to take photos of the Wall in the America Nebula.

Comet C/2020 F3 (NEOWISE)
With binoculars, I started with Alkaid in UMa and searched down to the horizon. Found NEOWISE just above the wiring to our house. As the evening progressed, it went down below the wire then disappeared due to poor transparency. Nucleus was very fuzzy; almost looked like a Messier object when seen through binoculars. The tail was barely observable and was considerably shorter than the night before. However, the comet did appear to be at the same declination as γ Coma Berenices. 

Also used the 10" Meade SCT with 30mm eyepiece (x83 magnification). It didn't really provide any additional information about the comet or its tail. Not sure if we will have another night in the coming week(s) to observe it again.

Jupiter
Used the Meade SCT with 30mm eyepiece to view the striping on Jupiter. Callisto was viewed by skewing the telescope slightly. The poor transparency made for poor viewing of the planet at this magnification. Also tried a x2 Barlow with a 12mm eyepiece with 90° FOV (x208 magnification) which gave me the view of the stripes.

Time: 11:35 PM
A satellite crossed West to East through my FOV across the top of the comet.

The busy star field adjacent to UMa and NEOWISE was seen on July 18, 2020 at Evangeline Beach and on July 19, 2020 on Big Muise Island at Kejimkujik National Park. It got my curiosity as to what it was but I did not take the time to investigate. It
continued to intrigue me so I decided to take some time to sketch the brightest stars I could see given the sky conditions. Coma Berenices was relatively low on the horizon so that the haze and thin cloud made for poor transparency. I used my binocs to make this observation and drawing.

I looked out our bedroom window towards the W-NW to see clear skies and stars. Got dressed, grabbed my phone and binoculars, and went into our backyard. I knew approximately where it was the previous evening, spa went looking below the Big Dipper handle. AT approximately 20° from the horizon and below Mizar-Alcor, I found a fuzzy ball with a faint tail, 2 bright stars aligned on the right and 2 at an angle left of it.

At 10:10 PM, I had looked out our bedroom window to discover most of the sky was clear so decided to take a chance at observing NEOWISE once more. I knew generally where where we had looked the night before. The cloud cover hid most of that part of the sky so that finder stars were out of the question. I didn't use SkySafariPro (needed updating). So, I searched along the lower edge of the clouds and found it!

I drew the comet (sort of) and then placed the stars around it that I could see. Then looking further away, I noticed the semi circle created by 51 Uma, 49 UMA, 47 Uma (Chalawan), HR 4264, and ω UMa. I could even make out HD 94792 and HD 944225 (not placed in the sketch) that were perpendicular to the semi-circle. I now knew where it was!

The comet had shifted a few degrees further west and was now adjacent to the rear leg of the Great Bear. It was really cool to add this location to the plot. With today being 5 months until Christmas, this felt like an early present, one you hope to see but know the chances are quite slim.

Partly cloudy and warm night. The comet was barely visible with averted vision above a curve of stars formed by 47 Uma (Chalawan), 49 Uma, 51 Uma, ω UMa, and HR 4264. The tail was greatly reduced in apparent size, perhaps only 2° - 3° in length. It was easily found and seen in 10x42 binoculars by both Jerry and me.

We had made arrangements with our daughters to camp together at a provincial park, especially when COVID-19 shut down the national park. Kathy and family arrived Monday. We arrived Tuesday. Cheryl and family arrived Wednesday. We all left the morning of Friday, July 24.

July 21: (with the Perrier family) 
No wind and the mosquitos were plentiful! Numerous fireflies were flitting and lighting the edge of the roadway. At 10:10 PM, Jerry, William, Kathy and I went out to the road at their campsite to determine if NEOWISE was visible. It was! William was so excited, he ran back to get Graham. It was the first comet for them all. We told William he would have to live a long time to see this comet again. When we told him ~ 6,800 years, he doubted if he would live that long. Smart child!

NEOWISE had again shifted further NW towards the hind leg of the Bear. The nucleus was in line with Tania Australis and Tania Borealis. It wasn't as bright as the previous two evening observations nor did it appear as long; however, it was still visible naked eye. What was really cool was the star HR 4046 that could be seen through the debris tail.

 July 21: Comet C/2020 F3 (NEOWISE)

At 10: 15 PM, Saturn was easily located naked eye but we used binoculars to determine the "slant" of the rings (or hoops as William referred to them). Could also see Jupiter and its 4 Galilean moons (Callisto & Ganymede on the left and Io and Europa on the right). William was excited to see the two planets. Saturn was smaller and seemingly less bright than Jupiter.

Magnitudes of brightness:
Saturn 0.1
Jupiter -2.7

Jupiter with its Galilean Moons & Saturn     

July 22: (with Perrier & McIver families)
Comet was fainter with a tail that appeared shorter. Because of clouds and incoming fog, the star field could not be easily seen and therefore the exact location was unknown.

At 10 PM, we noticed Saturn and Jupiter once more; they lay on the same plane as the night before. Couldn't see Jupiter's rings but could make out Jupiter's moons. Io was very close to Jupiter and almost appeared as a bulge at times versus a separate entity. Showed this to Cheryl, Kathy, Graham, Lucy and William. Note that the lines between the two planets in the sketch just indicates there is a much greater space between them than indicated.

This information was originally noted in the RASC Halifax Centre discussion List.

Just after midnight, I looked out our bedroom window to determine the status of cloud cover. Stars could be seen from the W-NW horizon all the way over to Saturn and Jupiter. Just had to go out to look for NEOWISE! Grabbed my clipboard and 10x42 image-stabilized binoculars to hopefully catch one last glimpse of the comet before it disappeared from our view.

NOTE: This comet had been discovered on March 27, 2020 and was an 18th-magnitude object located 2 AU from the Sun and 1.7 AU from the Earth. Its closest approach to Earth will occur on July 23, 2020, 01:09 UT, (3 days from now) at a distance of 0.69 AU while still in Ursa Major. It was 2nd-magnitude in mid-July.

Knowing where it had been in the previous two evenings, I began my search under the Big Dipper handle. Starting with Alcor-Mizar, I slowly made my way down towards the horizon, zigzagging short sweeps across the sky. It was about 20˚ above my horizon, nestled as it were between 57 Uma and 55 Uma on the right and slightly above the line formed by 61 Uma and HR 4536, HR 4452 and HD100235. The nucleus was very fuzzy compared to the clearly defined entity it was earlier in the week, and the tail was greatly diminished in size visually (perhaps 1˚-2˚ in length?). Location #6 now on my tracking star map for the comet!

It was 30 minutes very well spent looking at the comet and staring at the night sky to determine the star field around it. And then another 30 minutes re-sketching it with the appropriate labels for the stars observed and writing it up in my log book.

Response from Dr. Roy Bishop: Judy, there is no hope for you! Anyone who would write a report like that has been totally captured by the night sky. Normal people (99%+ of your fellow citizens) pay no heed to it. You should make an appointment with a psychiatrist.

To Dr. Roy Bishop from Dave Chapman: Anyone who has taken a peak at Judy's logbooks for Explore the Universe or Explore the Moon know that she is an Observer (with a capital O). Just don't mention Omicron2 Cygni around either of us....

Because of a dental emergency, Dave and Christine could not join us. The original weather forecast included cloud and 30% chance of rain, but we went anyway. A beautifully calm lake and easy canoe to the site. Warm sunny afternoon that clouded over. Jerry set up his camera on the beach for a time lapse (hoping) and we sat by an evening fire. Around 10 PM, we were feeling a little sleepy. Before gong to bed, Jerry checked the images being taken - there were stars! So much for going to bed!

Went out to the beach and there she was in all her glory. Visible naked eye against the starry sky. It had moved slightly NW to the other side of the Great Bear's foot. Still quite bright and about 9° - 10° in length. The ion tail was easily seen.

We were able to watch the comet for about 45 minutes before the nucleus disappeared in clouds and trees at the point of Big Muise Island. During this time, I also located Jupiter - Callisto and Europa were on one side of the planet with Io and Ganymede on the other.

Skies were clear in the morning and the winds relatively calm, making for a wonderful paddle back to Jake's Landing before heading home.

Comet: Comet C/2020 F3 (NEOWISE)
HR Stars:
Altair, HR 3603
Constellation
:
Delphinus, Ursa Major
Planet:
Jupiter + 4 Moons

Location: Evangeline Beach

Time: 8:30 PM - 11:05 PM ADT
Equipment: Binoculars 10x42 IS
Seeing: Excellent
Transparency: Good
S&T Chart: 33

Time SQM Temp
10:30 20.5 17° C
10:55 21.16 16° C

We were at Roy & Gertrude Bishop's cottage at their invitation to all who wanted to join them. COVID-spacing between observers was a requirement. Joining us were Paul Heath, Nina, Dave Lane, Mary Lou Whitehorne and 3 others. Warm night that was cloudy when we arrived at 8:30 PM but cleared beautifully for an amazing view of the skies and the Blomidon cliffs.

While looking at the comet, we also got to view other constellations and stars. Delphinus was easily found below Altair. At 10:45 PM, I located Jupiter with the binoculars. Callisto, Io and Europa were on one side (Europa close in proximity the planet) and Ganymede on the opposite side.

The comet's nucleus was inside a triangle formed by Talitha and Talitha Borealis in one of UMA's feet and HR 3603. It was at least 10° in length, stretching and filling the space between θ UMa and 18 UMa. Large Object!! We could make out the ion tail and the space between it and the debris tail. No problem locating it naked eye! We left the beach at 11:05 PM, regretfully. We gave our thanks to Roy and Gertrude for the invitation and to Gertrude for the cheese-jam cookies. 

My diagram (bottom right) is squished top to bottom but the star locations/names provide markers for a true star map (bottom left) and better perspective.

General Session - July 10, 2020 (Comet C/2020 F3 NEOWISE)

Comet: Comet C/2020 F3 (NEOWISE)
Constellations
: 
Auriga, Taurus    

Planet:
Venus

Location: Cutler Avenue, Dartmouth, NS
Date: 2020-07-10
Time: 4:05 PM - 4:40 AM ADT
Equipment: Binoculars 10x42 IS

We were at the back of a business on Cutler Avenue in Dartmouth. The original intent was to see the Comet NEOWISE but the bonus was Venus in the Hyades in the eastern morning skies. Clear skies but for very few clouds, and little if any breeze. Average seeing and transparency.

Taurus, Venus
Time: 4:05 - 4:30 AM
Equipment: Visual, Binoculars
S&T Chart: 15
Venus was about 10° above the horizon. Given the rising sun, it was impossible to discern the total star field of the Hyades, but Aldebaran and the Hyades "V" pattern was easily seen.

Venus in the Hyades/Melotte 25 in Taurus

Time: 4:34 AM
Equipment: Visual, Binoculars
S&T Chart: 12
NEOWISE had a very long, wide tail, almost 10° in length. Quite bright. Easily seen adjacent to Auriga without binoculars There were two star shapes in Auriga adjacent to the comet nucleus:
   a- an "M" shape: ψ,  ψ2,  ψ4,  ψ5,  ψ7
 
  b- a curve below the nucleus:  ψ3, 51 Aur, UU Aur

We wished we had left home an hour earlier to view it a bit longer and in brighter contrast to the morning sky.

One of my goals was to view Ophiuchus and, if possible, M10 and M12 in its centre. Success!! Both were visible in one FOV of my binoculars. 

M10 had a fairly bright central core and was obviously a compact globular cluster. It was located almost central in Ophiuchus near 30 Oph, and initially looked like a bright singular star. M12 was a little dimmer and perhaps a little larger than M10. It had a bright core with a diffuse border.

IWLOP #040 – Rupes Altai

IWLOP #040 – Rupes Altai

This incredible scarp is the continuous southwestern outer rim of the Nectaris Basin. Spectacular at low Sun, it varies from 3.5 - 4.0 km but tapers off and is more broken southward toward the crater Piccolomini and northward past crater Borda.

Location: 16-29 S30-21 E     Origin: Tectonic      Size: 480 km.      Rukl: 57, 59, 46      Type: Scarp

Objects: Rupes Altai, Cyrillus, Catharina, Colombo, Santbech, Tacitus, Kant, Hypatia
Others Identified: Ibn Rushd, Mädler, Mons Penck, Pons, Polybius

Location: Home
Date: 2020-05-28
Time: 11:16 PM ADT
Equipment: 6" Dobsonian
Eyepiece: 10mm

Magnification: x120
Seeing: Good (3)
Transparency: Good (3)   

R1:  Rupes Altai was first observed on May 28, 2020 during the waxing crescent phase when it was well-lit. It was again observed on March 21, 2021 during the 1st Quarter when observing Piccolomini (IWLOP #031 – Piccolomini).
R2: The ridge between Cyrillus and Catharina is rugged in appearance and continuous. The ridge between Colombo and Santbech is broken by a smoother ridge below Colombo with a well worn crater and flood plain (?) closer to Santbech.

C1: Tacitus, Kant and Hypatia were located. Altai Scarp appeared continuous in the SE portion but appeared worn/non-existent as it continued N towards Tacitus, Kant and Hypatia.

Note: Rupes Altai was first noticed because of the well-lit Altai Scarp; it wasn't in shadow.

IWLOP #047 - Delambre

IWLOP #047 - Delambre

Delambre is located near the edge of Mare Tranquilitatis and not too far from Statio Tranquilitatis. Note the sharp rim and terraced walls of Delambre. Try to see this crater at a high sun angle.

Location: 1.9 S 17.5 E     Origin: Impact      Size: 52 km     Rukl: 46      Type: Complex Crater (CC)

Objects: Delambre, Theon Junior, Theon Senior, Delambre D, Apollo 11 landing site

Equipment: 6" Dobsonian
Eyepiece: Meade Super Plössl 9.7mm + x2 Barlow

Magnification: x250
Seeing: Good (3)
Transparency: Very Good (4)  

R1:  Delambre - Located the 1969 Apollo 11 landing site above Rimae Hypatia and NW of Moltke on Mare Tranquilitatis. The Mare floor looked very flat and smooth at this magnification for the Apollo landing.
R2: The twin craters Theon Junior and Theon Senior were easily located west of Delambre. Both are deep, round, and are much smaller than Delambre. Shadows covered their crater floors.

C1: Delambre D was located on the north wall of Delambre. It appeared more as a slight bump to the otherwise smooth roundness, as well as only see a slight discolouration at this location. One wall of Delambre H and part of the crater floor were barely visible just outside Delambre's NW wall, between Delambre and Theon Senior.

R1: Petavius quite a large crater with a very large and irregularly shaped central peak.
R2: Rimae Petavius was very evident and easily identified. It went basically across the crater from the central peak (refer to sketch).
R3: Wrottesley appears to be NW to or on the outer part of Petavius's wall and has a faint central peak. It's not as terraced as Petavius. The shadow on its SE wall seems to extend outwards from the crater - perhaps from ejecta (?). 

C1: I was very excited to see how easily Rimae Petavius could be seen. I followed it to the inner eastern rim and out the south wall. 
C2: Noticed dark materials at 1 and 5 o'clock on the crater floor.
C3: Rimae Petavius continued southward until it met with the crater Hase (refer to sketch).

IWLOP #024 – Atlas & Hercules

Two prominent craters that share the same region. There is some debate about the age of Atlas but it is probably Upper Imbrium while Hercules is Eratosthenian.

Location: 46.7 N 44.4 E     Origin: Impact      Size: 69 km      Rukl: 15, 14     Type: Complex Crater (CC)

R1: Both Atlas and Hercules appear oval. Atlas is much shallower than Hercules, perhaps due to the infilling as suggested in the IWLOP notes.
R2: Atlas has terraced walls, especially in the southern area where it almost appears to flatten as it approaches the floor.

C1: Hercules G was found in the brighter southern Hercules floor.
C2: Hercules walls were high with multiple terraces. The SE of the crater floor was noticeably darker than the rest of the floor.
C3: Multiple central hills in Atlas could be seen quite well. Could see a hint of 3 of the 5 of the south rilles. A portion of the north crater floor appeared darker. Southern wall may be more terraced than the northern portions.

Equipment: 6" Dobsonian
Eyepiece: Meade Super Plössl 9.7mm + x2 Barlow

Magnification: x250
Seeing: Very Good (4) 
Transparency: Good (3) 

R1:  Lacus Mortis is west and adjacent to Atlas and Hercules. Looked to be an old crater perhaps(?).
R2: Bürg had steep sides that created long shadows over the central peaks.
R3: Plana had as deep thick east wall but the west wall seemed disintegrated. Plana joined to Mason. Mason's north wall was virtually non-existent; another mountain on its E-SE wall. Plana had a central peak; Mason did not. Both seemed to form the southern border of Lacus Mortis.

C1: Rimae Burg began where shadows showed on the west side of Lacus Mortis and headed NE above Bürg.

Moon
Planets:
 
Jupiter, Mars, Saturn

Conjunction: Moon-Jupiter-Saturn-Mars
Constellations: Lyra
Stars: Nunki, Vega, ε1 Lyrae, ε2 Lyrae, ζ Lyrae

Location: Home

Date: 2020-03-18
Time: 6:30 AM - 7:00 AM AST
Equipment: Visual, 10x42 IS Binoculars
Temperature: 0° C
SQM: 14.63 (with Sun just below the horizon)

Jerry woke me up at 6:30 AM AST to alert me of the Moon-Mars-Jupiter-Saturn conjunction in the Eastern sky. Dave Chapman had tweeted it was "up". Clear skies in the East, very light breeze, and no clouds. 

Conjunction
Could easily see the Moon with the reddish Mars at 1 o'clock from the Moon's terminator. Jupiter was at 11 o'clock. Saturn was quite a distance away towards the SE. Using my binoculars, I could see a star that I later identified as Nunki in the handle of the Teapot. 

Jupiter, Mars and Saturn were easily seen naked eye and with binoculars. I did not take the time to locate and identify Jupiter's moons. Saturn was seen between two branches of our maple trees.

On the Moon, could easily see Kepler and its splatter, Copernicus on the terminator, Aristarchus brightly lit and Montes Jures well lit on the northern shore of Sinus Iridum. Oceanus Procellarum made up most of the lit portion of the Moon look dark.

Conjunction of Moon-Mars-Jupiter

Proximities of the Moon and 3 Planets

Big Dipper Asterism in Ursa Major, Ursa Minor
Time: 7:45 PM
Equipment: Visual
S&T Chart: 31, 32, 33, 43, F
The Big Dipper was in essence standing upright with its bowl facing W-SW. All 7 stars were visible naked eye.
The Ursa Minor 'bowl' was below Polaris as it was two nights ago. I could locate 5 of the 7 stars - Anwar al Farkadain and Alifa al Farkadain (the two stars closest to the handle) were barely visible at 10:30 PM due to diminished sky conditions. 

Orion, M42, M43
Time: 8:17 PM
Equipment: Visual, Binocular
S&T Chart: 14, 16, B
Easily located all the major stars and nebula in Orion. Could easily see M42, M43 and NGC 1981 in Orion's 'sword' below his belt naked eye. I also used my binoculars to have a closer look. I used the 16" Dob that had been poorly aligned so had to slew to find M42 and M43.

M42 (Orion Nebula) was located naked eye and with binoculars. However, it filled the Dobsonian FOV! There were 3 stars in a triangular formation (very tight) and 3 more in a linear arrangement. The "wings" spread from side to side; there were 3 very bright stars in the nebulosity and a couple just outside where the triangular star formation was located. All in all, very impressive.

Also refer to Messier Catalogue - M042 (Orion Nebula, NGC 1976) - February 23, 2020.

     M42   
   M43 

M43 (De Mairan's Nebula) was located naked eye and with binoculars. In the eyepiece of the Dobsonian, the nebulosity was like half of a ball with a very bright star about half way along the "cut" edge. There were 4 stars just outside the rounded edge that were bright.

Also refer to Messier Catalogue - M043 (De Mairan's Nebula, NGC 1982) - February 23, 2020

Otherwise, Orion took up a large part of the southern sky and we watched him over the course of the evening go from S-SE to S-SW. M42

Taurus, Hyades/Melotte 25, Cetus, Venus
Time: 8:35 PM
Equipment: Visual, Binocular, Telescope
S&T Chart: 14, 15, A
Identified Aldebaran and the V-shaped open cluster of the Hyades naked eye. Also used binoculars to view the gorgeous Hyades! Attempted to find M1 (Crab Nebula) near ζ Tauri but could not find it naked eye, with binoculars, nor the 16" Dobsonian.
To locate Cetus, I followed down from the Hyades to λ and ξ to Cetus's head and there found Mira.
The very bright Venus was high in the sky, west of Cetus in Pisces.

Lepus, M79
Time: 9:23 PM
Equipment: Binocular, Telescope with 40mm Plössl eyepiece
S&T Chart: 16
Lepus was easily located naked eye below Orion and was able to identify all the major stars of the constellation. With binoculars, used Arneb and Nihal as the stars to measure distances; they were approximately 1 FOV apart in my binoculars. Went 1 FOV below Nihal and located M79 - a small dense cluster that had a circle of stars around it. 

I then used the 16" Dobsonian, slewing from M43 to M79. Found a small compact grey fuzzy with a bright centre and a nebulous-looking but probably stars are packed around the central core. What made this so interesting (and gave me an "oh wow" moment) was the darkness surrounding this nebula that was ringed with 8-9 bright Gaia-labelled** stars, just like a stellar outline of the space taken by the cluster. Really cool! Also refer to Messier Catalogue - M079 (NGC 1904) - February 23, 2020.

M79 and the its location near the Constellation Lepus

** Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia provides unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group. This amounts to about 1 per cent of the Galactic stellar population.

Monoceros, M50
Time: 9:45 PM
Equipment: binoculars, 16" Dobsonian
S&T Chart: 25, 27, E
I was using the Dobsonian to locate these two objects, despite its poor polar alignment. Used the controller to move around this area of the sky but to no avail. The seeing had greatly diminished at this point so did not make an attempt to identify the stars in the constellation nor to locate M50 via Canis Major.

Canis Major, M41/Little Beehive
Time: 9:50 PM
Equipment: Visual, Binocular
S&T Chart: 27
The temperature had dropped to -4° C and was cool but the breeze had dropped. Stars of the 'big dog' were as evident as they were two nights ago but they were not as bright. Used my binoculars to very easily locate M41.

                       Leo
Leo
Time: 10:00 PM
Equipment: Visual
S&T Chart: 34, 35
I could actually see the major stars in the constellation. This was helpful as I was attempting to locate 5 Messier objects in Leo: M65 and M66 between Chertan and Iota; M95, M96 and M105 just under Leo's mid-belly. Unfortunately, at this time of the evening, the seeing had diminished. Could not find them naked eye with the binoculars over a 30-45 minute period, nor the 16" Dobsonian with 40mm Plössl eyepiece. Disappointing to say the least.

 

Cassiopeia, Perseus
Time: 10:20 PM
Equipment: Visual, binoculars, telescope
S&T Chart (Cassiopeia): 1, 3, 72
S&T Chart (Perseus): 2, 13

The seeing and transparency had diminished; stars not quite as bright as compared to what they were earlier. The constellation was identifiable since 8:00 PM or so. I wanted to look for M52 and M103 using binoculars and the telescope. Unsuccessful on both counts.
Located Perseus and many of its stars. However, due to diminishing seeing and visibility, could not locate NGC 869 / NGC 884.

Winter Circle, Winter Triangle
Equipment: Visual
The Winter Circle stars were quite visible all evening - Capella, Aldebaran, Rigel, Sirius, Procyon, Pollux and Castor.
The Winter Triangle Stars were also visible all evening - Procyon, Sirius and Betelgeuse.

Originally viewed this with binoculars.

I then switched to the 16" Dobsonian. Given the star alignment was not the best, I had to star hop to M42/M43. the Dobsonian to M42. I could make out what looked like wings of nebulosity. There were two groupings of 3 stars visible - one set tight together in a triangle while the other 3 were linearly arranged.

M42/M43 easily located naked eye.

Lepus was well above the horizon and all the stars could be seen. I tried to use 10x42 IS binoculars but failed to see it. Dave Chapman had shown me this earlier in the observing session so I decided to try the telescope on my own.

Arneb and Nihal were used as locator stars and M79 was found below Nihal. The globular cluster had a very dense core and an amazing circle of stars around it. Really Cool!

NOTE:
The stars encircling the core that I observed have GAIA/TYC designations.

Taurus, Melotte 25/Hyades, M45/Pleiades
Time: 7:55 PM
Equipment: Visual, Binoculars
S&T Chart: 14, 15, A
Identified Aldebaran and the Hyades naked eye. Used binoculars to view the Hyades in more detail - beautiful!
The Pleaides was quite high in the sky and easily located adjacent to Taurus. All major stars in their nebulosity could be identified.

Ursa Major, Ursa Minor
Time: 8:00 PM - 8:10 PM
Equipment: Visual, Binoculars
S&T Chart: 32, 33, 41, 51
The Big Dipper was in essence upright; all 7 stars were clearly visible naked eye. I used the binoculars to view the double stars Mizar and Alcor. The Little Dipper bowl was below Polaris whereas at other times of the year it is above. For the first time in many years, I could see all 7 stars of the little dipper!! First time observing since having cataract surgery.

 

Big Dipper in Ursa Major

Venus, Cetus, Pisces
Time: 8:10 PM - 8:30 PM
Equipment: Visual, Binoculars
S&T Chart: 4, 6, 7
Venus was certainly bright as it obliterated stars in the low SW horizon.

To locate Cetus, I went down from the Hyades to  λ Ceti and ξ Ceti to Cetus' head and from there found Mira. Mira was about 25° - 30° above the S-SW horizon. Could easily locate Menkar, γ Ceti, ξ Ceti, μ Ceti, λ Ceti and δ Ceti. Cetus was virtually vertical. Could not compare it to any stars in Aquarius (it was below the horizon). Ο Ceti/Mira did appear dimmer than Alrescha. 

I was attempting to determine the brightness of Mira when I saw a star adjacent to it. Identified it as α Pisces (Alrescha)) then proceeded to locate and identify as many of Pisces stars before the west side disappeared in the trees. I determined Mira was dimmer than Alrescha but that may have been because it was at the same declination (approximately) as Venus.  

                                                                                                                    Pisces

Winter Circle, Auriga, Gemini, M35
Time: 9:00 PM - 9:10 PM
Equipment: Visual
S&T Chart: 12
All of the Winter Circle stars were located and identified - Capella, Aldebaran, Rigel, Sirius, Procyon, Pollux, Castor. Noticed Auriga and its formation; Capella was quite bright compared to the others in this constellation.
Castor and Pollux were also easily found. A while later, their 'arms', 'body' and 'legs' were identified. I pointed out that M35 was at Castor' s foot/toe near the star Propus. 

Orion
Time: 9:15 PM
Equipment: Binoculars
S&T Chart: 14, 16, B
Could see M42 naked eye but used my binoculars to view M42, M43 and NGC 1981 in Orion's sword. The nebulosity spreading around a bright central area was evidenced. Orion took up a large portion of the southern sky and we watched him over the course of the evening go from S-SE to S-SW.

M41 (Little Beehive)
Time: 9:40 PM
Equipment: Binoculars
S&T Chart: 27
I was beginning my search for M47 and with Sirius at 12 o'clock in my FOV, a cluster of stars were at 6 o'clock. Used SkySafaariPro to identify it as open cluster M41.
There seemed to be a line of 4 stars, brighter than the others, that were best seen with averted vision. A much brighter star was located just outside the circular centre of the cluster.

                               M47
M47 (NGC 2422)
Time: 9:50 PM
Equipment: Binocular
S&T Chart: 26, 27
Had to wait for Sirius and Procyon to clear the SE treeline. Using Sirius as the start point at 3 o'clock in my binocular FOV, I went 2 FOVs east of Sirius to find M47. The 4 brightest stars of its core stood out, then was able to sketch details, despite the bitter cold. Also refer to Messier Catalogue - M047 (NGC 2422) - February 21, 2020

Canis Major, Canis Minor
Time: 10:00 PM
Equipment: Visual
S&T Chart: 4
I was pointing out Lepus to Troy Sweeney and we both noticed the "dog" in the sky. Without identifying any stars except Sirius, we could see the body, legs, head and tail of this mythical heavenly creature. Had never seen this so clearly before. Quite striking. 
Procyon and Gomeisa of Canis Minor were were easily found.

Aries
Time: 10:30 PM
Equipment: Visual
S&T Chart: 4
I was looking in the area of Pisces and Cetus and saw the 4 stars of Aries in a vertical line. Using SkySafari, I identified them as Aries. All very clear and pinpoint bright.

Perseus, NGC 869/NGC 884
Time: 11:35 PM
Equipment: Visual
S&T Chart: 2, 13
Troy and I noticed an arc of stars that pointed to Cassiopeia and determined it was the arm shoulder and head of Perseus. The stars in Perseus's arm were wrote brilliant and the arc it created easily recognizable.  I noticed a nebulosity between η Per (Miram) and Ruchbah & Begin of Cassiopeia. Using Sky SafariPro realized the double cluster 869/884 were part of the nebulous oval. There was a dark lane per se between the double cluster and the Heart & Soul Nebulae.

Heart Nebula/IC 1805 and Soul Nebula / IC1848
Time: 11:40 PM
Equipment: Visual, Binoculars
S&T Chart: 1, 2, 11, 13
Found an oval of stars adjacent to NGC 869/NGC 884. Above it were two nebulous entities that I viewed with mu binoculars.

The Heart Nebula was squarish in appearance but had a part that seemed brighter than the rest. I was very excited to find this! Could not make out any specific stars int he Nebula.

The Soul Nebula was 'above' the Heart Nebula. It appeared as a squared oval with a slightly brighter area on its west side. Could not make out any specific stars.

Jerry and I were together at SCO. He was imaging the Bubble Nebula and I was there for General Observing. There was no cloud or wind and the humidity was low. It became much cooler as the night progressed but the skies also became darker.

Summer Triangle
Time: 7:05 PM
Equipment: Visual
Identified the Summer Triangle very quickly. Vega was located, then Altair near the zenith, then followed a while later with Deneb. These three stars were certainly visible until at least midnight (after that, my attention was elsewhere). Its as interesting to note that this was still high in the sky as the Winter Circle was rising in the SE (could not see Procyon and Sirius).

Milky Way, Cygnus
Time: 7:15 PM
Equipment: Visual
S&T Chart: 62
The Milky Way started to make its presence known. Hints of the dark lane and its adjacent star fields were just starting to form. Seeing the Teapot gave a clue as to where it began in the southern skies. Looking up, there were clues as to where it lay, shading and light sections were barely discernible but so awe inspiring. The start of another glorious night under the strs with Jerry!

I then looked at the Sagittarius Star Cloud in the Milky Way by finding the two stars ζ Sputum and β Sputum. Knowing their location, I was then able to find M11 (Wild Duck Cluster) - the fuzzy ball at the end of the golf club.

I looked more closely at the stars of Cygnus. Easily found were Deneb, Sadr, Albireo, ι Cygni, ζ Cygni, ν Cygni and δ Cygni. The "Northern Cross" was easily seen, even the blueness of Albireo could be discovered naked eye. 

Jupiter
Time: 7:20PM
Equipment: Visual, Binoculars
The very bright Jupiter was found visually. Using the binoculars, could easily see 3 of the moons, two quite clearly but not the one in the SW. After checking with SkySafariPro, I realized the reason the one in the SW appeared blurred or elongated was because Ganymede and Callisto were so close it appeared as one.

Scorpius, Ophiuchus
Time: 7:25PM
Equipment: Visual
S&T Chart: 54, 56, 58
Noticed that Antares and other stars of Scorpius were already below the horizon/trees in the SW. Quickly identified Ophiuchus's "base" stars - Sabik, ζ Oph, and Yes Prior. Once they were found, the rest of the constellation was easily seen. The part known as Serpens Caput couldn't be seen due to the angle of the constellation and the tree line, but Serpens Cauda's stars were readily found.

Satellite
Time: 7:30 PM:
Equipment: Visual, Binoculars
A bright consistent object caught my eye as it travelled from Mirach in Andromeda in the East to where it disappeared just past ψ Capricornus. Used binoculars to determine if it was the ISS; I assumed it was.

 

 

 

The Teapot & Saturn

Teapot, Saturn, M8, M20, M21, M22, M28
Time: 7:35 PM - 7:51 PM
Equipment: Visual, Binoculars
S&T Chart: 69 
a) Using the Teapot spout, found M8 (Lagoon Nebula) with my binoculars. The line of bright stars in a nebulous oval gave it away. Also had M20 (the Triffid) in the same FOV; it appeared as a round fuzzy with some central brightness. The open cluster M21 was easily seen in the same FOV as M20. It appeared to have numerous stars centrally and was quite open as a cluster, almost indiscernible from the star field around it.
b) Using the lid (Kaus Borealis) as the start point visually/naked eye. Used my binoculars to locate that star, went 30° to a Y-shaped star formation then found the round fuzzy of globular cluster M22. Its core was bright compared to its edges. I then used the lid star and looked up to the right to find the small grey fuzzy M28.
c) Having found other Messier objects around the Teapot, I also located M23. The open cluster was quite bright.

Then noticed Saturn (not as bright as Jupiter) and reflected beautifully in the mirror-like pond in front of the Observatory. The Teapot was beginning to sink below the SW horizon, making Ptolomy's Cluster impossible to observe. Saturn was right above Nunki in the Teapot's handle. 

Perseus, Melotte 20
Time: 8:05 PM
S&T Chart: 2, 13
Perseus was quite high in the sky throughout the whole session so had time to view it. Using Naked eye, I could find the 4 stars with which to compare Algol for magnitude (Adid Australis, Adid Borealis, Misam and Andromeda's Almach). I did a second comparison at 11:55 PM and at 12:51 AM (no record). 

Mirfak was easily seen naked eye so then used my binoculars to get a closer view of it and Melotte 20. So many gloriously bright stars, making it one of my favourite open clusters. Unfortunately, the sky was getting poorer as fog began to encroach on our view. 

Lyra
Time: 10:01 PM
Equipment: Visual, Binoculars
S&T Chart: 63
I paid closer attention to Lyra that at this time looked like it was lying on its side. Used Vega to locate Epsilon1 and Epsilon2 that were one above the other. Delta1 and Delta2 were also observed; although side by side, the former was smaller and just slightly higher.

             

Lyra

Meteor
Time:10:05 PM
Equipment: Visual
A meteor shot across the southern sky. It crossed the top of Capricornus but inside the upper "bowl", travelling from Deneb Algedi to Algedi.

Hyades
Time: 10:30 PM
Equipment: Visual, binoculars
S&T Chart: 15
The stars were so vivid so decided to sketch the Hyades aka Melotte 25 or Caldwell 41 or Collinder 50. I put my binoculars on a tripod in the observatory and began to sketch, beginning with Aldebaran then worked my way around the Bull's head. Thoroughly enjoyed this exercise.

        Aldebaran and the Hyades / Melotte 25
The Pleiades / M45

Pleaides
Time: 10:40 PM
Equipment: Visual, binoculars
S&T Chart: 15
The Pleiades were directly above the Hyades and they were so bright I decided to sketch them. My binoculars were still on the tripod; it took about 25 minutes to sketch this. Some areas intrigued me, such as:
  a)
the 6 stars below Alcyone and Merope
  b)
the curve of stars below Atlas and Pleione

Cetus
Time: 11:05 PM
Equipment: Visual, Binoculars
The was the first time Cetus was (1) above any horizon previously observed and (2) sought out and found! Wanted to find it for the ETU observation of Mira (ο Ceti).

WOW! Is Cetus ever large! Come to find out it's the 4th largest constellation in the sky, covering an area of 1231 square degrees. All of the stars drawn were seen naked eye in the E-SE of our SCO sky. At 11:05 PM, Mira looked comparable to Menkar and was brighter than α Pisces (Alrescha).

Comparative Magnification:

4.9   Mira        
4.1   δ Ceti
3.8  α Pisces
2.54 Menkar

Cetus

Uranus
Time: 11:15 PM
Equipment: Visual, Binoculars
In using my binoculars to look around the area between Cetus and Aquarius, I accidentally discovered a blue object between Mira and α Aquarii - Uranus! This blue object appeared in the star-laden patch of sky and it looked out of place/odd. It was 6° up and to the right of ξ2 in Cetus and approximately 6° due east of ο Piscium. Having located the planet in Pisces, it was very easy to see it naked eye.

 

  Uranus (between Cetus and Pisces)

Gemini, M35
Time: 11:50 PM
Equipment: Binoculars
S&T Chart: 25
We stepped out into the parking lot to look E-SE. Gemini was lying on its side parallel to the horizon. Could make out Castor, Pollux, λ Gem and θ Gem but the legs were more difficult to locate.  Because I was searching for M35 (Shoe Buckle Cluster), I resisted and found Propus and the adjacent stars in his foot. Using my binoculars, M35 appeared as a round grey fuzzy. The open cluster did not appear to have any area brighter than another; it was diffusely lit.

M35 (location in Gemini)

Auriga, M36, M37, M38
Time: 11:55 PM
Equipment: binoculars
S&T Chart: 12
In Auriga, Capella was quite bright. M36, M37 and M38 were three of my objectives and I knew they were in a line basically perpendicular to θ Aur and Elnath. They were relatively quickly located, then I set out to look at each a bit more closely. 
   a) M36 was located above the line formed by the stars and was a very bright roundish grey shape.
   b) M37 appeared as round grey fuzzy about halfway between θ Aur and Elnath. It was not as bright as M36 but it did have a central brightness compared to its outer edge.
   c) M38 was found in the same FOV as M36. Could not see any individual bright areas or a concentrated one - just a round grey fuzzy.

Leaping Minnow Asterism
Time: 11:58 PM
Equipment: binoculars
S&T Chart: 12
All of Auriga's stars could be seen along with hints of the Messiers and the Leaping Minnow.
I used my binoculars to have a closer look at the Messiers and the Leaping Minnow. Used some time to better determine how to explain to Jerry where the Leaping Minnow was located and what he should see through the binoculars. There were 3 pairs of stars near β Tau (Elnath) - 14 Aur, 16 Aur, 17 Aur, 19 Aur; the latter three had an unnamed adjacent star. I was very happy that Dave Chapman showed me this asterism about 2 years ago.

Leaping Minnow asterism in Auriga

5 Meteors
Time: 11:00 PM - Midnight
Equipment: Visual
Jerry and I saw 5 meteors. Four radiated out of Auriga heading towards Gemini and the Lynx. The fifth on left Cassiopeia to head towards Perseus.
Around midnight, I used Deneb and ν Cygni as markers to attempt to find the North America Nebula. I saw a dark area but could not make out the shape.

Winter Circle, Orion, M42, M43
Time: 12:05 AM & 1:45 AM
Equipment: Visual, Binoculars
12:05 AM - Because Capella and Aldebaran had been viewed earlier, I decided to see if the stars of the Winter Circle were all there. Not to be. Canis Major (with Sirius) and Canis Minor (with Procyon) had not yet risen above the horizon. Decided to look for Orion as part of my search for the Winter Circle. Did see all the major stars of Orion and used my binoculars to view M42 and M43. Much better view than just naked eye!
1:45 AM - As we were leaving, the Winter Circle was all there! Sirius had just come above the SE horizon! Really strange seeing both the Summer Triangle and the Winter Circle in the sky on the same night - never experienced this before.

Upper section of Orion with his shield

Kemble's Cascade
Time: 12:10 AM
Equipment: Visual, Binoculars
S&T Chart: 11
Did not look for Kemble's Cascade until after midnight when Cassiopeia was high enough in the sky to locate this. Although actually located in Cameliopardis, Cassiopeia is used to find it. The line of stars in the Cascade were easily seen naked eye, and NGC 1502 at its end was truly bright. Melody Hamilton would be proud of my purposefully seeking out and finding one of her favourites!

Observing with grandson William who was with us for a sleepover. We spent some time going through some the constellations and asterisms he knew. For instance, because Vega was one of the first stars to be seen, he could easily find the Summer Triangle, and we saw the beginnings of the Milky Way showing up.

He has known about the Big Dipper since he was little. He also remembered Cassiopeia that he first saw at Blomidon Provincial Park two years ago (although he calls it the "William" constellation because of its 'W' shape). He was also shown the double stars Mizar and Alcor at Blomidon and during this evening's sky tour.

Clear skies, no clouds and virtually no wind with only an occasional breeze. General observing with Jerry, Blair MacDonald and Mark Dryden - the fellows with telescopes and me with binoculars. The southern horizon became more diffuse as the night wore on.

Pisces Austrinus
Time: 11:00 PM - 2:30 AM
Equipment: Visual
S&T Chart Reference: 76, 77, 78, 79
Fomalhaut was the star that caught my attention (as per usual) so was able to also identify the following Pisces Austrini stars - ε, η, θ, ι, μ, β and δ. I'm always excited to see what is considered to be a "southern constellation" in my northern skies!

Taurus + Hyades/Melotte 25
Time: 11:50 PM
Equipment: Visual + Binoculars 
S&T Chart Reference: 14, 15
Located Taurus because of the brightness of Aldebaran and the nearby Pleaides. Using the binoculars, I looked more closely at the open cluster Hyades. What a lovely open cluster on such a beautiful night. I did not sketch it this evening. Just enjoyed viewing it.

M45 / Pleiades
Time: 11:02 PM + 11:51 PM
Equipment: Visual + Binoculars 
S&T Chart Reference: 14, 15
I took the time to sketch the Pleiades star field.

There was a line of stars arching away from one of the nebula in the cluster. The stars were of varying brightness but were very clearly visible. The nebulosity around each of the primary stars were easily seen with binoculars.

   

NGC 869 + NGC 884
Time: 11:30 PM
Equipment: Binoculars 
S&T Chart Reference: 2, 13
I located the double cluster in Perseus near η Perseii. Both NGCs were very diffuse grey fuzzies with a denser and brighter core.

Summer Triangle / DAVe
Time: 11:55 PM
Equipment: Visual + Binoculars 
The 3 stars in the Triangle - Deneb, Altair and Vega - were easily located naked eye. Their related constellations - Cygnus, Aquila, Lyra - were easily picked out against the dark sky.

Ophiuchus, Serpens Caput
Time: 12:05 AM
Equipment: Visual
S&T Chart Reference: 54, 56, 64, 65, 67
Ophiuchus was initially identified from the large curve forming the bottom of what I refer to as his cape but others may refer to it as part of the constellation Serpens. The snake's head (Serpens Caput) was very easily located and identified.

Perseus + Melotte 20/α Persei Cluster/Perseus OB3 Association
Time: 12:55 AM
Equipment: Visual + Binoculars 
S&T Chart Reference: 2, 13
The triangular peak of Perseus was easily located. Mirfak and Melotte 20 were seen through the binoculars. Love Melotte 20!
Also viewed were Algol, ε Perseii, and κ Perseii. Algol was at minimum earlier in the day so could not see the star brighten over time.

Auriga
M36 / Pinwheel Cluster
M37 / NGC 2099
M38 (Starfish Cluster)
Time: 12:55 AM
Equipment: Visual + Binoculars 
S&T Chart Reference: 12
Visually found Auriga in the NE sky above Gemini.

M37 was found just a bit southwest of the imaginery line between Elnath (beta Aurigae) and theta Aurigae.

M36 was found northeast of M37, just about equidistant on the other side of the imaginery line. M36 and M37 could be seen in the same FOV.

M38 was found northeast of M36. Both of these objects could be seen in the same FOV.

Gemini + M35
Time: 12:58 AM
Equipment: Visual
S&T Chart Reference: 23, 25
Castor and Pollux appeared above the horizon lying on their side in the NE sky. I followed Castor's body to his toe (1 Gem) to view the small grey fuzzy M35.

Capricornus
Time: 1:15 AM
Equipment: Visual + Binoculars 
S&T Chart Reference: 66, 68, 77
The "smile in the sky" was located and identified; all of its brightest stars were found visually. Algedi Prima (α1 Capricorni) and Algedi Secondi (α2 Capricorni) were easily seen as separate entities. Dabih Major (β1 Capricorni) and Dabih Minor (β2 Capricorni) were also seen.

M30
Time: 1:28 AM
Equipment: Binoculars 
S&T Chart Reference: 77
I purposefully set out to find this DSO. I used SkySafariPro to locate it and the stars around it. With binoculars, I first found Dabih Minor (β2 Capricorni) then ζ Capricorni. I then went about 3º away and found the cluster. 41 Cap was at 10 o'clock to M30 and was fairly faint compared to 41 Cap.

NGC 7293 / Helix Nebula (attempt to find)
Time: 1:30 AM
Equipment: Binoculars 
S&T Chart Reference: 76, 77
This was the first attempt to find this. Having found Pisces Austrinus, this DSO was about 12º above Fomalhaut and ε Pisces Austrini. It looked to be about the same magnitude as M30.  Couldn't find this at this time. May not have looked high enough towards Aquarius.

M34
Time: 1:45 AM
Equipment: Binoculars 
S&T Chart Reference: 2, 13
Found this open cluster using the Observatory's 16" Dobsonian. It had 6-7 central bright stars. It also appeared to have a ring of stars around the object as if it were a container. Also refer to Messier Catalogue - M034 (NGC 1039) - September 28, 2019

 

NGC7293 - Location in Aquarius
M34

 

M2 (Globular Cluster)
Time: 2:04 AM
Equipment: Binoculars 
S&T Chart Reference: 75, 77
This was my first attempt to find M2. With binoculars, it was nothing more than a grey fuzzy. 

I located Aquarius, specifically looking for Sadalsud (β Aquaria). From there, I looked for a backwards & upsidedown "L" shape of 3x3 stars. When found, I looked for something like of bell curve of stars at 2 o'clock to the 3x3. When found, M2 was 2º away.

When I returned home, I was able to label the stars in these two formations.

I along with Tony Schellinck, Paul Heath, Melody Hamilton and a group of others noticed the strange arrangement of the 4 Galilean moons - like butterfly wings. I made rough notes about this but couldn't find this particular lunar formation; the OH had no mention of it and SkySafariPro showed the moons in a line with Europa on one side and Io, Ganymede and Callisto on the other.

No explanation for this pattern. Perhaps Europa (upper right of the 4 sketched) formed the shape with three GAIA-designated stars and we didn't look further for the other 3 moons (?).

Date: 2019/08/12-13
Time: 9:30 PM - 12:20 AM EDT
Equipment: Visual + 10x42 IS binoculars

First found this with Melody Hamilton and Dave Chapman. Very clear night, dew starting to form. The comet was found two ways:

a) Melody:
Visually found NGC869/NGC 884. With them in my lower binocular FOV, I looked for a "7" laying down on its side, then looked up from the the left side of my FOV at about 10 o'clock. There it was ! Including a slight tail.

b) Dave:
Look at Cassiopeia's star Segin (epsilon Cass). With Segin centred on my FOV, 21P could be found at approximately 8 o'clock.

Win-win! Two ways to find the same location. After I returned home, I identified the four stars in the "7" lying down.

No breeze or clouds. 

Moon
Time: Not recorded
Equipment: Binoculars 
Using the binoculars, I identified the distinct mountains on the north shore of Mare Imbrium (Montes Alpes) and Sinus Iridum (Jura Mountains). Tycho was seen quite well as was its ejecta field all the way up to Mare Serenitatis. 

Jupiter (in Scorpius)
Time: 10:34 PM ADT
Equipment: Binoculars 
Viewed Jupiter and its moons while standing between two apartment buildings to block as much street and Moon light as possible.

Clearly identified Europa and Callisto. Io and Ganymede were not seen. SkySafariPro suggested Io was very close to the Moon's west limb but I couldn't separate the moon from the planet. Ganymede must have been occulted by the planet.

   

Saturn (in Sagittarius)
Time: 10:34 PM ADT
Equipment: Binoculars 
Stood between the two apartment buildings to prevent as much street and Moon light as possible from interfering with this observation. Only the brightest and perhaps larger stars could be seen. Some stars of Sagittarius were easily seen - χ1 and χ2, ν1 and ν2. 

Could also see Saturn's moon Phoebe! Initially mistook Albaldah (π Sgr) and ο Sgr as possibly 2 of its moons.

   

Meteor (from Perseids)
Time: ~ 11:00 PM ADT
Equipment: Visual
Long streak approximately 1 second in duration that travelled from the centre of the Summer Triangle towards the Moon. The apartment building blocked the view of its origin. Turned colour from red to green. Tail was very short.

Summer Triangle / DAVe
Time: Not recorded
Equipment: Visual
Despite the Moon and street lights, I could see Altair (in Aquila), Deneb (in Cygnus) and Vega (in Lyra).

No breeze and very few clouds. Attending JamFest 2019 in honour of my brother, Randy, who had died on January 31, 2018. Stood on their dock to get a good view of the

Lunar Observations
83.4% Moon. Easily located Mares Crisium, Imbrium, Serenititatis, Tranquilitiatis, Nectaris and Sinus Iridum.

What stood out visually in the binocs were the Jura Mountains on the northern shores of Sinus Iridum – they were on the terminator and the light was bright on its slopes to the mare floor. Couldn’t help but return again to view Iridum and the terminator. Showed both Linda and Mark at different times.

No breeze or clouds. An all-sky murkiness prevented great observing but didn't stop it.

Jupiter (in Ophiuchus)
Time: 9:47 PM ADT
Equipment: Binoculars, Telescope
Took out my binoculars then noticed the crescent Moon so also set up the telescope. Could see the 4 moons with both sets of equipment. Io on one side with Europa, Ganymede and Callisto on the other. They appeared to all be in a straight line except Ganymede that was just slightly above it. As noted in the sketch, I could see 3 stripes on the planet, with the southernmost one having 2 bumps on its northern edge.

   

Saturn (in Sagittarius)
Time: 9:50 PM ADT
Equipment: Visual, Binoculars, Telescope
Easily found Saturn near the Teapot handle, especially after finding Jupiter. Used binoculars to see all 4 moons - 2 on each side, forming what appeared to be a curve. I identified Rhea, Dione and Titan but wasn't sure if I saw a 4th moon or a star in that curve. In the telescope, the tilt of the planet and its rings were seen.

Stars - Alcor, Mizar A, Mizar B
Time: 10:21 PM ADT
Equipment: Telescope
S&T Chart Reference: 32, 43
Used my telescope in an attempt to find M101 (Pinwheel Galaxy) above Alcor and Alioth - but failed. However, I did see the split of Alcor from Mizar A and Mizar B.

   

M22 / NGC 6656
Time: 10:55 PM ADT
Equipment: Visual, Binoculars 
S&T Chart Reference: 67, 69
In identifying the location of Saturn, I realized we could actually see part of the Teapot in our backyard! The 4 stars of the handle plus Kaus Borealis and Kaus Australis were also identified. With binoculars, I located Kaus Borealis, found the "Y" shaped grouping of stars adjacent to it and then the faint fuzzy M22 was seen with averted vision.

Found - handwritten notes about this evening. I had noted the items observed during this evening in my 'draft' log book intending to write it up in the compiled log book - but failed to do so. There apparently was lots of light at the horizon and that it seemed murky.

All the items above were located and identified. The lower part of Scorpius' tail was in the area of the murky horizon.

It was noted that all 4 of the Galilean moons of Jupiter were visible in the binoculars. Jupiter was about 6.5º above Antares towards Sabik (in Ophiuchus). On the east side were Callisto and Europa. On the west side were Io and Ganymede. I noted that Io was relatively close to Jupiter compared to the other 3.

Saturn was located near the handle of the Teapot in Sagittarius. The rings were tilted (NW to SE). I made no note of any moons identified.

We were camping with the Chapmans again for our Annual Big Muise Island Star Party. New Moon. Breezy enough to keep the mosquitos away. Occasional clouds.

Delphinus
Time: 9:46 PM ADT
Equipment: Visual

Jerry, Dave and I could easily see all 5 stars of the constellation. Jerry then told us about how the 4 stars forming the 'head' of the dolphin was also an asterism - Job's coffin. It is referred to as a coffin because of its long, box-like shape. 

Job’s Coffin is formed by four relatively bright stars in Delphinus: Rotanev (β Delphini), Sualocin (α Delphini), γ Delphini ,and δ Delphini. The two unusual star names – Rotanev and Sualocin – come from the Latinized name of Italian astronomer Niccolò Cacciatore – Nicolaus Venator – written in reverse.

A fifth star, Aldufin (ε Delphini), forms the dolphin's tail.

Lore re Job's Coffin:
There are two myths associated with the constellation Delphinus:

1- The dolphin constellation represents Poseidon’s messenger. When the sea god courted the nymph Amphitrite, one of the Nereids, she resisted his advances and took refuge among her sisters. Poseidon sent messengers to find her and bring her to him, among them a dolphin. The dolphin found the nymph, soothed her and brought her back to the god. The two were later married. Poseidon decided to honour the dolphin and placed his image among the stars.

2- It was Apollo, the god of poetry and music, who placed the dolphin among the constellations for saving the life of Arion, a poet and musician born on the island of Lesbos, whose skill with the lyre made him famous in the 7th century BC. Arion was sailing back to Greece after a concert tour of southern Italy when the sailors who were also on the ship started plotting to take the money he had earned. Surrounded, Arion asked them to let him sing one last song. The sailors allowed this, and Arion’s music drew several dolphins to the ship. As he played, the dolphins swam alongside the ship and Arion decided to take a leap of faith and he jumped overboard. One of the dolphins saved him and carried him all the way back to Greece. In this version of the myth, Apollo placed the dolphin next to the constellation Lyra in the sky, and Lyra represents Arion’s lyre.

Jupiter (in Scorpius)
Time: 10:00 PM + 11:58 PM ADT
Equipment: Binoculars

Only 3 Moons were seen adjacent to Jupiter - Callisto, Io and Ganymede. Europa was being occulted by Jupiter.

M55
Time: 10:42 PM ADT
Equipment: Binoculars 
S&T Chart Reference: 67, 69

Looking at the S&T Pocket Star Atlas, I noticed M55 between the Teapot handle and the bottom of Capricornus.  I started with Ascella and worked my way towards ω Capricorni. I accidentally found it using averted vision - showed Dave where it was located on the star map and he found it as well. A very faint fuzzy.

In looking for info on this object, it was suggested to follow the arc of stars from τ Sagittari to ψ Sagittari to χ Sagittari to h2 (52 Sgr) and then go straight down to M55.

Sketch of where to find M55

Satellite (ISS)
Time: 10:50 PM ADT
Equipment: Visual, Binoculars 

It appeared near Arcturus then disappeared just past Altair. Very bright and very fast! And very large compared to other satellites.

Satellite
Time: 10:55 PM ADT
Equipment: Visual, Binoculars 

First noticed while on its path between the Keystone of Hercules and Corona Borealis. It Passed through Ophiuchus then disappeared between Antares and Dschubba.

Meteor
Time: 11:02 PM ADT
Equipment: Visual

Bright flash to the right of Serpens Caput, less than one second duration.

Satellite
Time: ~ 11:20 PM ADT
Equipment: Visual

   

Noticed it coming across the top of Ophiuchus and travelling across a corner of the Keystone of Hercule. It disappeared just past the Keystone.

M70
Time: 11:35 PM ADT
Equipment: Visual, binoculars 
S&T Chart Reference: 67, 69

Used my binoculars to attempt to find M70 approximately midway between Ascella and Tau Borealis in the Teapot. I could find M69 and M54 but M70 alluded me once more. Use a telescope next time!

   

M4 + Scorpius
Time: not recorded
Equipment: Visual, binoculars 
S&T Chart Reference: 56, 58

Scorpius was identified visually in the S-SE with Antares clearly visible naked eye and with binoculars. Could see as far down the tail/stinger as ε Scorpii before the remaining stars of the constellation disappeared in the murkiness. Was able to locate M4 adjacent to Antares.

M13 
Time: not recorded
Equipment: Visual, binoculars 
S&T Chart Reference: 52

As was the case last evening, the Keystone of Hercules was near the zenith and all 4 stars easily identified.

M13 was easily found visually and with binoculars between η Herculis and ζ Herculis.

 

M69 (Globular cluster)
Time: 12:25 AM ADT
Equipment: Binoculars 
S&T Chart Reference: 67, 69

There was a curved formation of 3 stars from Kaus Australis towards the inside of the Teapot. Just above this curve was M69. 

I hadn't been able to find M69 for a couple of years, despite good seeing and visibility. Perhaps my cataract surgery made a difference(?).

Sketch of where to find M69

Note: The 3 stars starting at Kaus Borealis are HR 6893, HD 169706 and HR 6936.

M54 / NGC 6715 / Summer Rose Star
Time: 12:25 AM ADT
Equipment: Binoculars 
S&T Chart Reference: 67, 69

I had been unable to find this object for a couple of years.

Focused my binoculars with Ascella at 9 o'clock in my FOV. Found M54 with averted vision! Finally.... success! It was very faint but it was found. I returned to this location later in the observing session to confirm I could find it again.

We were camping with the Chapmans again for our Annual Big Muise Island Star Party.  Around 10:35 PM, lightning periodically lit the sky; Jerry determined the storm was centred over St. Stephen, NB. A little breezy but it did keep the mosquitoes away. The New Moon was expected at 12:12 AM ADT.

Varying degrees of transparency and seeing as the night progressed. Clouds occasionally covered the Teapot that affected the visibility of the stars and globular clusters in the area.

Lyra
Time: 9:35 PM ADT
Equipment: Binoculars
S&T Chart Reference: 63

Vega appeared overhead around 9:35 PM. Could easily see the locations of β, ζ, and ε Lyrae. Did not pay particular attention to δ and γ Lyrae.

With binoculars, I could see the double stars of ε and ζ. Not sure if I saw β1 and β2, or if it was Sheliak (β1 & β2 as one star) and ν (ν1 & ν2 as one star).

   

Delphinus
Time: 9:46 PM ADT
Equipment: Visual

At this time, sections of the sky were clear but very murky near the horizon. Used naked eye to find and identify all 5 stars item constellation. 

Scorpius
Time: not recorded
Equipment: Visual, Binoculars

Scorpius was identified visually in the S-SE although its tail wasn't visible due to the murkiness at the horizon. The red Antares was clearly visible naked eye and with binoculars. Dave pointed out the 2 stars adjacent to Antares (σ Scorpii and τ Scorpii) both had the same name - Al Nayat. Could see as far down the tail/stinger as ε Scorpii before the remaining stars of the constellation disappeared in the murkiness.

   

Jupiter (in Scorpius)
Time: 9:54 PM ADT
Equipment: Binoculars, Telescope

Observation 1 with Binoculars:
Two Moons were on each side of the planet but not in a straight line; Ganymede was slightly above the line formed by the other 3. Ganymede and Callisto were close to Jupiter so required a longer look-see to distinguish them from each other and from the planet.

Observation 2 with Telescope:
I could see 3 bands on Jupiter but could not see the Great Red Spot (GRS). 

   

M4 / NGC 6121
Time: 9:54 PM ADT
Equipment: Visual, Binoculars
S&T Chart Reference: 56, 58

Using the binoculars, I could find the small fuzzy M4 at 4 o'clock to Antares.

M6 / Butterfly Cluster
Time: 10:10 PM ADT
Equipment: Binoculars
S&T Chart Reference: 69, 67

I used Kaus Borealis in the Teapot to find M6 approximately 1.5 FOV away. The grey fuzzy was visible but not as clearly defined as in the past due to the haziness in that part of the sky.

Keystone Hercules + M13 / Hercules Globular Cluster
Time: 10:09 PM ADT
Equipment: Visual, Binoculars

I found the Keystone of Hercules almost at the zenith and located all 4 of its stars. Using binoculars, I was able to find the small grey fuzzy between η Herculis and ζ Herculis without any difficulty.

M7 / Ptolemy's Cluster / NGC 6475
Time: 10:10 PM ADT
Equipment: Visual, Binoculars
S&T Chart Reference: 67, 69

In clearer skies, the cluster would have shone almost as brightly as the Pleaides. It was easily located naked eye as a dullish object. I followed the line from Ascella to Kaus Australis in the Teapot and went out 1.5 FOV. The murkiness creating poor seeing and transparency in this part of the sky was quite evident. 

M8 / Lagoon Nebula
M20 / Trifid Nebula
M21
Time: 10:25 - 10:40 PM ADT
Equipment: Binoculars
S&T Chart Reference: 67, 69

Made a line from Kaus Australis through the mid-point of the line at the top of the spout, then travelled an equal distance to M8. Could easily see the bright open cluster of M8; could also see M20 in the same FOV. M21 is very close to M20 and therefore easily found within the same FOV.

Saturn (in Sagittarius)
Time: 10:12 PM ADT
Equipment: Visual, Binoculars, Telescope

Observation 1 - Visual:
Could easily see Saturn near the Teapot's handle. Much brighter than other stars around it. 

Observation 2 - Binoculars:
With binoculars, I could identify the tilt of the rings but could not see the separation between the rings and the planet.

Observation 2 - Telescope:
With Dave's telescope, I could see the separation of the rings from the planet. A small portion of the planet could be seen beneath the rings. Three darkish bands could be seen on Saturn.

   

M11
Time: 10:38 PM ADT
Equipment: Binoculars
S&T Chart Reference: 67

Discovered that M11 is located in the Scutum Star Cloud below a dark nebula Bernard 111. 

I easily found a 'square' portion of the Cloud with 2 bright objects in its upper border. With binoculars, I found M11 as the left bright object and guessed (with star charts help) that the right bright object was β Scutum. 

I still consider M11 as the "golf ball" next to an asterism shaped like a golf club.

Note:
The stars comprising the golf club head are HR 7803, R Sct, HD 174005 and HD 173744. The club handle stars from the head downwards are HD 173278, HR 7034, HR 7024 and HR 7007.

Next time I will have to see if it can be found using the south end of Aquila.

 

M22
Time: 10:45 PM ADT
Equipment: Binoculars
S&T Chart Reference: 67, 69

Again, I used Kaus Borealis to locate M22 within the same FOV. It appeared as a small grey fuzzy with no particular details in binoculars.

IWLOP #058 - Cuvier

IWLOP #058 - Cuvier

Crater with a smooth floor. Cuvier is located almost due south of the prominent crater Maurolycus (Rukl 66) in a heavily cratered area of the Moon that is an interesting challenge to navigate.

Location: 50.3 S 9.9 E    Origin: Impact     Size: 75 km     Rukl: 74     Type: Simple Crater (CS)

Objects: Cuvier + Q, F, A, E, B, L, H; Baco, Ascelpi, Tannerus, Mutus, Manzinus, Jacobi, Kinau

No clouds or wind. Relatively warm night.

R1: Located Cuvier SE of Heraclitus. Slight oval shape with crater impact on NE rim. Five craters curved to the SE - Q, E, A, E, B). Also found L & H on NE rim.

C1: Found all 3 craters (Baco, Asclepi and Tannerus) to the east and SE.

Baco: worn down rims, oval shaped, smooth floor. Several craters near its rim.

Asclepi: SE of Baco. Crater floor appeared smooth.Easily identified sub-craters B, D, G, H along with A and E. Looked like a squished diamond shape.

Tannerus: Sub-craters formed a right angle with Tannerus at the corner.

     

C2: Further SE, I found Mutus and Manzinus and to the south Jacobi and Kinau. I knew Kinau formed a triangle with Mutus-Manzinus and it wasn't easily found. The Moon was favourably librated so could identify others even further south.

Mutus: Craters A, B and V found on smooth floor. Steep eastern rim versus the ridged west rim. Crater A adjacent to the rim. Crater B just off-centre to the west and completely on the crater floor. Crater V was in the east and was the largest of the three.

   

Manzinus: Craters D, E and G on SW sloped rim, plus C and N.

Jacobi: Impact crater O on northeast rim and J on southwest rim, plus N, K, W on the crater floor.

NOTE: Search, Rosenberger, Vlacq, Biela and Hagecius formed a grouping NE of Mutus.

Maurolycus and Barocius both had terraced walls. Especially visible were the SE sides that seemed steeper than the other sides. Maurolycus had a central peak plus at least 4 very small craters within. There is a flat area in the SW that may be the remnant of a crater it impacted (???). Barocius looked like a rabbit’s face. Almond-shaped face with 2 ears – craters B & C. The floor didn’t appear smooth. The northern rim of C seemed very shallow. The rim of B seems very shallow as if it is disappearing after its impact.

No wind. No clouds. Jerry set up the 10” Meade SCT while I attempted to identify items on my observe list – potentially 13 items, depending on where light & terminator were located. Because the SW limb was librated, I was able to find Bailly.

C1: Because it was on the terminator, Bailly appeared very elongated. One of its walls was on the terminator but features within its crater walls were quite easily seen.
C2: At least 7 craters on the floor or on its walls. It was difficult to determine if the walls were ridged or whether the floor looked rough near the walls.

Temperature: -2º C
SQM: 17.81

No wind or clouds. Jerry set up the telescope for me then I began looking for things on my observe list - 13 items, depending on where light and the terminator were located. I found Grimaldi (on the list) and then had 3 surprises due to the SW limb being librated - Bailly, Cassatas and Klaproth.

Bailly
One of Bailly's walls was on the terminator but features of its crater walls and rough floor were quite evident. Refer to IWLOP #L8 (Libration Object) - Bailly for details of the observation.

Cassatas and Klaproth
Smooth floors, small in size and the overlay of one crater over the other reminded me of Sirsalis/Sirsalis A. Refer to IWLOP #107 - Klaproth & Casssatus for details of the observation.

Grimaldi
This was the first time viewing this crater. Grimaldi's west wall was on the terminator. The almost lace-like Damoiseau was to the east with Sirsalis and Sirsalis A to the S-SE. Appeared to be doors on the very dark floor. Refer to IWLOP #134 - Grimaldi for details.

IWLOP #083 - Rupes Recta

IWLOP #083 - Rupes Recta

The famous "Straight Wall" is one of the most interesting features on the Moon.

Location: 22.0 S 7.0 W    Origin: Tectonic     Length: 110 km     Rukl: 54     Type: Scarp

Objects: Rupes Recta, Birt, Promontorium Taenarium, Birt A, Rima Birt
Others Identified: Nicollet, Thebit, Thebit A

Observation 1:
Location: Home

Date: 2019-04-14
Time: 8:01 PM ADT
Equipment: 6" Skywatcher Dobsonian
Eyepiece: 10mm

Magnification: x120
Seeing: Good (3) - Very Good (4)
Transparency: Good (3) - Very Good (4)
Temperature: 10° C

Variable high clouds.

R1: The Straight wall was barely visible. 
R2: The crater Birt in Mare Nubium to the west was easily identified.
R3: Promontorium Taenarium was very large - 1/4 as long and almost as long (east to west) as the Wall. The curve of the peaks made it look like a wall of a much larger crater (now gone).
   

Observation 2:
Location: Home

Date: 2020-08-28
Time: 9:50 PM ADT
Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm with 82° FOV

Magnification: x530
Seeing: not recorded
Transparency: not recorded
SQM: 18.6 - 18.7 
Temperature: 14° C - 12° C

C1: Birt and Birt A were easily identified adjacent to the Wall. The shadow extended just west of Birt almost perfectly parallel to the Wall. Because this part was near the terminator, I could see the worn down crater wall (refer to note). Rimae Birt ran parallel to the Wall, running north of Birt; it was about half the length of the Wall.

NOTE: (July 4/21) It always strikes me that there had been a large crater in this section of Mare Nubium because of the hint of a circular wall in the Mare floor.

 

Observation #3:
(Photo & Notes from Lunar Session - June 14, 2024)

Location: Home
Date: 2024-06-14
Time: 9:00 PM - 10:15 PM
Equipment: 10" Meade SCT
Eyepiece: Tele Vue Nagler 9mm Japan eyepiece

Magnification: x278
Temperature: 20° C
Seeing: Fair (4)
Transparency: Good (3)

This is not the best photo possible. It was taken using my iPhone mounted on the eyepiece with a NexYZ while doing a general 'look' at the Moon.

The straight line defining the lit area from a dark area of Mare Nubium is Rupes Recta aka the Straight Wall! It's the absolute best example of a lunar fault. Rupes Recta casts a wide shadow that gives it the appearance of a steep cliff. The fault has a length of 110 km, a typical width of 2–3 km, and a height of 240–300 m. Thus although it appears to be a vertical cliff in the lunar surface, in actuality the grade of the slope is relatively shallow.

Thebit (circular crater on left with most of its floor in darknesss, Thebit A, the small Thebit L beside A, Thebit J nested beside Thebit, and Rupes Recta! Thebit A appears to have impacted both Thebit and Thebit L. The crater Birt is the illuminated crater in the shadows. Promontorium Taenarium was very large and well illuminated at the south end of the Wall; an intermittent ridge line ran from Thebit J to the south end of Rupes Recta, creating what looked like a break in the Wall just before the Promontorium.

Lunar Session - April 11/12, 2019

This session was devoted to lunar observing. Most of it was directed at finding objects in the Isabel Williamson Lunar Observing Program (IWLOP).

Lunar Phase: Waxing Gibbous (90.6%)
Q-Day: 4

Moonset: 6:10 AM        Moonrise: 8:52 PM     
Sunset: 12:15 AM          Sunrise: 8:02 PM

Location: Home
Date: 2019-04-11/12
Time: 10:00 PM - 12:45 AM
Equipment: 10" Meade SCT, 10 mm eyepiece
Magnification: x250

Transparency: Very Good (4)
Seeing: Excellent (5)

No wind, no clouds. The Moon was in the middle of the Winter Circle.

There were numerous IWLOP targets found that despite the beautiful temperatures I made rough sketches of the objects at the eyepiece, wrote notes regarding the required (or challenged) IWLOP observations, did rough sketches then completed the details later. I also noted some craters not required to view along with the targets. I tried using a x2 Barlow with some success but the x3 Barlow was too fuzzy/grainy.

Time: 10:10 PM ADT
The first target was IWLOP #52 - Montes Haemus and the Mare Serenitatis Lacus Group. The Lacus Group in particular was very interesting give the number in 

Time 10:29 PM ADT
The second targets were Aristoteles, Eudoxus, Rima Ariadaeus, and IWLOP #48 - Aristoteles & Eudoxus
. It was very interesting to compare these two craters for size, depth and features. 

Time 10:38 PM ADT
Temperature: 9º C
SQM: 19.25
Completed IWLOP #41 - Mare Serenitatis
. The numerous dorsa on the mare floor were intriguing and at times a challenge to find. 

Time 11:21 PM ADT
Equipment: 10" Meade SCT, 10 mm eyepiece + x2 Barlow
Magnification: x1060
Completed IWLOP #33 - Posidonius. The crater floor with its roughness and numerous rime made this an interesting find.

Time 11:30 PM ADT
Completed IWLOP #53 - Rima Ariadaeus. The fact that it cut across mountains, ghost craters and through ridges with craters was intriguing. I wondered what had created such a long rift across the Moon's surface (but didn't investigate any further.

Time 11:45 PM ADT
Completed IWLOP #56 - Dorsa von Cotta & Dorsum Buckland. In searching this area of Mare Serenitatis, I found not find the feature named Rimae Sulpicius Gallus. However, if I ever own a dog again, I'd love to name it "Sulpicius" - 'Sully' for short.

Time 11:52 PM ADT
Temperature: -1º C
SQM: 19.32
Completed IWLOP #65 - Hipparchus. The ghost craters on its floor and its somewhat square shape were interesting.

IWLOP #033 – Posidonius

IWLOP #033 – Posidonius

Flooded crater from the Upper Imbrian Era. The interior ring is higher than the lunar mean surface in the eastern portion. It has very irregular terrain. There are 5 separate rimae within Posidonius; these possibly happen when a large impact occurs on the edge of an already fractured basin.

Location: 31.8 N 29.9 E   Origin: Impact    Size: 95 km    Rukl: 14     Type: Complex Crater (CC)

Objects: Posidonius, Posidonius A, Chacornac, Chacornac A
Others Identified: Daniell, Luther, Le Monnier, Posidonius craters B, D, J, M, O, P

Location: Home
Date: 2019-04-11
Time: 11:21 PM ADT
Equipment: 10" Meade SCT
Eyepiece: 10mm + x2 Barlow

Magnification: x1060

Transparency: Excellent (5)   

R1:  Posidonius had one large hill on its floor along with what appeared to be ridges or smaller hills. Round and deep Posidonius A was just west of centre.
R2: Chacronac appeared shallow compared to Posidonius. Its NW crater wall appears non-existent except for Posidonius' crater ridge.

C1: I found two of the rimae within Posidonius, one running NW to SW and one running NE to SW.
C2: Chacornac A is almost centred in the crater. Very small and shallow. Had to stare for a period of time before it appeared.

Eyepiece: 10mm

Magnification: x250
Seeing: Very Good (4)
Transparency: Excellent (5)   

R1:  Dorsa Smirnov and Dorsa Lister form a partial semi-circle that extended to Bessel and to its north. The structure formed by Dorsa Lister almost looks like a 'ghost crater'.
R2: The area surrounding the Dorsa Aldrovandi from Mons Argaeus to Posidonius and the crater Le Monnier is darker than that of the adjacent mare floor. Its also dark south of Dorsa Lister.

C1: The crater Very appears as a bright spot in the north end of Dorsa Smirnov. Very appears to be on the wall of a 'ghost' crater to its north and is also a darkened area.
C2: Dorsa Nicol heads northward and is perpendicular to the dark area of Rimae Plinius, terminating at Dorsa Lister. Dorsa Azara has a curve NW to SE and extends past Sarabhai.

IWLOP #048 - Aristoteles & Eudoxus

IWLOP #048 - Aristoteles & Eudoxus

Spectacular pair of craters located at the edge of Mare Frigoris, the "Sea of Cold." These two prominent craters can be easily identified using binoculars.

Location: 50.2 N 17.4 E    Origin: Impact     Size: 87 km (Aristoteles), 70 km (Eudoxus)     Rukl: 5, 13     Type: Complex Crater (CC)

Objects: Aristoteles, Eudoxus, Mare Frigoris, Egede, Galle, Sheepshanks, Sheepshanks C, C. Mayer, Arnold
Others Identified: Democritus, Kane

Location: Home
Date: 2019-04-11
Time: 10:24 PM ADT

Equipment: 10" Meade SCT
Eyepiece: 10mm

Magnification: x250
Seeing: Very Good (4)
Transparency: Excellent (5)  

R1: East wall of Aristoteles was especially terraced. Could see a circular pattern near the shadows on the west wall.
R2: Eudoxus is a deep crater with steeply terraced walls and a central peak. 
R3: Aristoteles crater walls are not as tall as those of Eudoxus and its floor was smooth. Eudoxus had steeper walls and showed rises in the floor and small craters; its ejecta field is also smaller. In comparison, Tycho is higher-sided and has a much larger ejecta field and rays.
R4: Egede looked diamond-shaped and well flooded. Mitchell was quite shallow and its west wall impacted by Aristoteles. Galle was north of Aristoteles in Mare Frigoris and appeared quite shallow.

C1: The 2 peaks in Aristoteles were observed; the multiple central uplifts in the floor of Eudoxus were noticed.
C2: The 4 secondary craters were located. Sheepshanks and the much smaller Sheepshanks C were north across Mare Frigoris from Aristoteles. Mayer was just north of Sheepshanks. I looked west from Mayer to Kane and then NW from there to observe Arnold, a shallow elongated crater with an irregular north wall.

Spent most of this evening observing objects in the RASC IWLOP. Some of the objects were also included in the RASC ETM(T) observing program as well.

Sketch from IWLOP #053: Rima Ariadaeus

Julius Caesar was viewed with the 10” Meade SCT at x250 magnification at 10:40 PM. Could see the E-SE wall was eroded or non-existent. It looked like the floor was filled/flat but wasn’t sure. Will require another look.

Hipparchus was viewed at 11:52 PM.

It had smooth floors except for the two ghost craters and craters X and N, the latter being slightly off-centre. It also looked like there was an opening in the NW towards Sinus Medii.

The crater Horrocks was inside the crater in the N-NE and had a dark floor in shadow; Halley looked to have impacted/affected the SE rim.

No wind, high cloud slowly moving over the Moon. On our return from a family BBQ and bonfire in Middle Sackville, we noticed the clear sky and Moon to the W/SW, still high enough to observe. Set up the telescope in the backyard.

After locating Langrenus and Vendelinus (x120 mag), I used my “new to me” x3 Barlow, then my x2 Barlow.

The visible SE limb was awash with illumination so couldn’t see/identify any craters.

Closer to the terminator was easier but seeing/transparency reduced the ability to observe features of craters beyond shadows. Disappointment!

There was Earthshine this evening naked eye.

Clouds rolled in so packed up.

Jerry and I were invited to the Hamilton home for an overnight observing session. Given their clear skies and incredible horizon, we accepted their invitation. 

Zodiacal Light
We watched the Sun set and saw the Zodiacal Light (ZL) rise on the western horizon. Beautiful! In the Atacama, Mars was centred in the base of the ZL but in Litchfield it was east of the ZL.

Mars
Time: 7:15 PM - 1:00 AM ADT
Equipment: Visual + Binoculars 
Mars was first sighted SW of Aldebaran and south of the Pleiades. Although the relative placements of the stars and planet remained consistent, it was amazing to see how far the planet had 'travelled' during this session - approximately 30º - 40º to the NW horizon. WOW.

Satellite (ISS)
Time: ~ 9:08 PM ADT
Equipment: Visual + Binoculars 
Noticed the ISS travelling towards us. The path was from above Aldabaran, above the Pleiades, over Cassiopeia, and then disappeared to the left and below the handle of the Big Dipper. Very bright throughout its entire path. Could see a sort of diamond shape through the binoculars, but could not clearly see the 'wings'.

M42 / Orion Nebula / NGC 1976
Time: 9:40 PM ADT
S&T Chart Reference: 16
Equipment: Visual, Binoculars 
Orion was very clear above the treeline in the sky opposite from Melody's observatory. Used my binoculars to very easily see this object.

M44 / Beehive Cluster / Praesepe
Time: not recorded
S&T Chart Reference: 23, 25
Equipment: Visual, Binoculars 
Located the star Ascellus Australis in Cancer to find M44 adjacent. I could actually see this open cluster visually. Also viewed it with binoculars

M67
Time: not recorded
S&T Chart Reference: 23, 25
Equipment: Visual, Binoculars 
Located the star Acubens in Cancer to find the grey fuzzy M67 nearby. RASC Halifax Centre had thrown out the challenge to members to look for M67. Dr. Roy Bishop had provided a chart for us to determine their magnitude limits. All 4 of us attempted to use the chart but could not see the variation in the stars to the degree depicted in the chart.

Orion's stars
Time: 12:00 AM AST
S&T Chart reference: 14
Equipment: Visual + Binoculars 
I noticed a very bright object above Orion that formed a triangle with Betelgeuse and Bellatrix, something that was never obvious from our home. Turned out to be Meissa, φ1 Orionis, φ2 Orionis and HR1883. The cluster of stars was the most brilliant I had ever seen them.

   
M35 / NGC 2168
Time: 1:12 AM ADT
S&T Chart Reference: 23, 25
Equipment: Visual, Binoculars 
Sitting in their living room, I noticed an arch of stars above Orion. Turned out it was the 'feet' of the twins in Gemini. Knowing that, I used my binoculars to easily find the fuzzy M35.
 
Canis Major
Time: not recorded
S&T Chart Reference: 27
Equipment: Visual

All the stars were very clear and for the first time I actually saw a "dog" formation, complete with tail.
   

Eridanus
Time: not recorded
S&T Chart Reference: 6. 16, 17
Equipment: Visual 
Melody pointed out this constellation that began at Orion's Rigel. We were able to identify a little less than half of the stars in this large constellation.

In the Atacama, we had seen the end star Achernar, but only a portion of the "river" could be seen here.

   

Gemini
Time: not recorded
S&T Chart Reference:
23, 25
Equipment: Visual 
Sitting in the warmth of their living room, I noticed an arch of stars above Orion. I soon realized it was the "feet" of Gemini. Looking further up were the stars Castor and Pollux, their bodies, arms, and legs - all clearly seen and identifiable.

Lepus
Time: not recorded
S&T Chart Reference: 16
Equipment: Visual  
All the stars of this constellation were clearly visible below Orion. Ne need for binoculars!

Melotte 111
Time: not recorded
S&T Chart Reference: 45
Equipment: Visual + Binoculars
Jerry noticed this first and then I used our binoculars to view it. It was amazingly bright visually and certainly very bright in binoculars. Melody used her telescope to find it and I had a brief viewing of it through it.

IWLOP #095 - Copernicus

IWLOP #095 - Copernicus

A prominent crater that is the prototype of the Copernican geological period. Copernicus features spectacular central peaks and is surrounded by both a prominent ejecta blanket and numerous secondary craters. The impact that formed Copernicus occurred about one billion years ago. It is easily visible in binoculars, particularly when near the terminator, and is by far the most prominent feature in the otherwise mostly flat Mare Insularum.

Location: 9.7 N 20.0 W    Origin: Impact     Size: 93 km.     Rukl: 31     Type: Complex Crater (CC)

Objects: Copernicus, Kepler, Tycho
Others Identified: Fauth, Guy-Lussac

Observation 1:
Location: Home
Date: 2019-03-20
Time: 9:16 PM ADT
Equipment: 10” Meade SCT
Eyepiece: 10mm
Magnification: x250
Seeing: Very Good (4)
Transparency: Very Good (4)

R2: The Copernican rays extend half way into Mare Imbrium, eastward into Mare Vaporum via Sinus Aestuum, NW through Montes Carpatus to Aristarchus. They overlap Kepler in the west.

C1: Did not complete this challenge in either observing session 1 or 2.
C2: 
Copernicus has a large number of shorter, overlapping rays, leaving the impression of a squashed tarantula. Whereas Copernicus' rays extend over the NW quadrant of the Moon, Tycho's rays extend over most of this side of the Moon, from the SW limb, NW to Mare Cognitum, Down to Mare Australe, NE into Mare Serenitatis, E to Mare Nectaris and Asperitatis. In essence, Tycho's rays cover a little over half the surface we see.

IWLOP #118 – Schiller & the Schiller-Zucchius Basin

A crater that is very elongated, perhaps as a result of a very low-angle impact or the merging of two crater structures. The Schiller-Zucchius Basin is the remains of a very large, ancient impact.

Origin: Impact   Diameter: 179 x 71 km   Rukl: 71    Type: CC & Basin

Objects: Bayer, Phocylides, Rost, Schiller, Schiller-Zucchius Basin, Weigel, Zucchius

IWLOP #086 - Tycho

One of the youngest craters on the Moon, Tycho is inconspicuous during most of the lunar day, but comes into its own at the Full Moon where its rays can be traced over much of the lunar surface. The Tycho impact may have occurred as recently as 100 million years ago!

Location: 43.3 S 11.2 W    Origin: Impact     Size: 85 km     Rukl: 64     Type: Complex Crater (CC)

Objects: Tycho, Street, Pictet, Surveyor 7 landing, Sassiredes

R1:  Tycho had a very prominent central peak, steep walls and darker ejecta in the north and northwest. Street and Pictet are two craters that form part of what I term the "flower petals" surrounding Tycho.

C1: Surveyor 7 landed a short distance north of Tycho's rim. Not exactly a smooth-looking surface in large quantities for the lander's landing. Sasserides, Saussure and Orontius were identified. There were numerous small unnamed craters as well.

Note: Under certain light, Tycho looks like a flower centre with several small flower petal encircling it. Loe this crater's show of ejecta on the full Moon!

IWLOP #096 - Mare Imbrium / Eratosthenes / Copernicus System

This area of the Moon illustrates the overall pages of the major systems. You can trace out the relative ages of each by noting which crater is overlain on the other. 

Origin: Impact and Volcanic      Size: Various      Rukl: 19-22, 9-12, 31      Type: Various

Objects: Mare Imbrium, Archimedes, Eratosthenes

NOTE:  Archimedes appears shallower than Eratosthenes (based on shadows in their craters). Eratosthenes had taller/longer shadows on its floor and towards the terminator.

IWLOP: Note these features My Observation
Mare Imbrium lavas fill crater Archimedes; they are post-impact, but pre-Imbrium. R1:  The opening in the NE Archimedes wall allowed for the lava to fill the crater.
The crater Eratosthenes is post-Mare Imbrium but pre-Copernican. R2: In this session, a  large shadow covered most of Copernicus' floor.
The crater Copernicus is the most recent major impact in this area and overlies older structures. R3: Copernicus and Montes Carpatus were located.
The ejecta blanket surrounding Mare Imbrium is the oldest part of this system and dates back to the Imbrium impact itself. It is especially noticeable in some areas, e.g., in the area of the crater Julius Caesar (Rukl 34). R4: Mountainous area on shores of Mare Imbrium evidence of ejecta.

IWLOP #106 - Sinus Iridum

IWLOP #106 - Sinus Iridum

Massive, spectacular, flooded crater on the edge of Mare Imbrium. It combines the high mountains of Montes Jura with a missing southeastern rim & two prominent “capes.” Sinus Iridum covers more than 10 degrees of the lunar surface and may require various terminator angles for optimum views of all the features listed.

Location: 45.0 N 25-37 W    Origin: Impact and Volcanic     Size: 260 km   Rukl: 9, 10     Type: Simple Crater (CS)

R1: Montes Jura is a half circle structure on the north shore of Sinus Iridum, light in colour compared to the Mare floor. The crater Bianchini impacted the crest  of its northern wall.
R2:  Both Promontoria LaPlace and Heraclides appear steep sided and rugged, projecting into Mare Imbrium at both the eastern and western tips of Montes Jura respectively. 
R3: Helicon and le Verrier craters are aligned and point to Promontorium Heraclides. The crater C. Herschel is to the SW of this promontorium. 

C1: Sharp and Mairan appear as deep oval craters versus the irregular shape of Maupertius. The latter may be misshapen perhaps because of many previous impacts filling it in (?).
C2: The Luna 17 landing site is south of Sharp and SW of the Promontorium Heraclides on the seemingly flat Mare Imbrium.

Saw the Moon during my walk from 2:30 PM – 4:30 PM so decided it would be a good evening for observation. I was also interested in completing one or two items in the IWLOP.

I included my rough sketch of “Huggins, Nasireddin & Miller” in my ETM logbook; a detailed sketch is in IWLOP #72.

Also observed Saussure, Proctor, Orontius, and Walther but didn’t draw them in detail.

I then looked at the area around Mare Vaporum.

Craters: Archimedes, Aristillus, Autolychus, Eratosthenes

Craters not in ETM List: Bancroft, Huggins, Huggins A, Miller, Miller H & C, Nasireddin, Orontius, Proctor (didn’t sketch but did locate), Saussure, Wallace, Walther

Maria: Imbrium, Palus Putredinis (P), Vaporum

Rimae: Rima Bradley (RB)

IWLOP #070 - Montes Apenninus & Apennine Bench

IWLOP #070 - Montes Apenninus & Apennine Bench

Spectacular mountain range with heights to 5,000 metres; best seen at first and last quarter. 

Location: 20.0 N -  10.0 W - 6.0 E    Origin: Impact and Tectonic      Length: 600 km (Monte Apenninus)     Rukl: 22, 21     Type: Mount

Objects: Montes Apenninus, Apennine Bench, Mare Imbrium, Montes Carpatus, Montes Alpes, Mons Hadley, Mons Hadley Delta, Mons Bradley, Mons Huygens, Mons Ampère, Mons Wolf, Apollo 15 landing site
Others Identified: Bela, Conon, Vallis Alpes


Location: Home
Date: 2019-03-14
Time: 7:15 PM ADT
Equipment: 6" Dobsonian
Eyepiece: Super 25mm wide angle long eye relief + x2 Barlow

Magnification: x96
Seeing: Good (3)
Transparency: Good (3)

This observation was two days after First Quarter.

R1: Located the full range of the Montes Apenninus that forms the southern Imbrium basin.
R2: 
I followed the Montes Apenninus northward to locate Montes Caucasus and Montes Alpes with the Vallis Alpes. I went westward to locate Montes Carpatus.

C1: I located and sketched the northern portion of the mountain range that contained Mons Hadley, Mons Hadley Delta, and Mons Bradley. However, Mons Huygens, Mons Ampère, and Mons Wolf were also located and identified in the southern range.
C2:  Identified the Apennine Bench.
C3: Rima Hadley was near the Apollo 15 landing site. It formed a curve into Palus Putredinus; only its peaks were visible.

NOTES: (from a web search re definition of "Apennine Bench"):
"The term Apennine Bench Formation (ABF) was originally used to denote the diamond-shaped zone of relatively smooth, flat light-gray material that has high albedo (reflectance) situated roughly midway between Montes Apenninus and Archimedes and is somewhat larger than Archimedes in size. It has a unique "KREEP" chemical signature. The acronym ‘KREEP’ is used to identify higher abundances of potassium (K), rare earth elements (REE), and phosphorus (P). By relative dating, we can tell that the ABF formed after the Imbrium basin impact event (around 3.85 billion years ago)and before Mare Imbrium – the massive lava deposit that erupted within the basin, filling it to about half its original depth. This stratigraphy (time order) tells us that the ABF could be an example of pre-mare volcanism, whose magma came from a different source than the later basaltic eruptions that cover about 30% of the nearside. Since its formation, the ABF has been modified by many impact craters."

General Session - November 13, 2018

Star Cluster: Hyades (in Taurus)
Could not Find: M47 / NGC 2422

Location: Home
Date: 2018-11-13
Time: 12:45 AM - 1:15 AM  AST
Equipment: Binoculars, 10x42 IS
Transparency: Poor (1)
Seeing: Poor (1)
Temperature: -1º C
SQM: 19.25

Seeing and visibility were very poor with high cloud/haze obliterating many stars. The Moonset was around 10:15 PM the previous evening so was not a factor.

Hyades / Melotte 25 / Caldwell 42 / Collinder 50
Time:
S&T Chart Reference: 15

A very hazy sky. Only the brightest stars were seen naked eye, and with binoculars I could barely make out the Hyades star field.

I found Aldebaran using Orion's Belt stars as the pointer. With the binoculars, I easily found σ1 and σ2 plus θ1 and θ2. I sketched the star field as seen in my binoculars. The shaded area signifies the open cluster Hyades. θ1 was at 1 o'clock to θ2 at this hour of the morning. I noted the magnitudes of the identified stars once back in the house, especially since many of them were variables or variable doubles.

   
Sketch of where M47 should be found
 

M47 / NGC 2422
Time: 12
S&T Chart Reference: 27

In between the observation of Taurus θ1 and θ2, I attempted to look for M47. According to SkySafariPro, it should have formed a triangle with Procyon and Sirius. However, the haze meant M47 was nowhere to be found nor were any stars in the constellation Puppis. I will have to wait for better seeing and transparency - and use a telescope! My 6" Dob or 10" Meade SCT should do the trick.

Lunar Session - September 17, 2018

This session was devoted to lunar observing. IWLOP objects were completed and Mars and Saturn were observed.

Lunar Phase: Waxing Gibbous (59.6%)
Q-Day: -1

Moonrise: 3:17 PM
Sunrise: 7:02 AM          Sunset: 7:28 PM

Location: Home
Date: 2018-09-17
Time: 7:30 PM - 10:45 PM ADT
Equipment: 10" Meade SCT, 10 mm eyepiece (+ x2 Barlow)
Magnification: x250

Transparency: Good (3)
Seeing: Fair (2)
Temperature: 24º C
SQM: 17.58 - 19.11

My main objective was to check off more items from the RASC Explore the Moon (Telescope). In doing so, it meant I cold also observe several IWLOP objects: 

  • IWLOP #068: Montes Alpes & Vallis Alpes
  • ILWOP #069: Aristillus & Autolycus
  • IWLOP #071: Walther (Walter before 1979)
  • IWLOP #073: Regiomontanus & Purbach
  • IWLOP #074: Arzachel, and
  • IWLOP #075: Ptolemaeus & Purbach. 

I also took some time to locate two planets:

Saturn
Time: 8:05 PM ADT
Equipment: Telescope

Viewed Saturn west of the Moon in the southern sky. Able to see the planet and one of its moons (Titan). The rings were clearly visible as well.

 

Saturn with Titan

 

Mars
Time: 10:20 PM ADT
Equipment: Visual + Telescope 10 mm eyepiece + x2 Barlow
Magnification: x500

Visually, Mars twinkled slightly. Using the telescope with the x2 Barlow with seeing that was not the greatest meant I had a blurred view of the planet. However, I catch sight of the northern polar cap occasionally.

IWLOP #068 - Montes Alpes & Vallis Alpes

IWLOP #068 - Montes Alpes & Vallis Alpes

Spectacular boundary of the Mare Imbrium Basin, with heights from 1.8 to 2.4 km ranging up to 3.6 for the great Mont Blanc. The impressive Vallis Alpes runs perpendicular to the prominent Montes Alpes, making this one of the most picturesque areas of the Moon. The valley is a wide rift valley, 180 km in length that links Mare Frigoris to Mare Imbrium.

Location: 46.0 N 3.0 E-3.0 W    Origin: Impact and Volcanic     Length: 250 km (Montes Alpes), 166 km (Vallis Alpes)     Rukl: 12, 4    
Type: Mount and Valley

Seeing: Good (3)
Transparency: Good (3)

R1: The shadows extending from Montes Alpes were quite long in some areas. Refer to the sketch below.
R2: Vallis Alpes was quite wide and very easily identified; its shadow was on the northern edge.
R3: Cassini had low walls and two craters - A and B - were on its floor. Theætetus was also low-walled SE of Cassini. Refer to the sketch below.

C1: The Promontorium Agassiz and Promontorium Deville were sketched. They in essence formed a shallow bay on Mare Imbrium. Mont Blanc was to their north.
C2: The sinuous rille was seen; it had a varying width away from straight rille. Shadow on its north rim.

IWLOP #069 - Aristillus & Autolycus

IWLOP #069 - Aristillus & Autolycus

Two outstanding craters in the Mare Imbrium that contrast nicely in size. They are both Copernican era impacts with Aristillus featuring a notable ejecta blanket.

Location: 33.9 N 1.2 E    Origin: Impact    Size: 55 km (Aristillus), 39 km (Autolycus)    Rukl: 12    Type: Complex Craters (CC)

Objects: Aristillus, Autolycus, Sinus Lunicus, Luna 2 landing, and Aristillus A, B, C, & D
Others Identified: Alpetragious, Alphonsus, Ammonius, Arzachel, Herschel, Nonius, Ptolemaeus, Thebit, Walther


Location: Home
Date: 2018-09-17
Time: 8:05 PM ADT
Equipment: 10" Meade SCT
Eyepiece: 10mm + x2 Barlow

Magnification: x500
Seeing: Good (3)
Transparency: Good (3)

R1: The ejects blanket of Aristillus rays out from its high crater sides. Autolycus doesn't appear to have ejecta to the same degree and is shallower than Aristillus. 
R2: The rays from Aristillus were spread over the adjacent areas of Autolycus and reached to Archimedes.
R3: Sinus Lunicus was to the west. It's shores appeared to be defined in the triangle formed by Autolycus, Aristillus and Archimedes. I questioned whether Montes Spitzbergen created part of the border with Mare Imbrium. The Luna 2 landing site was SW of Autolycus and E of Archimedes.

C1: Very small secondary craters (A, B, C, D) were located near Aristillus and appeared to be located along the ejecta lines / rays.

IWLOP #073 - Regiomontanus & Purbach

IWLOP #073 - Regiomontanus & Purbach

Regiomontanus is a pre-Nectarian Era crater. Note it's severely eroded walls and elongated shape. Purbach is a prominent pre-Nectarian Era crater with a poorly defined and eroded western wall.

Location: 28.4 S 1.0 W    Origin: Impact     Size: 126x110 km (Regiomontanus), 118 km (Purbach)    Rukl: 55     Type: Complex Craters (CC)

Objects: Regiomontanus, Purbach

 

Observation 1:
Location: Home

Date: 2018-09-17
Time: 7:40 PM 
Equipment: 6" Dobsonian
Eyepiece: 10mm

Magnification: x120
Seeing: Very Good (2)
Transparency: Good (3)

R1: Regiomontanus was located north of Walther. Regiomontanus A was located on its north floor. At x120 magnification, the centre peak was a little off-centre and a few crater-like formations comprised the terrain of that area. Regiomontanus appeared lower in elevation than did Walther.
R2: Purbach had ridges highlighted on the one side and tall shadows on the other. Crater G had certainly impacted its northern rim. At the north end of Purbach, the shadows showed like two lines (not straight) going from near the rim to almost the centre. Wasn't sure if it was craters on the floor.

Observation 2:
Location: Home

Date: 2021-04-19
Time: 8:30 PM 
Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm with 82° FOV + x2 Barlow

Magnification: x1060
Seeing: Good (3) - Fair (2)
Transparency: Very Good (4)

The line of craters on Purbach's floor is what caught my attention, in combination with the line of craters in Regiomontanus.

NOTE: The shadows that showed like two lines going from near the rim to almost the centre in the previous observation may have been the east and west walls of the craters on the floor.

R2: Purbach's north wall was either terraced quite well or was slumped (?). Crater G was completely in shadow on its floor; its impact on Purbach's north wall was substantial. Tonight there appeared to be 2 shallow craters in a line southward from G above crater W; small crater A was below and in line with them. Two craters (U and S) impacted the south wall. Didn't see this detail in 2018.

IWLOP #074 - Arzachel

IWLOP #074 - Arzachel

Arzachel is a spectacular Imbrian Era crater with sharply defined, deep-terraced walls. It makes a nice trio with Alphonsus and Ptolemaeus to the north.

Location: 18.2 S 1.9 W    Origin: Impact     Size: 97 km     Rukl: 55     Type: Complex Crater (CC)

Objects: Arzachel, Arzachel E & F, Alpetragius, Thebit & Thebit A

Location: Home
Date: 2018-09-17
Time: 9:30 PM ADT
Equipment: 10" Meade SCT
Eyepiece: 1 mm + x2 Barlow

Magnification: x500
Seeing: Very Good (4)
Transparency: Good (3)

R1: Arzachel had an off-centre peak, broad wall, and two valleys in shadow. The depression valleys E and F on the southeastern and southwestern walls were in the shadows and not easily seen, even at this magnification.
R2: Alpetragius had its crater floor seemingly filled with a volcano-looking peak.
R3: Thebit and Thebit A were to the southwest of Arzachel. The smaller Thebit A had impacted near Thebit's NW rim.

C1: The low hills on the south and southwest floor of Arzachel were observed.
C2: The accurate rille was noticed because its shadow was darker than the shadow cast from the rim onto the crater floor.

Time: 9:30 PM ADT
Equipment: 10" Meade SCT
Eyepiece: 10mm + x2 Barlow

Magnification: x500
Seeing: Very Good (4)
Transparency: Good (3)

R1: Alphonsus' central peak was located adjacent to a rise or rille. 
R2: Ptolemaeus has a smooth floor and the small circular crater Ammonius was located in it; it had no noticeable shadows on Ptolemaeus' floor. 

Observation 2:
Location: Home

Date: 2021-03-22
Time: 9:30 PM ADT
Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm with 82° FOV 

Magnification: x530
Seeing: Very Good (4)
Transparency: Good (3)

R1: Herschel is north of Ptolemaeus and is quite deep by comparison, and is especially deeper than the shallow Spörer to its north.

C1: There are three distinct dark patches in the NE, SW and SE. 
C2: The crater Flammarion has a break in its southern rim; the northern rim is non-existent. Rima Flammarion began at crater C and headed north of Mosting A through a valley in its rim.

NOTE: Research conducted after this session indicated the dark patches were ash deposits from fire fountains that ocurred after Alphonsus was formed.

No wind or cloud.

Although moonset wasn’t until near midnight, the Moon disappeared from our view by 9:30 PM due to our southerly treeline. I knew I had a limited window to see the Moon before it disappeared.

My focus was on the NE portion, especially Montes Caucasus. Identified Calippus and noted 3 small volcanic-looking cones SE of the range. Also noted a line of brightness in the floor of Mare Serenitatis; identified it as Dorsa Smirnov.

I then went southward to Mare Tranquilitatis where I found a familiar pattern of craters near its chores in the SW – Manners, Ritter, Sabine & Dionysius.

Rimae Hypatia was also identified but I didn’t look at it in detail.

Montes: Caucasus, Rimae Hypatia

Maria: Frigoris, Serenitatis, Tranquilitatis

We had over 200 people come visit the numerous telescopes set up on the board walk and despite being downtown Halifax we were able to sow visitors Jupiter and other objects easily seen through the urban light pollution. It was a warm night, no breeze or clouds. Through the telescope, the stripes on the planet appeared diagonal to the horizon. I sketched Jupiter with its moons before it disappeared behind one of the buildings. Ganymede, Callisto and Europa formed a triangle on one side of the planet and Io was alone on the other.

Time 1: 8:00 PM - 11:50 PM  ADT
Time 2: 3:50 AM - 5:05 AM ADT

Equipment: Visual + Binoculars, 10x42 IS
Transparency: Excellent (5)
Seeing: Excellent (5)
Temperature: 12º C - 10º C
SQM: 21.64 - 21.89

This was the second year we camped at this location with Dave and Christine where we have our "private" star party.

No wind. No dew. The Lake was dead calm which allowed for the perfect reflection of the stars. No clouds but the horizon to the north was certainly better than to the S and SW; it did improve as the evening progressed.  

Milky Way
Time: 8:00 PM - 4:16 AM ADT
Equipment: Visual + Binoculars 

Just wanted to highlight a segment of this observing session to the Milky Way. It was seen as a faint nebulosity across the sky around 8 PM and by 4 AM the Great Rift was clearly defined all the way from Cygnus through Vulpecula to Aquila that was now setting. A row of very bright stars seemed to be falling down through the Rift but I did not identify what they were.

Observation Time 1:

Ophiuchus + Serpens Caput + Serpens Cauda
Time: 7:55 PM - 8:15 PM ADT
Equipment: Visual + Binoculars 
S&T Chart Reference (Ophiuchus): 54, 56
S&T Chart Reference (Serpens Cauda): 54, 56
S&T Chart Reference (Serpens Caput): 65,67

Ophiuchus: I located the stars of this huge constellation above Scorpius, this protector of Hercules. Easily saw the curve formed by Nehushtan, Sabik (η), ζ, Yed Posterior (ε) and Yed Prior (δ). Looked above this to find Rasalhague (α), Cebalrai (β), Marfik (δ) and κ.

Serpens: I then went eastward from Yed Prior to follow the stars comprising the constellation Serpens Caput (the head of the snake). Going to the other side of Ophiuchus, I went westward and followed the stars from nu Ophi to Alta (theta) - the snake's tail.

Once identified, I pointed out all 3 constellations to Jerry and explained how Ophiuchus was the snake charmer.

Serpens Caput
Serpens Cauda

Jupiter
Time: 8:10 PM ADT
Equipment: Visual + Binoculars 

Readily located visually. Used my binoculars to view 3 of the 4 Galilean moons - Europa, Ganymede and Callisto.

M8 (Lagoon Nebula) + M20 (Trifid Nebula)
Time: 8:30 PM ADT
Equipment: Visual + Binoculars 
S&T Chart Reference: 67, 69. I

Attempted to see M8 visually but that was not possible. However, it was easily located and viewed with my binoculars. The oval-looking nebula and about 5 bright stars were readily identified.

In the same FOV was M20. I did not view it more closely to determine if there was any "structure to the cluster.

Keystone of Hercules + M13 (Hercules Globular Cluster)
Time: ~ 9:00 PM ADT
Equipment: Visual + Binoculars 

Sometime after 9:00 PM, I noticed the Keystone overhead so pointed my binoculars at η Herculis and saw M13 as a grey fuzzy. Could not see the specific structure of the globular cluster.

International Space Station (ISS)
Time: 9:57 PM ADT
Equipment: Visual + Binoculars 

The ISS came into view visually as I looked up at Corona Borealis. Very bright and easy to follow so used my binoculars. I could actually see two distinct wing structures. 

1 = first sighting of ISS
2 = loss of sighting above Cassiopeia as the ISS moved past the treeline

   

Sagitta
Time: 10:14 PM ADT
Equipment: Visual + Binoculars 

I had attempted to find this last evening but had failed. Tonight, however, after some effort, I did find all 4 stars. Yay!

 

Pisces Austrinus
Time: 10:16 PM ADT
Equipment: Visual 
S&T Chart Reference: 76, 77, 78, 79

Fomalhaut was the star that brought my attention to this area of the sky.  It was about 5º above the SE horizon and was very bright in the evening sky. All 10 stars of the constellation were easily seen visually; I did not use my binoculars. 

Observation Time 2:

Taurus
Time: 4:00 AM ADT
Equipment: Visual + Binoculars 
S&T Chart Reference: 12

Had to wait until 4 AM for Taurus to rise above the tree line. θ1 and θ2 appeared one above the other, pointing towards 11:30 o'clock.

Auriga
M36/NGC 1960,  M38/NGC 1912,  M37/NGC 2099
Leaping Minnow asterism
Comet 21P/Giacobini-Zinner
Time: 4:18 AM
Equipment: Visual + Binoculars 
S&T Chart Reference: 12

I located Auriga by first locating Capella, then identified the major stars of the constellation.

I began to "Messier hop" beginning with the "Leaping Minnow," an informal grouping of stars that includes 14, 16, 17 and 19 Aurigae. I then found the grey fuzzies of M38, M36, then M37.

Comet 21P/Giacobini-Zinner appeared as a vertical smudge west of M37. In binoculars, there was no distinction between the comet and its tail. However, Dave had a small telescope with him on the beach through which the distinction could be made.

   

Lepus
Time: 4:18 AM
Equipment: Visual 
S&T Chart Reference: 16

This morning, Lepus was easily identified below Orion. All major stars in the constellation were seen and identified. I pointed out this constellation to Jerry. 
I noted that the first time I saw Lepus was in Chile but it was at a different orientation, i.e., the line of μ to ε was parallel (not perpendicular) to the horizon.   

   

M11 (Wild Duck Cluster)
Time: 4:40 AM
Equipment: Visual + Binoculars 
S&T Chart Reference: 67

The Milky Way was so b right, its central dark lane was clearly discern le. I knew that M11 was located near Scutum and the semi-circle of stars beside it.  I visually located the star cloud then found the small grey fuzzy adjacent to the golf club head with my binoculars. Dave also had a view of it in his telescope.

Gemini + M35
Time: 4:48 AM
Equipment: Visual + Binoculars 
S&T Chart Reference: 23, 25

Castor and Pollux were lying on their side as they rose above the treeline. Sky was so clear we could make out the stars in the arms and legs of both of the Twins. The constellation was immediately below Auriga so it was easy to "go down" the line of Messier from 38 to 36 to 37 to M35 at Castor's toe. I had also used M35 as a landmark en route to the comet from another direction.

Orion + M42 (Orion Nebula) + M43 (De Mairan's Nebula / NGC 1982)
Time: 4:52 AM
Equipment: Visual + Binoculars 
S&T Chart Reference: 14, 16 B

I first noticed this constellation was once again visible after locating theta1 and theta2 in Taurus. What a pleasant sight! The big was so clear that all the stars ere brilliant and the nebulosity in the sword (M42 and M43) was quite clear visually and with binoculars.

Light breeze. Occasional cloud in various parts of the sky all evening. Very loud crickets this evening. Peter & Ilias Hurley, Jerry Black, and several others were there.

Jupiter (in Libra)
Time: 8:40 PM ADT
Equipment: Binoculars 

I could not locate all 4 moons. Could only locate 1 this evening that I assumed was Callisto.

   

M7 (Ptolemy's Cluster)
Time: 9:22 PM ADT
Equipment: Visual + Binoculars 
S&T Chart Reference: 32, 43

I specifically sought this out as I hadn't observed it in a while. Visually, could make out a grouping of stars lower to the west of the Teapot. The large open cluster filled my FOV with numerous stars clearly visible.

Stars of Ursa Major
Time: 9:50 PM ADT
Equipment: Visual + Binoculars 
S&T Chart Reference: 32, 43

I was showing Ilias and Peter the night sky later in the evening. Using my telescope, we first viewed the optical double Mizar and Alcor in Ursa Major. Used the handle of the Big Dipper to locate Mizar then enjoyed the view in the eyepiece.

Mizar A was larger and brighter than Mizar B. Alcor was easily seen below Mizar in the telescope view. A triangle was formed by Mizar-Alcor-HD116789. A line of stars to the side of this triangle were identified:

  1. TYC3853-0228-1
  2. GAIA 1565097112139144832
  3. TYC3853-0175-1

   

   

M8 (Lagoon Nebula)
Time: 10:05 PM ADT
Equipment: Visual + Binoculars + Telescope & 10 mm eyepiece
Magnification: binoculars x10, telescope x250
S&T Chart Reference: 67, 69, I

I showed Ilias and Peter two views of the Lagoon Nebula:

a) Binoculars: Used Kaus Australis and the Teapot spout to locate it. Saw M8 as an oblong nebulosity with a line of 4-5 bright stars with a couple more above it

b) Telescope: Jerry showed us through the telescope. We could then see two parts to the object - a small nebulosity with a line of stars plus the adjacent denser nebulosity with numerous stars. Such a difference from the binocular view.

M13 (Hercules Globular Cluster)
Time: 10:20 PM ADT
Equipment: Visual + Binoculars
S&T Chart Reference: 52, 54

I showed them the Keystone of Hercules almost directly overhead, then showed them how to find it 1/3 of the way between η Herculis and ζ Herculis. Success! They found the small grey fuzzy.

    

M31 (Andromeda Galaxy)
Time: 11:15 PM ADT
Equipment: Visual + Binoculars + Telescope with 30 mm eyepiece
Magnification: binoculars x10, telescope x83
S&T Chart Reference: 3, 72

I explained how to find it using Cassiopeia and by using the Square of Pegasus/Andromeda. Could see it visually and then a much better view through binoculars. Jerry then showed us the view through the telescope where the bright centre of the oval galaxy was observed.

Clear skies to start then high thin clouds began to obscure the perfect views of craters. 

 

 

 

Poncelet appeared to have little or no rim on the S and NE. Only a bit of shadow cast on its north and west rims. There was a shadow from a peak.

Because of the angle of viewing, Pascal and Brianchon appeared to be joined. The SW edge was rougher compared to the others and a peak’s shadow was seen in both.

 

Grimaldi had a high side to the NW causing shadows towards Riccoli. To the SE rim, 3 shadows were cast (peaks?) along the rim.

 

Going away from the SE rim were 4 very small craters that led me to Sirsalis and Sirsalis A. There was a dark line SE of Sirsalis – Rimae Sirsalis.

 

In referencing the S&T Moon Map, I realized the bumpy terrain between Grimaldi and Sirsalis was Lacus Aestatis.

 

Schikard had 2 craters very visible in the SW limb. The NE rim had a rough area between it and Lehmann. Its floor was a little darker than its surroundings.

Wargentin had a crater off-centre that appeared to have a ridge running from rim to rim over or very close to the crater. The rim was more evident on the side of the Moon’s SW limb (not the terminator). To verify the rim, I observed it twice.

Phocylides had a large crater on its S-SW rim and its NE rim.

Nasmyth was barely discernible; its NE rim the only evidence that it was beside Phocylides and Wargentin.

Lacus Excellentiae was seen but couldn’t see Clausius.

Maria: Lacus Aestatis, Lacus Excellentiae, Oceanus Procellarum

Mountains: Vallis Inghirami, Rima Sirsalis

Craters: Cavendish, Fourier, Grimaldi, Henry, Henry Frère, Hevelius, Inghirami, Lacroix, Lehmann, Liebig, Mersenius, Sirsalis, Sirsalis A, Lohrmann, Nasmyth, Phocylides, Schikard, Vieta, Wargentin.

Explore the Moon (Telescope) - September 1/2, 2018

I was working on both the ETM (telescope version) but also spent time in general observing and on IWLOP objects. Also viewed Jupiter and its 4 visible moons.

Lunar Phase: Waning Gibbous (71.0%)
Q-Day: +1

Moonset: 12:45 PM       Moonrise: 11:15 PM
Sunrise: 6:38 AM           Sunset: 7:53 PM

Location: SCO
Date: 2018-09-01 - 2018-09-02
Time: 9:00 PM - 2:00 AM
Temperature: 16º C - 15º C
SQM: 21.07 @ 10 PM, 20.88 @ 10:28 PM
Equipment: Celestron 6" Dobsonian, eyepiece unknown

Magnification: unknown
Transparency: Very Good (4)
Seeing: Very Good (4)

Clear skies to start but clouds came in for about an hour around 10 PM then cleared off to a clear sky again. Because of the treeline at SCO on the driveway side of the Warm Room (best view of the Moon after Moonrise), I didn’t start observing until 12:02 AM. Wanted to find Apollo 12 & 14 landing sites but the iPhone App didn’t cite them. However, I did spend time on the shores of various maria – Cognito, Frigoris, Imbrium, Nubium, and Oceanus Procellarum.

Also of note was how heavily cratered the southern limb was. Didn’t attempt to identify them at this time as the craters on the maria and the related mountains caught my attention.

Found 3 “new-to-me” features: Regiomontanus, Mons Pico, Bliss.

Downside to the 3-hour observing session was that I didn’t fully explore the landing sites for Apollo 12, Apollo 14, and Ranger 7. Maybe tomorrow night/AM?

Maria: Cognito, Frigoris, Imbrium, Nubium, Oceanus Procellarum, Palus Putredinus

Mountains: Alpes, Apennine, Carpatus, Mons Pico & Pico B, Riphaeus, Tenerife, Vallis Alpes

Craters (East of Mare Nubium): Albategnius, Arzachel, Blanchinus, Herschel, Le Caille, Ptolemaeus, Purbach, Regiomontanus, Thebit, Werner.

Craters (East Shores of Mare Nubium): Archimedes, Aristillus, Autolychus, Cassini

Craters (North of Mare Nubium): Bliss, Lansberg, Plato, Reinhold

Other Craters: Copernicus (south of Montes Carpatus), Eratosthenes (southern Mare Imbrium).

Tried to locate Stadius but wasn’t successful. Contacted Dave Chapman as to how best locate Stadius. He described it as a “ghost crater”. It’s old and has been flooded by lava when the mare formed so its walls are not too high, and it has been eroded by impacts so it’s a bit camouflaged. The trick is to look for it when it’s near the terminator (tonight or early tomorrow AM?) when the low sun angle will cast it in a more obvious relief.

I had a new-to-me 10" Meade thanks to a friend in Ottawa. This was my first "oh, WOW!" moment with it. 

M8 was seen fully divided into 2 distinct segments:
   * One side had 4 bright stars in a denser looking portion.
   * The other portion was 5 lines of stars of varying magnitudes.

Absolutely beautiful - and amazing.

I had spent some time looking at the Moon to determine what features to observe. I managed to complete IWLOP #84 - Mons Pico & Montes Teneriffe in Mare Imbrium. Also observed some features needed for the Explore the Moon (telescope).

Jupiter (in Libra)
Time: 9:00 PM
Equipment: Telescope

Jupiter was quite bright although not as bright as Venus or Mars. Could easily see Callisto but Io took much looking to find it. There was a bulge on Jupiter's surface that could have been Ganymede or perhaps just a very bright spot that made it look like a bulge or moon.

  

Saturn (In Sagittarius)
Time: 9:26 PM
Equipment: Telescope 

Saturn was high in the sky above the Teapot's spout and M8. Very Bright. Was able to determine one moon - Titan. Initially I thought it was Phoebe but it wasn't far enough away from the planet to be so. Could not make out any moons closer.

Satellite
Time: 9:45 PM
Equipment: Telescope + Binoculars 
A satellite flew through my telescope FOV from east to west through the lid of the Teapot. I used my binoculars to follow it as it disappeared in the Milky Way.

α Perseus Cluster
Time: 11:00 PM
Equipment: Binoculars 
S&T Chart reference: 2, 13

While waiting for Capella to rise above SCO's horizon to better see Comet P21, I noticed Perseus was up so used my binoculars to view this gloriously open and bright cluster.

M8 (Lagoon Nebula)
Time: 10:28 PM - 10:40 PM
Equipment: Telescope
S&T Chart Reference: 67, 69, I

Seeing M8 with a telescope is very different than through binoculars. What I had seen on September 3, 2016 was 5 or 6 bright stars in a dense clump that formed a line of stars and the less dense clumps filled the mottled brightness above it. The telescope view seemed to have 5 or 6 vertical rows of stars that remind me of the α Perseus Cluster.

Also refer to Messier Catalogue - M008 (Lagoon Nebula) - September 1, 2018

   

Meteor
Time: 1:30 AM
Equipment: Visual
A very bright meteor lasting 1.5 seconds. Began whitish and ended in bright green as it travelled through the region of Draco.

No wind or clouds or dew. Hazy skies due to either Moon or high-altitude smoke (?). Saw the Moon coming through the grape vines on our shade structure in the East. Knew it would be at least another hour before it would be high enough to view.

12:07 AM:
Moved the Dobsonian to our unused veggie garden. Although the terminator was clearly seen, I focused attention on Tycho. It was pretty much bleached out with the Sun’s light but there was a slight shadow on Tycho’s western rim (refer to sketch).

It was then I referred to the S&T Field Map of the Moon to identify craters. Took me about 15 minutes to orient myself to the upside-down and what I was seeing due to Moon phase. I noticed Apollo 17 on the map so decided to focus on that area.

To get to Apollo 17, I located Le Monnier then navigated along the shores of Mare Serenitatis. The name of the landing site is the Taurus-Littrow Valley. Posidonius had 2 craters seemingly in its rim and another just outside. I drew what I saw then identified the following features:
a)     Maria, etc.: Serenitatis, Sinus Amores, Tranquilitatis
b)     Mountains: Mons Vitruvius, Montes Taurus
c)     Craters: Chacornac, Daniell, Gardner, Le Monnier (west edge not clearly defined), Littrow, Luther, Maraldi, Posidonius, Römer, Römer A, Tycho, Vitruvius

Coordinates for Apollo 17:
ALSE: 20.1923 N, 30.7655 E
Lunar Module (LM) 20.1911 N, 30.7723 E

Coordinates for Apollo 11”
LRRR: 0.673445 N, 23.47307 E
Lunar Module (LM): 0.67416 N, 23.47314 E

1:10 AM:
SQM: 18.66. Temperature still at 18° C. Attention focused on Apollo 11 landing site in Mare Tranquilitatis, sightly NE of the crater Moltke.

To get to Apollo 11, I went from Vitruvius to the craters Plinius to Ross and Maclean to Arago & Manners. Followed the curve formed by 2 small craters (Ritter and Sabine) to Moltke and the landing site.
a)     Mare: Tranquilitatis
b)     Mountains: Hypatia, Rimae Hypatia
c)     Craters: Arago, Maclear, Moltke, Plinius, Ritter, Ross, Sabine, Vetruvius.

NOTE: Looked up the lunar coordinates for the two Apollo missions later.

1:29 AM:
SQM: 18.66. Temperature still at 18° C, no wind, no clouds but still a bit hazy. Decided to focus on the shorelines of Mare Nectaris where if found the craters:

  • Fracastorius (no crater edge on it north border)
  • Rosse (in the Mare)
  • Beaumont, Catharina, Cyrillus, Theophilis (west of Mare Nectaris)
  • Piccolomini (south of Fracastorius)

I then headed north back to the Apollo 17 landing site, to the crater Daniell just above Posidonius, then on to Hercules and Atlas. Hercules was very visible, but Atlas was now mostly beyond the terminator.

Mare: Lacus Somniorum

Other craters viewed:

  • Bürg (west of Hercules in Lacus Mortis)
  • Mason & Plana (SE of Bürg)
  • Grove (SE of Mason)
  • Williams (E of Mason)

General Session - August 25, 2018

Planets: Jupiter, Mars, Venus
Red Moon
Red Sun
Constellation: Cassiopeia
Asterism: Big Dipper
Stars: Mizar A & B, Alcor

Location: Blomidon Provincial Park, NS
Date: 2018-08-25
Time: 8:00 PM - 10:05 PM ADT
Equipment: 6" SkyWatcher 150P Dobsonian telescope + 10 mm eyepiece
Magnification: x120

Transparency: Fair (2)
Seeing: Fair (2)
Temperature: 16º C
Light breeze with smoke in the higher atmosphere from the western Canada forest fires.

Jerry and I were camping at Blomidon along with our two daughters and their families. I was able to show both our 5-year-old grandson and 2-year-old granddaughter a view of the Moon and Jupiter through the 6" Dobsonian we had brought with us. Our grandson particular was quite excited about identifying things he saw in the sky - naked eye and through the telescope, not to mention in SkySafariPro.

Jupiter, Mars & Saturn
Time: 8:00 PM - 8:30 PM
Equipment: Visual + Telescope with 10 mm eyepiece

Our grandson pointed to Mars and asked what the name of that "star" was. When he was told it was actually the planet Mars, he was so excited! He ran to his parents shouting, "I saw the star Mars!"

Jupiter was west of Mars and was bright enough to point it out to him. Also showed him Venus that was just about to set in the west; he was so excited to see his 3rd planet for the evening.

I told him he had actually seen 4 planets and he correctly identified "Earth" as the fourth. Smart boy!

Cassiopeia
Equipment: Visual
Because our grandson had stars on his bedroom ceiling, he referred to this constellation as his, the "William" constellation - because of its shape. He was thrilled to see it for real.

Red Moon. Red Sun.
Equipment: Visual
Moonrise: 8:00 PM ADT
Sunset: 6:30 PM ADT
Our grandson asked why the Moon and Sun were quite red in colour. It was explained that b
ecause the smoke from the western Canada forest fires was in the air between us and space, it gave them the reddish colour. We couldn't see many stars naked eye this evening but the planets, Moon and Sun stood out. 

Big Dipper + Mizar A & B + Alcor
Time: 9:30 PM 
Equipment: Telescope + 10 mm
Magnification: x120

Because our grandson had stars on his bedroom ceiling, he knew the Big Dipper when I pointed it out to him. I also told him the centre star in the handle was special because it was a double star. I showed him on SkySafariPro what it would look like close up then showed him through the eyepiece. Wow.

Warm night. High fog and cloud impeded clear viewing of any object for any length of time. Dave Chapman arrived around 7:45 PM to collimate the telescope. He was unhappy with the attempt to do so at Kejimkujik, so came here to determine if it could be done. Success! Collimation achieved. He also brought his eyepieces, and we tried his Televue Ethos 8 MM. The clarity was wonderful!

After he left, I returned to my 25 mm eyepiece and between episodes of fog/cloud cover, drew the Sinus Iridum. What captured my attention was the brilliance of the face of the semi-circular Montes Jura. The pure white edge contrasted to the adjacent terrain. The shadows of the two promontories were evident.

There were two faint craters to what would be the NE, one of which might have been Maupertuis or just the two smallest craters nearest Promontorium Laplace. Needs a further investigation.

Did not look for other features due to limited time during sucker hole opening. Gave up at 9:50 PM.

Constellation: Ursa Major
Planets: Saturn
Moon

Location: Home
Date: 2018-08-20
Time: 9:00 PM - 11:30 PM ADT
Equipment: 6" SkyWatcher 150P Dobsonian telescope + eyepieces (10 mm, 25 mm wide angle, 30 mm with 2" adapter)
Magnification: x48

Moon
We were playing with my newly-acquired 6” Dobsonian (gifted to me after the Kejimkujik DSW). Aligned the finder scope with the tube and ‘pushed’ it to the Moon in the E-SE sky. It provided me an upside-down view of the Moon, but lunar features were still easily identified with the mirror-reverse lunar maps.

Refer to Explore the Moon (Telescope) - August 20, 2018 for details.

Also completed this evening was IWLOP #100 - Bullialdus.

Saturn
Time: 9:20 PM ADT
Equipment: telescope + 25 mm eyepiece
Magnification: x48
Saturn was in the SE sky above our neighbour's back shed. The telescope very clearly provided a view of Saturn and its rings. No ring separation but could see a gap between the planet and its ring structures. This view, however, did vary with the changing atmosphere.

Ursa Major
Time: 10:30 PM ADT
Equipment: Telescope + 10 mm, 25 mm, 30 mm eyepieces
S&T Chart Reference: 31, 32, 33, 43, F
Magnification: x120, x48, x40

In all 3 eyepieces, Mizar was seen asa double star. As in 2016, there was a third star that formed a triangle with Mizar and Alcor; I later identified it as HD116798.

Below HD 328226 was a line of 4 stars, ranging in magnitude of 11.1 - 13.6 (#1 - #4 in the sketch).

The identified HD238226 and a fainter magnitude 12.9 star to its right as GAIA 1563780481323958784 (#5 in the sketch). Quite the handle!

Saw this again when observing Kies and Mercator (IWLOP #101 - Kies, Mercator & Campanus). Walls were very terraced and had at least 2 central peaks. Rim is not rounded completely; perhaps the rim has collapsed partially in some sections (?). The north rim didn't look as defined as the others; not sure if due to crater formation or the lighting on the Moon.

The 78.6% Waxing Gibbous Moon was going to rise at 11:21 PM ADT. Jerry and I were just beginning to see a brightness in the east. 

Teaspoon
Time: 10:50 PM ADT
Instrument: Visual 
S&T Chart Reference: 66, 67

I had read about this on the RASC discussion list or in one of the RASC newsletters or magazines in the spring. This was the first time I actively looked for it.

We were searching for Mars adjacent to Capricornus. With Sagittarius so high in the sky, I decided to look for the Teaspoon. There it was. We could easily see ρ1, 43, π, ο and ξ2. Did not have binoculars with us so couldn't look for the double star of 43, nor the binaries ρ1/ρ2 and ξ1/ξ2 Next time.

Mars above Hog Island, Saturn above the Teapot, Jupiter in Libra, Venus in Leo. Red dotted line is the Ecliptic.

No clouds and only a light breeze across the water. Hubby and I were viewing the 4 planets (Mars, Saturn, Jupiter, Venus) because of their alignment on the ecliptic - me visually and with binoculars, him with his camera. It was a quiet calm evening with the planets and  Moon providing beautiful reflections in the Lake.

Venus (in Leo)
Time: 9:24 PM + 10:24 PM ADT
Instrument: Visual 

Observation #1 @ 9:24 PM:
Venus was about 10º above the western horizon just below ν Virgo and Denebola.

Observation #2 @ 10:24 PM:
Venus was only 1º - 2º above the horizon and appeared red. Beautiful reflection of the planet on the Lake.

Mars
Time: 9:24 PM ADT
Instrument: Visual 
Mars showed up very red and very bright above the eastern shore of Hog Island in Kejimkujik Lake, approximately 10º above the horizon.

Saturn (in Sagittarius)
Time: 9:54 PM ADT
Instrument: Visual + Binoculars 

On this night, Saturn was 3º - 4º above & NW of Kaus Borealis. I couldn't see the rings with the binoculars. Only saw the planet as slightly elongated in the middle latitudes.

Jupiter (in Libra)
Time: 9:54 PM ADT
Instrument: Visual + Binoculars 

Used my binoculars to view Jupiter's moons and its proximity to α Librae, approximately 10º. Could only see 2 of the 4 Galilean moons; I later identified them as Callisto and Ganymede.

Moon at 11:32 PM ADT
Moon reflections at 11:36 PM ADT

Meteor
Time: 10:18 PM ADT
Instrument: Visual
A meteor went through Aquila and last approximately 1 second. Not really brilliant but still quite bright.

 

 

 

M7 (Ptolemy's Cluster)
Time: 10:24 PM ADT
Instrument: Visual + Binoculars 
S&T Chart Reference: 67, 69

Noticed a patch of bright light sky just west of Kaus Australis. Used binoculars to identify the cluster. It's a beautiful open cluster, site bright and filled my 6.5º FOV. Seven to eight of the brightest stars looked like they foreman "H" albeit an artistic one.

Cygnus + Coathanger / Collinder 399 / Brocchi's Cluster
Time: 10:28 PM ADT
Instrument: Visual + Binoculars 
S&T Chart Reference: 65

Found Deneb then identified Cygnus aka the Northern Cross. Followed the line from Deneb to Sadr to ν to Albireo. Used my binoculars to locate the double star Albireo:
   - β Cygni A was the large yellow-gold and
   - β Cygni B was the smaller bluish component in close proximity

I then put down my binoculars for a moment to visually locate Albireo and the possible location of the Coathanger. Put my binoculars up and there it was! All of the stars in the hanger and hook were visible.

Teapot + Saturn
Time: 10:30 PM ADT
Instrument: Visual
All of the Teapot was well above the horizon. Kaus Australis was about 8º - 10º above the southern horizon. All 8 stars of the asterism easily identified. 

Saturn was 3º - 4º above & NW of Kaus Borealis.

 

Scorpius
Time: 10:30 PM ADT
Instrument: Visual
S&T Chart Reference: 56, 58 J

All of Scorpius was well above the horizon; theta was at least 10º above the horizon if not a little more. Could see Antares in all of its redness quite well. Could also identify most of the stars in the stinger and all of the stars in the constellation above Antares except nu and rho. Always seem to have difficulty identifying / locating theses two. 

Meteor
Time: 10:54 PM ADT
Instrument: Visual
A meteor was seen between Ophiuchus and Serpens Caput, in essence going up the laneway between them. It travelled from there to just past the height of the serpent's head before disappearing.
 

M5 / NGC 5904
Time: 11:04 PM ADT
Instrument: Visual + Binoculars 
S&T Chart Reference: 65, 57

Found M5 after locating Ophiuchus and Serpens Caput. Used the two stars δ Ophiuchus and μ Ophiuchus to find M5. Fairly faint fuzzy, but did see it and more readily using averted vision.

Clear skies and no cloud. We had our chairs on the Lake Superior shoreline within inches of the water. Mama duck and 7 ducklings swam past us within arm's reach - their fear of humans was not evident.

Sitting on the narrow shore, we watched as the sun set over the Sleeping Giant and the stars begin to appear. A beautiful night on the shores of Lake Superior.

Light wind at this time of evening. The few clouds earlier in the evening have disappeared.

Earlier in the day when trying to set up camp, we had to open both flies of the tent to allow the wind to go through it during set it up (otherwise it became a kite) and weighed down the floor with camp gear to keep the tent from blowing off the mountain. Too windy for a camp stove so had a sandwich supper inside the tent.

Venus (in Virgo)
Time: 9:35 PM CDT
Instrument: Visual 

Viewed Venus naked eye. Found it 15º above the WSW horizon below β Virgo (Zavijava).

Jupiter (in Libra)
Time: 9:50 PM CDT
Instrument: Visual + Binoculars 
S&T Chart Reference: 46, 57

Jupiter could easily be found visually in the SW sky. My binoculars allowed me to find all 4 Galilean moons - Io, Ganymede, Callisto and Europa. Jupiter was located less than 5º from α Librae at approximately 2 o'clock to the star.

   

Scorpius
Time: 9:50 PM + 11:00 PM CDT
Instrument: Visual + Binoculars 
S&T Chart Reference: 56, 58, J

Observation #1 @ 9:50 PM:
Used my binoculars to view Antares; this star had initially caught my attention due to its definite redness and the binocular view showed the colour very well. I was also to see the blue τ Scorpii / Al Naiyat. Visually, I located Deshubba. I found it difficult to locate the other stars in the constellation due to the lightness of the sky at this time.

Observation #2 @ 11:00 PM:
Antares was still visibly quite red. Once again located Al Niyat and Dschubba but also visually located Graffias and π Scorpii. Used my binoculars to locate ω1 Scorpii and ω2 Scorpii near Graffias; very easy to see this bright pair.

   

M11 (Wild Duck Cluster)
Time: 10:20 PM CDT
Instrument: Binoculars  
S&T Chart Reference: 67

Looked for the semi-circle of stars above the Teapot and used binoculars to locate M11 (as the golf ball next to the golf club). Could make out the brighter centre with fading edges of the globular cluster.

Summer Triangle (DAVe)
Time: 10:28 PM CDT
Instrument: Visual + Binoculars 
Visually located all 3 stars of the asterism - Deneb, Altair and Vega. Used my binoculars to look at Vega and Lyra's double-double.

Leo
Time: 10:28 PM CDT
Instrument: Visual + Binoculars 
S&T Chart Reference: 34, 35

First noticed Regulus very low in the sky, about 5º above the horizon with Venus nearby. Could faintly make out Denebola and may have seen θ Leonis and δ Leonis, but not sure. Definitely didn't see his legs or most of his mane/head.

Lyra
Time: 10:28 PM CDT
Instrument: Visual + Binoculars 
S&T Chart Reference: 63
Easily located Vega. Used my binoculars to locate ε1 and ε2, ζ, δ1 and δ2 Lyrae. Didn't/Couldn't see the double stars of the double stars in ε.

M8 (Lagoon Nebula)
Time: 10:55 PM CDT
Instrument: Binoculars 
 
S&T Chart Reference: 67, 69, I
Found the Teapot then used its spout to locate M8. The line of 5 bright stars with the surrounding oval-shaped nebulosity was easily identified as M8. The lanes of the Milky Way were now becoming evident.

Ophiuchus
Time: 10:56 PM CDT
Instrument: Visual  
S&T Chart Reference: 54, 56, 67

The curved line of stars above Scorpius caught my eye. Very quickly located α, β and κ at the top of the huge figure, but only visually. Didn't look for the accompanying stars in Serpens Cauda and Serpens Caput.

Cassiopeia
Time: 10:56 PM CDT
Instrument: Visual + Binoculars 
S&T Chart Reference: 1, 3, 72
Easily located all 5 stars of this constellation in the NE sky.

Cygnus + Coathanger / Collinder 399 / Brocchi's Cluster 
Time: 10:58 PM CDT
Instrument: Visual + Binoculars 
S&T Chart Reference: 62, 73, H
Easily located Deneb visually, then located Sadr, Albireo, ε and λ.

Used the binoculars to view the double in Albireo. Could see the larger yellowish star β1 and the bluish companion albeit smaller β2. Also used Albireo to locate all 10 stars of the Coathanger.

Within 10 minutes, the light and dark lanes of the Milky Way became visible.

   

Meteor
Time: 11:12 PM CDT
Instrument: Visual + Binoculars 
There was a very bright flash near Cygnus. It then moved left to right in my binocular FOV before disappearing.

Regulus could not be seen as a separate entity but it did make Venus appear misshapen at its SE limb. At 10:40 PM, Regulus couldn't be seen at all. I used the binoculars to view the occultation and also identified the star 31 Leo below Regulus. I did not see Regulus appear on the NW limb later in the evening.

Transparency: Very Good (4)
Seeing: Very Good (4)
Temperature: 11º C - 8º C
SQM: 13.59 - 20.59
Very little if any breeze. Dry air so seeing and transparency were fairly good. Only a few clouds on the horizon towards the Rocky Mountains.

We were camped on an open flat field that was adjacent to the fenced-in buffalo pen/range and close to the historic site.

Constellation: Aquila, Cygnus, Lyra, Perseus
Asterism: Summer Triangle

Planet: 
Jupiter, Venus (in Leo)
Open Cluster: Alpha Persei Cluster
Noctilucent Clouds

Jupiter (in Libra)
Time: 10:55 PM MDT
Instrument: Visual + Binoculars 
Thought I saw all 4 moons but in reality only saw three. Jupiter was at 2 o'clock to Zubenelgenubi (α1 and α2). What I thought was a planet was later identified (believe it or not) as TYC 577-0952-1.

Venus (in Leo)
Time: 10:55 PM MDT
Instrument: Visual only
Venus was 10º above the horizon with approximately a 10º separation from Regulus.

   

Cygnus
Time: 11:16 PM MDT
Instrument: Visual only
S&T Chart Reference: 62, 73, H
Deneb and Glenah were very clearly seen, as were some of the stars in the wings.

Aquila
Time: 11:16 PM MDT
Instrument: Visual only
S&T Chart Reference: 64, 65, 66
Aquila was easily identified as Altair could easily be located. Due to the brightness of the sky at this hour of night at approximately 52º N altitude, not all the stars could be seen for this constellation.

Summer Triangle (DAVe)
Time: 11:20 PM MDT
Instrument: Visual only
Used binoculars to look at Vega and its adjacent Lyrae stars. Visually located Deneb and Altair.

Lyra
Time: 11:16 PM MDT
Instrument: Visual only
S&T Chart Reference: 63
Used my binoculars after locating Vega to see the double-double at epsilon Lyrae. I certainly saw the double stars but did not see their double. Also saw δ1, δ2, and ζ Lyrae. Did not look for Sulafat (γ Lyrae) nor Sheliak (β Lyrae).

Perseus + Alpha Persei Cluster
Time: 12:40 AM MDT
Instrument: Visual only
S&T Chart Reference: 2, 13
Visually saw the stars in Perseus towards the north. Used my binoculars to identify Mirfak and its glorious open cluster, Alpha Persei Cluster.

Noctilucent Clouds (NLC)
Time: 2:21 AM MDT
Instrument: Visual 
The sun had already set in the west and the remnants of light indicating its last attempts to illuminate our sky was barely evident.

However, 20º - 25º to the NW were clouds that were very well illuminated - and it wasn't the sunset! Turns out it was noctilucent clouds. These electric blue clouds also called "polar mesospheric clouds". Ice crystals at about 80 - 85 km above Earth reflect the Sun's light during a period of time from about 90 minutes to about 2 hours after sunset or before sunrise. This occurs at latitudes 50º - 70º north and south. We were at 52.3488º N. The clouds are visible only when they are illuminated by sunlight below the horizon while the lower layers of the atmosphere are in Earth's shadow.

A beautiful sight. A moving experience in the badlands of Alberta.

M31 / Andromeda Galaxy + Cassiopeia
Time: 11:32 PM MDT
Instrument: Visual
I used Cassiopeia's Navy-Shedar-Caph "arrow" to find the two lines of stars that are part of Andromeda. It was then easy to locate the faint oval fuzzy in the night sky. The centre did appear brighter than the exterior portions of the oval. The trees hid the Square of Pegasus that I usually use to locate M31.

Saturn (in Sagittarius)
Time: 12:04 AM MDT
Instrument: Visual
Saturn appeared to be about 7º away from Kaus Borealis, located at approximately 2:30 o'clock from the star. Did not use my binoculars to visualize the rings.

Relatively clear with just a light breeze. We had had a big thunderstorm when we were setting up camp. Felt like Dorothy in the Wizard of Oz, just waiting for the wind to lift us inner tent up into the storm.  The early evening was cloudy but it did clear for some viewing. Because of the size of the Moon, it negated any chance of viewing the star field this evening.

A little hazy (especially on the horizon), no wind. Waxing Gibbous Moon (90.6%) on the rise. Some time was spent with binoculars identifying lunar features (Lunar Session - June 24, 2018) as part of the RASC Explore the Moon (Binocular) program.

Jupiter (in Libra)
Time: 9:47 PM CDT
Equipment: Visual + Binoculars 
S&T Chart Reference: 46, 57

Jupiter was within 10º - 15º from α1 Libra and α2 Libra (visually). With binoculars, one could see the Galilean moons - 2 on each side.

C: Callisto
I: Io
E: Europa

Conjunction (Mercury-Castor-Pollux) + Venus
Time: 10:04 PM CDT
Equipment: Visual

The Moon was beginning to rise in the East and obliterating chances of seeing stars in the East and South. Looking westward, I located Mercury 5º above the horizon and within 10º of Castor & Pollux.

Venus was nearby and only 15º above the Grasslands horizon and at 10 o'clock from Mercury. Although a bit bleached out by the Moon, these were easily located and identified.

No wind or clouds. Less humidity than Agawa Bay the night before. Also read about the other observations made this evening in General Session - June 20/21, 2018.

There was a bump that created a shadow. Looked like a high peak on the side of a crater - maybe the crater below Curtius (?). Also identified Palus Putriedinus.

The Moon was also situated in Virgo.

The Moon had changed its location within Virgo compared to the night before.

Equipment: Visual + Binoculars, 10x42 IS
Transparency: Good (3)
Seeing: Good (3)
Temperature: 19º C
SQM: 19.89
No wind or clouds but felt there was more humidity here than the night before in Agawa Bay. Also, smoke in the atmosphere may also be limiting seeing and transparency. To add to the wonder of the night was the baleful loon calls across the lake around midnight. Some of the evening was spent observing the moon; read all about it in Lunar Session - June 20, 2018.

Venus (in Cancer)
Time: 10:35 PM EDT
Equipment: Visual + Binoculars 
S&T Chart Reference: 24
The stars of Cancer couldn't be seen that well so used SkySafariPro to determine the constellation was Cancer. Venus was so close to Asellus Borealis (γ) and Asellus Australis (δ) that the stars couldn't be seen. Even with binoculars, ι and Acumen's (α) were a challenge and β wasn't visible at all. 
   

Jupiter (in Libra)
Time: 10:35 PM + 11:55 PM EDT
Equipment: Visual + Binoculars 
S&T Chart Reference: 46, 57

Observation #1 @ 10:35 PM:
Jupiter was shining bright and easily located visually. We were on the edge of smoke in the atmosphere but not quite sure if we truly had smoke. Stars were not seen as early as they were the night before. The planet was similar to last evening's location.

Observation #2 @ 11:55 PM:
Only see 3 Galilean moons could be seen.
Io was so close it just made Jupiter look misshapen. Could not see Europa at all.

   
Scorpius
Time: 11:30 PM EDT
Equipment: Visual + Binoculars 
S&T Chart Reference: 56, 58, J
Scorpius was slowly rising with Antares making its presence known. Took my binoculars to see what I could see near Graffias and Dschubba. Saw a pair of stars close to Graffias. Later identified them as ω1 and ω2. Something new to me!
   

Cygnus + Coathanger/Brocchi's Cluster/Collinder 399
Time: 11:37 PM EDT
Equipment: Visual + Binoculars 
S&T Chart Reference: 62, 73, H
Cygnus rose behind us above the trees of our campsite. As was the case the night before, Deneb was noticed first, then came the wings and followed down to the double star Albireo. Used my binoculars and saw the Coathanger once gain in the same FOV. All 6 of the "hanger" were seen but only 3 of the 4 "hook".

Ophiuchus
Time: 12:13 PM EDT
Equipment: Visual 
S&T Chart Reference: 54, 56, 67
I noticed the sweeping curve of the bottom of Ophiuchus from Nehushtan to Yed Prior. Looked higher in the sky to locate Rasalhague, then located and identified the other major stars in the constellation.

   

Serpens Caput
Time: 12:13 PM EDT
Equipment: Visual 
S&T Chart Reference: 55
After identifying Ophiuchus, I noticed a snake-like line of stars - Serpens Caput. Very pleased with self that I located all the stars visually. Didn't use the binoculars to view the double stars in δ and β.

   

Serpens Cauda
Time: 12:13 PM EDT
Equipment: Visual 
S&T Chart Reference: 65,67
After identifying Ophiuchus, I noticed the other half of the snake-like line of stars - Serpens Cauda. Very pleased I could see θ, 4,  η and τ as they led to ν Ophiuchus. Didn't use binoculars to view the double stars of θ and τ.

NOTE: Had seen Serpens Cauda in the Atacama Desert, Chile, but did not document it.

Equipment: Visual + Binoculars 10x42 IS
Transparency: Very Good (4)
Seeing: Very Good (4)
Temperature: 12º C
SQM: 21.66

No wind. Clouds only in the W-SW.

At 10:40 PM EDT, the Moon was due south above the horizon in Virgo. With my binoculars, I removed the Moon from my FOV and saw a faint star that I later identified as ν Virgo. beta Virgo (Zavijava) could easily be seen at 7 o'clock to the Moon.

Mare: Crisium, Frigoris, Tranquilitatis and Serenitatis, and Sinus Asperitatis.

Montes: The Montes Caucasus disappeared into the terminator.

Craters: Albategnius, Aliacensis, Aristillus, Aristoteles, Blanchinus, Eudoxus, Hipparchus, Plinius (no shadows), Werner. The Gang of 4 showed as completely white.

At 1:35 AM EDT, the Moon was disappearing into Lake Superior. It was an orangish-gold and what was really cool was how the bands of cloud sliced the Moon and made it appear misshapen. Its a beautiful thing - the Moon going down and its perfect reflection across the glass-like surface of the Lake.

Ursa Major
Time: 10:52 PM EDT
Equipment: Visual + Binoculars 
S&T Chart Reference: 31, 32, 33, 43, F
Visually located the "Big Dipper" asterism then used my binoculars to view Mizar-Alcor. Also used the pointer stars to locate Polaris.

Jupiter (in Libra)
Time: 10:40 PM - 11:06 PM + 2:30 AM EDT
Equipment: Visual + Binoculars 
Jupiter was very bright and seen visually. Binoculars provided the view of alpha1 Librae and alpha2 Librae approximately 3º away.

At 11:06 PM, all 4 moons of Jupiter could be seen. However, I had to place the eyepiece so that the FOV didn't include the planet in order to see the moon closest to it - Io.

At 2:30 AM, Jupiter had a beautiful reflection on Lake Superior.

   

Lyra
Time: 10:57 PM EDT
Equipment: Binoculars
S&T Chart Reference: 65
Flies had disappeared. Vega was very high above the trees. Used my binoculars to identify the double stars of ε Vega and δ Vega. Sulafat was hidden by one of the tall trees.

Summer Triangle / DAVe
Time: 11:00 PM EDT
Equipment: Visual
Easily located and identified Vega, Deneb, and Altair.

Cygnus + Coathanger / Brocchi's Cluster / Collinder 399
Time: 11:21 PM EDT
Equipment: Binoculars
S&T Chart Reference: 65
Identified Cygnus. Just as I located and identified Deneb, a lone loon called out across the water. Such a beautiful yet haunting sound.

I followed the constellation's stars down to Albireo with binoculars. Albireo's two components were easily viewed. Looked for the Coathanger and saw it and Albireo in the same FOV! How cool is that!

Satellite
Time: 11:39 PM EDT
Equipment: Binoculars
Noticed the satellite just west of Deneb. Followed it below Cygnus along the light lane of the Milky Way. Lost sight of it in the trees.

Scorpius
Time: 11:42 PM + 1:35 AM EDT
Equipment: Visual
S&T Chart Reference: 56, 58, J

11:42 PM
Antares was twinkling red and white-yellow. Couldn't see Scorpius' tail as it was partially below the horizon and partially hidden by the trees.

1:35 AM
All of Scorpius was now above the horizon. Could visually identify all the major stars within the constellation - the full length from δ through the curve of the tail to Shaula and Lesath.

 
Sketched at 11:42 PM

Mars (in Capricornus)
Time: 2:18 AM EDT
Equipment: Visual
S&T Chart Reference: 64
Mars was finally high enough in the SE sky to see it. Didn't initially realize it was in Capricornus. If you drew a line from 24 Cap to Dabih Major, Mars was next to that line 1/3 of the way up from 24 Cap.

   

Delphinus
Time: 2:18 AM EDT
Equipment: Visual
S&T Chart Reference: 64
Saw the constellation visually very easily. All 5 stars could be located and identified.

Equuleus
Time: 2:20 AM EDT
Equipment: Visual
S&T Chart Reference: 75
Accidentally. found Equuleus while viewing Delphinus. Visually could see γ, δ, α and ε. Could also see β but did't realize at this time that it was part of the constellation.

Saturn + the Teapot (Asterism in Sagittarius)
Time: 2:26 AM EDT
Equipment: Visual
S&T Chart Reference: 66, 67, 68, 69, I
The Teapot was at least 3º above the horizon earlier in the evening. All 8 stars were readily identified visually.

At this hour of the morning, the Teapot was was 5º above the horizon with Saturn directly above Kaus Borealis - just like in the Atacama! I didn't use my binoculars to view the rings.

Satellite
Time: 2:26 AM EDT
Equipment: Binoculars
Trying to locate δ Cephei. Followed the satellite from there through Camelopardalis to Lynx. About 15 seconds before it disappeared, it became very bright for a second or two.

SQM: 25.8 - 27.8 (not possible, but that was the reading)

The clouds disappeared, wind dropped, lots of black flies and mosquitos in the early evening. Amazing sky! With no manmade lights, the stars created our shadows and those of the picnic table and camera gear on the beach. Never had this happen before! A very definite "OH WOW"moment!

Scorpius
Time: 10:10 PM ADT
Equipment: Visual
S&T Chart Reference: 56, 58, J
Antares was the second bright object identified this evening (after Jupiter). Visually, it was twinkling two colours - red and a gold-white. The red stood out for the majority of the time. Eventually, Graffias, δ, π, ρ and ν became visible and eventually could also see τ and ε rise above the mountain ridge.

Satellite
Time: 10:10 PM ADT
Instrument: Binoculars
Was looking through binoculars at Antares when the satellite entered my FOV. I followed it from Scorpius across the sky to Sadr in Cygnus where I lost sight of it. Never have I been able to follow a satellite for such a long distance across the skies.

 Aquila
Time: not recorded
Equipment: Visual
S&T Chart Reference: 64, 65, 66
First identified the star Altair and its adjacent stars Tarazed (γ) and Alshain (β). Could identify the stars in its wings to the tips and all the way down to λ. It was amazingly clear. The light and dark lanes of the Milky Way were phenomenal!!

Boötes
Time: not recorded
Equipment: Visual
S&T Chart Reference: 42, 44, 53, 55
Arcturus was very bright in the early evening sky. It wasn't until much later the other stars of the "kite" could be located and identified, except λ, θ and κ.

Ursa Major
Time: 10:52 PM ADT
Equipment: Visual
S&T Chart Reference: 31, 32, 33, 43, F
Didn't look for this constellation initially as it was behind us above the trees and we were looking at the mountains opposite it. It wasn't until we were trying to follow this incredible Milky Way that we saw it. Identified the Big Dipper asterism but none of the other stars. Used the pointer stars to locate Polaris in Ursa Minor.

Cygnus
Time: 11:10 PM ADT
Equipment: Visual + Binoculars 
S&T Chart Reference: 62, 73, H
Once identified as Cygnus, I could see 2 stars in each direction from Sadr, then all the way down to Albireo. Looked at Albireo with binoculars and could see the double blue and gold-yellow stars very clearly. East to find the Coathanger from there.

Cassiopeia
Time: 11:15 PM ADT
Equipment: Visual 
S&T Chart Reference: 1, 3, 72
All the stars of Cassiopeia could be seen and identified. However, the constellation was not high enough in the sky at this time to locate M31 nor Kemble's Cascade.

Satellite
Time: 11:25 PM ADT
Instrument: Binoculars
Looking at Corona Borealis when the satellite entered my FOV. It was followed to δ Cygni before disappearing.

Lyra
Time: 11:32 PM ADT
Equipment: Visual + Binoculars
S&T Chart Reference: 63
Vega easily located and seen visually. Used my binoculars to observe the 3 sets of double stars - ε, ζ and δ. Didn't look for ν1 or ν2. 

Delphinus
Time: 11:48 PM ADT
Equipment: Visual + Binoculars
S&T Chart Reference: 64
Was looking at Cygnus when Delphinus caught my eye. Not very bright this evening but did see all 5 stars of the constellation.

Coathanger / Collinder 399 / Brocchi's Cluster
Time: 11:35 PM ADT
Equipment: Visual + Binoculars
S&T Chart Reference: 65
Found Albireo in Cygnus, then easily found the Coathanger. HD182293 wasn't seen but the other 5 of the hanger and all 4 of the hook easily seen. And, yes, it was upside-down again and tilted at about 40º - 45º.

Satellite
Time: 11:35 PM ADT
Instrument: Visual
Looking at the Keystone of Hercules to determine if I could see M13. Satellite appeared, travelling from eta Hercules to zeta Hercules (parallel to this line) before disappearing in Draco.

Summer Triangle / DAVe
Time: 12:05 AM ADT
Equipment: Visual
Could easily see all three stars of the DAVe asterism - Deneb (in Cygnus), Altair (in Aquila), and Vega (in Lyra).

Corvus
Time: 12:05 AM ADT
Equipment: Visual
Just happened to look over to the lake's far shore and saw Corvus above the low-lying hills. Crater had already gone below the horizon. Could see all 5 of the main stars; just a little faint but still could be easily seen.

Jupiter (in Libra)
Time: 12:02 AM ADT
Equipment: Visual + Binoculars
S&T Chart Reference: 46, 57
Jupiter was the first object we could see in the early night sky. β Librae was almost directly above α Librae.

Using binoculars, was able to see α1 Librae and α2 Librae that were adjacent to Jupiter.

Used the binoculars on the side deck after seeing Jupiter through our bedroom window. I wanted to determine where Jupiter was in relation to the α Librae-β Librae line. Jupiter was now above it but more importantly was once again seeing the double star at α Librae. Was also able to see two other bright stars with the binoculars that I later determined were 5 Librae and μ Librae. 

α1 - larger of the two in the double, brighter and yellowish
α2 - much smaller, almost pinpoint. Couldn't determine a colour.

Jupiter
Could make out all 4 moons of the planet but had to use slight averted vision to distinguish between Io and Europa due to the brightness of Jupiter.

General Session - May 30, 2018

Constellations: Cepheus
Double Stars: δ Cephei & HD 213307
Moon: Waning Gibbous (97.9%)

Location: Home
Date: 2018-05-30
Time: 2:15 AM ADT
Equipment: Visual + Binoculars, 15x70 + 10" Meade SCT with 30 mm eyepiece
Transparency: not recorded
Seeing: not recorded
Temperature: 7º C
Light breeze, no clouds.

SUCCESS! Despite the almost full Moon, I located Cepheus above our roofline. 

Visually: was able to locate δ Cephei.

Binoculars: Used the binoculars on a tripod and located δ, ε and ζ Cephei but could not positively identify the companion star.

Telescope: I used the 10" Meade SCT to navigate to Cepheus then manoeuvred to δ Cephei, and there was the companion star HD213307. δ Cephei was bright yellow and almost double in size compared to its blue-yellow companion.

There was a row of 3 stars below them and then discovered the centre star (H4) was also a double (using averted vision). All the other stars in the FOV were fairly faint. More time required at the eyepiece.

Woke up to the Moon shining in the bedroom window, Jupiter not far from it. I again watched the Moon between the clouds in the partly cloudy skies - both visually and with binoculars. Jupiter was relatively close as well. 

In a large sucker hole was α Libra (Zubenelgenubi) and β Libra (Zubeneschamali), but Brachium was in the cloud cover below. Jupiter had certainly moved closer to α and was almost sitting centred on the α-β Librae line.

1- @9:27 PM: Had to view the Moon and Leo between the clouds. Could easily identify tiny Regulus and 31 Leo in close proximity. Regulus was just tot he south of the Moon's south limb terminator; the terminator was parallel t the line formed by Regulus and 31 Leo.

2- @10:30 PM: Still catching between cloud cover intervals. Moon had moved a bit SE of its previous position. Besides Regulus and 31 Leo, ν Leo was now faint but seen with the binoculars. The Moon looked to be sitting at the intersection of Regulus-η Leo and 37 Leo-ν Leo.

3- @ 11:28 PM: The Moon had again moved SE of its previous position.

4- @ 1:28 AM: The Moon had moved to a position east of Regulus and looked to be nearing the intersection of Regulus-θ Leo and 37 Leo-31 Leo. At this point, it was very low in the sky, about 10º - 12º above our backyard horizon.

5- @ 2:05 AM - 2:20 AM: The Moon again had moved a bit SE from its previous position and was now below θ Leo-Regulus line. It was also a few degrees from the horizon. at 2:20 AM, it disappeared from our view. Interesting to watch the glow in the sky disappear at the horizon s the Moon set.

High winds at the start of the session earlier in the evening that disappeared in the early morning. No clouds.

Conjunction - Moon-Regulus (in Leo)

This was my second night to observe the motion of the Moon as it travelled through Leo.

Observation 1: at 9:27 PM:
Moon: 48.5%
Had to view the moon and Leo between the clouds. Could readily identify Regulus and 31 Leo in close proximity. Regulus was just south of the Moon's south limb terminator; the terminator was parallel the line formed by 31 Leo and Regulus.

Observation 2: at 9:27 PM:
Moon: 48.5%
Still catching it between cloud cover intervals. Moon had moved a bit SE of its previous position. Besides Regulus and 31 Leo, ν Leo was now faint but seen with the binoculars. The Moon looked to be sitting on the intersection of Regulus-η Leo and 37 Leo-ν Leo.

Observation 3 at 11:28 PM:
Moon: 49.5%
The Moon had again moved SE of its previous position.

Observation 4 at 1:28 AM:
Moon: 50.4%
The Moon had moved to a position east of Regulus and looked to be sitting near the intersection of Regulus-θ Leo and 37 Leo-31 Leo. At this point, it was very low in the sky, about 10º-12º above our backyard horizon.

Observation 5 at 2:05 - 2:20 AM:
Moon: 50.7%
The Moon had again moved a bit SE from its previous position and was now below the Regulus-θ Leo line. It was also a few degrees from the horizon. At 2:20 AM, it disappeared from our view. Interesting to watch the glow in the sky disappear at the horizon as the Moon set.

   
   
  

Jupiter (in Libra)
Time: 11:06 PM ADT
Instrument: Visual + Binoculars + 10" Meade SCT
Jupiter was evident throughout the observing session as it travelled southerly.

Visually: It was close to the α Librae-β Librae line.

Binoculars: The moons were not aligned but rather formed a saucer beside the planet. Could not see the bands on the planet.

Telescope: Bands were almost vertical (relative to our horizon). The Giant Red Storm (GRS) again was not seen. The saucer of the moons supported the planet and were left-right reversed to my binocular view.

   

Satellite
Time: 11:17 PM ADT
Instrument: Binoculars
Was looking at Messier 101 beside Alkaid and Alcor-Mizar when a satellite came through my FOV travelling parallel to the line formed by by the 3 stars. It disappeared just as it passed Alkaid.

   

Cepheus
Time: not recorded
Instrument: Binoculars
S&T Chart Reference: 71, 73
I tried to locate Cepheus several times over a 5-hour period. I could see a 5-star formation in binoculars. Visually, I could see δ Cephei, ε Cephei, and ζ Cephei - ε was harder to see but I could see it.

The double star could be seen (as circled in the sketch) but not sure if the pair was in fact δ Cephei or if the brighter star (not seen as a double) was the double. Will need to attempt to see this with a telescope at some time.

General Session - May 18, 2018

Constellation: Auriga, Cepheus
Conjunction: Moon-Venus (Refer to Lunar Session - May 18, 2018)
Messier Objects: M36 (Pinwheel Cluster), M37 (NGC 2099), M38 (Starfish Cluster)
Stars:
Mekbuda in Gemini
Planets:
 Jupiter (in Libra)

Location: Home
Date: 2018-05-18
Time: 8:30 PM - 11:00 PM ADT
Instrument: Visual + Binocular 10x30 IS + 10" Meade SCT with 30 mm eyepiece
Transparency: Good (3)
Seeing: Good (3)
Temperature: 9º C - 3º C

Clear skies, no cloud, no wind. Hazy near the horizon. Part of this session was for lunar observing, especially with the conjunction of the Moon with Venus and Mekbuda (in Gemini). 

Auriga & 3 Messier Objects ( M36, M37, M38)
Time: 9:37 PM - 10:35 PM ADT
Equipment: Visual + Binoculars + Telescope
S&T Ref Chart: 12, 23, 14, (25)
I could make out all the stars of Auriga and knew that 3 of the Messier Catalogue objects were in the constellation and were basically in a line from west to north but not in numerical order.

M37 / NGC 2099 @ 10:00 PM
Now that I know M37 is an open cluster (not a globular), I had a better chance of finding it. Using my binoculars, I discovered it was very loose! There was a brighter central star with 5 other bright st are. The haziness near the horizon made for difficulty in finding more stars of the cluster. After a few tries at it, I drew the cluster as I saw it. Jerry then used the go-to on our 10" Meade SCT to confirm this was indeed what I was looking at.

M36 / Pinwheel Cluster @ 10:20 PM
Having found M37 20 minutes ago, it took almost all of that time to locate it then sketch it. I first located a grey fuzzy to the north of M37 in my binoculars. Due to the haziness of the sky that close to the horizon, I couldn't make out any one star that was bright. However, in slewing the telescope from M37 to M36, I was able to detect 10 bright stars. The remaining star field was diffuse.

M38 / Starfish Cluster @ 10:28 PM
I knew M38 was the furthest north. Having found M36, I moved my binoculars just a little to the north (~ 1 FOV). It was very faint in binoculars so tired to locate it with the telescope. I slewed the scope from M36 to M38 and found it! Still a bit faint and very diffuse in the eyepiece; only 4 definitive stars were seen. The rest of the star field was diffuse enough, perhaps because of haziness closer to the horizon, that the "cross structure" I had read about wasn't truly visible.

Auriga
M37 / NGC 2066
M36 / Pinwheel Cluster /
NGC 1960
M38 / Starfish Cluster

Jupiter (in Libra)
Time: 10:43 PM ADT
Equipment: Visual + Binoculars + Telescope

Visual: Jupiter was getting closer to the α-β line of Libra.

Binoculars & Telescope: Easily found the planet and saw its 4 Galilean moons.

Telescope: Could make out the bands but not the giant red storm (GRS) on the planet. The bands were almost perpendicular to the visual horizon.

   
Jupiter and its Galilean moons (in Libra)

Cepheus
Time: 11:17 PM ADT
Equipment: Visual + Binoculars
S&T Ref Chart: 71, 73
All 8 main stars of the constellation could be found in the northern sky above our neighbour's trees. My target for tonight was δ Cephei. After blocking out their street light, I located the area of δ Cephei visually and then with the binoculars. I found the variable Cepheid but could not make out the 2 stars of the double, just a single bright star. Will need to go out again and confirm this find with binoculars and then with the telescope.

Identified, Not Observed: Arcturus, Castor, Cassiopeia, Pollux, Spica

Not found: M47 - My attempts to find this object were thwarted by the tree line on the S-SW area of our property. Sirius could be seen but it was very low on the horizon.

Location: Home
Date: 2018-05-14/15
Time: 9:00 PM - 1:30 AM ADT
Instrument: Visual + Binoculars 10x42 IS + 10" Meade SCT with 10 mm Speers-Waler
Transparency: Fair (2) - Poor (1)
Seeing: Fair (2) - Poor (1)
Temperature: 13º C - 8º C

Jerry and I were in the back yard - me observing and him astroimaging. No wind or clouds bu there're may have been a very light haze. Dew is settling on surfaces. Visibility and transparency were not as good as a couple of nights ago.

Venus
Time: 9:08 PM ADT
Equipment: Visual + Binoculars

Venus was very bright in the SW sky at about 25º to 30º above the horizon. It has changed position from the previous night's location. It has moved quite a bit from the Ain-Elnath line to being between ζ Tau and Elnath. Also tried using the Venus-Capella line to locate M37. Failed.

 

 

M37 / NGC 2099
Time: 9:37 PM ADT
Equipment: Visual + Binoculars
S&T Chart Reference: 12

Could make out all of Auriga's stars and I knew that M37 was west of the line formed by theta Aur and beta Aur. Could not see it visually.

Using binoculars, I put Venus at 7 o'clock in my FOV which put the top of the neighbour's clothesline at the top of the FOV. I went almost straight up from there but couldn't see the open cluster. Will try earlier in the evening next time when Auriga isn't setting and, when higher, will make star-hopping a lot easier - especially if observing conditions improve.

Jupiter
Time: 11:47 PM ADT
Equipment: Visual + Binoculars + Telescope

Libra was almost on her side in the southeast sky. Jupiter was located very close to the line between α and β Librae as compared to May 8/9, 2018. I used binoculars to see the moons - only saw 3 (Callisto, Europa and Ganymede). I guessed that Jupiter was bright enough to hide Io, the one closest. Then Jerry set up the telescope to look at Jupiter. This confirmed my binocular view but also provided a view of Io.

   

Ceres (Minor Planet)
Time: 11:12 PM ADT
Equipment: Visual + Binoculars
Tonight I was determined to find Ceres with binoculars - and was successful!

I used ε Leonis and μ Leonis to locate κ Leonis. Cancer took some staring for a few minutes so did find ι and Asellus Borealis. Using an imaginary line between ε Leonis and ι Cancer, I confirmed κ Leonis. Ceres, when centred in my FOV, was at 5 o'clock to κ Leonis but wasn't as bright. Averted vision was sometimes required to see Ceres. It had helped to study the star charts in advance of this search!

   

 

Boötes
Time: 12:03 AM ADT

Equipment: Visual + Binoculars
S&T Chart Reference: 42, 44, 53, 55

Arcturus was located high above Venus. I took my time to find all the stars of the constellation because of the less than great seeing and transparency. The part I couldn't locate was the 'arm' from Seginus to what I call the  'Asellis Triangle' - Asellus Primus, Asellus Secundus and Asellus Tertius.
Lyra
Time: 12:05 AM ADT
Equipment: Binoculars
S&T Chart Reference: 63
Saw Vega high in the E-SE sky and could faintly make out some of the stars in constellation. Used my binoculars to find two sets of double stars - ε Lyrae and δ Lyra. Success!
   

   

   

Scorpius
Time: 12:12 AM ADT
Equipment: Binoculars
S&T Chart Reference: 56, 58, J
Noticed Antares and some of the stars southeast of it. Because it was so low on the horizon, (~ 15º to 20º), the Halifax-Bedcford light pollution obliterated the lower stars that could have potentially been seem. 

On going through my scratch notes, I realized I had also seen ω1 and ω2 that were very bright adjacent to Graffias.

   
Cygnus
Time: 12:20 AM ADT

Equipment: Visual + Binoculars
S&T Chart Reference: 62, 73, H

While looking at Hercules about 20 minutes earlier, I noticed Deneb but ignored it for the time being. Being determined, I located the swan's stars despite the sky conditions. Certainly her wings took a bit of effort and not quite sure if I actually saw ι2 and ζ or just imagined them. Seeing Albireo, I easily located the Coathanger.

Coathanger / Collinder 399 / Brocchi's Cluster
Time: 12:26 AM ADT

Equipment: Visual + Binoculars
S&T Chart Reference: 65

Located Albireo a few minutes earlier so decided to find the Coathanger. Albireo was used to locate the asterism at about 4:30 o'clock from the star. It was upside-down  once more as compared to our recent experience in Chile, and was at a 45º angle. I decided to label all of the stars in Collinder 399.

   

Hercules & M13
Time: 12:33 AM ADT
Equipment: Visual + Binoculars
S&T Chart Reference: 71, 73
Saw the Keystone of Hercules adjacent to Vega very high in the E-NE sky, the stars barely visible. Took about 5 minutes to locate the star arms to Kornephoros and γ Hercules and to Sarin and Rasalgetti. Couldn't locate the stars in the other two arms.

I found M13 easily enough in the same FOV of my binoculars as eta Herculis. It was circular with no clearly defined or bright stars evident.

     
   
   

Ophiuchus
Time: 12:55 AM ADT
Equipment: Visual
S&T Chart Reference: 54, 56, 67
Having located Hercules, I noticed a bright star relatively close to Rasalghethi. Turns out it was Rasalhague (α Oph). Because it was relatively high in the sky, I was able to visually locate the main stars that outline the constellation. It took at least 5 minutes due to poor seeing and transparency at the time and he was lying on his side per se. I didn't look for Serpens Cauda nor Serpens Caput. Couldn't see θ Oph nor 45 Oph.

Cepheus
Time: 12:57 AM ADT + 4:30 AM ADT
Equipment: Visual + Binoculars
S&T Chart Reference: 71, 73
Had to wait for Cassiopeia and Cepheus to rise above the neighbour's house and trees and away from the street lamp.

12:57 AM:
δ Cepheus didn't appear as a double star in my binoculars, probably due to the poor sky conditions. However, I could locate all the major 8 stars of Cepheus visually then used my binoculars when δ Cepheus could be seen. There was a visual row of 3 stars in the binoculars that were later identified (refer to sketch).

4:30 AM:
Got up early to see off δ Cepheus was visible. Between the very hazy condition and the sun rising, I could only visually see Aldermin (α Cepheus). I tried using my binoculars to guesstimate its location but didn't succeed.

We were driving home from SCO when a red object appeared on the horizon before us - Mars. It was a definite red in appearance so no question as to its identity. In lined with it were 2 more planets - Saturn and Jupiter. Couldn't see what constellations they were in due to the internal reflections of the car's windshield and lights of oncoming traffic. Mars was approximately 5º above the horizon.

Saw this 3 nights ago at SCO through Bruce Hamilton's telescope. Used two stars in UMa (Dubhe 7, 23 UMa) to locate M82. Earlier tonight, I located the elongated shape in my 10x42 IS binoculars.

Used the line between these 2 stars then went 'up' just past the halfway point towards 23 UMa. The telescope provided a much grander view of this galaxy. A bright nebulous oblong object, particularly bright in the centre. It almost appeared as if the bright centre cut the cigar in half.

Searching through the night skies with our SCT. Looked specifically for Coma Berenices then pushed to α Com and M53 just up from it at about 11 o'clock.

It is fairly bright and condensed, but a few bright stars were seen with averted vision. These stars seemed to provide a bright centre as opposed to the consistent brightness across the globular cluster.

Instrument: Visual + Binoculars 10x42 IS + 10" Meade SCT with 30 mm Speers-Waler eyepiece
Transparency: Very Good (5)
Seeing: Very Good (5)
Temperature: 13º C - 9º C

Jerry and I were the only 2 at SCO this evening. The wind made it feel colder than was. There were ripples on the pond in front of the observatory and on the river. No clouds. No flies! First time using my Sky Quality Meter (SQM)!

Venus (in Taurus)
Time: 9:08 PM ADT
Instrument: Visual
Went out to the road to get away from the trees. Venus appeared to have moved to the left of the line between Elnath and Ain and also lower in the sky, or so it seemed. While looking for ζ Tau, I came across a very red star - Betelgeuse!

Jupiter (in Libra)
Time: 9:15 PM + 12:15 AM ADT
Instrument: Visual + Binoculars
Jupiter was in opposition.
Visual: @ 9:15 PM - Saw Jupiter half way up the trees but could not make out Libra.
Binoculars: @ 12:15 AM - Tried earlier to see Libra earlier in the evening but haze prevented it. Finally saw α, β and σ with Jupiter somewhere in the line between α and β and not just towards α.

Winter Circle
Time: 9:18 PM ADT
Instrument: Visual
Had gone out to the road to locate Aldebaran and Tau θ1 and θ2 - not! Too low in the sky. However, I did see other stars of the Winter Circle that is slowly sinking below the horizon in the west - Procyon, Pollux, Castor, and Capella.

A happy coincidence was that while searching visually and with binoculars, I saw a bright red star at the same level as ζ Tau but much further south - Betelgeuse!

 

Cancer, M44/Beehive Cluster/Praesepe, & M67
Time: 9:18 PM ADT
Instrument: Visual + Binoculars + Telescope
S&T Chart Reference: 65

Caught this constellation next to Leo and above Hydra. All the stars were very faint so it took a while to locate them.

I actually found M44 while searching in that area for α Serpens. Noticed it visually then used the binoculars. After that, I took some time to locate the faint stars of this constellation, i.e., faint relative to other stars adjacent to it. While doing so, I also found M67.  I viewed the two Messier Objects visually, with my binoculars and then Jerry located them with our 10" Meade SCT.

M44 / Beehive Cluster / Praesepe
Time: 10:10 PM ADT
Instrument: Visual + Binoculars 
S&T Chart Reference: 24
Refer to the entry for this in  For details, refer to Messier Catalogue - M044 (Beehive Cluster / Praesepe) - May 8/9, 2018

M67
Time: 10:10 PM ADT
Instrument: Visual + Binoculars 
S&T Chart Reference: 24
Refer to the entry for this in Messier Catalogue - M067 (NGC 2682) - May 8, 2018

Ursa Major (UMa)
Time: 9:26 PM + 11:47 PM ADT
Instrument: Visual 
S&T Chart Reference: 31, 32, 33, 43, F
All the stars of the the Big Dipper were easily located and identified. At 11:47 PM, while searching for the comet, I identified stars in UMa that I had not done before - Talitha, Talitha Australis and Muscida. These were used as the start point to star hop to 27 Lynx and CH Lynx to find the comet. The sketch shows the orientation of the constellation for this session. Three stars were almost parallel to the horizon - κ, ι and ο.

   

Corvus (Crow)
Time: 9:32 PM ADT
Instrument: Visual 
S&T Chart Reference: 47
Corvus was first observed at this time. The 5 stars were readily seen. They disappeared / became very faint for a wile in the haze but then became visible again around 1 AM.

Leo
Time: 9:32 PM ADT
Instrument: Visual 
S&T Chart Reference: 34, 35
Only Denebola, Zosma and especially Regulus gave Leo's location away. By 10:00 PM and for the remainder of the session, the remaining stars of the constellation (Chertan and those of the Sickle) came into view. Could follow Leo's path through the night sky.

M53 / NGC 5024
Time: 10:37 PM ADT
Instrument: Telescope
S&T Chart Reference: 45
Refer to the entry for this Messier object in Messier Catalogue - M053 (NGC 5024) - May 8, 2018

M81 / NGC 3031 / Bode's Galaxy
Time: 1:43 AM ADT
Instrument: Telescope
S&T Chart Reference: 45
Refer to the entry for this Messier object in Messier Catalogue - M081 (Bode's Galaxy, NGC 3031) - May 8, 2018.

M82 / NGC 3034 / Cigar Galaxy
Time: 10:15 PM ADT
Instrument: Telescope
S&T Chart Reference: 31
Refer to the entry for this Messier object for how this object was found and its description and sketch - Messier Catalogue - M082 (Cigar Galaxy, NGC 3034) - May 8, 2018.

Leo Minor
Time: 10:52 PM ADT
Instrument: Visual + Binoculars
S&T Chart Reference: 33, 34, 35
Given Leo was relatively high in the sky, I decided to try for Leo Minor.

I used Adhafera and Rasalas as a base for the search. Looked halfway along that line then moved my eyes upwards a bit before putting up my binoculars. Imagine my surprise when I saw 4 stars in a tight cluster in a rectangular formation. Using SkySafariPro, I identified them as 27 LMi, 28 LMi, 30 LMi with the fourth star perhaps having two components - UU LMi and HD90024 - that appeared as one entity in my binoculars.

Draco
Time: 11:17 PM - 11:30 PM ADT
Instrument: Visual + Binoculars
S&T Chart Reference: 41, 42, 51, 52, 61
I have an article from Sky&Telescope (S&T) abut the 16 star doubles in this constellation so decided to get a start on locating them.

Could make out the general shape of the constellation then set to work to find three pairs - binary double (ν1 & ν2) and two optical doubles (16 & 17, and 39 & HD238865).

Guess the others will come later.

 

 
 

Comet: C/2016 N6 (PANSTARRS)
Time: 11:47 PM ADT
Instrument: Visual + Binoculars + Telescope
S&T Chart Reference: 22

I didn't identify all the stars of Lynx, only those relating the position of this comet.

Telescope:
Jerry found it with the telescope first. Knowing the star formation adjacent to comet C/2016 N6, we then looked at SkySafariPro to find the stars then begin the star hopping.

Visually:
1- Talitha and Talitha Australis of Ursa Major (UMa) were on a parallel line with Muscida. We used these as the top reference stars.
2- Below UMa were 2 stars of Lynx that also appeared parallel - 27 Lynx and 24 Lynx.

Binoculars:
At approximately 7 o'clock to 24 Lynx is 23 Lynx. I put my binoculars up to that general area and to may pure joy it was there! The dull grey fuzzy to the right of a star looked like it did in the Meade SCT! Could even see the 5 stars adjacent to it that made it so quick to recognize as the correct location. At 11:47 PM, the comet was 3 o'clock to HD62922 but one hour later was at 6 o'clock.

   
   

Serpens Caput
Time: 12:15 AM ADT
Instrument: Visual 
S&T Chart Reference: 55
This was one of my target constellations for this session. It is located 'below' Corona Borealis and next to Ophiuchus. Amazing that I could see these stars. It took a few seconds to recognize the 3 stars of its head and some of the body stars, but I did see them. I was excited to add another constellation to my list! Also interesting that it terminates in Ophiuchus (unless you prefer that Serpens Caput, the base of Ophiuchus and Serpens Cauda combine into one - Serpens).

   

Corona Borealis
Time: 12:53 AM ADT
Instrument: Visual 
S&T Chart Reference: 53, 55
The wind had died down but it was still cold enough to require my winter coat, hat and mitts. I identified the stars of Corona Borealis as a way of locating Serpens Caput below it.

Crater (Cup)
Time: 12:53 AM ADT
Instrument: Visual 
S&T Chart Reference: 36
Visibility and seeing below 10º on the horizon is non-existent due to haze or fog or clouds. I could see the base of Crater earlier in the evening but the cup stars were elusive.

Jerry and I were the only members at SCO.

Locating M44 led me to the star Acubens (in Cancer) with M67 in close proximity. Not as bright at M44 but more compact, i.e., more stars in the central core. This cluster could easily be found naked eye.

Very windy and cool enough to warrant winter coat, hat and gloves.

I spent part of this evening searching for the stars of Cancer, a constellation I hadn't found before/ While trying to locate the stars visually, I noticed a faint fuzzy in the area. With the binoculars, I found this beauty that completely filled my FOV. No evidence of any true centre, other than some of the stars being slightly closer together.

I was looking through the scope and paying attention to M82. I moved the scope using the hand controller to go south (left) and there was M81.

Both M81 and M82 were in the same FOV, and both were small and medium brightness. Neat to see them both together.

M81 had a dark oval centre and a brighter oval shape around the core.

Temperature: 10º C - 8º C

Very light wind and occasional high haze/cloud.

Winter Circle
Time: 9:12 PM - 9:15 PM ADT
Instrument: Visual + Binoculars 
Was able to see Aldebaran visually; however, by 10:00 PM it had sunk below the horizon. Couldn't find Castor's toe (Propus) visually but did find it with binoculars.

   

Orion
Time: 9:42 PM ADT
S&T Chart Reference: 14, 16, B
Instrument: Visual + Binoculars 
Was looking at Betelgeuse not far up from the horizon. Looked to its right closer to the horizon and found Meissa that is usually seen closer to Bellatrix that was now below the horizon.

With Melissa in the FOV, I found a triangular shape - Meissa, φ1 Orionis and φ2 Orionis.

Auriga
Time: 9:58 PM ADT
S&T Chart Reference: 12
Instrument: Visual 
Located Capella then identified the other 5 stars in the constellation. Did not look at the constellation in any detail.

Leo
Time: 10:00 PM ADT
S&T Chart Reference: 34, 35
Instrument: Visual
All the stars in the sickle were seen visually but as the evening went on μ and ζ were more difficult to see. Denebola, Chertan and Zooms were visible during this observing session.

Venus 
Time: 10:05 PM ADT
Instrument: Visual
Venus was seen as the first "star" in the sky at 8:45 PM about 45º above the horizon.

However, it wasn't until later that I decided to track Venus' orbit as it related to Taurus. Venus about 2º - 3º above the horizon at this time and half way between Elnath (β Tau) and Ain (ε Tau). 

  

Jupiter (in Libra)
Time: 11:19 PM ADT
Instrument: Visual + Binoculars + Telescope
Visual: Saw Jupiter then was able to locate α, β and σ Librae plus Jupiter's orientation to these stars.

Binoculars: @ 10:56 PM - Located Jupiter and noted the location of its 4 Galilean moons.

Telescope: @ 11:19 PM & 11:53 PM - Jerry set up the telescope for me. Saw Jupiter at two times. At 11:53 Io was touching the SW limb. Because of Io's proximity to Jupiter, I couldn't see Io with my binoculars.

 

Minor Planet - Ceres (in Cancer)
Time: 11:15 PM ADT
S&T Chart Reference: 34, 35
Instrument: Telescope
Ceres wasn't bright under these conditions. Couldn't find Cancer so used Leo's Ras Elased Borealis (μ) and Australis (ε) and Pollux. Determined Ceres should be about 1/3 the distance along the imaginary line from ε to Pollux.

Our scope had not been previously aligned; it went in the general direction so had to use the hand control to locate the related stars in Cancer using SkySafariPro and Chart 35 in the S&T Pocket Sky Atlas. Recognized the triangular pattern with the greyish not so bright Ceres at the top.

M5 / NGC 5904
Time: 11:50 PM ADT
S&T Chart Reference: 55, 57
Instrument: Telescope
Used or telescope. Very faint. Saw it better on May 5 with binoculars (refer to General Session - May 5/6, 2018).

Conjunction: Moon - Mars 
Moon: Waning Gibbous (67.4%), rose at 1:36 AM ADT
Identified, Not Observed:
Aquila, Teapot asterism in Sagittarius

Location: on way home from St. Croix Observatory (SCO)
Date: 2018-05-06
Time: 2:30 AM ADT
Instrument: Visual
Transparency: Excellent (5)
Seeing: Excellent (5)
Temperature: 8º C

Very little wind and clear skies.

The Moon rose earlier last evening but we did not notice it while out at SCO. Once we turned onto the road that led to Hwy 101, it was just above the horizon. Once on the 101, the Moon was right in front of us. Jerry noticed a "star" below it that was too bright to be a star. He was correct - it was Mars! The distance between was about x3 the diameter of the Moon or approximately 2.5º apart.

When we arrived home, Mars could be easily seen visually below the Moon.

Jerry went out onto the front lawn and took a photo; I sketched it.

Light wind, no clouds with only occasional very high clouds. Mosquitos have disappeared but the spring peepers continue to serenade us. On this night, I was observing with Melody & Bruce Hamilton, Blair MacDonald, Matt Dyer, Mark Dryden, Jerry and the Desveaux family of four. Lots of observing fun and laughter.

Spring Peepers serenaded us most of the evening. An owl made its presence known in the latter part of the evening. The flies came out as the sun started to set but soon disappeared - and they didn't bite (at least they didn't bite me). A dominant (male? nesting female?) Canada Goose met us on the road near SCO and continued to harass 2 other geese on the pond beside SCO. Bruce brought his "new" scope to try it out. Jerry realized when setting up his scope that he forgot the counterweights so had to go back home to get them.

Humour: Melody had sent an email earlier that had autocorrected "binocs" to "bingos". We used our "bingos" numerous times throughout this session. Laughter about "Bingo Night at SCO" all evening!

Auriga
Time: 8:45 PM ADT
S&T Chart Reference: 12
Instrument: Visual
Identified Capella and the other brightest stars in Auriga. I did not investigate any further.

Winter Circle
Time: 8:45 PM ADT
Instrument: Visual
Could easily identify 4 of the 7 stars in the asterism; the others were hidden by the trees.

Note: I had also seen the Circle while in Chile earlier this year. Whereas the zenith was between Castor and Capella here, it was between Procyon and Sirius in Chile.

   

Leo
Time: 9:42 PM + 11:23 PM ADT
S&T Chart Reference: 47
Instrument: Visual
Regulus appearing gave us a first clue that Leo's stars would soon become visible and we were not disappointed. Regulus to Denebola were easily seen visually. The sickle remained above the horizon for most of this observing session.

11:23 PM:
We searched Leo for Adhafera (ζ Leonis) and 35 Leonis. Adhafera could be seen naked eye. With the binoculars, Adhafera was seen to have another star at 1:30 o'clock to it. Smaller and not as bright. In line with these two stars was 39 Leonis. While looking at the three stars a satellite travelled through. 

Satellite
Time: 11:23 PM ADT
Instrument: Binoculars
I was looking at ζ Leonis, 35 Leonis and 39 Leonis that was in line with the 2 stars. The satellite came into my FOV headed for 39 Leonis then travelled along the line of 3 stars and kept going. Very tiny, very fast.

     
     

Boötes
Time: 9:42 PM ADT
S&T Chart Reference: 42, 44, 53, 55
Instrument: Visual
Arcturus was one of the earliest stars visible. Throughout the night, the stars of the constellation became more visible therefore identifiable. 

Corvus ("Crow")
Time: 9:44 PM ADT
S&T Chart Reference: 47
Instrument: Visual
Actually found this the first time while visiting Florida (May 16, 2017) when it had a different orientation. Corvus was readily seen this evening and was well above the horizon. Used this crater to find and identify Crater.

Ursa Major 
Time: 9:44 PM ADT
S&T Chart Reference: 31, 32, 33, 43, F
Instrument: Visual + Binoculars 
The dipper appeared high in the sky was easily seen visually. Using my binoculars, I located Mizar-Alcor oriented in its familiar way. Bruce also showed the two children and me what the double star looked like in his telescope.

   

Crater ("Cup")
Time: 9:52 PM ADT
S&T Chart Reference: 36
Instrument: Visual
Melody pointed out the base of Crater. It was easy to find as it had a similar shape to Corvus. Once the base was found, we looked for the shape of the cup. Found them all although it took some time as they were all quite faint.

   

Gemini & M35 / NGC 2168
Time: 10:10 PM ADT
S&T Chart Reference: 23, 25
Instrument: Visual + Binoculars 
The main reason for looking for Gemini was to find Castor's toe  star "Propus" in order to locate M35. Castor and Pollux could both be seen easily above the trees but I had to move into the parking lot to see the constellation between the trees at the entry to the Observatory. I focused on Castor.

I followed Castor's foot stars to locate the general area of M35. In my binoculars, it looked like a faint circular fuzzy. With averted vision in the binoculars, I could detect at least 4 brighter stars. the remaining stars were not that significantly dimmer. Couldn't locate it visually this evening. The star 1 Geminorum was below M35.

      

 

M82 / Cigar Galaxy / Bode's Nebula / NGC 3034
Time: 10:15 PM ADT
S&T Chart Reference: 31
Instrument: Telescope 
Bruce was trying out his new telescope and found M82 in Ursa Major. It was exciting to see a new-to-me item. There were 2 bright stars below the Galaxy and 1 at 4 o'clock. I identified them later using SkySafariPro (or at least I think I did).

Canes Venatici
Time: 10:42 PM ADT

S&T Chart Reference: 43, 32
Instrument: Visual + Binoculars 
Melody and I found this constellation again. At this pointing time, it was almost perpendicular to the horizon between Leo and Boötes. Once we identified this constellation, we looked east of Cor Caroli (α CVn) to find the double star CVn 15/CVn 17. In line with them was a third star - HD114905.

   

Coma Berenices (Berenice's Hair)
Time: 10:50 PM + 11:41 PM ADT
S&T Chart Reference: 43, 45
Instrument: Visual + Binoculars
I had identified this constellation in our backyard last Summer but for some reason didn't log it until today. The constellation is 3 stars in a right angle. α and β Comae were easily found between Boötes and Leo. γ took a little longer to locate visually. Used SkySafariPro to locate Com 32 and Com 33/HD111892 west of α Comae.

11:41 PM:Located 17 Comae using gamma as the first star to use in star hopping. Started here then moved the binoculars slowly towards 7 o'clock to γ Comae - et voilá!

   

   

Meteor
Time: 10:50 PM ADT
Instrument: Visual
I was looking at Melotte 111 when I saw a meteor travelling west to west in about a 45º angle directly below the cluster. Very bright, maybe 1 second in duration.

   

M5 / NGC 5904
Time: 11:52 PM ADT
S&T Chart Reference: 55, 57
Instrument: Binoculars 
We used Boötes to find M5. My binocular FOV if 6.5º. We went 2 FOVs plus a bit of a third "down" from Arcturus to find it. M35 was a globular cluster with bright core.

Once found, we used SkySafariPro to identify the stars nearby - 5 Ser, 6 Ser, HD136888, HD136067. Should look at Serpens sometime.

Also refer to Messier Catalogue - M005 (NGC 5904) - May 5, 2018

   

Jupiter in Libra
Time: 11:52 PM ADT
S&T Chart Reference: 46, 57
Instrument: Visual 
Libra was easily found later in this session session as the trees had obscured it from view earlier. Jupiter had moved from being in the centre of the sigma-β line above it. τ Librae was not easily seen but did see alpha and υ. 

Blair MacDonald let me view the bands of Jupiter plus its 4 moons through his scope. Couldn't see the GRS.

Cassiopeia
Time: 12:15 AM ADT
S&T Chart Reference: 1, 3, 72
Instrument: Visual
Just visible above the treeline on the parking lot side of the Observatory. The 5 main stars were easily seen. Attempted to find Kemble's Cascade. melody identified but I unfortunately could not.

Scorpius
Time: 12:15 AM + 1:45 AM ADT
S&T Chart Reference: 56, 58, J
Instrument: Visual
12:15 AM: Noticed Antares and some of the stars SE of it. Because it was so low on the horizon (15º - 20º), the Halifax.Bedford light pollution obliterated the lower stars that could potentially have been seen. Omega1 and Omega2 adjacent to Graffias were also very bright and easy to see on this evening.
1:45 AM: Scorpiuus could only be partially seen as Thad "arrived" around the trees.

Scorpius at 12:15 AM

 

 

 

 

 

 

 

Scorpius at 1:45 AM

Instrument: Visual + Binocular 10x42 IS
Transparency: Very Good (4)
Seeing: Very Good (4)
Temperature: ~ 6º C

Jerry and I woke up shortly after 6 AM. Clear sky with no wind. 

And there before us was the main reason for the early rise. The Zodiacal Light with Mercury rising in its centre over the mountains and Pisces on the edge of its glow was easily seen. For me this was especially exciting as it was the first time seeing the ZL in the southern hemisphere, and to see it rise adjacent to the volcanoes Licancabur and Juriques was breathtaking. 

When Mercury first rose in Pisces, it appeared to be perched on the mountain’s edge like a small ball ready to roll down a knoll. Could see the planet both visually and with binoculars literally in the centre of the base of the ZL.

With Aquarius in the sky, we thought we might be able to see Neptune that was located almost straight up from Mercury. Couldn't quite see it with binoculars but found the general area. It couldn’t be seen visually nor with binoculars, but we did locate it in the photos taken of the zodiacal light. Had we looked up towards the Zenith, we would have found mars in the Teapot.

A wonderful start to the day!

   

Cygnus
Time: 6:20 AM EST
Instrument: Visual + Binoculars 
S&T Chart Reference: 62
I visually followed the Milky Way from the south northward to discover Cygnus. One catch - she was flying in the opposite direction! She looked more live a dive bomber than a bird in flight.

 

   

Coathanger / Collinder 399 / Brocchi's Cluster
Time: 6:30 AM EST
Instrument: Binoculars 
S&T Chart Reference: 65
Having found Cygnus, it was easy to locate Albireo and then this asterism. I
t was upright! You could actually hang a coat on it!

   

We spent the remainder of the morning packing up and arrived at the Calama airport around noon to catch our flight to Santiago. The Andes still had us in awe at its beautiful formations and colour.

San Pedro - April 16, 2018

Melody, Judy, Jerry & Dave standing on the Tropic of Capricorn

What made it particularly exciting on this day was the trip that had us “officially” passing the Tropic of Capricorn – Latitude 25° 26’ 16”. There actually is a sign indicating its location and its where this picture was taken of the 4 Amigos – Melody, Dave, Jerry and me – at 1:10 PM. The desert expanse was mind boggling with very little if any plants on the desert expanses. There was one volcano en route that showed steam coming from its cone, reminding us this is country is part of the Pacific rim volcano ring.

Arrived at Laguna Miscanti (elevation 13,668 ft / 4,164 m ASL), at 1:20 PM. The “lake” was surrounded by mountains and their volcanic peaks, most notably the volcano Miñiques whose lava flow separated Laguna Miscanti from Laguna Miñiques. The first thing we encountered upon arrival was a herd of vicuña on the gentle slopes leading down to the laguna and at water’s edge. 

Humorous Side Story: Our car, driven by Charline, had never been the lead car on excursions so “ate the dust” of the cars ahead of us on the numerous unpaved desert roads. On this day, it was warmer than usual, so Dave requested the air conditioning be turned up. Unexpectedly, a large plume of dust spewed out over Charline and me in the front seat which had us choking. Laughter prevailed throughout the car for several minutes! Dave suggested there must be 4 speeds of air conditioning in Atacama cars – low, medium, high and Atacama dust storm. That had us laughing even more!

Back to the Lodge for supper and for what we thought might be another night under the stars. That was not to be. We were informed upon our return that Latam Airlines was going on strike! Our flights to Santiago and the consequent connection to our flight home on Air Canada were in jeopardy. Jerry spent a lot of time on the computer and phone getting flights for him, Melody, Dave, and me. Thankfully, he was successful.

The airline strike certainly put a damper on that night’s observing. Melody located and viewed the remaining objects she wanted to find but did not have time to sketch them. I just didn’t have the heart for any serious observing other than to stare at the skies for a short period and to realize it may be the last time to see these dark southern skies with all its wonders.

Identified, not Observed:
Coalsack Nebula, Crux, LMC, SMC,

A great disappointment for everyone that the trip was cut short.

Charline, Melody, Judy Jerry beside an ALMA scope

Melody, Judy, Jerry and Charline rose early to arrive in time for the tour bus to the Atacama Large Millimeter/submillimeter Array (ALMA). Due to its dryness, high altitude, scant clouds and scarce radio interference and light pollution from cities, this location was deemed one of the best places on Earth for astronomic observation. The bus turned to go up the mountain range towards the Chajnantor Plateau where the Array Operation Site (AOS) itself was constructed at elevation 16,000 ft / 5,000 m ASL. However, the tour was only going to the Operation Support Facility (OSF) at the lower elevation of 9,515 feet / 2,900 m ASL to reduce altitude sickness risks for staff, volunteers and visitors alike.

One of the 66 AOS dishes was at OSF for repairs, and the two 28-wheel dish transporters were there as well. Talk about luck! It showed us how large these scopes and their transporters to the Array truly are.

ALMA 28-wheel transporter

Back at the Lodge after supper, five of us gathered in the adjacent yard of the ladies' lodge - Melody, Charline, Dave, Jerry and me. I discovered that Leo had a backwards upside-down sickle. In looking closer at Eta Carina, I discovered the keyhole Nebula (NGC 3324). Dave pointed out the “false comet” seen in the tail of Scorpius. In observing it, I was able to identify NGC 6231, Trumpler 24 and Collinder 361. He also showed us the Tarantula Nebula in a 450 mm F5 Dob with 21 mm Ethos eyepiece, then he used OIII (oxygen 3) and UHC (Ultra-high Contrast) to demonstrate the variations in viewing. Fascinating!

Carina
Time: not recorded
S&T Chart Reference: 28, 30, 39, 40
Instrument: Visual
Was again able to find Canopus, β, ε and θ.

Coalsack Nebula
Time: not recorded
S&T Chart Reference: 49, 50
Instrument: Visual
Very easy to find below Crux. It appeared visually as a very dark patch in the Milky Way. Using the binoculars, you could see a few stars peeking through.

Hershel's Jewel Box / NGC 4755
Time: not recorded
S&T Chart Reference: 38
Instrument: Visual
The Jewel Box could readily be found naked eye. Such a wonderful DSO.

Centaurus
Time: not recorded
S&T Chart Reference: 48, 49, 59
Instrument: Visual
I verified I could visually find the stars Rigel, Hader, Birdun, Muhlifain, α Centauri, π Centauri and τ Centauri around Crux. The stars α Centauri and β Centauri were especially bright stars adjacent to the Milky Way.

Omega Centauri
Time: 8:30 PM EST
S&T Chart Reference: 48, 49, 59
Instrument: Telescope 
Dave was using the Lodge's telescope this evening and showed us the  very tight and bright cluster. Viewed it again at 9:19 PM.

Ursa Major
Time: not recorded
S&T Chart Reference: 31, 32, 33, 43, F
Instrument: Visual
Ursa Major was once more pouring out its contents with Mizar-Alcor only about 2º above the horizon. Quite a mind bender! Dubhe was again hidden by the tree adjacent to the Lodge.
Venus
Time: 8:11 PM EDT
Instrument: Visual
Venus could be easily seen in the western sky coming up through Aries between Cetus and Perseus just on the horizon and below Taurus.

Achernar (in Eridanus)
Time: 8:16 PM EST
S&T Chart Reference:  6, 126, 17, 19
Instrument: Visual
Achernar was again only 5º - 7º above the horizon and was very easily found.

Hydrus
Time: 8:16 PM EST
S&T Chart Reference: 10, 20
Instrument: Visual
Could easily make out the Small Magellanic Cloud (SMC) and the triangular formation of Hydrus visually. 

Orion
Time: 8:21 PM EDT
S&T Chart Reference: 14, 16, B
Instrument: Visual
Orion was once more reclining on his side, his sword pointing upwards.

Orion, Lepus, Canis Major, Canis Major

Leo
Time: 8:25 PM EST
S&T Chart Reference: 34, 35, G
Instrument: Visual
Nothing like seeing this with a totally different orientation! What initially alerted me to Leo was the seemingly backwards and upside-down sickle. Using SkySafariPro, I confirmed it was Leo and looked for Denebola. This star was lower than I expected.

47 Tucanae
Time: 8:30 PM EST
S&T Chart Reference: 10, 80
Instrument: Visual + Telescope
I never did find the stars in the constellation Tucana. However, Dave was using 450 mm F5 Dobsonian with a 21 mm Ethos eyepiece. The globular cluster 47 Tucanae has an apparent magnitude of 4.1. Very dense core with less dense edges. It's the second brightest globular cluster after Omega Centauri. 
It looked like a star when located naked eye; didn't use binoculars to view it.

Tarantula Nebula / 30 Doradus / NGC 2070
Time: 8:40 PM EST
S&T Chart Reference: 20, 30
Instrument: Visual + Telescope
This is an emission nebula with an apparent magnitude of 8.0. It is located at the eastern end of the stellar bar of the Large Magellanic Cloud (LMC).

Two clusters are in the Nebula:

  • R136 containing several extremely large stars
  • Hodge 301 Contains 3 red super-giants

We first viewed the Tantula just using the eyepiece provided by the Lodge. Melody then provided 2 filters for comparison

  • OIII (Oxygen 3) filter: it reduced the light and sharpened the features of the nebula.
  • UHC (Ultra High Contrast): it also reduced the light.

Winter Circle - North vs. South Hemispheres
Time: 8:40 PM EST
Instrument: Visual 
I noticed the stars of the Winter Circle were all visible in San Pedro but that they had a slightly different orientation in relation to where they were relative to the Zenith. I drew the Circle as it appeared at this time. Later in the evening in my Lodge, I used SkySafariPro to determine the 'look' of the Winter Circle back home. Here are the comparisons.

Crux + HD111122
Time: 9:23 PM EST
S&T Chart Reference: 38, 49, 50
Instrument: Visual + Binoculars
Located Crux near the Coalsack Nebula then found the 8th magnitude HD111122. It was a red carbon giant located at 9 o'clock to Becruz (β Crux).


Musca ("the Fly")
Time: 9:37 PM EST
S&T Chart Reference: 50
Instrument: Visual
I observed the 6 main stars of Musca visually. None were extremely bright so had to concentrate my gaze to see them.

Apus (Bird of Paradise)
Time: 9:54 PM EST
S&T Chart Reference: 40, 50, 60, 70
Instrument: Visual
Visually located APus by triangulating (sort of) with Circinus and Musca. 
Found the flowerhead formed by δ, β and γ then located α higher in the sky. 

I used my binoculars to view the flower head and discovered the double star δ Apodis (δ1 and δ2). They were parallel to the horizon at this time and δ1 was the larger of the two.

Octans (Octant)
Time: 9:58 PM EST
S&T Chart Reference: 10, 60, 70, 80
Instrument: Visual
This constellation is circumpolar and represents a reflecting octant - a navigational instrument used in astronomy with a 45º arc to measure latitude and longitude.

I was looking in the general area of Hydrus for other constellations. The triangle of the constellation was found but truly had to concentrate in the area of the sky. I used Roy's star map of the southern sky for orientation.

Jupiter (in Libra)
Time: 10:04 PM EST
Instrument: Visual

 

 

 

 

 

 

Very easy to see Jupiter in Libra. It lay on the line (finally!) between α and γ Librae. Very bright and easy to see at 18º above the horizon.

Southern Pleaides / IC 2602 / θ Carinae Cluster
Time: 10:05 PM EST
S&T Chart Reference: 38, 40

Instrument: Binoculars 
The hour glass shape of stars was easily seen beside the row of stars on the right. Very distinctive arrangement of stars.

Boötes
Time: 10:23 PM EST
S&T Chart Reference: 42, 44, 53, 55
Instrument: Visual
At 10:23 PM, I noticed Arcturus in the sky. However, all of Boötes didn't rise above the horizon until 11:20 PM.

Chamaeleon
Time: 10:47 PM EST
S&T Chart Reference: 30, 40, 50, 60
Instrument: Visual
This is a very small constellation that took some time to locate. Australians sometimes refer to it as the "frying pan". alpa and theta form a wide double star. 

NGC 3195 (a planetary nebula) is located near delta but can only be seen by telescope (which I didn't use at this time). Its central star has a magnitude of 15.3.

 

"False Comet" in Scorpius
Time: 11:05 PM + 12:39 AM EST
S&T Chart Reference: 56, 58, J
Instrument: Visual + Binoculars 
By 11:05 PM, all the stars of Scorpius were well above the horizon. Shaula and Lesath were about 2º above the horizon. Dave Chapman pointed out the "false comet" asterism at the top of the curve of the tail. It truly did look like a comet with a series of stars following it. 

Using my binoculars at 12:39 AM from the back patio of our Lodge, it looked like a group of 2 star clusters:
   - NGC 6231 formed the head of the "comet"
   - Open cluster Trumpler 24 and Collinder 362 formed the tail

   

Ara (the "Altar")
Time: 11:10 PM + 11:25 PM EST
S&T Chart Reference: 58, 60, 69
Instrument: Visual + Binoculars 
Ara is the 63rd largest constellation near the "Bend in Scorpius' tail. The name is associated with the altar on which the gods swore allegiance to Zeus before going into battle with the Titans.

11:10 PM:
Used naked eye to locate the constellation and its major stars. Didn't use binoculars to view any of them.

Stars in Ara:
- β Arae: Brightest star, orange supergiant with apparent mag 2.85
- α Arae: 2nd brightest star. Blue-white main sequence star. Fast rotation results in a dense cloud of equatorial emissions. Varying mag 2.76-2.90
- ζ Arae: 3rd brightest star, orange giant with mag 2.11
- δ Arae: Blue-white main sequence star at mag 3.6
- ε Arae: orange giant at apparent mag 4.1
- η Arae: orange giant of apparent mag 3.76

11:25 PM:
Looking through binoculars, I found β Arae where I discovered 3 stars heading down towards a globular cluster. Turns out it was 
NGC 6397 with mag 5.73. Not as compact as Omega Centauri but still very easily seen with a dense core. A pleasant surprise! Had to share this Melody and Charline.

   

Norma (Carpenter's Square)
Time: 11:13 PM EST
S&T Chart Reference: 58, 59
Instrument: Visual + Binoculars 
Easier to find using the "False Comet" in Scorpius as the start point for star hopping. Four of Norma's brighter stars (γ, δ, ε and η) make up the square.

Stars in Norma:
- γ1 & γ2 Normae: Optical double with mag 10. γ2 Normae is a yellow giant and γ1 Normae is a yellow-white supergiant.
- ε Normae: A spectrographic binary with two blue-white main sequence stars at mag 7.5
- η Normae: yellow giant of apparent mag 4.65
- δ Normae: Blue-white mag 4.73. Displays the spectrum of a metal-lined A-type chemically peculiar star.

The Teapot rose out of the southern skies almost straight up with the spout first. An unusual orientation from what we normally see in the Northern Hemisphere. Mars and Saturn rose with the Teapot and I discovered a northern friend

Saturn (near the Teapot)
Time: 12:17 AM EST
Instrument: Visual + Binoculars 
Saturn was visible naked eye and with binoculars. The 4 stars in the Teapot handle were still below our mountainous horizon. Saturn rose on the side of the Teapot near Kaus Borealis with M22 between them. 

   

Mars (near the Teapot)
Time: 12:32 AM - 12:43 AM EST
Instrument: Visual + Binoculars 
The handle of the Teapot had now cleared the mountains and was above the horizon. Both Saturn and Mars were now visible on the lid-handle side of the asterism.

Mars was approximately 2º above the horizon near Nunki and appeared yellow-orange in colour.

   
M8 (Lagoon Nebula)
Time: 12:35 AM EST
Instrument: Binoculars 
I was searching the stars around the Teapot and this jumped out at me. I was not expecting to see M8. It was so exciting to find a familiar DSO!

Instrument: Visual
Transparency: Beyond Excellent (5+)
Seeing: Beyond Excellent (5+)

A group of us in 3 cars headed out for the high Andes at 3 PM – me, Jerry, Melody, Charline, Dave, Fred, Malcolm Park, Greg Merrick and Rajeev Gupta.

Went south past Toconao then turned inland to Talabre Viejo where the paved road became a dirt road, with the road edge ‘curbs’ formed by the sands ploughed up providing guidance there and especially on the return in the dark. The we started the climb the wind-blown virtually smooth hillside. There were several stops for sight-seeing – volcanoes Simba & Pili and Láscar (most active volcano in Chile), and Cerro Tumisa. Láscar was especially interesting with its numerous craters.

We tried to climb the cone of a known crater in the area, but the gas engine cars couldn’t handle the combined altitude and incline, then there it was as we came over the crest of a hill – Laguna Leija! Elevation: 14,117 ft / 4,303 m ASL.

Salt-crusted shorelines surrounded the lake and the cloud-covered Argentine Andes way off in the distance provided a lightning show later in the evening over the Argentinian border but no thunder due to distance away or lower O2 at that altitude. Maybe both.

And was it ever COLD!! With the high-Andean winds and a big temperature drop, every piece of winter gear was necessary. The lee of the cars provided some protection. The Milky Way above the mountains with the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) with their reflections in the waters of Leija were breath-taking! No twinkling at this elevation! Stars were like small diamonds – so bright and so clearly defined. Left us speechless as we took in yet another “oh, wow” moment. 

Circinus, Crux & Triangulum Australe
Time: not recorded
S&T Chart Reference: 48, 50
Instrument: Visual
I located Crux and showed Melody and Charline how to find Circinus and Triangulum Australe. With the stars being so clearly seen no matte where you looked, it was an easy exercise to complete - and then duck down behind the car to get out of the wind!

Jupiter (in Libra)
Time: not recorded
Instrument: Visual
I located Libra and noted the location of Jupiter just below the imaginary line between α Librae and γ Librae. It had moved sightly closer to that line compared t0 the night before. 

Herschel's Jewel Box / NGC 4755
Time: not recorded
S&T Chart Reference: 48, 50
Instrument: Visual
Having found Crux and the Coalsack Nebula, it was very easy to visually locate and identify the Jewel Box. Such a beautiful bright entity.

Andean flamingo in Laguna de Chaxas; volcano Quimal in the background
We once again had a road trip, this time travelling 62 km from San Pedro de Atacama to Laguna de Chaxas (Chaxas Lake) in the Reserva Nacional “Los Flamencos”. On the way back, Charline (aka driver/tour guide) remembered a side trip she had taken on a previous Atacama trip to a beautiful valley oasis – Valle de Purques – on the mountainside from where we could see Licancabur, Juriques and the ALMA Operations Support Facility (OSF). One would never know this amazing, fertile place was in the middle of the desert where a farmer was obviously growing some crops (including corn) along the stream bed!

Set up for the observing session around 8:00 PM.  No clouds or wind. Clear skies.

Some of this session was with Melody, Dave and Charline; Jerry visited occasionally between times when he had to deal with his astroimaging equipment. Went back to our lodge at midnight when I became too chilled to remain outside. 

Carina (the "Keel")
Time: not recorded
S&T Chart Reference: 28, 30, 38, 39, 40
Instrument: Visual
The triangle formed by α, β and ε Carinae was readily identified. θ Carinae was identified because of the visibility of the Southern Pleiades.

Large Magellanic Cloud (LMC) / PGC 17223 / Nubecular Major
Small Magellanic Cloud (SMC) / PGC 3085 / Nubecual Minor
Time: not recorded

Orion & M42 (Orion Nebula)
Time: not recorded
S&T Chart Reference: 14, 16, B
Instrument: Visual + Binoculars 
Orion was once again seen visually lying on his side; the belt and sword were very visible. I used my binoculars to see the nebulosity of M42 - beautifully clear!

Coalsack Nebula & Crux
Time: not recorded

S&T Chart Reference: 49, 50
Instrument: Visual
Interesting that I found this dark area that I thought was the nebula then verified I was the correct by finding Crux adjacent to it. Stars of Crux very bright and easily picked out on the 'border' of the Coalsack.

Corvus (Crow)
Time: not recorded
S&T Chart Reference: 47
Instrument: Visual
All 5 stars easily identified in the dark skies.

Musca (the "Fly" or "Mosquito")
Time: not recorded
S&T Chart Reference: 50
Instrument: Visual
All the bright stars easily identified for this constellation.

Herschel's Jewel Box / NGC 4755
Time: not recorded
S&T Chart Reference: 38
Instrument: Visual
The Jewel Box was easily located visually. Didn't use binoculars to view this splendid cluster.

Jupiter (in Libra)
Time: not recorded
Instrument: Visual
Jupiter was once again very bright. It was about 18º above the horizon in Libra.

Centaurus
Time: 9:52 PM EST
S&T Chart Reference: 48, 49, 59
Instrument: Visual
While with Charline, Dave and Melody, I found Crux then identified all the stars of the Centaur. Such an interesting constellation. α Centauri and β Centauri were easily seen in the night sky!

Omega Centauri
Time: not recorded
S&T Chart Reference: 48, 49, 59
Instrument: Visual + Binoculars 
Held up the binoculars after visually locating the cluster - and found it. Such a thrill to see!

  

Lupus (the Wolf)
Time: 10:02 PM EST
S&T Chart Reference: 48, 59
Instrument: Visual
Charline introduced me to this constellation and showed me where the stars were located. Not all were easily seen on the edge of the Milky Way.

Triangulum Australe
Time: 10:03 PM EST
S&T Chart Reference: 60
Instrument: Visual
This was also on the list of constellations I wanted to find tonight. I found the Triangulum which then allowed me to find Circinus.

Stars in Triangulum Australe:
- α Trianguli Australis (Atria): orange second-magnitude giant star at mag 1.91
- β Trianguli Australis: double star. Primary is a main-sequence star with mag 2.38. Companion is a 13th mag star.
- γ Trianguli Australis: white main sequence star with mag 2.87
- δ Trianguli Australis: 4th brightest. Yellow giant star at mag 3.8
- ε Trianguli Australis: optical double. "A" is an orange K-type sub giant wth mag 4.11. "B" (or HD138510) is a white main sequence star ar mag 9.32

Note: Atria = A(lpha) Tri(anguli) A(ustralis)

    

Circinus (Compass)
Time: 10:09 PM EST
S&T Chart Reference: 48, 50
Instrument: Visual
This was also on the list of constellations I wanted to identify tonight. It was located between Triangulum Australe and Centaurus. It was also very small and faint. 

Stars in Circinus:
- α Circini: brightest star at mag 3.19, slightly variable
- β Circini: white sequence star with mag 4.07
- γ Circini: binary star with mag 4.51 (blue component) and 5.5 (yellow star)
- δ Circini: multiple star with components mag 5.1 and 13.4; orbits around a common centre of gravity every 3.9 days
- θ Circini: an irregular variable with mag 5.0-5.4

      

Lepus (the Hare)
Time: 10:15 PM EST
S&T Chart Reference: 16
Instrument: Visual
Another on the list of constellations I wanted to identify while in the Atacama. I had never observed it at home. It was interesting to see it on its side per se and so easily seen beside the reclined Orion.

Stars in Lepus:
- α Leporus (Arneb): brightest star at mag 2.589. It's a very old and dying star.
- β Leporus (Nihal): orange giant with apparent mag 2.84. It's a double star, maybe binary.
- ε Leporus: orange giant with mag 3.166
- μ Leporus: blue-white sub-giant with apparent mag 3.259
- η Leporus: yellow white dwarf with mag 3.719
- δ Leporus: orange sub-giant with mag 3.81
- γ Leporis: yellow-white main sequence star with mag 3.59
- κ Leporis: binary star with mag 4.43 and 7.00
- λ Leporis: blue-white sub-giant star with apparent mag 4.29
- θ Leporis: blue-white main sequence star with mag 4.67

NOTE: This is the Southern Hemisphere orientation.

   

Asterism in Lepus - Known as the Throne of Jawza or the Camels (from the Arabic phrase meaning "camels quenching their thirst")

         

Vela (the "Sails")
Time: 10:44 PM
S&T Chart Reference: 28, 29
Instrument: Visual
Another constellation I had hoped to find this evening. 32nd constellation in size. This was once a section in the much larger Argo Navis. 

To find it, it helped knowing its relative position to Carina and the η Carina Nebula. Still needed to stare a long time at that part of the sky to determine its general location using the shape of the constellation, then finding the specific stars. Didn't locate them all initially but did find most as the night wore on.


*Suhail has the modern name of "Regor" ("Roger" spelled backwards). It honours Apollo 1 astronaut Roger Chaffee. Originally inserted in NASA star charts by Gus Grissom as a practical joke, but has endured as a memorial to both men who died in the Apollo 1 fire.

 

Volans ("Flying Fish")
Time: 10:50 PM
S&T Chart Reference: 30
Instrument: Visual
Yet another constellation only list to find this evening. 76th constellation in size.

Stars in Volans:
- β Volantis: Brightest star in the constellation; orange giant with mag 3.77
- α Volantis: It's an A-type chemically peculiar star at mag 4.00
- γ Volantis: Binary star. Primary is an orange giant with mag 3.378; second star is a yellow-white main sequence stat with mag 5.68.
- δ Volantis: 4th brightest, Yellow giant star at mag 3.8
- ε Volantis: Triple star system with an apparent mag of 4.35
- ζ Volantis: Binary star (orange giant with a 10th mag companion) with apparent mag 3.93

Puppis (the "Poop Deck" or "Stern")
Time: 11:25 PM
S&T Chart Reference: 26, 27, 28, 29
Instrument: Visual
This is a very large constellation that was once part of the larger constellation Argo Navis before it was divided into Puppis, Carina, and Vela. This was on the list of constellations I wanted to identify while in the Atacama, especially since I had seen Azmidis, Asmidi (ξ), and what I believed was Ι Puppis (but cannot now find in star charts) in November 2017 at Peggy's Cove. It was found and the main stars identified.

 

Stars in Puppis:
- ζ Puppis (Naos): variable star at mag 2.21
- ξ Puppis (Azmidi): very luminous yellow Supergiant star, mag 3.34
- π Puppis (Ahadi): less laminar orange-red Supergiant star with mag 2.71
- ρ Puppis (Tureis): variable double star, mag 2.83
- τ Puppis: Orange-red binary star with mag 2.94
- ν Puppis: blue giant star, mag 3.17
- σ Puppis (Hadir): orange-red binary star system, mag 3.25
- a Puppis: double star, mag 3.62
- c Puppis: variable star, mag 3.62
- HR 2948: Variable double star, mag 4.4
- L2 Puppis: Red variable star

Ursa Major
Time: 11:20 PM
S&T Chart Reference: 31, 32, 33, 43, F
Instrument: Visual
As was the case last evening, the Dipper was pointing down with Dubhe once more partially shielded by the trees. Mizar and Alcor were once again only about 2º above the horizon.

 

Boötes
Time: 11:25 PM
S&T Chart Reference: 42, 44, 53, 55
Instrument: Visual
Noticed a very bright star in the NE. Used SkySafariPro to determine it was Arcturus. Looked more towards the north, found Ursa Major then "arced to Arcturus" to confirm. The surprise for tonight was the orientation of Boötes. It was in essence upside-down, looking like a clip-on necktie versus the kite we see up North.

We were on the road at 7 AM for a 2-hour drive (98 km/ 61 miles) drive to the El Tatio geyser field – elevation of 14,173 feet / 4,320 m ASL). We saw the sun rise over the Andes and mention numerous vicuñas along the roadways. What sights! Then there it was - El Tatio! It’s an amazing place with over 80 active geysers – geyser cones, fumaroles, steaming soil, mud pots, and sinter terraces. It’s the 3rd largest geyser field in the world and the largest in the Southern Hemisphere. Back into San Pedro for a Chicken enchilada crema supper– fabulous! We also picked up some empanada pollo for tomorrow.

El Tatio geyser field
El Tatio geyser cone

We spent the rest of the evening at the Lodge observing the night skies. I managed to get most of the targets for this evening. One pleasant surprise was Scorpius that rose on its side well above the horizon. I also watched as α Crux rotated 90° in orientation for “SE” to “SW”; read about it below. When I became chilled enough, it was time for bed.

Centaurus
Time: not recorded

S&T Chart Reference: 48, 49, 59
Instrument: Visual
Group observing with Dave, Melody and Charline. After locating Crux, I verified I could find the stars in Centaurus with α and β being especially bright.

Omega Centauri
Time: not recorded
S&T Chart Reference: 48, 49, 59
Instrument: visual + Binoculars 
Once again held up the binoculars after visually locating the cluster - and found it. Such a thrill to see!

Coalsack Nebula
Time: not recorded

S&T Chart Reference: 49, 50
Instrument: Visual + Binoculars 
Very easy to find below Crux. To the naked eye, it was an easily found large dark area in the Milky Way.  With Binoculars, you could see a few stars.

Hydrus
Time: not recorded
S&T Chart Reference: 10, 20
Instrument: Visual 
Identified a couple of stars that were at an angle to each other and to the left of the SMC. Identified the tree stars of this constellation - α, β,  and γ.

Carina (the "Keel")
Time: not recorded
S&T Chart Reference: 28, 30, 39, 40
Instrument: Visual
The triangle formed by α, β and ε Carinae was readily identified. θ Carinae was identified because of the visibility of the Southern Pleiades. I attempted to visually locate all the stars in this constellation but did not succeed.

Eta (η) Carina / NGC 3372
Time: not recorded
S&T Chart Reference: 38, 39, 40
Instrument: Visual + Binoculars 
Located the nebula with my binoculars.

Southern Pleiades / IC 2602 / θ Carinae Cluster
Time: not recorded
S&T Chart Reference: 38, 40
Instrument: Visual + Binoculars 
Used binoculars to view the Southern Pleiades. Located it first visually before using the binoculars.

Large Magellanic Cloud (LMC) / PGC 17223 / Nubecular Major
Small Magellanic Cloud (SMC) / PGC 3085 / Nubecual Minor
Time: ~ 9:19 PM EST 
S&T Chart Reference: 10, 20, 30
Instrument: Visual
The LMC and SMC are ever present in the night skies. The "oh wow" moments never stop. The galaxies seem to swirl around the crown of the tree in the field adjacent to our Lodge, with the SMC disappearing in its branches in the latter part of the evening.

Corvus
Time: 9:20 PM EST
S&T Chart Reference: 47
Instrument: Visual
I identified all but Alchiba. Hope to find it tomorrow.

Crux
Time: 9:25 PM +11:13 PM (+ photo at 4:03 AM) EST
S&T Chart Reference: 38, 49, 50
Instrument: visual + Binoculars 
Observing with Melody, Charline and Dave. Throughout the evening was able to observe the shift in orientation of Crux.

9:25 PM: looked like γ Crux was pointing to 10 o'clock.
11:13 PM: looked like γ Crux was pointing to 11 o'clock.
4:03 AM: In a photo Jerry took at 4:03 AM, γ Crux was pointing to 2 o'clock.

   

Herschel's Jewel Box / NGC 4755
Time: not recorded
S&T Chart Reference: 38
Instrument: Visual + Binoculars 
Used my binoculars to locate beta Crux then found the Jewel Box. Such a beautiful and bright teardrop-shaped nebula. This nebula was appropriately named.

Orion & M42
Time: not recorded
S&T Chart Reference: 14, 16, B
Instrument: Visual
Still surprised to see the Hunter on his side, almost as if having a nap while traversing the southern skies. The jewel in his sword (M42) was easily identified.

Venus (in Aries)
Time: 8:00 PM EST
Venus Set: ~ 8:35 PM EST
Instrument: Visual
Venus was only about 2º above the horizon. Very bright and no twinkling.

Jupiter (in Libra)
Time: 11:16 PM EST
Instrument: Visual
Jupiter had moved slightly closer to the imaginary line between β and γ.

 

Ursa Major
Time: 10:58 PM EST
S&T Chart Reference: 31, 32, 33, 43, F
Instrument: Visual
It was interesting to see this rise above the horizon - upside down. Initially, Dubhe hid behind the branches of a tree but soon made its appearance. Mizar-Alcor easily seen with binoculars.

   

Scorpius
Time: 11:01 PM EST
S&T Chart Reference: 56, 58, J
Instrument: Visual
First saw this orientation here in the Atacama on April 9 during the sky tour with Alain Maury and casually observed it on the 10th.

All of Scorpius was above the sky line! Haven't seen it all above the horizon since Dead Horse Point State Park, Utah (May 2017) and Acadia National Park, Maine (August, 2017). Although the sketch shows it at an angle, it truly was lying on its side along the horizon with θ and ι only 1º above the horizon. Despite the lower declination, I was able to see how close Shaula and Lessath really are.

San Pedro - April 10, 2018

Constellations: Canis Major, Carina ("Keel"), Centaurus, Crux, Hydrus, Musca, Orion, Ursa Major
Galaxies: 
Large Magellanic Cloud (LMC), Small Magellanic Cloud (SMC)
Nebula: Coalsack, Eta Carina, NGC 3372, Herschel's Jewel Box/NGC 4755
Stars: Achernar, Canopis, θ Carina, α Centauri, β Centauri
Clusters: 
Omega Centauri, Southern Pleiades (IC 2601)
Planet: Jupiter, Venus
Messier Object: M42 (Orion Nebula)

Location: San Pedro de Atacama, Chile @ SPACE Lodge
Date: 2018-04-10
Time: 8:00 PM - 11:00 PM EST
Instrument: Visual + Binocular 10x42 IS + Televue 60 with 17.3 mm eyepiece
Transparency: Very Good (4)
Seeing: Very Good (4)
Temperature: ~ 8º C

No clouds or wind and humidity is not evident. Clear skies.

In the early afternoon, we visited the ancient village of Tulor de Aldea. Around 4 PM, it was decided the excursion to Valle de la Luna was postponed to another day because of incoming clouds from all sides (the only time we saw cloud cover the whole trip). Without the sun, we would not be able to see the effect on the Valley as the sun set. Consequently, I spent the early evening viewing the night skies with Melody, Charline, Dave and occasionally Jerry (who visited between adjustments to his astroimaging equipment). Headed to bed at 11 PM.

Musca
Time: not recorded
S&T Chart Reference: 50
Instrument: Visual + Binoculars
Using the binoculars, I was able to locate 6 main stars very easily - α, β, λ, ε, δ, γ. I was observing next to Lodge #2 with Melody, Charline Norgrove and Dave.

Coalsack Nebula
Time: 8:09 PM EST 
Instrument: Visual
S&T Chart Reference: 49, 50
Easy to find what appears to be a black empty space below Crux.

Venus (in Aries)
Time: 8:09 PM EST 
Venus set: 8:35 PM EST
Instrument: Visual
Venus was observed every evening.

Herschel's Jewel Box / NGC 4755
Time: 9:19 PM EST 
S&T Chart Reference: 38
Instrument: Visual + Binoculars + Televue 60
The 4.5 magnitude cluster was named after Herschel because he determined the positions of 100 stars within the cluster. In binoculars, this appeared as a teardrop shape just below Becrux in Crux and above the Coalsack Nebula. 

In looking through Charline's telescope, it was so easy to see the strs differentiated in the teardrop. You could also see where the stars were brighter/clustered in the open cluster and where they were fainter.

Large Magellanic Cloud (LMC) / PGC 17223 / Nubecular Major
Small Magellanic Cloud (SMC) / PGC 3085 / Nubecual Minor
Time: ~ 9:19 PM EST 
S&T Chart Reference: 10, 20, 30
Instrument: Visual

The LMC and SMC are ever present in the night skies. They continue to provide "oh wow" moments every time they are seen. Guess I just can't believe I'm seeing them.

α Eridani / Achernar (in Eridanus)
Time: 9:29 PM EST 
S&T Chart Reference: 6, 16, 17, 19
Instrument: Visual + Binoculars
Dave Chapman pointed this out to us to ensure we saw it before it set. It was twinkling about 5º above the horizon. Achernar is the bright star at the end of Eridanus ("river").

Binary star system with a companion known as Achernar B. Magnitude 0.45, 9th brightest star in the night sky. Tiny but regular variations over 1.26 days caused by actual complex pulsations, or by rotation bringing dark star spots in and out of view.

Orion & M42
Time: 9:51 PM EST
S&T Chart Reference: 14, 16, B
Instrument: Visual + binoculars + Televue 60
It was interesting to once again see the Hunter on his side as compared to standing upright in the Northern Hemisphere. M42 easily identified.

Charline told us the 3 stars in Orion's Belt were known as the "Las Tres Marías" (the 3 Marys), i.e., the 3 Marys who were present at Christ's crucifixion.  She then showed us M42/M4 3 through the scope - a very nice version to see. Also used my binoculars to compare the size and nebulosity.

Centaurus
Time: 9:32 PM EST 
S&T Chart Reference: 48, 49, 59
Instrument: Visual
Alain at the Atacama Lodge had given us an orientation and showed how the Centaur circled around Crux. After the orientation, I went back to our Lodge and was able to identify 12 of the 13 stars in the traditional ones of the constellation. α Centauri and β Centauri are very bright and easily seen.

Omega Centauri
Time: not recorded
S&T Chart Reference: 48, 49, 59
Instrument: Visual + Binoculars 
Visually star-hopped to approximate the location of the cluster. Held up my binoculars and found it immediately in my eyepiece. What a glorious DSO! So big. So bright.

 

Canis Major
Time: 9:55 PM EST 
S&T Chart Reference: 27
Instrument: Visual
I noticed the bright star above Orion. The line of stars in Orion's Belt pointed to it so knew it was Sirius. It took a few mments to get my head around the orientation, and did find the major stars of this constellation. I had noticed Sirius the night before but had not taken the time to identify the other stars.

Carina ("Keel")
Time: 10:05 PM EST 
S&T Chart Reference: 28, 30, 39, 40 
Instrument: Visual

Carina is one of 3 parts that was once the large constellation Argos Navi. It is circumpolar and is the 3rd largest constellation in the sky. It was very easy to identify as were ε and β. The other stars were very difficult to identify. θ Car was easier to find because of its proximity to the Southern Pleiades. Canopus is the next brightest star in the sky next to Sirius and never sets below the horizon. Absolute mag -5.53.



Stars in Carina:
- η Carinae is a star system composed of at least 2 stars. It was easier to find once I found the nebula.
- β Carinae (Miaplacidus) is the 29th brightest star in the sky. Mag 1.67
- ε Carinae (Avior) is the 84th brightest in the sky. Mag 1.86. It is a double star that regularly eclipse each other, therefore have variations in luminosity of 0.1 mag.
- ι Carinae is the 68th brightest star. Mag 2.21
- θ Carinae the the most prominent star in the Southern Pleiades. Mag 2.74

Eta (η) Carina / NGC 3371
Time: 10:05 PM EST 
S&T Chart Reference: 28, 30, 39, 40 
Instrument:  Binoculars + Televue 60 

Eta Carina is an emission nebula. I had been looking at Carina in an attempt to find all of the constellation. Charline was able to locate the η Carina nebula in her telescope and shared the sight with us. Almost looks like the Trifid Nebula.

Apparently, this nebula is 4x the size and even brighter than the Orion Nebula. Within this nebula (we later discovered) is the Keyhole Nebula, located just to the right of η Carina.

Following this viewing, I looked at the nebula with the binoculars.

 

 

Southern Pleiades / IC 2602 / θ Carina Cluster (in Carina)
Time: 10:10 PM EST 
S&T Chart Reference: 28, 30, 39, 40 

Instrument:  Binoculars / Televue 60

After I saw what looked like an hour glass on the left and other stars to the right in my binoculars, Charline showed me the Southern Pleiades in her telescope. The binocular view wasn't as good as the scope's (obviously!).

NOTE: θ Carina is the brightest star at mag 1.9. It also has the obscure name of "Vatharz Posterior" meaning "succeeding one of the waterline". This probably refers to the waterline alongside of what was once referred to as the Argo Navis.

Jupiter (in Libra)
Time: 10:22 PM EST 
Instrument:  Visual 

The constellation Libra was easily located after noticing bright Jupiter also in the same portion of sky. Jupiter was located a little below the imaginary line from β to γ Libra.

 

Hydrus (Water Snake)
Time: 10:24 PM EST 
S&T Chart Reference: 10, 20 
Instrument:  Visual 

I was looking to see if Achernar had gone below the horizon when I saw a couple of stars at an angle to each other above and to the left of the SMC. SkySafariPro identified the pair as 2 stars of Hydrus.


Stars in Hydrus
:
- α Hydri: white sub-giant star of mag 2.9
- β Hydri: brightest star n the constellation; yellow sun-like at mag 2.8
- γ Hydri: semi-regular variable red giant at mag 3.26-3.33

Ursa Major
Time: 10:58 PM EST 
S&T Chart Reference: 31, 32, 33, 43, F

Instrument:  Visual + Binoculars 
It was interesting to watch this rise above the horizon upside-down. Initially Dubhe hid behind the branches of the tree but it soon made its appearance. Mizar and Alcor were easily seen with binoculars but they, too, were oriented differently from the northern hemisphere - and only 2° above the horizon.

Light wind, no clouds, no flies.

After supper, we had a private tour of Alain’s telescope field. Melody and Dave didn’t feel perfectly well but Jerry and I had altitude sickness meds and felt fine. Alain (Owner of the SPACE Lodge) introduced us to the Southern Hemisphere skies and provided our first viewing of some of the southern wonders overhead. I was amazed at the size of the Coalsack – about 7° x 5° in the sky! Dave also explained how to find the globular cluster Omega Centauri (aka NGC 5139) – the largest globular cluster in the Milky Way. Melody gave us a Southern Hemisphere Star Chart that Bruce had found online. Came in handy throughout the trip. I became chilled so headed back to our lodge to get warmer clothes but decided instead to just go to bed. Lights out at 10:30 PM.

Venus
Time: 8:09 PM EST 
Venus Set: 8:35 PM EST
Instrument: Visual
Venus (in Aries) was observed every evening we stayed in the Atacama Desert. We saw it as it began its descent towards the horizon.

Orion
Time: 8:35 PM EST 
Instrument: Visual
S&T Chart Reference: 14, 16, B
Orion stars were located but the Hunter was lying on his side with his sword pointing upwards. Quite a different look from what we see "up north". M42 was still as bright as ever and easily identified.

Coalsack Nebula
Time: 9:15 PM EST 

Instrument: Visual
S&T Chart Reference: 49, 50
You can't miss this nebula below Crux - it's massive, covering an area of 7º x 5º in the sky! Consists of thick clouds of dust and gas - the perfect materials for star formation. It is very dark. I will have to use binoculars next time to see what I can see.

   

Large Magellanic Cloud (LMC) / PGC 17223 / Nubecular Major
Small Magellanic Cloud (SMC) / PGC 3085 / Nubecual Minor

Time: 9:19 PM EST 
Instrument: Visual
S&T Chart Reference: 10, 20, 30
The SMC was ~ 20º below the LMC at about 6:30 o'clock. The LMC and SMC are irregular galaxies that look more like nebula at first glance.

LMC:
Magnitude: 0.9
Size: 10.75º x 9.17º and contains a very prominent warped bar at its centre with a spiral arm tipped at 35º
4th largest Galaxy in the Local Group after M31, Milky Way and M33 (Triangulum Galaxy)

SMC:
Magnitude: 2.7
Size: 5º 20' x 3º 5' and contains a central bar structure (that may have once been a barred dwarf spiral galaxy).

 

PM45 (Pleiades)
Time: 9:30 PM 
Instrument: Visual + Binoculars 
S&T Chart Reference: 14, 15, A

Located this open cluster visually. It was very bright using the binoculars; the stars and nebulosity were fairly clear in the FOV. I didn't sketch it this time but hope to in the near future.

Crux / Southern Cross
Time: 10:10 PM EST 
Instrument: Visual
S&T Chart Reference: 38, 49, 50
Amazing to see Crux for the first time! So clearly visible even though it's the smallest of the 88 constellations.

Stars of Crux:
- Acrux (α Crucis): Blue white double star, 4.4 arc second separation. 14th brightest in the sky. 
Magnitude 1.4 & 1.9
- Mimosa / Becrux (β Crucis): White star. 20th brightest star in the sky. Magnitude 1.30
- Gacrux (γ Crucis): Red Giant belonging to the spectral class M4III. 26th brightest star in the sky. Magnitude 6.4
- Imai (δ Crucis): β Cephei type variable star. Magnitude 2.775

 

 

Omega Centauri / NGC 5139 (in Centaurus)
Time: 10:16 PM EST

Instrument: Visual + Binoculars + TeleVue 60
S&T Chart Reference: 48, 49, 59
Omega Centauri, a globular cluster in Centaurus, is the largest globular cluster in the Milky Way and is easily seen naked eye. The core of the cluster is very tight and almost looked like a solid body. The outer edges of the cluster were still quite compact with many, many stars near the tight core - all in all, quite a compact and bright cluster.

 

How to Find Omega Centauri:
1- Locate α Centauri and β Centauri, and the distance between them.
2- Visually go up from there an equal distance.
3- The go about 60º using the same length from that previous point.
4 - Et voilá!

Corvus
Time: not recorded

Instrument: Visual
S&T Chart Reference: 47
Although I had first seen this constellation in Florida, it was much higher in the sky in Chile.

Stars of Corvus:
Gienah: Brightest at mag 2.6, blue-white giant.
Algorab: wide binary system at mag 3 & 8
Alchiba: 5th brightest star even though it has the alpha designation.

   

Musca ("the fly")
Time: 9:45 PM EST
Instrument: Visual
S&T Chart Reference: 50
This constellation was pointed out during the general tour of the night sky by Alain. Fairly close to the Coalsack Nebula and Crux. Interesting that 3 of its stars have planets.

Musca Stars:
- α Muscae: blue-white star with mag 2.7
- β Muscae: Binary star system composed of 2 blue-white main sequence stars
- γ Muscae (tail of the fly): blue-white star that varies between mag 3.84-3.86 over 2.7 days
- ζ2 Muscae: white main sequence star. Part of a triple star system with faint companions at 0.5 and 32.4 arc seconds distance.
- η Muscae: Multiple star system, 2 main components forming an eclipsing binary with mag 4.77 that dips by 0.05 mag every 2.39 days.
- δ Muscae: orange giant at mag 3.62
- ε Muscae: red giant and semi-regular variable. Mag 3.99-4.31 over 40 days
- μ Muscae: orange giant mag 4.7.1-4.76; slow irregular variable
- λ Muscae: 3rd brightest star in the constellation; white main sequence star

Very warm with no breeze or clouds.

Large Magellanic Cloud (LMC) / PGC 17223 / Nubecula Major
Time: 9:45 PM - 11:45 PM EST 

Instrument: Visual
S&T Chart Reference: 20, 30
We had just arrived in Atacama then went for dinner. Upon return to the Lodge, we opened our car doors to be greeted by the southern Milky Way and the Large Magellanic Cloud. So much larger than envisioned! This was our first “OH, WOW!” It literally kept me planted beside the car for a few seconds as I attempted to take it all in. "Large" as a descriptor doesn't do the LMC justice. It was so much larger than the photos suggest.

The night sky was so expansive with no interference from trees, buildings, or clouds. So much to explore! It was so different from home. Low humidity meant we didn't have to use warmers for telescope lenses nor to protect any books or papers we were using. Virtually no wind at night but cold, nonetheless. Dave led us to discover the Alpha Centauri Globular cluster. Another "Oh, WOW!" moment.

Bedtime at 12:30 AM.

NOTE: The LMC and SMC were named after the explorer Ferdinand Magellan who brought this to European knowledge in 1519.

Small Magellanic Cloud (SMC) / Nubecula Minor
Time: 9:45 PM - 11:45 PM EST

Lunar Session - February 3-4, 2018

This session was devoted to lunar observing.

Lunar Phase: Waning Gibbous (83.4%)
Q-Day: -4

Moonset: 9:27 AM       Moonrise: 9:22 PM            
Sunrise: 7:32 AM          Sunset: 5:26 PM

Location: Home

Equipment: Visual + Binoculars 10x42 IS
Transparency: Good (3)
Seeing: Good (3)
Temperature: -14º C to -11º C

Clear skies except for a few bands of cloud to the south and a few near the Moon. Seeing and visibility decreased since last evening.

The Moon over the past 2-3 nights travelled above Regulus in Leo to beside Zaniah in Virgo. Couldn't see the majority of stars in Virgo but could see what I thought was Heze (ζ Virginis), a double star. Because of the clouds, the Moon had a hazy glow around it. With the binoculars, I could barely make out the features.

Couldn't make out the double star in binoculars. Could not see Spica due to neighbour's house blocking the view from the horizon.

Time: 7:36 PM
Temperature: -9º C.

Clear skies, little wind. First saw the Full Moon as we pulled out of our daughter's driveway. It was in front of us most f the way back home. Shielding my eyes from the Moon's light, I could see Regulus (Note: I was the passenger in the car, not the driver.). Sky Safari Pro was used to determine the Moon's position relative to Leo, and to Cancer and Hydrus.

Home:

Time: 10:06 PM
Temperature: -11º C.

Skies still clear, little if any wind. A bit of high cloud was beginning to obscure views of stars. Winter Circle was easily identified along with the major stars in Orion.

Easily viewed the Moon from our side deck. Used my binoculars to determine the orientation of the Moon.

Conjunction: Jupiter-Venus (in Virgo)
Time: 5:50 AM - 7:05 AM AST
Equipment: Visual 

Planets came up and peeked through the clouds before rising above them. Venus was very bright in comparison. For some reason, I could not find Mars near the star Porrima ("above" Spica in the morning skies).

Winter Circle
Time: 6:15 AM AST
Equipment: Visual 
The major stars of Auriga, Taurus, Orion, Canis Major, Canis Minor and Gemini could be seen naked eye. Pointed out all the circle stars to Brianne.

M42 & M43
Time: 6:15 AM AST
Equipment: Visual + Binoculars 
S&T Chart Reference: 16, B
I used my new binoculars to look at M42 and M43  in Orion, and for the first time could see the nebulosity around the star clusters. M42 was seen as a separate entity from M43. The central star area was quite discernible as was the surrounding nebulosity. A very different view. 
So exciting!

   
 

Puppis
Time: 6:30 AM AST
Equipment: Visual + Binoculars, 10x30  IS
S&T Chart Reference: 26, 27, 28, 29
This constellation is normally seen in the Southern Hemisphere, and represents the stern of a ship. It was part of a larger constellation "Argos Navis" before it was divided into Puppis (the poop deck), Carina (the keel) and Vela (the sails). I saw a triangle below Sirius that was not much above the horizon. This unknown triangle piqued my curiosity. Had to use SkySafariPro to help establish the identify of the three stars. Surprised, or what!

Taurus & the Hyades
Time: 6:30 AM AST
Equipment: Visual + Binoculars, 10x42  IS
S&T Chart Reference: 14, 15, A
Aldebaran was still bright in the morning sky so showed Brianne some of the stars in the constellation but focused on the Hyades open cluster, using my new 10x41 IS binoculars. What a difference from the 10x30 IS!!

M45 (Pleaides)
Time: 6:30 AM AST
Equipment: Visual + Binoculars, 10x42  IS
S&T Chart Reference: 14, 15, A
After pointing g out Aldebaran and the Hyades to Brianne, I showed her the Pleaides. We could very easily see this cluster. She had seen it before but hadn't known what it was.

Minor Planet: (7) Iris
Clusters: Melotte 20 (α Perseii Cluster, Collinder 39), Hyades
Messier Objects: M45 (Pleaides)

Location: Home
Date: 2017-10-28
Time: 7:45 PM & 10:00 PM AST
Equipment: Binoculars, 10x30 IS & 15x70
Transparency: Good (3)
Seeing: Good (3)
Temperature: 10º C

No wind. Clear skies. Waxing Crescent Moon.  Jerry and I were in the backyard observing; the primary reason for this session for me was to observe the Moon with my telescope - Explore the Moon (Telescope) - October 28, 2017. I was also able to complete IWLOP 092 - Clavius.

(7) Iris
Time: 7:58 PM & 9:40 PM ADT
Instrument: Visual + Binoculars
Having found (7) Iris the night before (thanks to Dave Chapman), I was able to show Jerry where to find it. Aries was high above our house so was able to show him how to locate the minor planet using κ Aries. The relative distances cited last night were no longer true; it appeared that the distance between κ and (7) Iris had increased. 

     

Melotte 20 (α Perseii Cluster, Collinder 39)
Time: not recorded
Instrument: Visual + Binoculars
S&T Chart Reference: 2, 1
Perseus was above the house across the street. The star Mirfak was easily identified but required binoculars to see the stars of the open cluster due to light pollution from the street lights.

Taurus & the Hyades
Time: not recorded
Instrument: Visual + Binoculars
S&T Chart Reference: 14, 15, A
Used my binoculars to look at Aldebaran. Also attempted to see the double star at σ Tau and the triple at δ Tau - no success. However, the Hyades open cluster was glorious!

M45 (Pleaides)
Time: not recorded
Instrument: Visual + Binoculars
S&T Chart Reference: 14, 15, A
First viewed the Pleaides visually that were easily found after seeing the Hyades. The used the binoculars to look closer at the "7 Sisters".

IWLOP #092 - Clavius

IWLOP #092 - Clavius

Exceptionally large crater seen at its best near the time of First Quarter and Last Quarter Moon. It is also visible in binoculars. Used some of the viewing time this evening for Explore the Moon (Telescope).

Location: 58.4 S 14.4 W    Origin: Impact     Size: 225 km     Rukl: 72, 73     Type: Complex Crater (CC)

Objects: Clavius, Rutherford, Porter, Clavius C, D, J, N (on crater floor), Clavius K, L, M (on/near the rim)

Location: Home
Date: 2017-10-28
Time: 8:10 PM ADT
Equipment: 10” Meade SCT
Eyepiece: Tele Vue 40mm Plössl
Magnification: x63
Seeing: Very Good (4) 
Transparency: Very Good (4)

No wind. 10° C.

Moon Phase: Waxing Gibbous (59.7% illuminated)
Moonrise: 3:05 PM ADT, Sunset: 6:16 PM ADT
Moonset: 1:15 AM ADT (Oct 29)

R1: Located Clavius next to Blancanus on the terminator. 
R2: Noted 4 craters in a unique half-circle of progressively smaller craters. Craters D, C, N and J on the crater floor began at Rutherford and ended near crater L.

C1: Found the overlapping crater Porter in the NE and the overlapping crater Rutherford in the SE. Craters C, D, J, N were identified on the crater floor; craters K, L, M were on or near the rim. 

NOTE: On June 19, 2021, we had our Grandson for an overnight. I had the 10" Meade SCT set up and we looked at the Moon with a 9.7 mm eyepiece (x258 magnification). What was really cool was that he was looking at the mares shown on the S&T Field Map of the Moon and was trying to locate them naked eye. One thing I showed him was Clavius that was on the terminator. We could see a black floor, one exterior wall that was very well lit, and the top rims of two craters (perhaps C & D) looked like a pair of eyes peering out into the darkness.

No wind. Clear skies. First Quarter Moon. Jeff Donaldson had a neighbourhood outreach session and a few of the RASC Halifax Centre members were there with binoculars and telescopes to assist.

Dave Chapman showed Gillian and I how to locate Minor Planet (7) Iris in the constellation Aries. We had to put Hamal, Sheraton and Mesartim in our FOV, then focus on Hamal to find κ, then continue along that line to (7) Iris. It was almost equidistant, i.e., the distance between α and κ was equal to that of κ to (7) Iris. Very exciting! Thanks, Dave!

Planet: Saturn
Messier Objects:
M8 (Lagoon Nebula), M20, M45 (Pleiades)
Identified, Not Observed: Cassiopeia, Summer Triangle, Ursa Major, Ursa Minor

Location: Sky Circle, Kejimkujik National Park

Temperature: 24º C - 14º C
Clear skies, no clouds. Little if any breeze. Some humidity but good seeing and transparency.

Aquila
Time: 9:05 PM ADT
S&T Chart Reference: 64, 65, 66
Instrument: Visual
Located Altair then was able to identify all the remaining bright stars in the constellation.

Saturn
Time: 9:30 PM ADT
Instrument: Visual + Binoculars
Located the planet naked eye as it was quite bright in the south sky. It was in Ophiuchus between 45 Phi and Sabik. The best way to explain where it was located was to draw an imaginary line from Alnasi (the spout of the Teapot) to Sabik; Saturn was located just below that line a little less than half the distance from Sabik.
   
M8 (Lagoon Nebula)
Time: 10:16 PM ADT
S&T Chart Reference: 67, 69, I
Instrument: Visual + Binoculars 
The Milky Way was a bit soft during the part of the evening as well - haze/ humidity? The Teapot was partially set behind the tree line but I could make out Kaus Borealis and Nunki. Using Kaus Borealis, I went westerly along the tree line and found the Lagoon Nebula. The line of 5 bright stars with the surrounding oval-shaped nebulosity was easily identified. 

M20 (Trifid Nebula)
Time: 10:16 PM ADT
S&T Chart Reference: 67, 69, I
Instrument: Visual + Binoculars
Using Kaus Borealis, I went westerly along the tree line and found M8 then 
looked a bit higher in the sky to find the Trifid. Saw three bright stars and numerous dimmer ones in a circular grey patch.

Perseus + α Perseii Cluster
Time: 11:05 PM ADT
S&T Chart Reference: 2, 13
Instrument: Visual + Binoculars
Again, Perseus rose high in the sky above the tree line. I focused my attention on Mirfak and the α Perseii Cluster. Tried to determine if there was a difference in Algol's brightness from the night before.
M45 (Pleiades)
Time: 11:20 PM ADT
S&T Chart Reference: 14, 15, A
Instrument: Visual + Binoculars
As Taurus rose higher, M45 became visible as well. Always a joy to see this bright jewel. Initially viewed visually, then with binoculars where the star field filled the FOV. 
Cygnus + Omicron (ο) Cygni
Time: 11:50 PM ADT
S&T Chart Reference: 62, 73, H
Instrument: Binoculars
Jerry and Dave assisted in finding it by explaining where it should be located. No trouble finding ο2 and ο1, the latter with 2 stars. My challenge was finding the third star. After 20 minutes or so on my back on the bench in the Sky Circle just staring at this part of the sky - SUCCESS! Finally saw all 3 stars of ο1 in Cygnus! My frustrations are at an end! Should attempt to find it again with my 15x70 binoculars and perhaps the telescope at home.
   

Hyades / Melotte 25
Time: 1:05 AM ADT
S&T Chart Reference: 15
Instrument: Visual + Binoculars
Noticed the open cluster below/near the Pleaides. Used the binoculars to look at the cluster, Aldebaran and briefly at the other stars in Taurus. Numerous stars were located around the "V" formation of Taurus. It was a very open cluster.

Instrument: Visual + Binoculars (10x30 IS)
Transparency: Very Good (4)
Seeing: Very Good (4)
Very clear skies over the eastern horizon. Cool breeze. Clouds appeared later. I had forgotten my binoculars back at the campsite so this morning was a naked eye only session.

Zodiacal Light
Time: 5:10 AM - 5:40 AM ADT
Instrument: Visual
The white triangular shape rose out of the eastern skyline above the trees. The rising Venus (1º - 2º above the tree line horizon) served almost as a centre point to the base. The 'point' went up quite far past Leo, to Libra and the Beehive (M44) and perhaps even lighting up an edge of Gemini.

Sirius (in Canis Major)
Time: 5:10 AM ADT
Instrument: Visual
S&T Chart Reference: 27
Sirius was easily identified as part of the Winter Circle asterism. I didn't look for the other stars in Canis Major at this time.

Orion, M42 (Orion Nebula/NGC 1976) + NGC 1981 + M43 (NGC 1982)

Time: 5:25 AM ADT
Instrument: Visual + Binoculars
S&T Chart Reference: 14, 16, B
This observations was in concert with observing the Winter Circcle and the Zodiacal Light. Betelgeuse, Bellatrix, Rigel, and Saiph. Also made out the upper 2 stars in the belt and their fuzziness/nebulosity. Upon closer examination of the sword, I could identify NGC 1981 (just above M42), M42, & M43. M42 and M443 were seen as a single unit a little bigger than NGC 1981 above it. No single stars were evidenced at this sighting.

Winter Circle + Winter Triangle
Time: 5:23 AM + 5:34 AM ADT
Instrument: Visual
Forgot my binoculars!! This was the morning that Jerry and I watched Venus rise above the horizon with the appearance of the Zodiacal Light (ZL).

To my surprise, the first thing seen in the early morning was the Winter Circle. Capella and Aldebaran were the highest stars of the Circle. Orion's stars in the belt and sword were so easily seen naked eye. Some of Auriga was also seen.

My second surprise was Procyon and Gomeisha were easily seen - the one constellation that to this date had escaped me seeing both stars. Sirius, Pollux and Castor were also identified. NOTE: The stars Procyon, Betelgeuse and Sirius comprise the Winter Triangle.

At the later time, the Hyades/Melotte 25 was seen naked eye. 

 
Canis Minor
Time: 5:23 AM ADT
Instrument: Visual
S&T Chart Reference: 25
Procyon was located as one of the primary stars in the Winter Circle. I then saw Gomeisa (β). Because of the tilt of the Circle at this time of year, Gomeisa was almost directly above Procyon and as easily seen naked yet. Finally saw Gomeisa! 
 
Castor & Pollux (in Gemini)
Time: 5:23 AM ADT
Instrument: Visual
S&T Chart Reference: 23, 25
Winter circle was very high in the sky so Castor and Pollux were very easily found. Didn't look for the other stars in this constellation.
Auriga
Time: 5:30 AM ADT
Instrument: Visual
S&T Chart Reference: 12
Recognized Capella first as part of the Winter Circle and Winter Triangle high in the sky. Then noticed the characteristic pentagon of the constellation. DIdn't see nor search for δ Auriga.
Leo
Time: 5:30 AM ADT
Instrument: Visual
S&T Chart Reference: 25
Very readily identified the backwards question mark just above the tree horizon - Regulus, η, Algieba (γ), Adhafera and Rasalas. Didn't search for κ or λ. Leo's hind end (Denebola) was below the treeline but Zooms and Chertan were just peeking above the trees. I looked for but could not find ι or σ.

Taurus & Hyades/Melotte 25
Time: 5:35 AM ADT
Instrument: Visual
S&T Chart Reference: 14, 15, A
I did see Aldebaran, ζ and Elnath naked eye. Buried in the Hyades were ε and γ. Very high in the sky (~ 55º - 60º) and very visible as part of the Winter Circle and Triangle.

Venus
Time: 5:35 AM ADT
Instrument: Visual
Venus rose above the tree line, very bright! We watched as it rose higher in the morning sky, until it was about 1º - 2º above the trees. Couldn't miss it!

Meteor
Time: 5:35 AM ADT
Instrument: Visual
Began near Aldebaran and the Hyades then continued Easterly towards Venus.

Teapot (in Sagittarius)
Time: 9:15 PM ADT
Instrument: Visual
S&T Chart Reference: 66, 67, 68, 69, I
The Teapot was seen above the trees of the Sky Circle. All 8 stars were located.

Identified Vega visually then used binoculars to view ε1, ε2, δ1 and δ2. Sheliak (β), ζ and γ were found naked eye.

NGC 869/884
Time: 8:48 PM ADT
S&T Chart Reference: 1, 2, 13
Instrument: Binoculars (10x30 IS)
I drew an imaginary line between Navi and Ruchbah in Cassiopeia then continued along that line a little over once that distance to find this double cluster. Both appeared as grey fuzzies with a few bright stars in their centres.

Cygnus
Time: 10:30 PM - 10:38 PM ADT
S&T Chart Reference: 62, 73, H
Instrument: Kejimkujik's telescope
I tried to locate 16 Cygni with binoculars but was unsuccessful. Chris Young used the Park's telescope to locate this double star and we discovered two in the same FOV - 16 Cygni and θ Cygni. The latter pair were located at 6:30 o'clock to 16 Cygni and were much fainter.

 

Triangulum
Time: 10:45 PM ADT
S&T Chart Reference: 2, 4
Instrument: Visual 
Found the 3 stars below Andremda very easily naked eye and attempted to view them with binoculars. Success. 
Dave Chapman then directed me to M33.

M33 / Pinwheel Galaxy
Time: 10:45 PM ADT
S&T Chart Reference: 2, 3, 4, 5
Instrument: Binoculars 
Holding my eyepiece so that α Triangulum was at 6 o'clock, I moved the binoculars slightly upwards to find M33. It appeared as a grey oval fuzzy; I didn't discern any bright stars in it with this small magnification.

M13 (Hercules Cluster)
Time: 10:50 PM ADT
S&T Chart Reference: 52, 54
Instrument: Visual + Binoculars (10x30 IS)
Gillian Webster requested assistance to find M13. I first showed her on a star chart where the Keystone was located relative tot he head of Draco which she knew. Using binoculars, we located M13.

Capricornus
Time: 10:55 PM ADT
S&T Chart Reference: 66, 68, 77
Instrument: Visual + Binoculars (10x30 IS)
Gillian asked for assistance in locating "Orion's Underpants", aka Capricornus. She easily saw it after I described it as a clown smile. I pointed out Algeidi (α), Dabih (β) and noted they were both double stars. Using binoculars, we were both able to see the double stars in each.

Neptune
Time: 11:05 PM ADT
Instrument: Binoculars (10x30 IS)
Saw Fomalhaut in Pisces Austrinus and heard someone saw Neptune was in Aquarius (just above where I was looking). Looked for the planet and found it near Hydor. Bright blue, very clear limb borders compared to the neighbouring stars.
   

M45 (Pleiades)
Time: 11:10 PM ADT
S&T Chart Reference: 14, 15, A
Instrument: Visual + Binoculars (10x30 IS)
As Taurus rose higher in the sky, M45 became visible as well. Always a joy to see this bright jewel, initially naked eye and then have the star field fill my binocular FOV. Glorious!

Perseus + α Persii Cluster
Time: 11:20 PM ADT
S&T Chart Reference: 2, 13
Instrument: Visual + Binoculars (10x30 IS)
Perseus rose high above the tree line and was very easily seen naked eye. All stars, including those in his 'arms' had previously eluded me but were now easily seen. Amazing to see! Using my binoculars, I looked more closely at Mirfak and its surrounding α Persii Cluster and at Algol. I had hoped to begin to track Algol's variability, especially now that it was at a minimum.

Explore the Moon (Telescope) - September 17, 2018

While working on this telescope version, I am also observing and drawing for the RASC IWLOP. At this point in the lunar cycle, I am observing items seen before, but I am now looking at them in a new light. Also took some time to look at Mars and Saturn.

Lunar Phase: Waxing Gibbous (60.0%)
Q-day: +1

Moonrise: 3:12 PM                   
Sunrise: 6:56 AM          Sunset: 7:22 PM

Location: Home
Date: 2017-09-17
Time: 7:20 PM – 10:30 PM
Equipment 1: 6” Dobsonian with 10 mm & 25 mm eyepieces
Magnification: x120 & x48
Equipment 2: 10” Meade SCT with 10 mm eyepiece and x2 Barlow
Magnification: x530
Transparency: not recorded
Seeing: not recorded
Temperature: 24° C @ 8:14 PM; 16° C @ 10 PM
SQM: 17.58 @ 8:14 PM; 19.11 @ 10 PM

No clouds and only a very light breeze that gained a bit of speed before the evening concluded. Had 2 telescopes for use: 6” Dobsonian and 10” Meade SCT.

Around 9:15 PM or so, I used the 10” Meade SCT with the x2 Barlow. Thankfully this telescope tracked after I used the handheld device to find craters that looked interesting.

Wondered whether Nonius was created by an oblique hit versus a direct hit.

I found a “row” comprising Arzachel, Alphonsus, Ptolemaeus and Herschel. What a neat grouping. Because I turned the star diagonal to the other side of the scope, it made my image not only mirror-reversed but also upside-down – go figure! Also found a new crater – Spörer.

In Arzachel, there was a well-lit, off-centre peak and two bands of low mountains. Also saw Rimae Arzachel.

Alphonsus had a ridge going SE to NW that showed a little bit of shadow.

The west side of Ptolemaeus looked craggy, perhaps ridged. A high peak in the east (adjacent to Ammonius) was clearly visible.

Herschel had a conical shadow towards the NE and looked ridged down/up from that shadow.

Sinus: Lunicus

Mountains & Related Formations: Mons Blanc, Montes Alpes, Promontorium Agassiz, Promontorium Deville, Rimae Arzachel, Vallis Alpes

Craters: Alphonsus, Arzachel, Cassini, Herschel, Ptolemaeus

Craters not in the ETU Telescope Version: Alpetragius, Aristillus (+ Aristillus A, B, C, D), Arzachel A, Calippus, Regiomontanus, Spörer, Theaetetus, Thebit, Thebit A. Walter and Nonius were viewed with the Dobsonian at x120 magnification.

Occultation: Moon-Aldebaran
Constellations: Corona Borealis, Cygnus, Delphinus, Draco, Scorpius
Asterism: Teapot
Stars
:
Aldebaran, Omicron Cygni

Satellites: (2)

Location: Site 15, Kejimkujik National Park
Date: 2017-09-12

Instrument: Visual + Binoculars (10x30 IS)
Transparency: Good (3)
Seeing: Good (3)
Temperature: 16º C - 10º C
This was the second day and night hubby and I were with Dave and Christine in the back country at our first Big Muise Island Star Party. The day was beautifully clear and warm, another great day to lay in the hammock and peruse the Observer's Handbook chapters I hadn't read yet. 
In the evening, there were clear skies overhead with a light breeze - and our first sighting of the Northern Lights from Kejimkujik National Park. 

Occultation: Moon and Aldebaran (in Taurus)
Time: 10:00 AM - 11:15 AM
Instrument: Visual
The sketch and photo of the occultation is recorded in Lunar Session - September 12, 2017. 

Aurora Borealis
Time: 8:10 PM
Instrument: Visual
Dave noticed an unusual brightness on the N-NE horizon that we thought perhaps was light pollution. However, when the brightness changed depth and shape, Jerry took a time lapse and confirmed it was indeed an aurora due to a solar flare.

Teapot + Scorpius
Time: 8:20 PM
Instrument: Visual
As we sat on the beach just past sunset, we watched as the stars of the Teapot in Sagittarius and those of Scorpius became visible in the south sky and provided guidance as to where the Milky Way would appear. Both were well above the horizon at this time of night. All 5 stars of the Teapot were easily located and identified. Antares showed as red in the sky and 3 stars in the scorpion's arc to its west were also visible. 

Satellite (LAGE052)
Time: 9:28 PM ADT

Instrument: Binoculars
Was looking for Corona Borealis ν1 and ν2 when a satellite came into my FOV near M13. Followed it through Ophiuchus and lost it in Sagittarius.
Satellite (ORBCOMM FMI[+])
Time: 9:50 PM ADT

Instrument: Binoculars
Looking for the Coathanger when it came into my view near Altair and travelled down Aquila to λ Aquila where it disappeared.

Delphinus
Time: 9:56 PM ADT
Instrument: Binoculars
S&T Chart Reference: 64
All 5 stars in the constellations were seen with binoculars.

M11 (Wild Duck Cluster)
Time: 10:02 PM ADT
Instrument: Binoculars
S&T Chart Reference: 67
Looked for the semi-circle of stars on the eastern border of the Milky Way above the Teapot. Used my binocular to easily find this small very bright cluster.

Corona Borealis - ν1 & ν2
Time: 10:12 PM ADT
Instrument: Binoculars
S&T Chart Reference: 53, 55
Using my S&T Pocket Sky Atlas, I determined it would be easier to locate ν1 and ν2 using the Keystone of Hercules and especially ζ Hercules. I visually formed a triangle using M13, ζ Hercules and where I thought ν1 and ν2  were located.  With just a little bit of readjustment in the search field, I did locate them. 

   

 

Draco
Time: 10:44 PM ADT
Instrument: Binoculars
S&T Chart Reference: 41, 42, 51, 52, 61
Looked for Draco's head and quickly identified γ and β; they fit into one FOV (almost) in my binoculars. I then moved the FOV 3 times that distance through star hopping and found them.

Cygnus & Omicron (ο) Cygnus
Time: 10:52 PM ADT
Instrument: Binoculars
S&T Chart Reference: 62, 73, H
I asked Dave for some assistance in finding some of the double and triple stars. I though I had found ο1 but that was not what I had found on August 5, 2017.

With his assistance, I did confirm I could see ο2, ο1-A, ο1-D but ο1-C escaped me. Dave then showed it to me in his telescope. There was ο1-C at 2 o'clock to ο1-A. Very happy at finding it!

Attempted to find 16 Cygnus but with such a rich star field and my dry eyes watering, I left it for another night.

Observation 1:

Sunspots

Location: Home
Date: 2017-09-08
Time: 4:05 PM - 4:13 PM ADT
Instrument: Binoculars (10x30 IS) with solar filters
Temperature: 23º C

Clear skies with occasional clouds, light wind. Three areas of activity were seen.

1- Near the equator had what appeared to be two spots - one circular and the other oblong with a slight curve.
2- At about 5 o'clock to this and appeared to have 3 segments - two near circular whereas the third was oblong and curved.
3- This area was very small and circular in the upper left quadrant.

NOTE: A photo in spaceweeather.com showed AR2677 and AR 2678. Not sure which of these two was seen.

   

Observation 2:

Constellations: Boötes
Planet: Uranus
Stars: Alkalurops (μ1 & μ2), HD135631, HR5673
Messier Objects: M23 (NGC 6494), M45 (Pleiades)
Moon: Waning Gibbous (92.1%)
Located, Not Observed: M8, M20, M21

Location: Wharf Road in East Noel, NS

Time: 9:40 PM - 11:00 PM ADT
Instrument: Visual + Binoculars (10x30 IS)
Transparency: Good (3)
Seeing: Good (3)
Temperature: 16º C - 14º C
Very light breeze. Clear skies. Light pollution in the low horizon across the bay. The Moon also washed out some of the stars. There were clouds travelling over the Moon that did provide some "darkness" and allowed for viewing.

Uranus
Time: not recorded
Instrument: Visual + Binoculars (10x30 IS)
Noticed a bright spot at about 10 o'clock to the Moon and a good distance away from it. Binoculars showed a blue, non-blinking object. SkySafariPro confirmed it was Uranus in Pisces.
   

M23 / NGC 6494
Time: 9:46 PM ADT
Instrument: Visual + Binoculars (10x30 IS)
S&T Chart Reference: 67, I

For details, refer to Messier Catalogue - M023 (NGC 6494) - September 8, 2017

   

Boötes
Time: 10:38 PM ADT
Instrument: Visual + Binoculars (10x30 IS)
S&T Chart Reference: 42, 44, 53, 55

Boötes was in the opposite side of the sky from the Moon. I found Arcturus then located δ Boötes and Neckar (β). Thought I visually could see the bright location of the double, but turned out it was actually HD135631 and HR5673 very close together in a vertical line.

I then adjusted where I should be looking - a little further away from the imaginary line between α and β and closer to the δ end of the line. Success!

   

M45 (Pleiades)
Time: 10:38 PM ADT
Instrument: Visual + Binoculars (10x30 IS)
S&T Chart Reference: 14, 15, A

Even though the Moon was quite bright, the main stars could still be seen - Asterope, Sterope, Tyageta, Electra, Maia, Merope, Alcyone, Pleione and Atlas. The star field and nebulosity behind and around them was not visible with the binoculars.

I was determined to find this cluster this evening. 

Looking at the star clouds, it appeared to be twice as far from the Teapot's spout as were M20 and M21. I located them easily then continued to what I thought was M23. I drew the sketch of what I saw then confirmed in a resource that the drawn star pattern was indeed M23. Success! It looked like there were thousands of stars in the open cluster to give it a hazy appearance behind the brighter stars.

General Session - September 2-8 , 2017 [(2166) Florence]

Asteroid: (2166) Florence

(2166) Florence is a 10.1 magnitude, 2.7-mile wide asteroid that orbits Earth every 2 - 4 years on average. Its distance is 1.8 AU and orbits between Earth and Mars. It is named in honor of Florence Nightingale (1820-1910), the founder of modern nursing. This 2017 encounter is the closest by this asteroid since 1890 and the closest it will ever be until after 2500. 

Location: Home
Date: 2017-09-02/08
Time: various times each evening
Equipment: Binoculars, 10x30  IS + Meade 200XL with Canon D800
S&T Chart Reference: 62

Transparency: Good (3)
Seeing: Good (3)

From September 3 to September 8, I followed the asteroid as it passed through the skies above our home. The asteroid passed through several constellations - Delphinus, Vulpecula, Cygnus and Cepheus - in its trek past our planet. It was interesting to see the "speed" at which it travelled day to day let alone on any given evening. Fascinating. It first caught my attention as it was approaching Cygnus.

September 4-5, 2017
Time: 9:00 PM - 12:40 AM
High haze, 17º C, no wind. Used binoculars to try to find the asteroid. I found Cygnus 39 and Cygnus 41 but couldn't see the asteroid. Jerry then set up the telescope and camera and took a series of photos. It was then that after viewing the photos and comparing to star charts that the location of the asteroids was found. I then followed it through the star field for several hours and sketched its path.

General Session - September 2, 2017 (Sunspots)

Sunspots

Location: Home
Date: 2017-09-02
Time: 6:15 PM - 7:45 PM ADT
Instrument: Binoculars, 10x30 IS with ND5 filters + 8" Meade LX200 with solar filter & 15 mm, 25 mm, 40 mm eyepieces
Temperature: 12º C

Partly cloudy becoming clear. Light breeze.

Observation 1:
Time: 6:25 PM
Instrument: 8" Meade LX200

There were 9 separate areas of activity, from very large to very small. 

(A) in upper left quadrant: One small black area with 2 even smaller areas adjacent to it.

(B) in lower right quadrant almost on the centre line: 6 areas varying in size. The largest had a large perimeter of activity with 4-5 large areas that were black in appearance. The lowest sunspot and the one immediately below the large one were similar in structure whereas the other 3 had no visible perimeter around the area of activity. The limb definition was variable, indicating the heat radiation from the surface.

   

Observation 2:
Time: 6:55 PM
Instrument: Binoculars

Saw 4 spots in the upper left quadrant. The smaller ones seen in the telescope couldn't be found in binoculars.

The one spot in the lower right quadrant didn't show the very tiny 2 areas of activity as seen in the telescope.

   

Observation 3:
Time: 7:05 PM
Instrument: 8" Meade LX200 with solar filter and 25 mm & 15 mm eyepieces

Using the 25 mm eyepiece, caught 7 areas of activity in the FOV. Three of these areas had a grey area in which there was 1 to 5 dark spots of activity. The largest was located just off centre and contained 4 areas of activity varying in size.

The 15 mm eyepiece more clearly showed there were 4 areas of activity; however, some of those areas could have been a combined large and small area.

NOTE:
The sketch shows the Moon, Antares and Saturn forming a triangle. However, in SkySafariPro on the same date and time shows the three of them in a different arrangement - Antares and the Moon forming the base and Saturn creating the shallow peak just above the midpoint. I cannot account for the difference.

Instrument: Binoculars
The Teapot readily located visually despite the Moon. Using binoculars, followed the line up from Kaus Australis through the middle of the spout to find M8. No chance of finding it visually given its proximity to the Moon. The characteristic line of 
stars crossing the nebulosity was seen.

 

NGC 869 / 884 (Double Cluster)
Time: 8:54 PM EDT
S&T Chart Reference: 1, 2, 13
Instrument: Visual + Binoculars
Used the line of stars from Mirfak to α Perseus up to ν Persei to locate the NGCs in the same FOV. They were in very close proximity and looked like diffuse grey areas around bright centres.

M31 (Andromeda Galaxy)
Time: 8:54 PM EDT
S&T Chart Reference: 3, 72
Instrument: Visual + Binoculars
With the Square of Pegasus and Andromeda high in the sky it was very easy to locate galaxy. Used both pairs of binoculars to view this galaxy Still wowed by the additional size and brightness of this galaxy in the larger magnification.

Perseus & M34 (α Persei Cluster / Mellotte 20)
Time: 8:54 PM + 9:20 PM + 10:07 PM EDT + one other unrecorded time 
S&T Chart Reference: 2, 13
Instrument: Visual + Binoculars

8:54 PM: Initially came across this messier object quite by accident when I was using my binoculars to scan the skies between Perseus and Andromeda. I came across a roundish fuzzy object that almost better seen with averted vision.
9:25 PM: Mirfak and α Persei Cluster (M34) were located higher above Cadillac Mountain. Located η, γ, τ, ι, β, ε and ρ.
10:07 PM: Algol and Atik were found when looking at Auriga.
I viewed it at one other time. I was very pleased - this meant I was truly "seeing" it!

  

Capricornus
Time: 9:01 PM EDT
S&T Chart Reference: 66, 68, 77
Instrument: Visual + Binoculars
Capricornus easily seen in the night sky despite being near the time of a Quarter Moon. I used the binoculars to view α1 and α2. At 9:28 PM, ψ Capricornus was at least 25º above the ocean horizon.

Satellite
Time: 9:09 PM EDT
Instrument: Binoculars
Followed it travelling from Altair along the length of Aquila into Sputum. Lost track of it after it passed M11.

Meteor
Time: 9:35 PM EDT
(Visual) Travelled from Polaris to Dubhe in Ursa Major.

Cepheus
Time: 9:40 PM EDT
S&T Chart Reference: 71, 73

Instrument: Visual
Errai, Alderamin (α), Alphirk (β), ι, δ, ζ and μ could easily be identified. Amazed that all could be seen but being on the opposite side of the night sky from the Quarter Moon. Not as bright as Cassiopeia, but close.

 

Delphinus
Time: 9:56 PM EDT
S&T Chart Reference: 64
Instrument: Binoculars
The 5 stars in Delphinus were easily found below Cygnus.

Sagitta
Time: 9:56 PM EDT
S&T Chart Reference: 64
Instrument: Binoculars
All 4 stars in Sagitta were easily found below Albireo and above Altair.

Triangulum
Time: 10:06 PM EDT
S&T Chart Reference: 2, 4
Instrument: Visual + Binoculars
Looked for Andromeda and Pegasus. Found the 3 stars below Andromeda naked eye. Then used binoculars to view β and γ; didn't look for δ Triangulum or 7 Triangulum.

Auriga
Time: 10:07 PM EDT + 10:52 PM EDT
S&T Chart Reference: 12
Instrument: Visual + Binoculars
Capella was noticed about 1º-2º just above the horizon on the crest of the Overlook. At the later time, I could identify Capella (α), Elnath (β), ι Auriga and Menkalinan. Only θ couldn't be seen.

Kemble's Cascade
Time: 10:07 PM EDT
S&T Chart Reference: 11, 13
Instrument: Binoculars 
Cassiopeia was readily located. Went 1 FOV from the constellation and found the bright stars of the Cascade that needed in the hockey stick formation.

M11 (Wild Duck Cluster)
Time: 10:17 PM EDT
S&T Chart Reference: 65, 67
Instrument: Visual + Binoculars
The Moon had almost set making theMilky Way appear brighter in the sky. Found the semi-circle of stars nearby and identified lambda Aquilae with naked eye and guessed as to the location of M11. Found it very easily with 10x30 IS binoculars - the backwards golf club beside the fuzzy M11 golf ball. When viewed with the 15x70, M11 changed shape slightly from round to a sort of rectangle with a hint of central bright stars. Quite a different look for this Messier object!

Coathanger / Collinder 399 / Brocchi's Cluster
Time: 10:20 PM EDT
S&T Chart Reference: 65

Instrument: Visual + Binoculars
After identifying the stars in Cygnus, I went below Albireo and located the 10 stars of the Coathanger with binoculars.

Cygnus
Time: 10:20 PM EDT
S&T Chart Reference: 62, 73, H
Instrument: Visual + Binoculars 
Deneb easily located as were Sadr, Albireo, δ and ε. Albireo appeared bluish in the binoculars.

Meteor
Time: 10:25 PM EDT
(Visual) Travelled from Scutum to the Teapot.

Ophiuchus
Time: 10:25 PM EDT
S&T Chart Reference: 54, 56, 67
(Visual) With naked eye, I identified the triangle formed by Rasalhague (α), Cebelrai (β) and κ Ophiuchus. From there, I looked down towards the horizon to find Sabik (η), ζ, ξ, ν and Yed. I did not look through binoculars to separate Yed Prior from Yed Posterior. Still amazed at how large this is. Didn't attempt to look for the arms/outer cape - this was a mistake given how clear the sky was at this time.

 

M45 (Pleaides)
Time: 10:34 PM EDT
S&T Chart Reference: 14, 15, A
Instrument: Visual + Binoculars
The Pleaides finally showed up above the tree line in e-NE. The 5 brightest stars and numerous others were seen through the binoculars and with naked eyes could see the open star cluster  almost rectangular in shape. Love this cluster for its brightness and ease of finding in the night sky.

Taurus & the Hyades Star Cluster
Time: 10:42 PM EDT
S&T Chart Reference: 14, 15, A
Instrument: Visual
Located Capella earlier in the evening then saw another bright star appear above the crest of the mountain in the E-NE later in the evening. Using SkySafariPro, I identified Aldebaran, Elnath, epsilon and gamma. Didn't look for lambda, nu, xi, zeta or 10 after finding the Hyades open cluster as they were below the mountain's crest.

This was my first attempt at identifying other stars in Taurus besides Aldebaran.

   

Pisces Austrinus
Time: 11:48 PM EDT
S&T Chart Reference: 76, 77, 78, 79
Instrument: Visual
Surprised to see this constellation relatively high above the horizon (compared to home) and adjacent to Capricornus. Could identify all 9 stars visually. Talk about exciting! With the Moon having set 
earlier it was so easy to see this constellation above the ocean's horizon. Saw Fomaulhaut (α) first then identified the other stars visually (using SkySafariPro as an assist). Didn't use binoculars to see the double stars of γ and μ (if in fact they could be seen).

Similar sky conditions as the night before at this site. It started out partly cloudy in the N and NW but cleared up.

Capricornus
Time: 9:25 PM EDT
S&T Chart Reference: 66, 68, 77
I could faintly see the 7 stars of this constellation naked eye. I used the 10x30 binoculars to view Deneb Algeidi, α Cap and β Cap.

Cassiopeia
Time: 9:27 PM EDT
S&T Chart Reference: 1, 3, 72
There were some clouds earlier but they cleared out. Consequently, all 5 stars of the constellation could be seen above the cliff.

Satellite
Time: 9:27 PM EDT
(10x30 Binocular) Caught sight of it above Altair then it crossed the corner of γ Delphinus before disappearing from view.

Ursa Major
Time: 9:29 PM EDT
S&T Chart Reference: 31, 32, 33, 43, F
All 7 stars readily seen in the sky. Used my 10x30 binoculars to locate and view the pair Mizar and Alcor in the handle.

Ursa Minor

S&T Chart Reference: 52, 54
The Keystone was almost directly above and could be seen visually. 

Corona Borealis
Time: not recorded
S&T Chart Reference: 53, 55
All 7 stars of the Corona were readily found west of Ursa Major. I used the curve of the Corona to locate M13 visually.

M13 (Hercules Cluster) 
Time: not recorded
S&T Chart Reference: 52, 54
I was able to locate M13 visually between η Hercules and ζ Hercules then used both pairs of binoculars to obtain a better view. 

Teapot
Time: not recorded
S&T Chart Reference: 66, 67, 68, 69, I
The Teapot's star were all visible at the beginning of this session. By 10 PM, Kaus Borealis, Kaus Media, Almasa and Kaus Australis had disappeared behind the trees.

M8 (Lagoon Nebula) 
Time: not recorded
S&T Chart Reference: 67, 69, I
Having found the Teapot, I again guessed the location of this nebula and was successful.

M20 (Trifid Nebula) 
Time: not recorded
S&T Chart Reference:67, 69, I
This evening I used both binoculars. Much brighter in the 15x70 but couldn't discern the 3 segments of the nebula in any way.

M22 (Globular Cluster) 
Time: not recorded
S&T Chart Reference: 67, 69, I
Kaus Borealis couldn't be seen but guessed where it was located to find M22. Note: I cold see all 4 stars in the Teapot handle.

M11 (Wild Duck Cluster) 
Time: not recorded
S&T Chart Reference: 67
I looked up in the Milky Way for an upside-down golf club with a fuzzy golf ball beside the head of the club. Found it below lambda Aquila. Used the 10x30  binoculars first then the 15x70. The latter showed a bigger and brighter fuzzy round object.

Sagitta & Delphinus
Time: not recorded
S&T Chart Reference: 64
Despite the haze and light pollution, the 4 stars in this very small constellation Sagitta were located below Albireo in Cygnus. Not very high magnitude stars but they could still be seen.

Not too far away, the 5 stars of Delphinus could easily be seen visually and they appeared brighter than the evening before. A slight twinkling was noted.

M31 (Andromeda Galaxy) 
Time: not recorded
S&T Chart Reference:
I located this using Cassiopeia and used both pairs of binoculars to obtain a better view. WOW to the larger view of the 15x70! The centre of the oval-shaped galaxy was so much brighter.

Square of Pegasus (in Pegasus)
Time: 10:00 PM EDT
S&T Chart Reference: 74, 75
Instrument: Visual
Just before leaving the beach, 3 of the 4 stars in the Square (Scheat, Algenib and Alpheratz) were visible above the cliffs across the river from us.

Coathanger /Collinder 399 / Brocchi's Cluster
Time: 10:25 PM EDT
S&T Chart Reference: 65
Instrument: Visual + Binoculars
Could not locate Albireo earlier in this session so decided to use Altair as the start point. Success! All 10 stars easily found with the binoculars. Showed this to Steve as well.

Messier Objects

M8 (Lagoon Nebula)
Time: not recorded
S&T Chart Reference: 67, 69, I
Instrument: Visual + Binoculars
The hazy skies and the tree line it made for difficult to find the spout of the Teapot; however, knowing where the lid was located,  I was able to find the nebula. The line of stars plus the grey fuzzy area around and mostly above the line were easily seen in the binoculars.

M13 (Hercules Cluster)
Time: not recorded
S&T Chart Reference: 67, 69, I
Instrument: Visual + Binoculars
I had found the Keystone earlier in this session. Locating it again, I looked 1/3 off the way from η Hercules to ζ Hercules to find the small, grey, round cluster with the binoculars.

 

M31 (open cluster)
Time: not recorded
S&T Chart Reference: 3, 72
Instrument: Visual + Binoculars
Used Cassiopeia to locate Andromeda as we couldn't see the Square of Pegasus. It was a grey fuzzy of indeterminant shape and better seen with averted vision.

 

M20 (Trifid Nebula)
Time: not recorded
S&T Chart Reference: 67, 69, I
Instrument: Binoculars
Having found M8, it was easy to look in the upper portion of my binocular FOV to see this nebula. A central bright area but not  able to discern individual stars.

M21 (open cluster)
Time: not recorded
S&T Chart Reference: 67, 69, I
Instrument: Binoculars
M21 was found in the same FOV as M20 but a little up and to the left in the FOV.

No wind or clouds. There was a wide open field not far from our campsite with a huge view of the sky. What clarity of viewing! The only down side to this campground was the trailer in the adjacent campsite that ran its generator all night.

Coathanger / Collinder 399 / Brocchi's Cluster
Time: not recorded
S&T Chart Reference: 65
I used Altair in Cygnus to locate the 10 stars of this upside-down coat hanger, a dear friend in the night skies. It feels like coming home after a long trip.
Ursa Major + Polaris
Time: not recorded
S&T Chart Reference: 31, 32, 33, 43, F
In the open field, we could make out all 7 stars naked eye but used binoculars to see the double stars Mizar and Alcor. Could also locate Polaris using the pointer stars of UMa but it was very faint to the naked eye.

Teapot (in Sagittarius)
Time: 9:13 PM EDT
S&T Chart Reference: 66, 67, 68, 69, I
The Teapot could be seen naked eye; however, part of it was hidden by trees.

Cassiopeia

Cassiopeia was so clear! We could readily locate the 7 bright stars in this constellation.

M31 (Andromeda Galaxy)
Time: not recorded
S&T Chart Reference: 3, 72
I used Cassiopeia to locate M31 no problem. With binoculars, it appeared as a dark, oval fuzzy with the brighter centre.

Lyra

We could readily locate the 5 bright stars in this constellation that led us to the Keystone of Hercules.

Boötes 
Time: 10:08 PM EDT
S&T Chart Reference: 42, 44, 53, 55
I could readily locate Arcturus throughout this observing session.  At this time, I found all the stars in Boötes, including the "arm extension" via naked eye. Used my binoculars to better view λ, κ and θ along with Asella Secunda (ι).

Keystone of Hercules (in Hercules)
Time: 9:55 PM EDT
S&T Chart Reference: 52, 54
We used Corona Borealis to locate the Keystone. The 4 stars in the Keystone were observed but we did not look for the other stars in the constellation. Found the faint fuzzy M13 using the binoculars.

M13 (Hercules Cluster)
To find this, I looked 1/3 off the way from η Hercules to ζ Hercules naked eye, then found the same location using Corona Borealis to confirm. I then found the small, grey, round cluster with the binoculars.

Meteors
Time: 9:47 PM EDT
(Visual) Travelled from the Keystone down towards the horizon.

Time: 10:16 PM EDT
(Visual) Crossed from above Altair to η and ζ in the wing tip.

 

 

Satellite
Time: 10:06 PM EDT
(Binoculars) Caught sight of it in Pegasus and it travelled towards Cassiopeia. Lost sight of it in Cassiopeia when a plane flew into my FOV.

Delphinus
Time: 10:10 PM EDT
S&T Chart Reference: 64
Once we quickly located Altair in Cygnus, we could find all 5 stars in this small constellation. They were quite clear in these skies!

Capricornus
Time: 10:20 PM EDT
S&T Chart Reference: 66, 68, 77
We saw 2 stars in a horizontal line that through SkySafari pro were identified as Capricornus α1 and α2
. How wonderful! "Orion's Underpants" were found! Using my binoculars, I was able to see the double stars in Algedi (α) and Dabih (β). From this I was able to locate naked eye: ω, θ, ε and Deneb Algiedi way over towards the north. First sighting of Capricorn on this trip! How exciting!

M22 (Globular Cluster)
Time: 10:28 PM EDT
S&T Chart Reference: 67, 69, I
Couldn't see all of the Teapot but could see Kaus Borealis well enough to find the faint grey fuzzy M22.

M6 (Butterfly Cluster)
Time: not recorded
S&T Chart Reference: 56, 58, 67, 69, J
Just happened to notice several bright stars in V-shaped opening in the treeline. SkySafariPro confirmed it was the Butterfly Cluster.

M72 
Time: 10:30 PM EDT
S&T Chart Reference: 66, 77
When looking at Capricornus, I found a faint grey fuzzy at a parallel declination or maybe just a bit above alpha Capricornii. Come to find out later in my star maps that it was M72. New discovery!!

Time: 9:00 PM - 10:40 PM EDT
Instrument: Visual
Transparency: Very Good (4)
Seeing: Very Good (4)
Temperature: 18º C - 16º C

No wind. Scattered clouds. Due to the threat of rain overnight and the distance between the car and our walk-in site, we left our cameras and binoculars in the car. The evening started out cloudy as could be expected given the weather report but it provide an extended period of clear skies as the night progressed. The night sky at the rocky beach front to our site varied from beautifully clear to partial cloud cover. Jerry and I sat on a large rock to take in the darkness and the amazing sky above us.

Ursa Major (UMa)
Time: 9:14 PM
S&T Chart Reference: 31, 32, 33, 43, F
When the skies were clear, all 75 stars of UMa were readily identified and we could consequently locate Polaris.

Ursa Minor (UMi)
Time: 9:14 PM
S&T Chart Reference: 41, 51
Located 6 of the 7 stars of UMi. Could not find η.

Meteor
Time: 9:14 PM
Travelled from Dubhe in UMa to Draco before disappearing.

Andromeda (M31)  & Cassiopeia
Time: 9:35 PM
S&T Chart Reference, Cassiopeia: 1, 3, 72
All 5 stars of Cassiopeia were readily identified.

With the help of SkySafariPro, was able to locate Andromeda and its bright stars Alpheratz (α And) and Mirach (β And) above the distant tree line. From there we could locate Almach (γ And), μ And and υ And to draw the lines for her "legs". Didn't search out the stars for her "arms" but rather used Mirach and μ to locate M31 (Andromeda Galaxy).


Draco
Time: 9:45 PM CST
S&T Chart Reference: 41, 42, 51, 52, 61
Draco had been shown to me at SCO and I had identified the head in the past. This was the first time identifying the other stars in the constellation as it wound around Ursa Major (UMa) and Ursa Minor (UMi).

Viewing Draco naked eye, we used SkySafariPro to wend our way around UMa and UMi. We started with the 4 stars comprising the head then identified Altais (δ), ε and φ - never saw χ. We then located θ and Edasich (ι), followed by Thuban (α). Using the app, we were then able to fill in the spaces between φ and θ (except ω). Once these were all found, it was so exciting to "see" Draco as it curled around the two Bears!

Cygnus
Time: 9:55 PM
S&T Chart Reference: 62, 73, H
We located Deneb and could easily find Sadr, Glenah, Al Fawaris and Albireo

 

 

 

Delphinus
Time: 10:00 PM 
S&T Chart Reference: 64
The stars of Delphinus could be identified naked eye slightly above Altair.

Corona Borealis
Time: 10:03 PM 
S&T Chart Reference: 53, 55
All 7 stars in the Corona were readily identified. they were used to locate the Keystone of Hercules and potentially M13 (Hercules Cluster).

Hercules, Keystone of Hercules & M13
Time: 10:04 PM 
S&T Chart Reference: 52, 54
Corona Borealis led us to Hercules.  We identified π, η, ε and ζ. We were not sure if we could see M13 a very faint fuzzy between η and ζ.

We also attempted to locate the stars in the 4 extensions from the Keystone and did find several. Refer to the sketch.

Note: "X" on the sketch indicates they were not located (except M13).

Light breeze and no clouds as we camped beside the Mississippi River - but they didn't tell us about the numerous trains passing on the tracks on the other side of the river at all hours.

Ursa Major
Time: not recorded
Instrument: Visual + Binoculars 
S&T Chart Reference: 31, 32, 33, 43, F
Easily located all 7 stars in the constellation visually. With the binoculars, saw the Mizar-Alcor pairing.

Ursa Minor
Time: 9:00 PM
Instrument: Visual 
S&T Chart Reference: 64
Using the pointer stars of Ursa Major, easily locate all 7 stars in the constellation except η. For me, this has always been a difficult to see.

Lyra
Time: 9:15 PM
Instrument: Binoculars
S&T Chart Reference: 63
I located Vega, ζ, ε1 and ε2, δ1 and δ2, β and γ. 

Perseus + α Persii Cluster
Time: 9:33 PM
Instrument: Visual + Binoculars
S&T Chart Reference: 2, 13
Able to see Mirfak, γ Perseus and δ Perseus. There were numerous stars seen around Mirfak, much like an open cluster; very bright stars extended towards δ. I had found the α Persia cluster!

NGC 869/884
Time: 9:33 PM
Instrument: Visual + Binoculars 
S&T Chart Reference: 1, 2, 13
Used naked eye and binoculars. Located Perseus then noticed the 2 clusters above Miram, NGC 884 was a more diffuse grey fuzzy - numerous stars in the cluster with perhaps lower magnitudes. NGC 869 had 3 bright points in an otherwise grey fuzzy area. Both were easily seen in the same binocular FOV.
NOTE: There were 2 stars between Miram and the NGCs that I did not identify

Conjunction Saturn-Spica
Time: 9:10 PM EDT
Instrument: Visual + Binoculars 
Located Spica visually; couldn't see the other stars of the constellation due to light pollution. Using the binoculars, I viewed Saturn that was within 10º of Spica. Saturn was located slightly higher in declination than Spica.

General Session - August 21, 2017 (Solar Eclipse)

Solar Eclipse! Totally Awesome!

(© Photo Montage of the Eclipse by Jerry Black)
 
Location: Lingley, Wyoming
Date: 2017-08-21
Time: 10:30 AM - 1: 15 PM
Equipment: Visual + Binoculars 10x30 IS
Transparency: not recorded
Seeing: not recorded

How far will one travel to see a solar eclipse for the first time in their life? Does 4,393 km (2,739.7 miles) - one way - sound a bit far? Having just experienced my first solar eclipse, I can unequivocally say NO!

The planning of this trip began a year ago when Paul Gray had announced at a RASC Halifax Centre meeting that he had the perfect spot to view the eclipse - from the KOA in Grand Island, Nebraska. KOA reservations made last fall - check. Plan remainder of the 2.5-week trip to and from this exciting event - check. So, let's now focus on the experience in Nebraska. I remembered Roy’s cautionary note about experiencing the eclipse versus taking pictures. Consequently, I dictated notes to my phone so that my eyes didn’t have to leave what I was seeing for more than a split second.

The evening before the eclipse, there was a gathering of astronomers to determine the plan of attack for the next day based on weather reports and Jay Anderson's advice. Once back at our campsite, we decided we would travel further west from Grand Island, probably as far as Wyoming to ensure a clear sky. We left at 6:30 AM CST after a small breakfast, drove through dense fog across part of Nebraska before arriving at our sunny clear blue skies location on Hwy 85 north of Lingley, Wyoming at 10:30 AM Mountain Savings Time (MST). Interesting to note is that at one point when we turned towards Wyoming on Hwy 26, every other car (of which there were hundreds in the adjacent two lanes of traffic) headed north on Hwy 385 to Alliance, one of the sites suggested the evening before. We were grateful we were going another way, but perhaps we went further than needed.

We drove through Lingley (population 468, elevation 1,272 m) and parked on the side of the highway next to a farmer's field on the crest of a small hill. We arrived two minutes before first contact and had a phenomenal 360° view. Jerry quickly set up for his time lapse photography whereas I opened my binocular bag and witnessed first contact with filter-covered binoculars at 10:32 AM MST.

With the solar filters in place, the sunspots were seen. They would perfectly provide the reference points by which to observe the rate at which the moon covered the sun. Four sunspots were located in the upper right quadrant of the sun, starting near the centre and going from lower left to upper right. A fourth was noted between the first and second but it was very weak and small and not as clearly defined.  Two more sunspots were also noted at about 7 o'clock on the southwestern limb. 

 I watched as each sunspot was hit by the limb of the Moon:

  • 10:48 AM - first sunspot hit by limb of Moon
  • second sunspot hit by the limb of the Moon probably around 10:50 - 10:52 given its proximity to the first sunspot
  • 10:56 AM - third sun spot hit by limb of Moon
  • 11:01 AM - fourth sunspot covered by limb of Moon

 At 11:05 AM, I noticed the sun not quite as bright as it was earlier. The sky was getting just a bit darker and the colours of the landscape were subdued, not as vibrant as they were when the sun was full.

At 11:20 AM, I offered my binoculars to the family of 6 next to us. Each in turn had a chance to see in a much larger view how the moon was covering the sun and to see the sunspots in the southwest limb. So much fun watching their reactions, from the parents to the 6-7 year old. Also shared with a couple standing across the highway, and with a father and daughter who pulled beside us just a few minutes before totality. 

At 11:40 AM, the temperature noticeably cooled, enough so that a sweater was required. Also noted that we were now being serenaded by chirping crickets. It was at this point I had total interest in what was happening around me versus recording the time frame. I did not note when the lower two sunspots were covered by the Moon nor the time and length of totality. I tried to remember Roy Bishop's description of what to expect but failed to do so in the excitement of what I was seeing.

I turned my back to the sun at one point and watched as darkness quickly approached. I likened it to being a teeny weeny little creature watching the great cape of Darth Vader billowing out as it approached and eliminating any hope of escape. I held my breath totally, enraptured as I watched it come across the field and overtake me.

What I saw next had me turning a complete 360°, and probably more than once in a couple of different directions in my attempt to decided which way I should look. A beautiful rainbow of colour appeared on the darkened horizon when the shadow overtook us. This was the one and only time I took a photo during the eclipse - a panoramic view of about 120° to 130°. Too many cars in the way to take the full 360. You can see the centre of the shadow as it rapidly travels eastward.

Totality was reached! Darkness was upon us. Regulus, Jupiter and Venus were seen but I didn't think to look closer for other planets (Mars and Mercury) and stars as suggested in articles previously read. The back orb covering the sun contrasted with the elongated translucent streams of the white solar corona that reached out into the now darkened sky. I stood there transfixed and could only think, "Oh, wow! This is really cool!"

Thanks to Jerry reminding me that filters were not required at this point, I held the filter-free binoculars once more to my eyes to view the prominences at various locations around the moon's limb. Their fire engine red-pink colours were indescribably beautiful. I handed my binoculars to the daughter and father adjacent to us for them to see them as well. The corona wasn't perfectly circular; longer spikes at 12, 2 and almost 7 o'clock were visible. The corona was spectacular; the extent from its source was astonishing.

  

Once the binoculars were back in my hands and up to my eyes, Bailey's Beads appeared. Light came through the Moon's crater valleys and seemingly bent around the Moon's surface to produce a reddish glow on its surfaces, especially on the Moon's limb at 12, 1 and near 3 o'clock.  

Then it happened! The "diamond"! It started as a small glimmer on the Moon's limb then shone blindingly just above the Moon's equator! Another wow. So cool! Gave me goose bumps.

According to the reference book materials, totality at our site was 2 minutes 11 seconds. It was such a short time. This wasn't long enough to truly absorb what was happening. Could a replay be granted?

It was now 11:53 AM. My wits are back (if they ever are) and I can once more record the events. Filtered binoculars and eclipse glasses were in use once more, and the air was still cool enough (for me) to require a jacket. The sun's light affected the colours around us, much like a spot light bleaches colours out; the dark greens of the field and nearby grasses had become a grey-green, shadows perhaps not as distinct. The crickets were still chirping. 

The moon now began to reveal the sunspots it had earlier hid from our view:

  • 12:13 PM - the first sunspot. Cars were now streaming slowly on the highway behind us; they had obviously given up once the moon had begun to reveal the sun.
  • 12:17 PM - the weaker of the 4 sunspots was now visible.
  • 12:23 PM - the third sunspot was revealed. Cars were now bumper-to-bumper heading towards Lingley.
  • 12:27 PM - the fourth sunspot was unveiled. It was also now warm enough to remove my sweater. Colours have returned to their true colour and the sound of the chirping crickets is reduced from what they were earlier during totality.
  • 1:08 PM - the first of the two sunspots in the southwest quadrant were uncovered by the moon.

At 1:14 pm, the eclipse was complete. The Moon lost contact with the southwest quadrant of the sun. Time to pack up and head back to the KOA. I now had another check mark on my Explore the Universe certificate submission! A short video of our experience can be seen at https://www.youtube.com/watch?v=k7HWur4Twp8.

End Note: Although it only took us 5 hours to arrive at Lingley from the KOA, the return trip took 11 hours. The distance between our eclipse location and the turnoff onto Interstate 80 should have taken only one hour but took 5 hours. Our heads hit our respective pillows at 1:15 AM CST, still whirring with the excitement of the day. Our trip home to Nova Scotia begins in 5 hours...

1- Went for a morning walk and saw the crescent high in the sky. Saw it visually only as we left for the walk.

2- When we returned to Mom's apartment, I used my binoculars to see a very brightly lit crescent. To the East, there was a small section that was partially visible before fading in the morning sky. There was very little if any breeze. A high hazy cloud allowed viewing of the Moon but couldn't make out details on the lit terminator. Could make out dark Grimaldi.

First noticed the Full Moon at 9:50 PM when on my way home. At home, there were wispy clouds travelling past the Moon until 11:02 PM when the sky opened for a clear view. Many features could be easily identified even though fully lit. Clouds returned and there was no opportunity to clearly view the moon again until 11:58 PM; the skies provided an opening until 12:10 AM when I called it quits.

Ejecta Rays:
- Tycho and its expansive rays over much of the Moon

General Session - August 6, 2017

Besides looking at Saturn, I spent the earlier part of this evening exploring the Moon towards achieving Explore the Moon (Telescope) - August 6, 2017.

Constellations: Boötes, Cassiopeia, Corona Borealis, Lyra, Ursa Major
Planet: Saturn
Asterism: Summer Triangle / DAVe
Meteor: (1)

Location: Home
Date: 2017-08-06
Time: 9:06 PM - 11:15 PM
Instrument: Visual + Binocular 10x30 IS
Transparency: Poor - Fair (1-2)
Seeing: Poor - Fair (1-2)
Temperature: 19º C - 18º C

Fairly clear skies but slight haze and 99.3% Waxing Gibbous Moon affected seeing and transparency. Heavy dew in the early evening disappeared around 10 PM.

Ursa Major
Time: 9:15 PM + 11:12 PM
Instrument: Visual
S&T Chart Reference: 31, 32, 33, 43, F

I was able to see all 7 stars quite readily at the first observation. However, all 7 stars appeared dimmer at the later observation, their brightness muted by the atmospheric conditioned and/or the Moon.

Summer Triangle / DAVe
Time: 9:39 PM
Instrument: Visual + Binocular 10x30 IS

A little breeze began at 9:06 PM but it disappeared around 10:00 PM. Located Deneb and Vega at 9:39 PM and Altair at 9:52 PM. Only some of the strs in each constellation could be seen so didn't spend much time looking - except around Deneb for Cygnus 16 and ο1. 

Boötes
Time: 9:36 PM
Instrument: Visual
Due to the Waxing Gibbous Moon (99.3%) it was challenging to find stars. I did locate Arcturus visually and quickly located what I refer to as the Boötes extension above the Dipper - λ, κ and θ.

Saturn
Time: 9:36 PM
Instrument: Visual + Binocular 10x30 IS

Saturn was easy to pick out in the sky just above our tree line. However, I did not see any adjacent stars.

Corona Borealis
Time: 10:09 PM
Instrument: Visual + Binocular 10x30 IS
S&T Chart Reference: 53, 55

Alpheca was very bright when it was first seen. With my back to the Moon, I visually could see Alpheca plus β, θ and γ. With my binoculars, I could also find ε; however, ι could not be identified in the slightly hazy skies.

Meteor
Time: 11:09 PM
Instrument: Visual 

A bright white flash lasting ~ 1 second "downwards" in my perspective. Meteor flash went from NW to NE through Cepheus.

Lyra
Time: not recorded
Instrument: Visual
S&T Chart Reference: 63

Located Vega and visually locate Lyra ε and Lyra ζ. I didn't use binoculars to see the remaining stars.

Cassiopeia
Time: not recorded
Instrument: Visual 
S&T Chart Reference: 1, 3, 72

Walked to the deck side of the house and the shadow of the house next door to escape from the Moon and street ligh respectively. Cassiopeia was fairly visible from this location. All 5 stars could be seen but they were dimmed/muted by the atmosphere and/or the Moon. Given its dimness and that of UMa, I gave up for the night at 11:15 PM.

A few clouds with a slight wind. Could see atmospheric turbulence at the terminus and limb edges.

9:06 PM: The Moon finally rose over the houses across the street.

~ 10:15 PM: Moon was high enough it could be seen with the telescope. The rays of Kepler and Tycho were easily seen. Surface was completely bleached out; no real features were seen except for a few at the terminator. Attempted to draw Kepler’s rays. The features adjacent to Kepler on the Moon’s rim captured my attention so sketched them next.

Windy. Cloud cover increased during the session. Good viewing until the clouds completely covered the Moon. Sucker holes thereafter. The sucker holes allowed for brief viewing of the Moon. One view (from Sinus Iridum to the Moon’s north limb) was only seen for about 30 seconds; this allowed for a rather hurried sketch.

Schikard was near the terminus. Its westernrim had shadowing and there was a crater at its southern end.


Sirsalis and Sirsalis A: the left side was more shaded than the right in the FOV and ‘darker’ than the surrounding terrain.

Identified Cavalerius, Hevelius and Lohrmann north of Grimaldi. Luna 9 landing NE of Cavalerius on Oceanus Procellarum.

 

 

 

Identified Foucault and Harpalus in Mare Frigoris north of the Montes Jura. Also identified Babbage north of Frigoris with a crater on its floor (centred?).  The latter was the largest of the 3 and was near the limb.

Constellations: Boötes, Cygnus, Lyra, Ursa Major
Asterism: Summer Triangle
Sunspot:  (1)
Stars: Cygni 30, Cygni 31A

Instrument: Visual + Binocular 10x30 IS
Transparency: Fair-Good (2-3)
Seeing: Fair-Good (2-3)
Temperature: 16º C

Mostly cloudy skies that provided the occasional sucker hole for observing. Also windy.

Sunspot
Time: 4:45 PM
Instrument: Binoculars 10/30 IS

A sunspot (AR2670) was found using solar filters (ND5) on the binocular lenses. 

Lyra
Time: 9:28 PM
Instrument: Visual + 10x30 IS Binoculars
S&T Chart Reference: 63

I was able to visually identify Vega. 

I then used my binoculars and in 1 FOV could easily see Vega, ε1, ε2, ζ1 and ζ2; δ1 and δ2 had to wait until the next tie there was a clear sky.

Boötes
Time: 9:35 PM
Instrument: Visual + 10x30 IS Binoculars
S&T Chart Reference: 42, 44, 53, 55

Located Arcturus visually and attempted to identify the kite shape of the constellation. Could only identify ζ, η, ρ and Arcturus. The others were difficult to find naked eye.

Having found the Big Dipper in Ursa Major (UMa)a few moments earlier, I pointed my binoculars up from UMa t find what I refer to as the "Boötes extension" - θ, κ, ι, and λ. ι was easily seen but I had identified it earlier as HR 5360 - not sure which it was.

Summer Triangle
Time: 9:28 PM + 9:40 PM
Instrument: Visual 

Depending on the size of the sucker holes, all or a portion of the Triangle was visible.

Ursa Major
Time: not recorded
Instrument: Visual
S&T Chart Reference: 31, 32, 33, 43, F

During one of the instances of a clear sky, I was easily able to see all 7 stars of the Big Dipper visually and located Mizar-Alcor visually as well. I used my binoculars to view Mizar-Alcor. Clouds negated the ability to locate Polaris.

Cygnus

I was looking for Cygnus 16 but couldn't find it. However, I did find a double star that unfortunately I didn't realize it was Omicron Cygni. Looking closer, I had Cygni 30 on the upper left and Cygni 31A in the lower right of my FOV. I found them by locating Deneb and then δ Cygni. From the imaginary line between them, I looked a little above it and a little less than half way from Deneb. Success!

I will look on another evening when he Moon and clouds don't limit my "stare" time.

Clear skies with only a few clouds. Clouds started to move in from the N-NE later in the session.

Ursa Major
Time: 9:45 PM + 11:00 PM
Instrument: Visual 
S&T Chart Reference: 31, 32, 33, 43, F

The partly cloudy skies cleared by 8:30 PM so that all the stars in Ursa Major were visible at the earlier observing time. By 11 PM, the clouds covered the constellation completely.

Saturn
Time: 8:30 PM + 11:25 PM
Instrument: Visual + Binocular 10x30 IS

Saturn was located visually earlier in this session. At the later time, I thought I had caught 2 moons in my sight. However, came to realize the brighter 'star' was ξ Ophiuchus and the fainter one was HR 6472. No moons of Saturn were seen. See the conjunction sketch below.

Satellite
Time: 11:25 PM
Instrument: Binocular 10x30 IS

The satellite entered my FOV when looking at Sabik in Ophiuchus. It passed between Sabik and 58 Oph just north of Saturn before disappearing.Ursa Minor

Explore the Moon (Telescope) - August 3, 2017

Part of this session was spent looking at other celestial bodies - General Session - August 3, 2017. There also just happened to be a conjunction of Moon-Saturn-Antares.

Lunar Phase: Waxing Gibbous (87.7%)
Q-Day: +3

Moonset: 2:29 AM          Moonrise: 5:37 PM
Sunrise: 6:03 AM            Sunset: 8:38 PM

Location: Home
Date: 2017-08-03
Time: 8:15 PM – 11:40 PM
Temperature: 20° C - 17° C
Equipment: 10” Meade SCT, 10 mm + 30 mm eyepiece; Binoculars 10x30 IS
Magnification: x250 + x83; x10
Transparency: not recorded
Seeing: not recorded

Mostly clear skies that clouded over much of the sky as the night went on until ~ 11:15 PM when there was just a clear patch around the Moon. Most of the evening was spent on the ETM (telescope version) list. Found tonight were several craters, mountains, and valleys. Very excited about the ones found!

 

I was surprised that having missed one night of observing due to cloud cover that so many items could be seen tonight. I started with 30 mm eyepiece to sketch areas that caught my interest: Gassendi, Mare Iridium (north shore) and Sinus Iridum.

  • Vallis Apennine: Found this tonight and at the Quarter Moon.
  • Montes Alpes: Was only able to see part of this range previously but can see it all this evening.
  • Confirmed I could re-find the following:
    1. Mountains: Apennine, Spitzbergen, Tenerife
    2. Craters: Archimedes, Aristillus, Autolychus, Clavius, Copernicus, Maginus, Plato, Timocharis, Tycho
  • NEW tonight:
    1. Maria: Humorum, Imbrium, Iridum, Oceanus Procellarum
    2. Mountains: Carpatus, Jura, Montes Recti (Straight Range), Riphaeus (sketched)
    3. Craters: Aristarchus, Bullialdus (large, raised centre), Gassendi (sketched), Kepler, Lansberg, Longomontanus (NE of Schiller), Reinhold, Schiller, Wilhelm (very little rim)
  • The Straight Wall (Rupes Recta) was missed before and certainly couldn’t be seen this evening either.
  • Crater Mersenius was just on the terminator tonight and couldn’t be verified.

10:44 PM

I switched to the 10 mm eyepiece. Between Maria Crisium and Tranquilitatis was a very brightly lit circular crater rim with 2 rays emanating from it. I asked Dave Chapman about this and he explained they were called “rays” (deposits of light-coloured material from impacts). One ray touched the mountain/mare edge of Tranquilitatis whereas the other went between the two maria and faded into the landscape. The field between this crater and Tranquilitatis is darker than the field between it and Crisium. It had many white-rimmed very small craters or raised cones.

NOTE: On March 21, 2021, I learned this fan-shaped area was Palus Somni with Proclus as the bright crater on its rim. The bright areas within were minor craters.

There were some areas seen that weren’t labelled on the RASC map provided:

  1. Palus Putredinus (Marsh of Decay): Looked this up. Area that stretched from the centre of Archimedes southeast to the edge of Mare Imbrium and the Apennines. Autolychus in the north. Apollo 15 landing site!
  2. Mare Insularum (Sea of Islands): Located in the Insularum basin south of Mare Imbrium. Bordered by the craters Copernicus on the east, Kepler in the west. Oceanus Procellarum joins the mare in the SW.
  3. Mare Cognitum (the Sea that has become known): Located in a basin that sits in the second ring of Oceanus Procellarum. The Montes Riphaeus are to the NW. Ranger 7 landed here.

Feeling better and more comfortable with identifying reverse images of the Moon. Almost makes sense now.

11:30 PM
I switched to binoculars to see what I could see. It was then that I noticed Saturn was near the Moon.

Explore the Moon (Telescope) - August 1, 2017

During this session, I also considered this a general session - General Session - August 1, 2017.

Lunar Phase: Waxing Gibbous (72.3%)
Q-Day: +2

Moonset: 1:17 AM          Moonrise: 3:47 PM
Sunrise: 6:01 AM           Sunset: 8:40 PM

Location: Home
Date: 2017-08-01

Temperature: 26° C - 23° C
Equipment: 10” Meade SCT, 30 mm eyepiece
Magnification: x83
Transparency: not recorded
Seeing: not recorded

Clear skies. My first attempt at viewing was at 7:34 PM but it was too bright. Went back out 1 hour later with better viewing of the features. After spending much time sketching, I then attempted to identify features required by the Explore the Moon (telescope version).

  1. Tenerife Mountains: Had to look these up online to determine what to look for, and to get a clearer identification as to where to look, i.e., SW of Plato in northern part of the Mare Imbrium. Found.
  2. Spitzbergen Mountains: Again, looked them up – a crater diameter to the N of Archimedes. The photo didn’t hurt.
  3. Straight Wall: Didn’t find this and suspect will have to wait to next Moon cycle to find it.

Although listed for the next day, I was able to see Mare Imbrium and Copernicus. North of Copernicus were 4 small craters that formed an upside-down and backwards “L”. Using a digital Moon Map, I was able to identify Timocharis, Lambert and Pytheas but was unable to identify the smallest of the four. It was just inside the mare adjacent to Monte Carpatus or just on its slope facing the mare.

   

Maria & Sinus:
Crisium, Imbrium, Nectaris, Nubium, Serenitatis, Sinus Medii, Tranquilitatis, Vaporum.

Montes:
Carpatus, Spitzbergen, Tenerife

Craters:
Archimedes, Aristillus, Autolychus, Clavius, Copernicus, Eratosthenes, Maginus, Plato, Timocharis, Tycho

Other Craters not on the List:

Temperature: 16º C - 14º C

Clear skies. No wind. First Quarter Moon in the sky.

Summer Triangle / DAVe
Time: 9:34 PM
Instrument: Binocular 10x30 IS
The 3 stars in the asterism "DAVe" were easily located - Altair, Deneb and Vega in Aquila, Cygnus and Lyra respectively. They were found despite the bight Moon of 1 day after the First Quarter.
Satellite
Time: 9:46 PM - 9:49 PM
Instrument: Binocular 10x30 IS
Entered my FOV at Mizar-Alcor then travelled through Draco to Deneb. I lost sight of it at 5ºN of Altair.

Boötes
Time: 9:50 PM
Instrument: Visual
S&T Chart Reference: 42, 44, 53, 55

Despite the Moon obliterating my view of numerous stars, the stars comprising the "kite" were found. Arcturus had been found earlier in the viewing session.

Satellite
Time: 10:10 PM - 10:12 PM
Instrument: Binocular 10x30 IS
This very small satellite flew into my FOV while viewing the Coathanger. I followed it past Deneb towards Ursa Minor but lost sight of it when I changed positions.

Coathanger / Collinder 399 / Brocchi's Cluster
Time: 10:10 PM - 10:15 PM
Instrument: Binocular 10x30 IS
S&T Chart Reference: 65

Located Albireo in Cygnus, then found the 10 stars of the Coathanger. A satellite came into my view while looking at this asterism.

Saturn
Time: 9:39 PM and 10:15 PM - 10:17 PM
Instrument: 8" Meade SCT, 9.7 mm eyepiece
Magnification: x187

Saturn was very visible just below Ophiuchus and above Scorpius (about 10 o'clock to Antares). The different scope meant the rings were seen differently and two of its moons were visible - Rhea and Dione.

Location: Home
Date: 2017-07-30
Time: 9:00 PM - 11:53 PM
Instrument: Visual + Binocular 10x30 IS + 10" Meade SCT (100 mm + 30 mm eyepieces)
Transparency: Good (3)
Seeing: Good (3)
Temperature: 19º C - 14º C

Clear skies. No wind; a small breeze mid-evening that was barely discernible. First Quarter Moon in the sky.

Saturn
Time: 9:15 PM
Instrument: Visual + 10" Meade SCT, 10 mm + 30 mm eyepiece
The planet was very bright in the night sky. Rings covered the bottom of the plant and I could just make out a broad band on the planet just above Saturn's equator. One of the Moons was quite distant (3-4 times the rings' diameter.

  

Ursa Major (UMa)
Time: 10:15 PM
Instrument: Visual + 10" Meade SCT with 30 mm eyepiece
S&T Chart Reference: 43, 32

All the stars were visible at 10:15 PM but it was 20 minutes later that Dubhe could be easily seen visually. Polaris could easily be found visually.

Using the telescope at 10:44 PM, I looked at Mizar and Alcor, Mizar being the brighter of the pair. 

Cassiopeia
Time: 10:35 PM
Instrument: Visual
S&T Chart Reference: 1, 3, 72

Had no problem identify the 5 bright stars in this constellation.

 

Satellite
Time: 10:46 PM
Instrument: Visual
Passed from Cygnus through the head of Draco, then disappeared.

Summer Triangle / DAVe
Time: not recorded
Instrument: Visual
Despite the Moon, I was able to locate Vega, Altair and Deneb, in that order as they became apparent in the darkening skies.

 M51 (Whirlpool Galaxy)
Time: 10:54 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 32, 43

Using the distance between Alkaid and Mizar, I looked below Alkaid just a little lesss than this distance and saw a faint, grey circular smudge. Not positive it was M51 but it was the only "smudge" in the vicinity. Next time look at the adjacent star patterns to ensure identification.

Cygnus
Time: 11:07 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 43, 32

The Moon obscured the dimmer stars visually. At this time, the constellation was overhead. The stars ζ, η and ι were not easily seen visually. Used Albireo as a way to locate the Coathanger.

Coathanger / Collinder 399 / Brocchi's Cluster
Time: 11:07 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 43, 32

Travelled down the stars of Cygnus to Albireo then found the Coathanger - all 10 stars were clearly identified.

 

Canes Venatici
Time: 11:11 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 43, 32

Decided to look for this constellation and one of the arms of Boötes because the sky in this direction was darker and not affected by the lights of Halifax.

Using my S&T Atlas, I found this constellation lay directly below Ursa Major's handle. Specifically, Cor Caroli (α)was directly below Alkaid; this was easily found visually and I also looked for Arcturus as another guide. With my binoculars, I was able to find Cor Caroli. Jubilation at also being able to find Chara (β) with binoculars! It wasn't until I looked on the internet and at my map more closely that I discovered α was a binary star. I will look more closely next time.

   

Boötes
Time: 11:15 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 42, 44, 53, 55

Saw most of the stars in Boötes except Seginus. Looking at the star Atlas made me want to look for an extension away from the "kite" that contained θ, κ and λ. I located Alkaid and looked one FOV above it and there it was. The 4 stars of the corner were very clear and were in 1 FOV of my binoculars. SkySafariPro helped me identify the names of the stars. I was thrilled to be able to find this group of stars using landmarks as guides.

   

Lyra
Time: 11:35 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 63

Searched for the Lyra stars in this constellation to confirm the two sets of double stars. Lyra ε1 and Lyra ε2 were easily found in binoculars. Following through Lyra ζ, I was able to locate the red and yellow Lyra δ1 and Lyra δ2 respectively. Vega, Lyra ζ, Lyra δ1 and Lyra δ2  were in one FOV and I was able to centre them in the middle of the FOV.

 

   

Delphinus
Time: 11:42 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 64

The 5 stars of Delphinus were visible but were considerably fainter due to the First Quarter Moon.

Equuleus
Time: 11:42 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 43, 32

I looked to Delphinus and after several second found α, δ, and γ Equ. It took a while to find ε with the binoculars. In examining γ Equ, I could see two stars there - γ Equi + 6 Equ. At ε Equ, I could make out 4 Equ and 3 Equ. I didn't take the time to note the colour differentiation (if any) or brightness, Next time?

   

Satellite
Time: 11:49 PM
Instrument: Binoculars 10x30 IS
Satellite crossed my FOV while looking at M31. It travelled from Andromeda to Perseus before disappearing.

Meteor
Time: 11:49 PM
Instrument: Visual
Travelled through Hercules towards Libra but disappeared before leaving Hercules.

Pegasus
Time: 11:50 PM
Instrument: Visual
S&T Chart Reference: 74, 75
Had to go to the deck side of the house to find Cassiopeia and the Square of Pegasus. There were limitations to seeing not only due to the Moon but also due to street lights if I walked too close to the front of the house.

M31 / Andromeda Galaxy
Time: 11:50 PM
Instrument: Binoculars
S&T Chart Reference: 3, 72
I used Cassiopeia and the Square of Pegasus to locate M31 - a grey oval smudge - with my binoculars.

Explore the Moon (Telescope) – July 30, 2017

The lunar journey begins! Besides the Moon observing, there was also time to look for other objects in our universe – constellations and their asterisms and special stars, Messier objects and even a couple of satellites that passed by - General Session - July 30, 2017.

Lunar Phase: First Quarter (53.2%)
Q-Day: 0

Moonrise: 10:47 AM
Sunrise: 5:32 AM         Sunset: 9:05 PM

Location: Home
Date: 2017-07-30

Temperature: 18° C
Equipment: 10” Meade SCT, 30 mm + 10 mm
Magnification: x83 + x250
Transparency: not recorded
Seeing: not recorded

This was my first time looking through our 10” Meade SCT and getting my brain wrapped around the mirror view. Without any go-to or other source of mechanical movement, Jerry and I had to manually move the scope to the desired position. We jokingly referred to this scope as the “push-to”.

There was disappointment in that some of the items listed at Q-day 0 could not be seen; they were beyond the dark portion of the terminator, such as Herschel, Ptolemaeus, Alphonsus and Arzachel. However, I was able to identify 2 items on the list for Q-Day -1:

  • Montes Haemus – the mountain range on the south border of the Mare Serenitatis.
  • Manilius – located on the border of the Montes Haemus.
  • Aristoteles
  • Eudoxus
  • Mare Serenitatis

Most of the 2 hours of this observing session was dedicated to sketching the Lunar X, first with 30 mm eyepiece and then the 10 mm. However, there was time to identify other lunar features.

Time: 9:47 PM + 9:57 PM
Instrument: Visual + Binoculars 10x30 IS
Jupiter was very bright in the sky. I was searching the sky for Arcturus. First sighting of Jupiter was just below Arcturus, then 10 minutes later it was at the same declination as Spica.

Lyra
Time: 9:38 PM - 11:20 PM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 63
An experiment this evening to see (literally) what time stars in a given constellation became visible - visually and with binoculars.
9:38 PM: Vega was very easily seen as were ε and ζ.  I went from Vega to ζ to δ and found the double stars at δ.
11:15 PM: With my binoculars, I was able to see that δ2 was red in colour whereas δ1 was yellow. I stared at them for 30 seconds to make sure the colours I saw were in fact red and yellow. 

Scorpius
Time: 9:40PM - 10:15 PM
Instrument: Visual
S&T Chart Reference: 56, 58, J
The second experiment of the evening. Wanted to see when the stars of Scorpius would become visible in the southern horizon (or at least when I noticed they became visible).
9:40 PM: Antares
9:48 PM: ν, Graffias
9:54 PM: π, ρ 
10:12 PM: The stars below Antares in the constellation were visible above the tree line. Perhaps θ or η were faint or below the trees.

Cassiopeia
Time: 9:48 PM
Instrument: Visual
S&T Chart Reference: 1, 3, 72
I was able to easily locate and identify all 5 stars of the brightest stars in this constellation.

Saturn
Time: 9:48 PM
Instrument: Visual
Saturn was adjacent to the Teapot in Ophiuchus between θ and Sabik. Did not make note of its moons.

Ursa Major
Time: 9:50 PM + 10:37 PM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 31, 32, 33, 43, F
I visually identified all the stars within Ursa Major, not just the Big Dipper asterism. I later used my binoculars to look at the optical double in the handle - Mizar and Alcor.

Satellite (ISS)
Time: 10:00 PM - 10:06 PM
Instrument: Visual
First sighting was near Spica and Jupiter. Path continued to arrive above Alkaid to about 15º above Cash (in Cassiopeia) to just above Alpheratz (in Pegasus) before disappearing.

Satellite
Time: 10:35 PM - 10:36 PM
Instrument: Binoculars 10x30 IS
Sighting was accidental. Looking at Antares with my binoculars when it entered my FOV. It disappeared near Spica.

M7 (Ptolemy's Cluster)
Time: 10:50 PM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 58, 67, 69, I
The Teapot was high for most of the night. I followed the line from Ascella to Kaus Australis, then followed the extension of that line out to M7 that was found a little more than one FOV from Kaus Australis. I used my binoculars to view the brilliant stars that could also be located visually.

 

M22
Time: 10:57 PM PM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 67, 69, I
Using my binoculars, I trained them onto Kaus Borealis after locating it visually. With that star in my lower right FOV and with a little movement towards the upper left I was able to find a little "Y" star formation and just past that was the small, grey, fuzzy M22.

M28
Time: 10:57 PM
Instrument: Visual + Binoculars 10x30 IS
Using Kaus Borealis visually and finding M22, I put the eyepiece back on the lid star in the lower left and M28 was readily seen as a round smudge. It had what appeared to be a brighter/denser centre. Couldn't discern any stars in the cluster with my binoculars.

Scutum
Time: not recorded
Instrument: Visual + Binoculars 
I again started with the naked eye to look for the semi-circle above the Teapot and then to look for the elongated diamond. delta, epsilon, beta and alpha were easily found but gamma took some effort. I looked for gamma at 11:00 PM and did find it. My disappointment was that I didn't see the double star.

   

M8 (Lagoon Nebula)
Time: 11:05 PM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 67, 69, I
Using my binocuIars, I followed the line out of the mid-spout and discovered the recognizable line of stars in M8. Almost comforting to find something I know and in a familiar location. 

M11 (Wild Duck Cluster)
Time: unknown
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 67
I looked for the semi-circle of stars above the Teapot. Using my binoculars, I easily located the 'golf club' and 'golf ball' (aka M11).

M20 (Trifid Nebula)
Time: unknown
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 67, 69, I
Once I found M8, M20 was easy to find within the same FOV. The grey smudge with the box of stars within were easily seen using binoculars.

M21
Time: unknown
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 67, 69, I
After finding M20 a few moments earlier, I went up a partial FOV at about 45º to M20 to see M21 very clearly in my binoculars.

Meteor
Time: 11:09 PM
Instrument: Visual
It ran parallel to 2º - 5º below the line from Ascella to Kaus Borealis in the Teapot.

Libra
Time: 11:29 PM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 46, 57
Libra was very low in the sky but I was able to see α Libra (Zubenelgenubi). The brightness of this star alerted me this constellation was now visible.
I put my binoculars up to this star and had a long look at it to discover this was a double star - α1 and α2. Alpha1 was a bright yellow star and about twice the size of its companion. Alpha2 was a bluish star, fainter and seemed to be twinkling at times. I didn't look for the other stars in this constellation.
Capricornus
Time: 11:56 PM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 66, 68, 77
I moved to the far end of the gravel pads next to the trees in the west. Given Scorpius and Sagittarius had moved towards the west, I hoped to locate this constellation - and I did. Most of the stars could be located except ζ and ε that were hidden by a tree. After finding the constellation visually, I used my binoculars to look at α Cap1 and α Cap2 (Algedi) and had no difficulty doing so.

NGC 7000 / North America Nebula
Time: 12:25 AM - 12:45 AM EDT
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 62, 73
Art Cole was at SCO tonight and pointed out NGC 7000. He pointed to Deneb in Cygnus and said it was just below it, that it looked like North America, including the Gulf of Mexico.

I used my binoculars and sat in the gravity chair in my attempt to find it. For the life of me, I couldn't find the dark Gulf to identify the nebula, even after 20 minutes of searching. However, maybe because of a strong desire to locate/see it, or because of my imagination, I thought I could faintly see it visually. Need another clear night to attempt again.

Kemble's Cascade
Time: 12:41 AM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 11, 13
Now that Cassiopeia was higher in the sky and away from the trees, I was easily able to visually determine where Kemble's Cascade was located and then to see it with my binoculars, including the hockey stick ending.

How to find Kemble's Cascade:
Place digit #1 (e.g., your left thumb) on Caph and digit #2 (e.g., your left baby finger) on Segin. Holding your fingers in that position and following the line/direction formed by Caph-Segin, move digit #1 on Caph to Segin so that digit #2 is away from Cassiopeia. The top of the Cascade should now be where your baby finger is located in Cameliopadardalis. Look for the hockey stick ending!

New Moon. No wind or cloud. 
Helped Jerry get set up for his astroimaging then sat and watched as the stars made their appearance in the night sky. New Moon today.

Saturn
Time: 9:50 PM
Instrument: Binoculars 
Saturn was located near the Teapot. Easily found due to its visual brightness. Using binoculars, I could determine it wasn't a "round" object but couldn't see the rings at this level of magnification.
Jupiter
Time: 9:55 PM
Instrument: Binoculars 
I was looking for Spica (which I did find) but also noted Jupiter was once more near Virgo.

Summer Triangle / DAVe
Time: 9:50 PM - 10:05 PM
Instrument: Visual
Three stars the asterism exposed themselves over a 10-minute period - Deneb, Altair, Vega.


Keystone of Hercule & M13 (Hercules Globular Cluster)
Time: 10:17 PM + 12:05 AM
Instrument: Visual + Binoculars
S&T Chart Ref: 52, 54

I viewed the Keystone of Hercules that appeared overhead. M13 could be seen naked eye between η Herculis and ζ Herculis.

I used the binoculars to confirm what I was seeing visually. I also viewed it again with binoculars after midnight when I was able to point out all 4 arms of Hercules to Jerry. I was amazed at how easy it was to find all the stars in the arms.

Corona Borealis
Time: 9:56 PM - 2:30 AM
Instrument: Binoculars 
S&T Chart Ref: 53, 55
I could easily identify all the stars in the Corona. Although the initial sighting was at 9:56 PM, it was seen numerous times throughout this observing session.    

Ursa Major
Time: 9:56 PM
Instrument: Binoculars 
S&T Chart Ref: 31, 32, 33, 43, F
Easily made out all 7 stars of the Dipper plus Polaris naked eye. No binoculars. 

    
Cassiopeia
Time: 10:12 PM + 12:00 midnight
Instrument: Binoculars 
S&T Chart Ref: 1, 3, 72
All 5 stars were readily seen naked eye. Attempted to use binoculars but the multitude of stars in my FOV confused me. When I easily found this constellation at midnight, I decided to try to find Kemble's Cascade.
Kemble's Cascade
Time: 10:00 PM + 12 midnight
Instrument: Binoculars
S&T Chart Ref: 11, 13
Could find all of Kemble's Cascade at 12 midnight but could not find it around 10 PM when looking at Cassiopeia. A beautiful tumbling of stars that ended in the hockey stick.

M4 (NGC 6121)
Time: 10:15 PM + 10:34 PM + 12:08 AM
Instrument: Binoculars 
S&T Chart Ref: 56, 58
Viewed Antares specifically at 10:15 PM and 10:34 PM naked eye. Used my binoculars to
locate M4 at 12:08 AM. Again, the grey fuzzy was better seen with averted vision - both
visually and with binoculars.
   

Meteor
Time: 10:30 PM
Instrument: Visual
Travelled from Cepheus towards Cygnus.

M7 (Ptolemy's Cluster, NGC 6475)
Time: 10:40 PM
Instrument: Binoculars 10x30 IS
S&T Chart Ref: 56, 67, 69, I
Teapot was high for most of this viewing session. I followed the line from Ascella to Kaus Australis then followed the extension of that line out the same distance to M7. The open cluster was very visible, the brighter stars forming a squarish ring within the nebulosity and had numerous less bright stars around them. Not as showy as the Pleiades - but close!

Scorpius
Time: 10:34 PM 
Instrument: Visual + Binoculars 
S&T Chart Ref: 56, 58, J
Scorpius was mostly above the tree tops but η, θ and ξ were below the treeline. I noticed the 'stinger' was quite bright so used my binoculars to look at the 2 stars - Shaula and Lesath. I wasn't disappointed. Both quite bright in a single FOV.
M69
Time: 10:43 PM
Instrument: Visual
S&T Chart Ref: 67, 69
Located Kaus Australis and the adjacent sides of the Teapot. Put Australis in my lower right FOV and looked towards Nunki but just above the Ascella-Australis line. Found it with averted vision. It was a dark grey small fuzzy object.

Cygnus
Time: 10:52 PM + 12:35 AM
Instrument: Visual + Binoculars 
S&T Chart Ref: 63, 73, H
Deneb had come out earlier in the evening; had to wait to visualize the stars in Cygnus to find Albireo, Sadr and η Cygni when the sky was darker and the Milky Way was just starting to show up. Could easily see the wing stars from ζ to ι. The blue-gold of the double star Albireo could be seen but seemed to "twinkle"; could not discern between the 2 stars with the binoculars. Saw Cygnus visually again in the early morning - quite evident in the Milky Way.
Coathanger / Collinder 399 / Brocchi's Cluster
Time: 10:52 PM
Instrument: Binoculars 
S&T Chart Ref: 65
Just put my binoculars to my eyes after locating Albireo and guesstimated where it might be located - et voilá! Just like an old friend. I love finding this asterism! All 10 stars were very clearly seen.

Delphinus
Time: 10:52 PM + 12:12 AM
Instrument: Visual
S&T Chart Ref: 64
Found Delphinus visually twice while looking for Sagitta. All 5 stars, although not exceedingly bright, could be seen above Aquila. Art Cole and I had a discussion about the two small constellations.

Satellite (ISS)
Time: 11:05 PM
Instrument: Visual + Binoculars 
Noticed a high speed bright light light going from Boötes towards the Square of Pegasus. Its speed was a little too fast for a plane and there were no red-green blinking lights. Binoculars confirmed it was not a plane. Art Cole confirmed it was the ISS. Very big! Very bright! VERY fast!

Satellite
Time: 11:20 PM
Instrument: Visual
Travelled from mid Boötes and disappeared before reaching Alkaid in UMa.

Satellite
Time: 12:07 PM
Instrument: Visual
Travelled from bottom of Ophiuchus across the top of the Teapot. Quite bright. Lost visual in the trees.

Sagitta
Time: 12:12 AM
Instrument: Visual
S&T Chart Ref: 64
Found the 4 stars of Sagitta above Altair. It formed a triangle with Delphinus and Aquila. The stars, like those in Delphinus were not very bright - had to look at the stars for a few seconds to out α and ß, whereas γ and δ were more readily found.

M31 (Andromeda Galaxy)
Time: 12:15 AM + 12:30 AM
Instrument: Visual + Binoculars 
S&T Chart Ref: 3, 72
Cassiopeia, the Square of Pegasus and Andromeda constellation were in an area of the sky high enough above the trees behind the Storage Room that M31 could be found - visually and with my binoculars. Visually, it was a faint fuzzy. With binoculars, it could be seen with direct vision but better viewed with averted. It was viewed twice in this session. Bright core and nebulous oblong quite large compared to the core.

Meteor
Time: 12:25 AM
Instrument: Visual
Travelled from Camelopardalis and disappeared at Kemble's Cascade.

Pegasus
Time: 12:30 AM
Instrument: Visual
S&T Chart Ref: 74, 75
Able to see all 4 stars in the Square of Pegasus (Alpheratz, Algenib, Mark, Scheat) and the nearby Andromeda. However, the legs were hidden by the trees.

Perseus
Time: 12:30 AM
Instrument: Visual
S&T Chart Ref: 2, 13
I saw what to my eyes was an arch of stars below Cassiopeia which led me to believe these were not stars in that constellation. I had drawn an imaginary line from τ to ι, then to κ, Algol and ρ. I then continued another arch through ο, Atik, and Menkib. Using SkySafariPro, I also discovered that it was Perseus! Knowing that, the only stars I couldn't find visually were γ, b, φ and θ.

Capella (in Auriga)
Time: 12:53 AM
Instrument: Visual 
S&T Chart Ref: 12
I found Capella just above the horizon while standing between the warming and storage sheds. It was very bright! I had to use SkySafariPro to determine what I was seeing. No other stars could be seen as they were below the horizon.

Aries
Time: 1:05 AM
Instrument: Binoculars 
S&T Chart Ref: 4
Thought I had found it earlier this month but quickly realized I had been looking at the wrong section of sky. Did some homework before coming to SCO to ascertain exactly where to look for this almost straight line constellation. Having found Triangulum, Aries was found below it towards to the horizon. I could readily find 41, α and ß but had difficulty finding γ, and not sure if in fact I did find γ. Thrilled to have found this constellation at last!

Triangulum
Time: 1:05 AM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Ref: 2, 4
First seen just after viewing M31. Took greater care to observe it naked eyed also attempted to view it with binoculars. Stars were easily seen against the dark sky.

M8 (Lagoon Nebula)
Time: 1:05 AM
Instrument: Binoculars
S&T Chart Ref: 67, 69, I
Easily able to see the nebula with my binoculars. The nebula was quite bright as was the line of 5 stars in it (or maybe below it?).

M20 (Trifid Nebula)
Time: 1:05 AM
Instrument: Binoculars 
S&T Chart Ref: 67, 69, I
M20 was in the same FOV as M8. Very bright stars with greyish nebulosity.

M21
Time: 1:01 AM + 1:20 AM
Instrument: Binoculars
S&T Chart Ref: 67, 69, I
Moved my binoculars up to the left about 45º from M8 to find M21. Another grey fuzzy.

M22 (NGC 6656)
Time: 1:12 AM
Instrument: Binoculars
S&T Chart Ref: 67, 69, I
Found Kaus Borealis and put it at 5 o'clock in my binocular FOV. Near the centre of my view was a "Y" shape of stars (identified later as 24 Sgr, 25 Sgr and HD170978) and just past it was M22. Another grey fuzzy.

M11 (Wild Duck Cluster)
Time: 1:28 AM + 1:47 AM
Instrument: Visual + Binoculars
S&T Chart Ref: 67
Thanks to Dave Chapman, I remembered how to find M11. I first looked for a semi-circle of stars in the Milky Way just above the Teapot. The stars in this formation were very bright. I identified them as Globular Cluster 6712, δ Scuti and ε Scuti. I knew the "golf club" was part of the semi-circle and that M11 was the "golf ball" adjacent to it. I stared naked eye at the δ Scuti and ε Scuti section of the semi-circle, put my binoculars to my eyes and there it was! The open cluster was a perfectly round, grey fuzzy with a dark centre.

I was so happy to find it the first time that I found it again a few minutes later. Just had to see it a second time before we left SCO.

 Scutum
Time: 1:47 AM
Instrument: Visual
S&T Chart Ref: 67
This constellation escaped me until I could find the 'golf club' of stars adjacent to M11. Started by finding the set-circle of stars that I had predetermined were the Globular Cluster 6712, δ Scuti and ε Scuti. I also noted Aquila and using the semi-circle as landmarks found the 4 stars. This constellation that had eluded me for the past year or more was finally identified. Landmarks for orientation to location was a great help.

Explore the Moon (Binocular) - July 20, 2017

Lunar Phase: Waning Crescent (8.6%)

Moonset: 3:09 AM Eastern       Moonrise: 6:13 PM Eastern
Sunrise: 5:56 AM Eastern         Sunset: 8:59 PM Eastern

Location: Site 13, Kejimkujik National Park
Date: 2017-07-20
Time: 8:15 AM – 9:50 AM Eastern
Temperature: 19° C - 20° C
Equipment: Visual + Binoculars 15x70
Magnification: x15
Transparency: very good (5)
Seeing: very good (5)

Clear cloudless sky with no wind. Began looking for this thin crescent shortly after 8 AM. We made the mistake of searching low on the skyline before finding it in the SE and at about 65° - 70° above the horizon. Very difficult to find because of the clear skies and very bright sun.

With the binoculars, we could make out a dark smudge at about 8’clock. What was truly interesting was how there really wasn’t a terminator like there is at night. I could still make out the remaining part of the Moon, but it was more like a gradual diminution of light from the ‘bright’ crescent to the adjacent areas. The blue area of the Moon just blended gradually into the blue sky. Given the early hour, the sky was a beautiful blue!

Jerry had set up the binoculars on a tripod for my viewing as I couldn’t find it in my 10x30 IS. He then set up a camera on a tripod and captured a couple of beautiful pictures of the waning crescent; first picture was at 8:41 AM. We spent about an hour looking at the Moon until we could no longer see it in the brightening sky.

Jupiter
Time: 9:51 PM ADT
Instrument: Visual 
Jupiter was located below Arcturus, halfway to the horizon.

Scorpius
Time: 1:30 AM
Instrument: Visual 
S&T Chart Ref: 56, 58, J
Scorpius at this time of morning was mostly below the horizon. Could still see Antares, Delta and Graffias easily and perhaps π but the rest were out of observing range.

Capricornus
Time: 1:40 AM
Temperature: 15º C
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 66, 68, 87
Sitting on Slapfoot Beach, Capricornus was right in front of us. The major stars of the constellation were easily identified, and α Cap1 + α Cap2 
were easily identified in the binoculars.

Lyra
Time: 9:51 PM
S&T Chart Reference: 63
Instrument: Visual + Binoculars 10x30 IS
I found Vega visually then used my binocs to view ε α and ß, Zeta and other 3 stars in the 'parallelogram' of Lyra.

Time: 1:46 AM
Instrument: Visual  
I was able to locate Vega through the trees on the shore of our island but could not locate the other stars within the constellation.

M8 (Lagoon Nebula) 
Time: 1:35 AM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 667, 69, I
Was easily able to locate the grey smudge that had the line of stars below it. Not as well seen as in previous observations but easily identified nonetheless.
M7 (Ptolemy Cluster)
Time: 1:50 AM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 58, 67, 69, I
The fog earlier in the evening had cleared off. Although the Teapot was low on the horizon, I was able to locate M7. The 5 brightest stars could be seen with slight nebulosity; the inner stars could be seen in the centre area but there were not very bright.

Ophiuchus
Time: 1:50 AM

Instrument: Visual + Binoculars 10x30 IS
S&T Chart Ref: 54, 56, 67
Seeing: Good (3) - Very Good (4)
Transparency:  Good (3) - Very Good (4)

No wind and only the occasional cloud. Amazed at its size!! I was looking at Scorpius (visually) and noticed an arc of 4 stars above. Using SkySafariPro, I came to realize it was Ophiuchus. What a pleasant surprise! Unexpected discovery! Once all the baseline stars in the curve were identified, I then began the search upwards. WOW! It was huge in the night sky! The Teapot was very small by comparison.

Note 1: When I used SkySafariPro, I also discovered that one of the "stars" in the arc was not a star but rather it was Saturn.

Note 2: used my 10x30 IS binoculars to locate both Yed Prior and Yed Posterior. Couldn't see them as 2 stars using naked eye due to sky conditions.

   

Aquila
Time: 2:05 AM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 64, 65, 66
Could make all the stars except the one past λ and ε. What alerted me to the 
constellation being seen was the line of 3 bright stars at an angle to the direction of the Milky Way - Alshiar, Altair and Tanazed. From there, I looked for θ and ζ then outward for the wings. Despite not perfect conditions, I was rewarded with finding its stars.

Boötes
Time: not noted
Instrument: Visual
S&T Chart Reference: 42, 44, 53, 55
Arcturus could be seen but the stars of the constellation in the first session were covered in fog and trees hid them in the second session. Not a great night for this constellation.

 

Coathanger / Collinder 399
Time: 2:05 AM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 65
After locating Cygnus, I put up my binocs to where I thought it would be - et voilà! First attempt to locate it. All 10 stars easily seen. Went back to Cygnus to locate Albireo to use it as the start point to locate the Coathanger. Put my binocs up to find it then went 45º downwards and located it again. Tony Schellinck taught me well!

Delphinus
Time: 2:10 AM
Instrument: Visual
S&T Chart Reference: 64
Located Delphinus visually throughout this session. All 5 stars could be seen. Didn't attempt to use binoculars.

M13 (Hercules Cluster)
Time: not recorded
Instrument: Binoculars, 10x30 IS 
S&T Chart Reference: 52, 54
Used Corona Borealis to locate M13 with binoculars. Grey fuzzy was easily seen between η Hercules and ζ Hercules.

After a short sleep we were once again the go getting ready to take down camp when Jerry noticed the waning crescent Moon. Almost missed it against the clear blue sky. Read more about it at Explore the Moon (Binocular) - July 20, 2017.

Travelling by bus from Ottawa to the Diefenbunker, I noticed the Quarter Moon high in the sky. I couldn’t make out any details other than the fact it was a 1/4 Moon.

I took out my binoculars and attempted to look at the terminator. Despite the image stabilization feature of the binoculars, the bus bounced too much to get a good look. There was no time to look at the Moon when we arrived and when we came out of the Diefenbunker it had clouded over. No Ottawa Star Party at the Ottawa GA.

Clear skies with only a few clouds. No wind. A few fireflies in the greenery near the shore. While Jerry was setting up his time lapse equipment, I was getting my bearings and determining the stars that rose in the night sky visually first.

However, my first order of business was to look at the Moon while it was still up high enough above the tree line at SCO. Not much time for Explore the Moon (Binocular) - June 26, 2017.

M70
Time: 9:50 PM ADT
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 67, 69
Tried to find M70 again with binoculars by slowly going along the imaginary line in the Teapot between Ascella and Kaus Australis. Did not succeed.

  

10:00 PM
We looked up, straight up to find the Keystone of Hercules. Looked for the backwards "C" known as Corona Borealis. All 7 of the brightest stars forming the Corona were easily seen. After pointing this out to Jerry, I used two methods to find M13 (Hercules Cluster):
   1- Went down 1/3 distance from η to ζ on the NW border of the Keystone; and
   2- Use the Corona Borealis, following the arc counter-clockwise to point right to it. 

Given sky conditions on any given night, we appreciated that only one of these methods might be used. Tonight's excellent seeing and transparency meant both could successfully be used.

 

10:10 PM
For the second time in a month, Scorpius was well above the horizon and at about a 45° angle in the sky. θ and η were about 5° to 10° above the horizon; this was the brightest and highest I can recall seeing this constellation at home in Nova Scotia!

Adjacent to Scorpius was the Teapot (the asterism in Sagittarius). It, too, was at about 5° to 10° declination and was completely horizontal! Ascella and Kaus Borealis were level with the horizon and Kaus Borealis pointed straight up. Never saw it level before. Came close in Utah. All stars within the asterism were very easily located and identified. 

10:15 PM - 10:26 PM
According to SkySafariPro, Jupiter was located in Virgo. Located Spica. Jupiter was bright and at a similar declination to Spica. Virgo seemingly wrapped her arm around the planet. 
Saturn was also visible this evening. Found Saturn adjacent to Antares in Scorpius.

10:42 PM
I noticed a satellite going across my visual field from West to East. My phone identified it as Taingong.

11:02 PM
Was looking in the general area of Virgo when an iridium flare caught my eye travelling SW to NE above Spica towards Jupiter.

11:16 PM
With the Teapot so high and level against the horizon, it was easy to find M6 (Butterfly Cluster) by going 1.5 FOV from Kaus Borealis.

11:18 PM
I decided that given Spica was so bright, I would use my S&T Pocket Atlas to identify the other stars in this constellation. 

Not disappointed!
   a) 109, τ, &mu:, and Syrma/ι were the first stars in addition to Spica that I could see.
   b) Next came ξ, Vindemiatrix, Porrima. Vindemiatrix was particularly bright.

10:30 PM
Started at Kaus Borealis and followed a line to the midpoint in the spout, then the same distance to M8. M20 was just a little above M8 in the same FOV. This was not difficult to find given the excellent sky conditions.

10:37 PM
Could see all the stars in the Big Dipper naked eye; did not use binoculars. Polaris was easily found using the Dipper's pointer stars. I did not attempt to find Ursa Minor stars this evening.

11:28 PM
I knew Delphinus was near Altair and Cygnus. Found the stars naked eye but it did take a while to locate all 5 star. When I tried using my binoculars, there were too many stars for these untrained eyes to single out the 5 stars of Delphinus.

11:38 PM
I turned around toward the Warm Room and storage shed to see Cassiopeia and 3 of the 4 stars in the Square of Pegasus. I visually drew a line from Schedar towards Alpheratz and guessed where M31 was located. I was lucky in that I found it as soon as I held up my binoculars. The oval shape of the Galaxy was grey with a slightly brighter centre. I did not look for the remaining parts of Pegasus at this time.

12:02 AM
M22 was easy to find using the lid of the Teapot. Using the 10x30 IS binoculars, I went left of the top of the lid of the Teapot (Kaus Borealis) about 30° to a small group of stars shaped like a "Y" then went past them to M22. It appeared as a grey fuzzy object with no discernible stars.

12:05 AM
I visually drew a line from Kaus Australis to Kaus Borealis, then extended the line 3/4 of the distance more. M25 appeared as a grey fuzzy round object in the binoculars.

1:40 AM
Jerry and I knew M11 was somewhere near Aquila, at or near the edge of what we referred to as the bright bay above the Teapot. He found it with the 15x70 binoculars mounted on my tripod. The open cluster was small, grey and compact. To find M11, we located the semi-circle of stars (similar in configuration to Corona Borealis). We followed the stars counter-clockwise and they pointed to M11.

NOTE: Later on June 27, 2017, Dave Chapman told us M11 is sometimes referred to as the "golf ball" as some of the stars adjacent to it seemingly form a "golf club". In reviewing the photos Jerry took earlier, we were easily able to identify both the ball and the club. Note that the club is upside-down so to speak.

When we arrived at SCO, the sliver of a Moon was peeking through the evergreens. There wasn't much time before it disappeared. I was able to find Mare Crisium (the western shore still in shadow at the terminator), Cleomedes, the Gang of 4 and several other craters in the lower segment of the crescent. The remaining surface of the Moon was dark but the 'full' Moon could be seen (Earthshine).  

When it disappeared, I went on to general observing. Here are the notes for General Session - June 26-27, 2017.

Clear except for a high haze that Halifax light pollution seemed to bounce off of.

8:35 PM - 8:42 PM
The early part of this session was finding a few objects for Explore the Moon (Binocular) (June 25, 2017)

At some point in the later portion of the observing session, I noted how easily the Summer Triangle could be seen - Deneb in Cygnus, Altair in Aquila and Vega in Lyra. After finding the stars of the Triangle, I then looked at their related constellations briefly.

1:38 AM
I was able to locate the Keystone of Hercules using the Corona Borealis as the pointer. Looking between η and ζ Herculis, I found the small grey fuzzy known as M13, a.k.a. the Hercules Cluster. Couldn't make out the star field definition.

1:47 AM
Could only find Polaris, Pherkad and Kochab in Ursa Minor. Could not find the other stars either naked eye or with my binoculars.

1:57 AM
From Albireo, I went 1/2 FOV and found the Coathanger. All 10 stars of the asterism were easily found.

2:02 AM
In Cygnus, I followed the stars from Deneb down to Albireo. Although I could find the two stars of Albireo in my binoculars, I couldn't distinguish the blue and yellow.

2:10 AM
Jupiter was easily identified. I found it basically at the same declination as Arcturus. It was quite bright! Didn't make note of the location of its 4 moons.

I looked westward out our bedroom window to see a sliver of a Moon hanging just above the treeline, with a bit of a rough edge on the terminator. Grabbed my binoculars and ran outside only to find the Moon had disappeared. I went back in thinking I was too low to see it in the backyard, only to find it had disappeared from View.

So much for viewing it. :(

Following this session, I went back in the house for a few hours. I went back out in the wee hours of the morning to continue observing other celestial bodies. Look at General Session - June 25-26, 2017.

Very clear skies, no cloud. Amazing night! We had frozen the night before in the Rocky Mountains but on this evening we wore shorts and t-shirts to watch the night skies evolve. Set up our camp chairs next to the tent in the open field and enjoyed watching the Moon rise. Earth's Shadow and the Belt of Venus were bonuses. The fireflies in the field’s hedging that spread before us and along the river's edge twinkled like mini-Christmas lights.

General Session - May 29, 2017

On one of the evenings while staying in Moab, Utah, I drove to the Dead Horse Point State Park to take in the sights from the elevation. While at the Grand View Point on the park, there was a beautiful panorama of the Earth's Shadow and the Belt of Venus. A father and son were taking time-lapse of the view but had no idea what they seeing. They thanked me for explaining the colour change that they attributed to clouds and they couldn't wait to process their video. The Colorado River is below (centre). In the back left rising above the landscape are the La Sal Mountains; unfortunately, the roads into the mountains were closed due to construction when I was there. The square pools of water seen in front and below the mountains are potash drying pools.

I left Grand View Point as it started to get dark. Not sure I wanted to drive the narrow winding road in the dark, especially with the possibility of not seeing cattle on the road in time.

Instrument: Telescope (type and eyepieces used unknown)
Transparency: Excellent!
Seeing: Excellent!
Temperature: 14° C - 12° C

Elevation: 5,900 ft / 1,800 m
No clouds, just a light breeze.

I had made arrangements with Red Rock Astronomy to have a sky tour while in Moab. Alex, the proprietor, set up in a small, elevated, open field. Absolutely incredible 360° view of the land around us from our location. It was such an "oh wow" moment to see astronomical objects almost at eye level and to see them so far above the horizon, especially Scorpius! And the stars were so pinpoint!

Alex was showing the group several objects in the night sky through his telescope, proving information about and at times the associated star lore. Because of the number in attendance and the time he allotted for the session, participants only had 15 seconds at the eyepiece. I had this brief view of M44 (Beehive Cluster).

 

Jupiter
Time: 10:12 PM 
Instrument: Telescope 
The planet and its 4 Moons were so so clear! Could even see the Red Spot!
Scorpius
Time: 10:20 PM
Instrument: Visual + Telescope 
S&T Chart Ref: 56, 58, J
I was paying attention to the Big Dipper and watching the stars come out as the sky darkened to identify Polaris. I literally turned around on the spot I was standing and there was Scorpius in all its glory completely above the horizon! Every star in the constellation was found and were very bight and non-twinkling against the night sky. Theta (θ) and Eta (η) were above the horizon at approximately 20° declination. It was so exciting to see!! No words could describe how amazing it was to see this constellation so high in the sky compared to what we see in Nova Scotia.

     

Teapot in Sagittarius
Time: 10:10 PM
Instrument: Visual
S&T Chart Ref: 66, 67, 68, 69, I
I was excited, thrilled, in a state of disbelief to see the Teapot with Ascella and Kaus Australis almost horizontal and at 20° declination. I have never seen it so high nor so clear and bright against the dark sky. Incredible! Couldn't help but stare at it for several minutes while Alex set up his telescope.

General Session - May 25, 2017

We were on our way to Moab, Utah for Jerry to attend Ron Risman's 4-day time-lapse workshop. En route, we decided to camp at Mesa Verde National Park in New Mexico. It was an interesting to go to the cave city and visit the site where people lived halfway up from the Valley and half way down from the top of the mesa. They had to climb up or down with food, water and all other things needed for their village to thrive and to build. Interesting history told by a Ranger who just loved this park and who declined offers to move to other national parks.

Constellation: Aquila, Boötes, Leo, Lyra, Scorpius
Asterism: Teapot

Elevation: 8,427 ft / 2,569 m

10:00 PM
I was able to find all the stars within Leo. Denebola was the star that initially caught my eyes on the way back from the Ranger talk

12:00 AM
Looked at the sky from the campsite itself. Clear skies until clouds moved in later in the AM.

Noted Altair, Alshain, Tanazed and Delta; didn't look further along the constellation to find the remaining stars. Arcturus was very bright against the dark skies. Able to visually locate all the stars in Lyra. Located Scorpius (original notes taken were not detailed).

Jupiter also located in Virgo near Porrima.

I found the Teapot. I looked up from its lid star (Kaus Borealis) at a 45º angle. I found the little "Y" star formation using the binoculars and just past it was the little fuzzy known as M22. I then started at Kaus Australis and extended an imaginary line to Kaus Media. I used the binoculars to find M224  twice that distance above Kaus Media.

Temperature: -6° C

Semi-cloudy skies until binoculars revealed a haziness (high cloud or humidity). The Moon in particular reflected light onto the clouds.

Coathanger / Collinder 399
Time: 11:00 PM
Instrument: Binoculars 10x30 IS
Magnification: x10 
Despite the atmospheric conditions, all stars in the Coathanger were easily found.


Leo
Time: 11:18 PM
Instrument: Visual
Some clouds but otherwise clear. Denebola caught my eye after seeing Regulus and part of the Sickle asterism. The stars in the hind end were not all seen, especially not the legs, but Denebola and Zosma were clear with barely visible Chertan. Leo's hind legs were hidden by cloud. The stars in his mane could barely be seen but Algieba, Ras Elasid Australis and Ras Elasid Borealis were visible.

Sounds of a loon calling out on Second Lake - a beautiful accompaniment.

   

Conjunction - Moon-Jupiter-Spica
Time: 11:35 PM
Instrument: Binoculars 10x30 IS
Magnification: x10 
Spica was barely visible as a point of light. Jupiter was quite bright and due to the atmospheric conditions appeared as a 'twinkle' in my binocular view.
    

Gemini
Time: 11:35 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 23, 25 
Could easily see Castor and Pollux but the haze made it difficult to see the other stars in the constellation that was found at approximately 45º declination.

Clear skies; little if any breeze. This session began with looking for objects in the RASC Explore the Moon (binocular) program. I then went looking for constellations and the conjunction.

Conjunction: Mars-Uranus-Venus
Time: 8:25 PM 
Instrument: Binoculars 10x30 IS + 15x70
Magnification: x10 + x15
Located Venus low on the western horizon in our back yard, then located Mars. Uranus was very faint but found it with averted vision in both pairs of binoculars.

     

 

Winter Circle
Time: 6:45 PM & 8:15 PM 
Instrument: Visual
The Moon (Waxing Gibbous, 57.9%) was in essence in the Centre of the Winter Circle.

At 6:45 PM, Orion couldn't be easily seen because of the brightness of the Moon.

At 8:15 PM, it was very visible. All the stars of the Circle were clearly and easily viewed - Capella, Aldebaran, Rigel, Sirius, Procyon, Pollux, Castor.

NOTE: The night before, I could only see Pollux, Capella, Aldebaran and Sirius due to the thin cloud cover and the First Quarter Moon.

 
   

Winter Triangle
Time: 9:16 PM 
Instrument: Visual
Dave Chapman had emailed the Halifax Centre Discussion List to remind us there was also a Winter Triangle - Procyon, Sirius & Betelgeuse. Tonight this asterism appeared to be an equilateral triangle.

Apennine Mountains very easily seen; caught your eye because of their brightness.

Mare Located:
Fecunditatis, Frigoris, Nectaris, Serenitatis, Tranquilitatis, Vaporum

Craters:
Alphonsus, Arzachel, Klein and Ptolomaeus plus two small craters were on the lower half of the terminus. Upper part of the terminus was rough (craters? mountains?) compared to the terminus between Ptolomaeus and this feature. 
   
Visual:
Thin cloud plus perhaps the First Quarter Moon made for poor visibility of the Winter Circle but was able to see some of the stars around the Moon plus the adjacent Pleiades. 

NOTE: The dark line across the image is not an astronomical feature; it was the line drawn between this sketch and the one above.

This session began with looking for objects in the RASC Explore the Moon (binocular program). I then went looking for constellations and DSOs. The First Quarter Moon was centred in the Winter Circle, but was able to identify some of the brighter stars - Pollux, Capella, Aldebaran and Sirius.

M45 (Pleiades)
Time: 9:25 PM 
Instrument: Binoculars 10x30 IS
Thin cloud and First Quarter Moon limited visibility but was able to see the 5 brightest stars of the Pleiades. Looked like a small, misshapen Big Dipper through the hazy clouds. The typical Pleiades brightness and beauty was lost under these conditions.

   

Boötes
Time: 9:32 PM 
Instrument: Visual + Binoculars 10x30 IS
From our side deck, saw a bright star at approximately 30° and a configuration of stars to the NW. The street lights made it difficult to see all the stars but did see very clearly Arcturus, Rho, Izar & Eta. The others were hidden by our maple trees and the neighbour's home.

An incredibly clear night. Clearer than we have seen in quite a while. Didn't look for M36, M37 or M38 in Auriga. Found an interesting fact online later this evening: this is the site of the anti-Galactic Centre (opposite centre of the Milky Way).

Leo - Sickle Asterism
Time: 8:10 PM
Location: Home
Instrument: Binoculars 10x30 IS
Magnification: x10
S&T Chat ref: 34, 35

The exciting moment for me this evening was the discovery of Leo over the rooftop of our home. I wondered what the semi-circle of stars were part of anything or whether it was wishful thinking on my part. Come to find out through SkySafariPro that what I was seeing was the sickle. The others stars of the constellation (including Denebola) were hidden by the house. When I attempted to find the constellation on another side of the house, the street lights obscured my view. However, I did clearly see the 5-star sickle asterism that ended in Regulus (α Leo).

     

M45 (Pleaides)
Time: 8:10 PM
Location: SCO
Instrument: Visual + Binoculars 10x30 IS
S&T Chat ref: 14, 15, A
M45 was easily found adjacent to Aldebaran. Seen visually
then then viewed with the binoculars.

Ursa Major /  Ursa Minor
Time: 8:10 PM
Location: SCO
Instrument: Visual + Binoculars 10x30 IS
S&T Chat ref: 31, 32, 33, 43, F
The little bit of cloud quickly dissipated; Big Dipper and Polaris easily found. Surprised that I could finally see all the stars in the Little Dipper!

Orion
Time: 8:20 PM
Location: SCO
Instrument: Visual + Binoculars 10x30 IS
S&T Chat ref: 14, 16 B
Have observed this constellation numerous times over my lifetime. This is the first time recording an observation of the constellation versus just M42. 

   Visual
Betelgeuse, Bellatrix, Saiph and Rigel site bright. Orion's Belt (Alnitak, Alnilan, Mintaka) easy to see as was the location of his sword's 3 stars. Nebulosity in the centre star of the sword discernible. Didn't see or look for Meissa (Orion's head). I think I saw the shield but wasn't sure.

   Binoculars
Used the binocs to better view the main stars (α & β Orionus), the belt stars and sword. In binoculars, the sword stars looked like 3 sets of double stars:
a) NGC 1981: 2 bright stars beside each other at the top of the sword.
b) M42 / M43: M42 more readily seen; a less bright and seemingly attached M43 was seen.
c) Iota Orionus: Saw 3 stars at the bottom near Iota Irionus but do don't know their relationship to Orion, if any (shown in the sketch as an 'x').

   


     

              Auriga
Time: 8:45 PM
Location: SCO
Instrument: Visual
S&T Chat ref: 12
Capella was easy to find in the Winter Circle. The other 5 stars of the constellation were easily visible with naked eye. This constellation wasn't difficult to find regardless of where in the sky they were located.

Canis Major
Time: 8:52 PM
Location: SCO
Instrument: Visual
S&T Chat ref: 7
Didn't look for M41. Sirius was easily detected. From Sirius, I found Mirzam and Adhara. Wizen and Aludra took some time to find naked eye but were eventually found. Didn't find the other stars of the constellation (marked as an 'x' in the sketch).
     
Cassiopeia + Kemble's Cascade
Time: 9:00 PM
Location: SCO
Instrument: Visual
S&T Chat ref: 1, 3, 72
Easily identified all 5 stars visually. used it to locate
Kemble's Cascade. Didn't sketch them.

Hyades (Melotte 25, Collinder 50, Caldwell 41)
Time: 9:15 PM
Location: SCO
Instrument: Visual
S&T Chat ref: 15
Open cluster of stars in essence surrounding Aldebaran in Taurus. Varying brightness. Looked like a very broad, undefinable star field (couldn't see a 'V' shape?). A very open cluster! I did not draw this well other than to show the location.

   

Winter Circle
Time: 10:12 PM
Location: SCO
Instrument: Visual
At 8:15 PM, a little cloud cover in the SE soon dissipated to once again reveal Orion and Canis Major. Came back out at 10:15 PM to clear skies and -7° C. The winter circle was so clearly identifiable this beautiful clear night. I was so excited about seeing the circle that, other than Orion and Leo, I didn't locate stars in the other constellations that were so high in the sky. Missed opportunity initially.

After observing the Moon-Venus-Mars conjunction, I identified stars in 6 constellations: Orion, Gemini, Auriga, Canis Major, Taurus and Canis Minor. NOTE: Canis Minor couldn't be made out despite Procyon being very visible.

Now that the sun was up, the features were somewhat bright but not completely washed out. Drew some of the features I saw but I obviously did not make much attempt at identifying them other than Posidonius and Tycho. At this point, I was getting used to the newly acquired 8" Meade SCT "push-to" telescope. With the star diagonal, I was sometimes confused as things were not only backwards (as they should be) but felt as though sometimes they were backwards and upside-down. Don't ask - I can't explain.

Tony Schellinck had pointed out Perseus in a talk and observing session in Liverpool earlier this month. Was able to find all the stars in Perseus at that time. This evening, while looking SE while standing on our side deck, Mirfak was quite visible as was Algol but for some reason couldn't see the others as well. Didn't look for them in binoculars.

Andromeda & M31 (Andromeda Galaxy):
Time: 9:50 PM
Equipment: Visual + Binoculars 10x30 IS

This was a surprise! A discovery in our own backyard! Facing the downhill neighbour's yard, I noticed a very bright star. It didn't appear to be associated with other stars or constellations nearby. SkySafariPro identified the bright star as Fomalhaut in the constellation Pisces Audtrinus. I then looked up the constellation and could identify 7 of the 10 stars comprising the constellation; the other 3 were hidden by the neighbour's trees.

No breeze and only the occasional cloud. Fog rolled in from the west and by 11:00 PM the observing session ended. NOTE: Attempted to find M5 located north of Zubeneschamalli but couldn't due to the fog.  

Libra:
Time: 10:30 PM 
Looked for Scorpio's Antares and Delta (δ) to get an orientation to begin looking for Libra. I was looking for α (Zubenelgenubi) and β (Zubenschemali) and found them readily, then began looking for other stars within the constellation. Was delighted I could find all of them and that the "weigh scales" were so easily recognizable! Once found, I could find them again using naked eye.

M13 (Hercules Cluster):

Seeing: Very good
Temperature: 11.5° C
Obtained a ride from Dave Chapman and Chris Young to head off to SCO whereas hubby headed to St. Margaret's Bay for a timelapse session. Windy at first at SCO and then stopped.

M4: (NGC 6121)
Time: 9:45 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10 
S&T Chart Ref: 56, 58

Chris Young provided guidance on how to find it. Antares was located low in the sky with Mars and Saturn nearby. The grey circular fuzzy was seen with averted vision at approximately 5 o'clock from Antares.

M20 & M21:
Time: 9:45 PM + 11:37 PM ADT
Equipment: Binoculars 10x30 IS + Thurlow Binoculars
Magnification: x10 + x20
S&T Chart Ref: 67, 69, I
Initially used my binoculars but then used the Thurlow Binoculars with Chris Young's assistance. We were able to clarify the boundaries between M20 and M21. It was much easier with the Thurlow's x20 magnification to make that distinction.

Boötes:
Time: 9:52 PM ADT
Equipment: Visual 
S&T Chart Ref: 42, 44, 53, 55

Thanks to Chris Young for identifying this and showing me how to find it by following the arc of the Big Dipper's handle ("arc to Arcturus") then looking for the necktie/kite shape of the constellation. Noted it was adjacent to Corona Borealis and was tilted away from it. Identified stars in the constellation.


M22, M24, & M25: 
Time: 10:22 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10 
S&T Chart Ref: 67, 69, I

Chris Young and I wanted to get a better sense of location, size and boundary in relation neighbouring Messier objects. We found all 3 objects with our binoculars and had no difficulty in doing so.

     To find M22:
It was easy found with Kaus Borealis at about 5 o'clock in the boundary of my FOV, then moved the eyepiece a little NE to view a small Y-shaped asterism with M22 to the left of it. The circular cluster was denser in the centre and fairly bright. Didn't draw the stars in it.

     To find M24: (Sagittarius Star Cloud)
Time: 10:40 PM ADT
Equipment: Binoculars 10x30
Magnification: x10 
S&T Chart Ref: 67, I
We followed the line from Kaus Australis to Kaus Media in the Teapot, then went up 2 twice that distance. We saw a very dense star field that I couldn't fit not 1 FOV.

     To find M25:
Time: 11:10 PM ADT
Equipment: Binoculars 10x30
Magnification: x10 
S&T Chart Ref: 67, I
Found a dim patch of diffuse light. Couldn't make out individual stars very well at all. Thanks Chris Young fo helping locate this one!

Lyra:
Time: 11:00 PM ADT
Equipment: Visual + Binocular 10x30 IS + 16" Newtonian Reflector with 8mm eyepiece, f1800, x225 mag
S&T Chart Ref: 63

Thanks to Chris Young!  Located Vega then the parallelogram below it visually. All 4 stars of the parallelogram were easily identified but they were pale compared to Vega.


Lyra, Epsilon1 and Epsilon2:
Time: 11:00 PM ADT
Equipment: Binocular 10x30 IS + 16" Newtonian Reflector with 8mm eyepiece, f1800, x225 mag
S&T Chart Ref: 63
Chris Young and Dave Chapman then wanted to show me Epsilon1 and Epsilon2 using binoculars and SCO's 16" reflector telescope.
a) Binoculars: Looke for Vega then moved to Epsilon. Separation was evident albeit blurred.
b) Telescope: Found it in the finder scope, then had to move it slightly to see the "double-double". The pair on the left was horizontal; the pair on the right was vertical.


Lyra, Zeta1 and Zeta2:
Time: 11:10 PM ADT
Equipment: Binocular 10x30 IS + 16" Newtonian Reflector with 8mm eyepiece, f1800, x225 mag
S&T Chart Ref: 63
Found the triangle earlier in the evening with binoculars. Zeta1 and Zeta2 were not sen with binoculars but were viewed wth the telescope. First found it in the finder scope then slightly adjusted it for the eyepiece.


Ursa Major - Alcor (79 UMa) & Mizar (80 UMa):
Time: 11:15 PM ADT
Equipment: Binoculars 10x30 IS + 16" Newtonian Reflector with 8mm eyepiece, f1800, x225 mag
S&T Chart Ref: 42, 44, 53, 55

a)Visual: Found Mizar and Alcor plus a 3rd faint star to the left that would form a triangle, just as I had seen the night before eat the Swiss Air Monument.  
b) Binoculars: Found the 2 stars plus a dimmer smaller star to their left to forma  triangle.
c) Telescope: I was shown Mizar in the telescope, then was made to find Mizar A and Mizar B using the telescope without the go-to capability. I was able to find them; they were close together with Mizar B located about 4 o'clock to Mizar A.


Kemble's Cascade:
Time: 11:30 PM ADT
Equipment: Visual + Binocular 10x30 IS
Magnification: x10
S&T Chart Ref: 11, 13

Thanks to Dave Chapman who introduced this to me.
a) Visual Location: Found Cassiopeia. Drew an imaginary line from Beta to Epsilon, then extended the line the same distance from Epsilon. Saw a faint bright line extending southwards towards the horizon.
b) Binoculars: Put my binoculars up to see what I thought was the start of the Cascade. Saw 4 bright stars in almost a straight line then the multiple well-spaced stars in a cascade towards the horizon and then terminated in stars arranged like the end of a hockey stick. A much brighter star half way down.


Capricornus - β1 & β2, δ1 & δ2:
Time: 11:40 - 11:50 PM ADT
Equipment: Visual + Binocular 10x30 IS
Magnification: x10
S&T Chart Ref: 66, 68, 77

Dave Chapman agreed to help me find the two sets of double stars in Capricornus - Delta1 and Delta2 plus Beta1 and Beta2. We found the constellation visually then located Delta Capricornus that appears as a single star. However, with binoculars, 2 stars (optical double) appeared with one just slightly above the other. We then looked below them for Beta Capricornus (Dabih). Again 2 stars were visible at this location, one brighter than the other. I failed to draw or explain in my rough notes the relationship of these two stars.



M57: (Ring Nebula)
Time: 11:47 PM ADT
Equipment: SCO Skywatcher 16" Dobsonian, 8 mm eyepiece
Magnification: x225
S&T Chart Ref: 63
Couldn't see this visually with binoculars. The telescope showed a donut-shaped object, more dense on the outer edge and less dense as went closer to the centre opening. NOTE: Also saw this Aug 26/16 at Nova East using mark Dryden's Obsession telescope.

Explore the Moon (Binocular) - September 9, 2016

First Quarter Moon at 8:14 PM ADT
© Jerry Black - Nikon D800, ISO 100, 1/15 sec @ f/3.5

Lunar Phase: 1st Quarter (46.6%)

Location: Home
Date: 2016-09-07
Time: 9:00 - 11:00 PM ADT
Equipment: binoculars 10x30 IS
Magnification: x10
Seeing: not recorded
Transparency: not recorded

The evening began with the First Quarter Moon visible above the trees. This evening is to be devoted to Moon watching but will look at constellations and DSOs when we can do so. Jerry has the Meade LX200 set up with his camera so this session for me is through two pairs of binoculars - 10x30 IS and 15x70.

9:00 - 9:30 PM:
Reinforced ability to view the following seas: Crisium, Fecunditatis, Serenitatis, Tranquilitatis.

New to my observations tonight were:
a) Mare Vaporum
b) Mare Frigoris & Lacus Somnorium
c) eastern portions of Mare Imbrium
d) Alps Mountains on the north shore of Mare Imbrium
e) Could make out the line of the Apennine Mountains running SW to NE at the bottom of Mare Imbrium and north of Mare Vaporum
f) Could make out the large, oval-shaped crater Petavius on the southern border of Mare Fecunidtatis.
g) Cleomedes was visible above the north shore of Mare Crisium. It wasn't attached to the Mare.
h) Oval-shaped Posidonis was seen on the shore between Mare Serenitatis and Lacus Somnorium.

i) Just south of the Alps were the following craters:
          i- Cassini
         ii- Aristillus
        iii- Autolycus (the smallest)
        iv- Archimedes (the largest)
j) Sinus Medii below which I could easily see the following craters (top to bottom): 
         i- Herschel
        ii- Hipparchus 
       iii- Halley
       iv- Ptolomaeus
        v- Alphonsus
       vi- Arzachel
9:30 - 9:45 PM:

Could see the crater Plato on the terminus. It was bright on the rim (western edge) whereas most of the crater and its eastern edge were in shadow.

9:45 - 10:00 PM:
My focus was the lower quadrant, trying to identify, if at all, the "Gang of Four" craters. I am quite sure I found Vendilinus and Petavius. If I identified Furnerius, it was the centre of a feature that looked like a mini-Tycho. Was not sure about Langrenus. All the craters were whiter than the surfaces around them; no ridges were detected by shadows.

10:00 - 11:00 PM:
Spent the time on constellations as found in General Session - September 9, 2016

    From Keystone of Hercules to the Milky Way

Summer Triangle (astronomical asterism) 
Time: 8:40 PM ADT
Equipment: Visual 

Located the brightest stars in Cygnus, Lyra and Aquila - Deneb, Vega and Altair respectively.

Boötes
Time: 8:45 PM ADT
Equipment: Visual
S&T Chart Ref: 42, 44, 53, 55

Located the Big Dipper then arced to Arcturus to locate and identify the stars in this constellation.

Ursa Minor
Time: 8:50 PM ADT
Equipment: Visual + Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 41, 51

No low clouds but occasional high clouds impeded the view. Located the North Star (Polaris) then followed the stars to the bucket. I could easily see Zeta, β and Gamma UMi but not Eta UMi. This was the second night I had difficulty seeing it.


Cepheus (The King) 
Time: 8:53 PM ADT
Equipment: Visual 
S&T Chart Ref: 71, 73

Found between Cassiopeia and Cygnus, adjacent to Polaris. I knew Cepheus' roof pointed towards Polaris, so began my visual search near Cassiopeia and Polaris. Found it! I only looked for the stars that were brightest and formed the "house". Must look for other stars on a clearer night and when light pollution is not a factor.

NGC 869 / NGC 884 
Time: 9:08 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 1, 2, 13

Viewed this with Jerry. Confirmed I knew how to find the double cluster.

Sagittarius 
All stars of the Teapot were easily seen above the clouds on the horizon. Mars, Saturn and Antares were in close proximity. 

M7: (Ptolemy Cluster, NGC 6475) 
Time: 9:18 PM
Equipment: Visual
Magnification: 
S&T Chart Ref: 58, 67, 69, I

Easily found it visually as a very large and bright object with direct vision and even brighter with averted vision. Although close to Scorpius, found it easier to find using the Teapot. Numerous stars with very bright core and those outside the core were equally as bright. Not as resplendent as the Pleiades - but close!

M8: (Lagoon Nebula) 
Time: 9:27 PM
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 67, 69, I

Started at Kaus Australis and continued to the mid-point of the spout, then an equal distance again to M8 (or extend the line from the spout 2 FOVs). A line of 5 bright stars highlighted the object and its oblong shape. Through binoculars, I could see the brightness and the grey of the surrounding stars. In same FOV as M20.


M20: (Trifid Nebula) 
Time: 9:27 PM
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 67, 69, I

Started at Kaus Australis in the Teapot and continued to the mid-point of the spout, then an equal distance again to M20. In same FOV but just slightly above M8. The stars didn't appear as bright as those in M8. Looked like the brighter stars formed a shape similar to M13 then had a large grouping just off-centre. Star field looked somewhat circular and a fuzzy grey.

Also refer to Messier Catalogue - M020 (NGC 6514 / Trifid Nebula) - September 3, 2016

M21:  
Time: 9:27 PM
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 67, 69, I

Found M20 and M21 in close proximity and in same FOV. Given their proximity, wasn't sure that both were seen versus only M20. There was a small greyish, mottled area NE of M20 that led me to believe I did see it. Couldn't discern bright stars in M21 as I had in M20. I didn't sketch it.

M13: (Hercules Cluster) 
Time: 10:13 PM
Equipment: Visual + Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 52, 54

Found Corona Borealis then the Keystone of Hercules then M13 with direct vision then with the 10x30 binoculars.

M45: (Pleiades) 
Time: 11:00 PM  
Equipment: Visual + Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 14, 15, A

Because of the light pollution towards Halifax, we had to wait until it was higher in the sky to observe (~ 60°). Used averted vision to view it brighter in the sky than seen by direct viewing. Binoculars allowed viewing of the brighter "sisters" and "parents" with some of the secondary stars within. Viewed this at 11 PM and again at 2:05 AM. 

Triangulum: 
Time: 11:00 PM  
Equipment: Visual 
S&T Chart Ref: 2, 4

Confirmed I knew how to find the constellation as taught by Dave Chapman. Due to light pollution from Halifax, had to wait until it was higher in the sky to observe.

Pegasus & Square of Pegasus 
Time: 12:22 AM 
Equipment: Visual 
S&T Chart Ref:74, 75

I located the Square of Pegasus using Cassiopeia and Andromeda as markers. I was able to see the stars o fate Square, plus some of the other stars of the constellation, but not all. I think I found Enif.

Aquila: (The Eagle) 
Time: 1:18 AM 
Equipment: Visual 
S&T Chart Ref: 64, 65, 66

Sitting and looking at St. Margaret's Bay, I remembered Chris Young saying Altair was in the Eagle (Aquila). This evening, Aquila with its adjacent stars β and γ (gamma) were evident. Looking at SkySafariPro, we determined the location of the other stars in the constellation. We were pleased/thrilled that we were able to find the 3 stars in the head of the Eagle as well as θ (theta), λ (lambda), δ (delta), and ζ (zeta). Didn't search for Eta or Iota (another time?).

Jerry and I were setting up for time-lapse imaging and binocular observing respectively. We watched as the crescent went down below the horizon as a red-orange sliver. Absolutely breath-taking and so amazing at how quickly it "disappeared" at the horizon. Took a picture of it but Jerry deleted it when formatting the card for time-lapse.

Started at Albireo at the top of my FOV then moved another .5-1 FOV and there it was! Could easily put my binoculars up there afterwards and land on or near it. Can also be found 1/3 of the way between Altair & Vega. NOTE: NASA refers to this as an asterism.

   

        

M31 (Andromeda Galaxy)
Time: 11:05 PM ADT
Equipment: Visual + Binoculars 10x30 IS

M45 / Pleaides / Melotte 22 / "7 Sisters"
Time: 11:40 PM ADT 
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 15

This wasn't the first time I found the Pleaides, but this was the first time it was so visible and therefore easily seen naked eye. I am always impressed with this open cluster and its beauty.

The 7sisters and their parent were very bright with numerous stars surrounding them. It always reminds me of a distorted, shrunken Big Dipper - shorter handle (1 main star) and a smaller squashed bucket.

Also refer to Messier Catalogue - M045 ("7 Sisters", Melotte 22) - September 2, 2016 

   
Triangulum 
Time: 11:40 PM ADT  
Equipment: Visual  
S&T Chart Ref: 2, 4
Look for Andromeda (M31), then find the constellation below Mirach and Almach. Thanks again to Dave Chapman! With naked eye, the 3 brightest stars were very visible and stood out in the dark sky. Delta Triangulum and 7 Triangulum were not seen visually; hope to find them another night.
  

NGC 869 / NGC 884 
Time: 11:45 PM ADT  
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 1, 2, 13

Thanks to Art Cole for instructions on where to find the double cluster. Both clusters are easily discernible within the same FOV, one just above and to the right of the other. Diffuse field around a bright centre for both NGCs. Found them between Ruchbah of Cassiopeia and Miram of Perseus. I was impressed - very cool!

Capricornus 
Time: 12:30 AM ADT
Equipment: Visual
S&T Chart Ref: 66, 68, 77

Capricornus is located beside Sagittarius outside the Milky Way midway to the Square of Pegasus. Looked like a double "V" - both very broad at the opening with the lower one being much deeper than the upper. Reminded me of a painted clown smile. The constellation also had many stars inside of it. Will have to take a closer look through binoculars.

Thanks to Dave Chapman! He jokingly referred to this constellation as "Orion's underpants." (NOTE: Zits cartoon in 2018 referred to it as "Orion's fanny pack.")

This wasn't the first time I found the Pleaides but it was the first time it was so easily visible in the sky. I am always impressed with this beautiful open cluster!

The 7 main "sisters" and their parents were very bright with numerous stars surrounding them. It always reminds me of a shrunken Big Dipper - shorter handle (1 main star) and a smaller squared bucket.*

* Roland, an astronomy friend from out West, described the Pleiades as a "shopping cart." I like his descriptor better than my "shrunken Dipper."

Conjunction: Saturn - Mars - Antares / Venus - Jupiter with "green flash"

Location: 2016 Nova East Star Party, farmer's field near Smileys Provincial Park
Date: 2016-08-27
Time: 8:10 - 8:45 PM ADT
Equipment: Binoculars 10x30 IS + Visual
Magnification: x10
Seeing: very good
Transparency: very good

Dr. Roy Bishop had organized with a local farmer to use the farmer's driveway and adjacent field for viewing. A group attending Nova East drove 5 minutes outside Smiley's Provincial Park to the farm with a direct view facing West.

A partly cloudy sky with wide expanses of clear sky. Warm evening with the sky at the horizon in beautiful orange/peach shades. South of the sunset were Saturn with Mars (@ 7 o'clock to Saturn) and Antares (directly below Saturn and @ 5 o'clock to Mars). The two planets and star were extremely bright and other deep-sky objects also shone brightly (I didn't observe the DSOs).


Venus and Jupiter were visible then briefly covered by clouds before coming back into glorious view. Venus was exceptionally bright and positioned almost directly above a smaller and less bright Jupiter. We watched as the two planets lowered into the horizon - first Jupiter, then Venus. Gem of the night was seeing the ever so brief green flash of Venus at the horizon.

Melotte 111 / Coma Star Cluster
Time: 10:50 PM ADT
S&T Chart Reference: 45
Instrument: Visual + Binoculars
Coma Star Cluster is easily seen as a large rectangular-like cluster of stars below α and γ. Visually, there appeared to be areas/spots of light in the elongated box closer to γ. In binoculars, there were numerous very bright stars in my FOV, all spread apart. It certainly was an open cluster and large enough it wouldn't fit in a single FOV! Really beautiful. Almost as striking as the northern Pleiades.

Time: 8:35 PM AST start time; end time unknown  
Equipment: Visual
Magnification: n/a
Seeing: very good
Transparency: very good

-6° C, clear skies. An amazing clear night! With seeing so well, I wanted to determine which of the stars in the constellation could be seen naked eye. Didn't look for M35 at the end of Castor's foot. Couldn't make out the "arms" but the legs were seen after several seconds of looking and blinking (Mebsuta, η (eta), δ (delta), μ (Mu), Mekbuta, ζ (Zeta), and Alhera). 

Binoculars confused me because of all the other stars also visible, so I  didn't spend any time using them.

Clear with occasional clouds. 12° C, humid with little or no wind. I attended Tony Schellinck's binocular table and found quite few objects.

M31 (Andromeda Galaxy)
First up was finding Andromeda. By finding Cassiopeia, we used the arrow of the larger 1/2 "W" to find the constellation. He also showed us how to find it using the Square of Pegasus, going over two lines of stars, then going up the 2nd line to the 3rd "star" that's was kind of fuzzy - that was Andromeda. 
   

I followed Tony's directions to find Cygnus naked eye, then the directions on how to locate Albireo - the double star that I could see had a yellow-gold component and the other was blue.

   

Tony's directions to find the Coathanger:
Locate Deneb, go down the neck of the swan (Cygnus) to Albireo. The Coathanger (aka Collander 399) is ~ 1.5 FOV from Albireo. By going down about 45° from Albireo, we would come down to an upside-down coathanger. This was really cool! It was very easy to see the upside-down hanger - 6 stars forming the straight line of the hanger with 4 stars forming the hook that curved towards the right. It was slanted at about 40° angle in the FOV. The hook began at the 4th star from the left. Thanks, Tony Schellinck!

He also showed us to find Vega in Lyra and the double-double of Lyra1  Epsilon and Lyra2 Epsilon.

Going towards the south end of the Milky Way, he pointed out Serpens, Scorpius and Sagittarius. After explaining two types of star clusters (globular & open) and nebula, he showed us how to find M8, M17, M22 and M25 in Scorpius along with M16 in Serpens and M6 & M7 in Scorpius.

M6 (Butterfly Nebula):
Time: 9:48 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Ref Chart: 56, 58, 67, 69, J

The grey smudge appeared and was easily viewed. There are two ways to find M6:
   a) Find Kaus Australis in the Teapot. Go to the right 1 FOV. Put that point on left of FOV and go right for 1/2 FOV. M6 should be in the middle of your view. 
   b) Take the distance from Theta (θ) to Kaus Media. Following the same direction, go 1.5 times that distance from Kaus Media.

Sketch of M6 can be found at Messier Catalogue - M006 (Butterfly Cluster / NGC 6405) - August 14, 2015


M7: (Ptolemy Cluster, NGC 6475)
Time: 9:48 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Ref Chart: 58, 67, 69, I
Follow the base of the Teapot out 1.5 FOV from Kaus Australis. Large bright open cluster easily seen visually and very bright in binoculars. Multiple stars seen in FOV, some brighter than others.

Sketch of M7 can be found at Messier Catalogue - M007 (NGC 6475) - August 14, 2015

 

M13 (Hercules Cluster)
Time: 9:45 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Ref Chart: 52, 54
This was my 1st finding of M13. Tony Schellinck said to locate Corona Borealis to locate the Keystone of Hercules. M13 is located on the western side, approximately 1/3 of the way between Eta Hercules and Zeta Hercules. NOTE: Following the curve of the Corona also points to M13.



M16 (Eagle Nebula), M17 (Swan Nebula) &
M25 (IC 4725):
Time: 11:23 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Ref Chart: 67, I
All 3 were greyish smudges in the sky.

   To find M16: Start at the Teapot spout, follow the line from Kaus Australis to Kaus Media. Following in same direction, go up 2 FOV to M16.
   To Find M17: Should see M17 in same FOV as M16.
   To Find M25: Following the direction of the line between Kaus Media and Kaus Borealis, go 1.5 FOV above Kaus Borealis.

M22:
Time: 9:55 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Ref Chart: 67, 69, I
Find the tip of the Teapot lid (Kaus Borealis).
Go left of it ~ 30° to a Y-shaped group of stars. Left of this is M22. I was able to find the object using Tony's technique.


                                     

Delphinus:
Time: 10:15 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Ref Chart: 64
To find: Locate Altair. Go about 45º up and to the left.
All stars in the constellation were visible and easily found from Altair as the orienting star. fairly small constellation. The 4 stars in the rectangle form an asterism called "Job's Coffin".

 

 

 Lyra:
Time: 10:35 PM ADT
Equipment: Binoculars 10x30 IS
S&T Ref Chart: 63
To find: Tony told us to locate Vega then find the 2 stars that form a triangle with Vega. Double stars are on the top left of the Triangle - ε1 and ε2. These stars are also doubles themselves but cold not make that out in binoculars.

Used the Teapot in Sagittarius to find M6 (thanks to the directions provided by Tony Schellinck).

Started at Kaus Australis then went west 1 FOV. I put that point on the left at 9 o'clock then went west 1/2 FOV. M6 was centred in my binoculars. The grey smudge was easily identified and a few bright areas/stars were seen. There seemed to be a row of 4 stars near one border, a row of 3 stars below it, and a triangle of stars below that.

Tony Schellinck was teaching us how to star hop using our binoculars at Nova East Star Party.

I found M6 then went 45º to the right. The open cluster appeared with a few bright stars within it. Could also locate this visually by going east from Kaus Australis in the Teapot. What was especially noticeable was the line of 4 stars.

We had heard the Aurora Borealis would be visible from the northern shores of our province so we headed to Hall's Harbour on the Fundy Shore.

Jerry set up his equipment for time-lapse as the colours would not be seen from our latitude. We couldn't see the vibrant colours but we could see the undulating pale cream bands on the northern horizon. They varied in brightness, height and distance from us. We were very excited to see the Aurora despite it being colourless. Our daughter and son-in-law who resided in Kentville area brought hot chocolate to us on the beach - very much appreciated!! The light on the pier did have some effect on the visibility.

NOTE: I did see a red-green Aurora while camping at Lake Superior Provincial Park in mid-July 1987. My brother and I sat up until the wee hours of the morning chatting and saw them overhead.

My first Star Party!  Hubby found the RASC Halifax Centre Nova East Star Party online and was interested in going. After initially saying no to going with him, I changed my mind - after all, it was a camping weekend. On Saturday morning, there was a session that was well beyond my comprehension so I went to the observing field to listen to Paul Heath's Walk the Solar System. Along with the children in attendance, I learned a lot! Later that evening, Paul pointed out constellations and special stars in his Sky Tour. This was followed by Tony Schellinck's Binocular Table at which participants were given a pair of binoculars and showed several constellations, their special stars and the Messier targets in them. It was because of these two gentlemen that I was hooked on astronomy!!

Unfortunately, I did not begin to 'officially' log my observations until August 2015 after much coaxing from Melody Hamilton.
