Double Stars: ε1 & ε2 Lyrae; δ1 & δ2; Lyrae, ν1 & ν2 Lyrae; ω1 and & ω2 in Scorpius
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.

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 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 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 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) 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 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. |

Hercules & M13 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. |
