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.

Andromeda (M31) & Cassiopeia 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 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! |

Hercules, Keystone of Hercules & M13 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). |
