It has taken me a week to get this observing session documented so I have forgotten a lot of the details.
The primary objective of the session tonight was to see the young Crescent Moon and Venus before sunset.

| Comments | We didn’t do as much intense lunar observing as we normally do but that was because the Moon set before it got dark and we had a lot of public interaction since we were set up before it got dark and people knew we were there. We did identify Mare Crisium, Langrenous, Petavius, Cleomedes and Endymion. As it started to get darker the earthshine on the Moon looked nice. |

| Comments | I could not detect any phase in either of my binoculars but could see that part of the upper corner was missing when I observed it in Peter’s scope.
It was a lot farther from the Moon than I was looking for it. |
