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.
