Observation 1: Moon Phase: Waxing Gibbous (81.5%) R1: Gassendi was easily found on the north shore of Mare Humorum. It appeared to have 3 central peaks. Gassendi A & B also visible. Crater A appeared to have a tall crater wall that created a large shadow on the floor whereas crater B appeared shallow by comparison. C1: The rilles were in greater number on the west side and almost suggested 2 or 3 craters in the past with varying depths. |

Observation 2: R1: Observed mini-craters on Gassendi's floor plus one on its west wall. Looked like the "time" was 4:40 PM. I didn't take the time to sketch this in detail. |
