Although moonset wasn’t until near midnight, the Moon disappeared from our view by 9:30 PM due to our southerly treeline. I knew I had a limited window to see the Moon before it disappeared.

My focus was on the NE portion, especially Montes Caucasus. Identified Calippus and noted 3 small volcanic-looking cones SE of the range. Also noted a line of brightness in the floor of Mare Serenitatis; identified it as Dorsa Smirnov.

I then went southward to Mare Tranquilitatis where I found a familiar pattern of craters near its chores in the SW – Manners, Ritter, Sabine & Dionysius.

Rimae Hypatia was also identified but I didn’t look at it in detail.
