HI Dave,
I admire your observational prowess, I usually do not take much of an interest in the Moon, I don't know why, but the study of the Moon and it's display at the terminator just does not do anything for me. I'm more of a deep sky fanatic, so the Moon is my observational enemy.
I have heard reports of some folks seeing flashes on the Moon possibly from minor impact events, I did want to witness the crashing of the two part space vehicle that NASA was doing looking for water, but I was told it was not so great, did you get a chance to observe it from your location?
Dennis
