              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Given I wasn't sure we were even going to open tonight given the wind forecast, I was pleasantly surprised that we were open all night!! APOLLO started firing looking for the new retroreflector on the moon, the class got a lot of practice with all kinds of observing (mostly in fast panic mode), and UW10 was able to go to near dawn.  The skies were clear even if the seeing wasn't as great.
No problems tonight.
