              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Started out mostly clear. Clouds rolled in around 20:00, by 20:48 it was too cloudy to collect data, and the humidity was getting very high, so we closed.
Humidity conituned to rise, becoming fog by 02:30, and high winds began to plague us as well.  The last observer called it quits at 04:45. There was no snow per se, and to assist the Apollo team, the scope was parked at 104,80.
