              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Upon checkout, some snow was found still on the roof. Since the air temperature was above freezing, I decided to run the roof heaters to try and melt what was left. Warm air and an assist from the roof heaters took care of what was (hopefully) the last of the snow, and we opened at 20:00. Skies were mostly clear but with haze and occasional clouds. Seeing was ok, and improved after midnight. We were open for the rest of the night.
