              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
No observations tonight due to heavy fog and light snow all night long. Ran snow program for most of the night; around 4 AM the snow had mostly stopped and we parked the telescope facing south for sunlight to hit the catwalk. Snow accumulation was a half inch at most.
No other problems tonight.
