              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Despite relatively clear skies, it started snowing before sunset. Snow for most of A-half and high humidity for the rest of the night kept us closed.
I ran the snow program while it was snowing, and parked the dome at 0,20.
No telescope or instrument problems.
