              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
SNOW!!! And humidity! We got about 7" during the course of the day and early evening, after which it was just foggy and humid. Due to the late snow and wind, the roof could not be cleared and we did not open tonight. I ran the snow program all night and parked the telescope south.
No problems tonight.
