              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
No hope of opening tonight due to the snow storm. We received about 4-5 inches of snow, which was heaviest during A half. Winds gusted near 40 mph. There were some power flickers during the afternoon so the mirror covers did need a reset. Things definitely don't look promising for the next few nights.
I ran the snow program all night and parked the dome south.
