              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Woke up to a winter wonderland. Bit of a surprise, as it had not been forecasted. Snow program was started after checkout (There was about 1-2 inches of snow on roof of dome). Snow fell until around 21:00, then high humidity afterwards. Another bout of snow hit around 22:00, then back to fog/high humidity. We did not open. Snow program was stopped at 05:30 and the scope was left parked at (0,10).
