              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Thundersnow greeted us on checkout. We had about an inch or 2 some of it melting before sunset. It was followed by high humidity through the night.  I ran the roof heaters until the temps fell below 30F.  Around 3:40 we tried to open (the humidity was borderline), but there was ice still on the roof, which fell into the dome (fortunately mirror covers were closed and the telescope was at low altitude=10 degrees).  Decided it was not worth the risk of more ice falling, and closed for the night.  The scope was left parked at (0,10) to facilitate the sun in melting the ice.
