              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Zero'ed rotator.
Clouds and humidity (and fog and a few snow flakes) kept us closed the entire night.
We had a few flurries but thing more than maybe a dusting.  We did have high humidity and fog which felt snow but didn't stick and made the outside railing a little icy.  Temps were well below freezing all night long.
I gave up at 04:50 with humidity still hovering over 92% with little sign of it dropping in the next hour.
