              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Ice on the lightning arrestors on the top of the 3.5m enclosure made it unsafe to open tonight.  Humidity was high until around 01:30 and the wind gusts then picked up to over 40MPH.
I did instrument fills around 04:45AM.
Telescope parked due South to melt any remaining ice/snow on the enclosure.  I left the telescope parked at alt 75 in case Bill wanted to run the snow program during the day to help get rid of the ice on the lightning arrestors.  It will need to be returned to the normal park position at some point so we can get LN2 into the enclosure.
