              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We got a couple hours in before the clouds came.  About 1/4-1/2 inch of snow.  I ran the snow program all night and parked the telescope due south.  Outside temps way too low for the roof heaters to be of any use so I kept them off all night.  Sunshine should melt the snow on the roof during the daytime (if the fog/humidity/clouds go away).
I shut down around 03:30AM since there was little chance we were going to be opening during the remainder of the night.
Looks like we will have a white Christmas up here at APO this year with last nights snow.
Merry Christmas to all!
