              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had high winds and blowing snow at the start of the night, although the actual precipitation had mostly stopped.  The winds got below the regular limit before midnight, but never got below the winter limit for ice on the dome, and also the humidity never dropped.
I ran the snow program for most of the night to blow snow off the roof.  We were on generator power but it was pretty steady.  Observers took the opportunity to get extra cals with ARCTIC and DIS.
