              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had a little snow left on the roof with concerns that it might blow down into the dome, so we operated with lower wind limits for much of the night.  During the middle of the night there was high wind and also high humidity, but we were able to re-open for part of the second half.  Everything worked well.
I parked the dome facing north to get sunshine on the back side of the dome.
