              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We got a few inches of snow during the early afternoon.  By sunset the sky was clear, but there was blowing snow from building roofs.  I kept the 3.5m closed for a few hours, changing the dome position relative to wind and making sure the telescope was well below freezing.  Finally the wind dropped and we were able to open to clear skies but mediocre seeing.
The sensor that normally puts temperature in the night log is down right now, but the low temperature was around 20 F.  Fortunately we had no cold-related problems; they must be waiting for the holidays to make an appearance.
