              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Overcast skies, high humidity, and light snow that started this afternoon kept us closed for the night.
Started snow program at 23:15, when snow started accumulating; stopped at 04:25. There are only a few millimeters of (new) snow on the ground.
Parked telescope at 0, 20 due to snow and cold.
