              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Completely overcast and humid the entire night, with intermittent fog, and finally snow beginning around 03:30. We began the snow program with roof heaters around 04:30, and ran it until I went to bed around 06:00. The roof heaters are ON, and the telescope is parked facing south.
We did not open at all tonight.
