              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
No snow to speak of, but freezing mist, high humidity, thick clouds, and threatening radar kept us closed.  The next round of snow was looming by morning.
I parked the dome facing SSW and, based on the predicted daytime temperatures, turned on the roof heaters.
