              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden
Snow falling in the afternoon.  Ran the snow program at about 16:30. Checked the roof, there is lots of snow and some ice.  Ice on the very top of the lightning rods.  Should the snow miraculously stop, I'll check the roof again.
Snow did stop, and the clouds cleared for a little while.  But there are icecicles on the roof and still lots of snow (no wind to blow it off).
Stopped snow program at 05:15 and left telescope parked pointing south, alt=75 deg.  Towards the morning, there was some blowing snow and perhaps a few flurries.  Sidewalks and site roads a bit slick.
