              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
It snowed today and was foggy with light snow until about sunset. Then we had high humidity. After 01:00 the humidity dropped but wind gust speeds stayed above 20 mph for the rest of the night, with snow blowing around. We stayed closed.
Parked the telescope at 0, 20 because there was a little bit of snow on the roof when I looked out the hatch in the afternoon.
No telescope or instrument troubles.
