              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend&C.Gray
Radar and overcast all night, snow started falling around 23:30. When the snow stopped the humidity/fog came in. We were never able to open.
I ran the snow program from about midnight until 04:30 am, as snow is visible on the dome roof. Dome is parked south in case we get some sun today and not just more snow!
