              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Wind and temperature restrictions in place tonight.  15MPH max wind and mirrors below freezing.  We got a little bit of snow this afternoon, and there was some blowing snow during the evening.
Bill's restrictions kept us closed for the entire night, the wind gusts never dropping below the 15mph max. limit.
Telescope parked in SW to melt the remaining snow on the enclosure.
