                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Clouds, snow, fog kept us closed all night. Probably 3-4 inches of
 light fluffy stuff, for the high winds to blow around, at the start of
 the night and 4-6 when we left for the night. Roof heaters were on all day
 as well as tonight.  When I checked the roof there was a little snow
 as well some ice buildup on the eves.  With gusty winds tonight I am
 guessing there won't be a lot of accumulation, but I could be wrong.
 Roof heaters were turned off as it was really was too cold for them to do
 much good as the temp plumeted after midnight to -10C.
 Hopefully during the day the temps will be warm enough to melt any
 ice/snow and the roof heaters can be turned back on.
 We did snow removal duty around 7PM as well as around 2:30AM this
 morning.  Blowing and additional snow made it kind of futile though.
