Observing Specialist: J.Dembicky
We were closed due to snow tonight.  3 inches of the white powder at around 16:00. 6" or so around 23:00.
I taught Dan O. how to use the walk behind snow blower tonight.
I noticed that the MacMini driving the IR and visible camera displays was making some fan noise tonight.  One of the other obs specs also mentioned this at our last obs spec phone con. PR Submitted
I left the telescope parked due south.  Snow will need to be removed from the enclosure.  I cleaned the snow off the catwalk outside.
