              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Due to the winter storm dumping about 6" of new snow on us during the daytime, we were not able to open at all tonight.
I parked the telescope due South this morning.
It was snowing again at 04:15 but I did not see too much new accumulation, perhaps just from blowing snow on the sidewalks.
