              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Snow flurries most of the night with freezing fog as well, it was a little heavier after midnight.  I ran the snow program from midnight until 5AM.  I parked the telescope facing S when I shut down at 05:00.
Maybe an inch accumulation as of 5AM but it was snowing with a large mass of precip moving our way, so there may be more in a few hours.
