              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
High humidity at sunset, then snow very shortly after.  Slewed the scope to the south due to the weather.  Snow tapered off around midnight, but what had fallen continued to be blown around. In addition, we had very high humidity.
Snow stopped blowing around 02:00.  Snow started again around 05:00, and we called it a night at 5:20, no hope of opening.
Left scope pointing due south due to snow.  Total accumulation on the ground appears to be a little over an inch.
