              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Night started with no chance of opening.  Lots of graupel -like snow, about 2 inches by 19:00. Forgot that snow means snow program, did not start snow program until 20:30.  Ran it manually, due to the frequent power outtages. The snow stopped for a while, but started again heavily at 04:00. We did not open at any point in the night.
Due to the very low winds, which died down after 22:00 there will be snow accululation on the roof despite regularly turning the dome.  The dome has been left at az=0.
