              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
During checkout I zeroed the rotator, which was off by only -0.03 deg. I also moved the rotator via talk2boxes and everything moved fine.
There was no hope in opening tonight given the high winds (60 mph), dense clouds, light snow, and then just freezing fog for the rest of the night.
No problems tonight.
