              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
At checkout, gcam needed startNubs + init.
We had nearby radar for the first half of the night, high humidity and wind for most of the night (with gusts over 50mph). These on top of extra closure limitations due to snow left on the roof kept us closed all night.
ARCSAT software had to be restarted at the beginning of the night due to a Microsoft Visual C++ Runtime Library Runtime Error for abnormal program termination when we tried to set the camera temperature to -20 instead of -10, which also caused Maxim to spontaneously combust. After restarting everything worked fine.
