              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started as we were on generator power. The mirror covers and the enclosure motors needed restarting. The telescope was aimed due south, and the roof was checked for ice (none seen).
Utility power came back on at 16:52.  We were able to get on-sky at 17:28.  It was clear and cold.  Winds kicked up some dust, it was borderline, but did not force a close. UW01 gave their last hour to AD02, so AD02 started at 22:04. We staryed open through the dawn.
