              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
And here I thought it would be a nice quiet night of softly falling snow and a night in the dome with the filters.  There was no snow, just rain, and things were anything but quiet.
ecam had a strange read out pattern where half the chip was bright and half was dark.  It was fixed by a hub startnubs.
Power went out at 20:45 and we switched to generator power without issue.  However, at 23:36 we had another power issue and we lost power for a few seconds.  We lost site air for about an hour but Downton Downey came and restored everything. I parked the telescope at 85 altitude in case there should be any additional power issues while I'm asleep.  I called the power company after the second power outage and they reported there was an equipment failure that was being addressed.
