              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland, J.Dembicky
Power went out around 1500. PM lost air for a while, but after relaxation procedure, it is fine. Dataq program was rebooted.
Start of night, weather is fine but, we are still on generator power, so we decided it's best to stay closed, both on the 3.5m and arcsat.
Opened dome around 2320 with clear weather. Dust counts started going up but the counts inside the dome were well below the limit.
No other problems with telescope.
