              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started out mostly cloudy with the prospect of clearing for a few hours, so we opened right at sunset. Clouds did not clear as much as forecasts promised, but we powered through it.  Humidity began to rise around 19:00.  It settled down again by 20:00, and conditions varied between partly cloud to clear through 23:00.  Shortly after 23:00 cloud bank came through.  Observer was unable to collect data, and we closed the dome so they could do cals.
It began to clear again at 00:00, and the b-half observer was able to open on time, though clouds still plagued us.  Twice the alt axis had a motor error, no moths could be found but we backed off and ran through it, no more than 5 minutes was lost.  Moth was found and cleaned during the morning fills. We stayed open until dawn.
