              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started partly cloudy, but with good seeing. We had borderline high winds, though. After sunset, skies cleared, and the wind died down a little. Gcam need a nub restart around midnight.
We began to get high thin clouds around 4am. There were no returns on the radar so we stayed open until light.
