              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started cloudy with occasional drizzle. Rain went away, and it seemed to be clearing, so we tried to open. The minute we did, the skies clouded up utterly: we could not even find a star to focus on. We decided to close up again. We stayed closed for first half. By midnight, rain had returned. The rain came and went, humidity spiked and stayed high all night. We did not open again.
