              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Rain and storms were on the munu for the evening.  We attempted an opening, but humidity soon got the best of us. We also had an issue with the secodnary mirror which was fixed after we closed (we were open for no more than 10 minutes).  Later the humidity dropped and we opened at 23:36. The humidity teased us for several hours, broaching the closure limit, but not crossing it.    We stayed open until dawn.
