MDM Observatory 1.3m Telescope Observer's Report for 2007 Jul 21 Observer(s): armstrong; thompson Institution(s): columbia Instrument: templeton/direct Worked for 2 hours (all night) Bad weather most of the night. No equipment or software problems were encountered. Seeing and Weather: Very bad weather from 22:00 until dawn. Beg: Seeing 1.5 arcsec, Patchy Clouds, Winds Calm Mid: Overcast, Winds Light & Variable End: Patchy Clouds, Winds Calm Observing Summary: Got a little data early on in the night; then clouds moved in. Closed; reopened about an hour later, got a little more data. Closed for high humidity and increasing clouds about 30 min later (~ 11:30pm.) Soon afterward, rain began suddenly, and utterly pummelled us. Quite impressive, even before being joined by lightning soon afterwards. By then we were in lightning shutdown. After ~ 3:30 there were patches of clear sky, but I never managed to get any more usable time series. ------------------------------ Submitted on 2007 Jul 22 [6:45:32]
