MDM Observatory 1.3m Telescope Observer's Report for 2007 Sep 20 Observer(s): Prieto Institution(s): OSU Instrument: 4k Worked for 7.5 hours (most of the night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1.0 arcsec, Patchy Clouds, Winds Calm Mid: Seeing 1.5 arcsec, Cirrus, Winds Calm End: Seeing 1.5 arcsec, Clear, Winds Calm Observing Summary: The night started out cloudy, but cleared out about 1 hour after sunset. I lost ~1-1.5 hour after openning to a rather silly confusion not realizing I had the guide probe on the center of the field. After that everything worked fine. The seeing was around 1.5 most of the night. ------------------------------ Submitted on 2007 Sep 21 [6:05:18]
