MDM Observatory 2.4m Telescope Observer's Report for 2008 May 30 Observer(s): Roberto Assef Institution(s): The Ohio State University Instrument: MDM 8K Worked for 10 hours (all night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1.2 arcsec, Cirrus, Winds Calm Mid: Seeing 1.8 arcsec, Clear, Winds Calm End: Seeing 1.2 arcsec, Cirrus, Winds Calm Observing Summary: Weather was relatively good. There were high altitude clouds at the beginning and end of the night and for some parts of the night. Because of this, I could not take skyflats. The seeing started being good (1.2 ), then degraded to 1.8 , started oscillating between these two values, and then settled at 1.8 . Latter, close to sunrise, the seeing was again 1.2 I had no problems during the night and I could observe the whole time. ------------------------------ Submitted on 2008 May 31 [5:16:09]
