MDM Observatory 2.4m Telescope Observing Report for 2014 Dec 28 Observer(s): Halpern, Lucy Institution(s): Columbia Instrument: OSMOS Worked for 11 hours (all night) Conditions were Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1.5 arcsec, Clear, Winds Light & Variable Mid: Seeing 1.5 arcsec, Clear, Winds Light & Variable End: Seeing 1.2 arcsec, Cirrus, Winds Calm Observing Summary: Started two hours late due to clouds. It was almost a photometric night after that, with good seeing in the second half. There was a power outage for about 1 second, which was not long enough to start the generators, and caused no problems. At the end of the night the guide probe got stuck at X=5400 and would not go to the origin. After power cycling the MIS it went to the origin. Following instructions from Paul Martini and Eric, I will check out the filter complement in OSMOS later this afternoon. I also tried remote observing with the 1.3m, which went well. All observers except me (Halpern) are leaving at 7:45am. I will stay for two more nights providing it doesn't snow before Wednesday morning. ------------------------------ Submitted on 2014 Dec 29 [7:10:33]
