MDM Observatory 1.3m Telescope Observing Report for 2012 Jun 21 Observer(s): Jules Halpern Institution(s): Columbia U. Instrument: Templeton Worked for 9 hours (all night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 2 arcsec, Clear, Winds Light & Variable Mid: Seeing 1.8 arcsec, Clear, Winds Light & Variable End: Seeing 1.2 arcsec, Clear, Winds Light & Variable Observing Summary: An excellent night, with only a slight haze at the start. There was only one tense moment when, during a sky flat, the shutter failed to open all the way. I thought I was finished for the night, but the next exposure was fine, as were the rest of the approximately 1700 exposures that I took. As there will be an instrument change, templeton was not filled. ------------------------------ Submitted on 2012 Jun 22 [5:15:53]
