MDM Observatory 2.4m Telescope Observer's Report for 2004 Feb 11 Observer(s): Matthew Walker Institution(s): Michigan Instrument: 8k Worked for 12 hours (most of the night) Conditions were Photometric most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Seeing 1 arcsec, Clear, Winds Calm Mid: Seeing 1 arcsec, Clear, Winds Calm End: Seeing 1 arcsec, Clear, Winds Calm Observing Summary: I received error messages reflecting a lack of communication with the slave power. After getting ahold of Bob Barr, we solved the problem finally by powering down the slave, then the master, then powering back up. This came at a bad time, as it prevented my taking evening twilight flats and I missed an hour of observing. It was relatively smooth sailing from then on, however. The only other glitch occurred when detcom froze up during a 20-minute exposure. Conditions were photometric all night, seeing was subarcsec ------------------------------ Submitted on 2004 Feb 12 [7:34:48]
