MDM Observatory 1.3m Telescope Observer's Report for 2006 Sep 21 Observer(s): Bentz and Denney Institution(s): OSU Instrument: CCDS Worked for 7 hours (most of the night) Conditions were Mixed most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Very bad weather from 8:45 until 11:45. Beg: Seeing 2 arcsec, Fog/Low Clouds, Winds Moderate, high humidity Mid: Seeing 2 arcsec, Cirrus, Winds Moderate End: Seeing 2 arcsec, Cirrus, Winds Moderate Observing Summary: We started observing NGC 7469 at the beginning of the night again, and once again had to shut down because the humidity spiked, only this time it was accompanied by fog. We were closed for about 3 hours, after which the humidity dropped and the fog dissipated. We were able to observe the rest of the night. Also at the beginning of the night, the finder mirror would not move to the in position. I called Bob, who had me turn the belt on the finder mirror motor and jiggle the wire connections to the motor. The white plastic wire harness was slightly loose, because the motor started functioning properly after I tightened the connection. We had no more problems with the finder mirror after that. ------------------------------ Submitted on 2006 Sep 22 [5:24:53]
