MDM Observatory 2.4m Telescope Observer's Report for 2007 Apr 24 Observer(s): Mangala Sharma & Tom Statler Institution(s): Ohio Univ Instrument: 8k CCD Camera Worked for 9.5 hours (all night) Conditions were Photometric most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Seeing 1.2 arcsec, Clear, Winds Light & Variable Mid: Seeing 1.4 arcsec, Clear, Winds Calm End: Seeing 2 arcsec, Clear, Winds Calm Observing Summary: Imaged 3 galaxy groups and photometric standards on this photometric night (finally!). The transparency was not great, and seeing varied from about 1.2 to 2 arcsec, but the clouds kept away. Telescope and camera behaved well, except for a minor problem with moving the filter wheel (described in trouble report). Bob and Steven did a good job fixing the CCD controller communications problems. (We wish the guide cameras had bigger fields of view than their current 2' x 2'.5.) ------------------------------ Submitted on 2007 Apr 25 [5:55:52]
