MDM Observatory 2.4m Telescope Observing Report for 2011 Mar 23 Observer(s): John Thorstensen Institution(s): Dartmouth Instrument: Nellie direct; retrocam Worked for 10 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+ arcsec, Clear, Winds Moderate Mid: Seeing 1+ arcsec, Clear, Winds Moderate End: Seeing 1+ arcsec, Clear, Winds Moderate Observing Summary: Good clear night, with mostly OK seeing (but not excellent). But, in the middle of the night, the CCD system stopped working, so I frittered away the rest of the time with Retrocam doing various stuff. ------------------------------ Submitted on 2011 Mar 24 [6:05:51]
