MDM Observatory 2.4m Telescope Observing Report for 2012 Feb 22 Observer(s): Kay et al. Institution(s): Columbia Instrument: Mk III + Nellie + 600/5800 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 2 arcsec, Clear, Winds Calm Mid: Seeing 1 arcsec, Clear, Winds Light & Variable End: Seeing 1 arcsec, Clear, Winds Light & Variable Observing Summary: Very clear tonight, possibly photometric (we'll see at twilight). Seeing started out ok (~ 2 ) but by midnight or so was much better, so we worked with the 1.17 slit. Minor issue with the instrument rotator -- it wouldn't work. Power cycling fixed the problem. We only lost a little time. ------------------------------ Submitted on 2012 Feb 23 [5:27:48]
