MDM Observatory 2.4m Telescope Observer's Report for 2008 Sep 13 Observer(s): Yee and Stoll Institution(s): OSU Instrument: TIFKAM Worked for 10 hours (all night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1 arcsec, Clear, Winds Calm Mid: Clear, Winds Light & Variable End: Clear, Winds Light & Variable Observing Summary: A good night. Good seeing, lots of data, a bit hazy. The only trouble was when the telescope lost guiding once, drifting in the middle of one exposure. This happened concurrent with a warning about the dec encoders. The erroneous motion stopped on its own within about ten seconds. ------------------------------ Submitted on 2008 Sep 14 [5:49:49]
