MDM Observatory 1.3m Telescope Observing Report for 2011 Jun 28 Observer(s): Halpern Institution(s): Columbia Instrument: Templeton Worked for 6.5 hours (off and on through the night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Clouds all night. Beg: Seeing 1.5 arcsec, Cirrus, Winds Light & Variable Mid: Overcast, Winds Light & Variable End: Seeing 1.5 arcsec, Cirrus, Winds Light & Variable Observing Summary: Liquid nitrogen surgical tube has a leak. Should be replaced. Sometimes telescope dithers N-S, sometimes not. But it NEVER completes a slew. Tracking turns off in the middle, and it takes 3-4 rounds of this to get to the targets position. ------------------------------ Submitted on 2011 Jun 29 [5:08:48]
