MDM Observatory 2.4m Telescope Observing Report for 2013 May 15 Observer(s): McGraw Institution(s): Ohio University Instrument: CCDS Worked for 8 hours (all night) Conditions were Non-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 1.5 arcsec, Clear, Winds Light & Variable End: Seeing 2.0 arcsec, Clear, Winds Light & Variable Observing Summary: Overall a good, clear observing night. At the beginning of the night at 7:55 pm, I had the telescope pointed at Dec of + 36 degrees and hour angle -2:15. The TCS monitor displayed a message 'Dec Encoder not Responding', and I could not move or focus the telescope with the hand paddle. Fortunately, this only lasted a few minutes, then it started working again. This issue did not occur again during the night. ------------------------------ Submitted on 2013 May 16 [4:30:40]
