MDM Observatory 2.4m Telescope Observing Report for 2017 May 15 Observer(s): Oey et al. Institution(s): Michigan Instrument: CCDS Worked for 5 hours (most of the night) Conditions were Photometric most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Clear, Winds Moderate Mid: Clear, Winds Light & Variable End: Clear, Winds Light & Variable Observing Summary: The pointing again caused major time losses, at least 1.5 hours. It was off by several arcmin in either direction. 8 arcmin at one point. The CCD warmed up significantly toward the end of the night. We prob didn't fill it enough earlier in the evening. Surprisingly the biases still looked good. ------------------------------ Submitted on 2017 May 16 [3:28:21]
