MDM Observatory 1.3m Telescope Observing Report for 2019 May 14 Observer(s): Stephanie Hamilton Institution(s): University of Michigan Instrument: 4k imager Worked for 4.5 hours (all night) Conditions were Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 2 arcsec, Clear, Winds Calm Mid: Seeing 2 arcsec, Clear, Winds Calm End: Clear, Winds Calm Observing Summary: Smooth observing tonight. We again encountered the issue with data writing becoming frozen. See the trouble report for May 13, 2019. The data writing issue occurred at the beginning of the night during flatfields. After that, we made sure not to touch JSkyCalc until readout/writing was done and didn't encounter the issue again. Unsure whether correlation or causation. ------------------------------ Submitted on 2019 May 15 [2:11:51]
