MDM Observatory 2.4m Telescope Observing Report for 2021 Oct 27 Observer(s): Rupert Institution(s): MDM Instrument: OSMOS/B Worked for 12 hours (all night) Conditions were Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1.4 arcsec, Clear, Winds Light & Variable Mid: Seeing 1.1 arcsec, Clear, Winds Moderate End: Seeing 1.3 arcsec, Clear, Winds Moderate Observing Summary: Seeing started out sub-par. Eventually settled down for a bit. Overall it was an unstable night in the atmosphere. No doubt the driving winds were a part of it. First attempt at moving the guide probe it would not move in x using a preset and typing in a value in the x field. A power cycle of the MIS remedied this. Overall a productive start to the run. ------------------------------ Submitted on 2021 Oct 28 [5:22:29]
