MDM Observatory 2.4m Telescope Observing Report for 2023 Oct 18 Observer(s): M. Sitaram and M. Messere Institution(s): Columbia University Instrument: CHaS Worked for 12 hours (all night) Conditions were Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Clear, Winds Calm Mid: Clear, Winds Calm End: Clear, Winds Calm Observing Summary: Another great night of observing. Good weather, and telescope and instrument performed well. We collected data on three galaxy targets as well as darks and sky flats for future calibration. Dome tracking failed once when we pointed the telescope southeast (which is where it failed 2 other times in earlier nights), but was fixed by re-homing and power cycling. ------------------------------ Submitted on 2023 Oct 19 [6:46:28]
