MDM Observatory 2.4m Telescope Observing Report for 2024 Jan 08 Observer(s): M. Sitaram, D. Schiminovich Institution(s): Columbia University Instrument: CHaS Worked for 4 hours (first half 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 Calm Mid: Clear, Winds Calm End: Clear, Winds Calm Observing Summary: Clear weather. Lost 1.5-2 hours in the beginning of the night because mirror covers did not open when commanded from GUI -- eventually with Eric's help we managed to open them. Collected ~4 hours of data before there was a failure of the HA smart motor encoder causing the telescope to slew to the horizon limit and ending observing for the night (problem detailed in trouble report). ------------------------------ Submitted on 2024 Jan 10 [6:37:34]
