MDM Trouble Report for 2021 Nov 07 Telescope: 2.4m Observer(s): I. Cevallos Aleman, B. Cruvinel Santiago, D. Schiminovich (Columbia University) Instrument: CHaS Problem(s) Encountered: We had problems with the mirror supports (we couldn't hear the clicking sound) in the beginning of the night, which made guiding impossible. After contacting Eric, we restarted its system and were able to proceed even though we couldn't observe our first target of the night. We had to power cycle the MIS a few times during the night, since it was getting stuck in the same place from time to time. ------------------------------ Submitted on 2021 Nov 8 [5:42:52]
