APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday October 23, 2026 (SJD 61337) ---- Observing Team ---- Dmitry Bizyaev ---- Observing Plan ---- Fri 23 Oct 2026 61337 0.95 01:14 01:29 12:06 20:35 07:14 Night bright until 11:36 (10.4 h, w/ 0.2 h for 12 deg design), then dark ( 0.5 h) ---- Observing Summary ---- The entire night was lost to a storm system with thunders, lightnings, and wavels of heavy rain. When I checked telescope in the morning, the eastern door's motor made a loud, high-pitch sound that I never heard before. I opened the rolling door by a foot and then closed, and the sound disappeared. It might be a moisture related problem. ---- Observing Log ---- Afternoon ========= All systems checked, no problems identified.
