APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday October 02, 2026 (SJD 61316) ---- Observing Team ---- Dmitry Bizyaev ---- Observing Plan ---- Fri 02 Oct 2026 61316 0.53 01:39 01:53 11:51 19:37 05:36 --- dark until 05:22 ( 3.5 h), then bright ( 6.7 h, w/ 0.2 h for 12 deg design) ---- Observing Summary ---- The entire night was lost mostly due to cloudy sky, rain drops, and high humidity. Even if we had no hardware problems, telescope wouldn't be open, so I assign all lost time to the weather conditions. ---- Observing Log ---- Afternoon ========= The telescope is out of order because of the slip detector power supply problem. All other systems are found working as expected.
