APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday January 26, 2026 (SJD 61067) ---- Observing Team ---- Dan Oravetz ---- Observing Plan ---- Mon 26 Jan 2026 61067 bright until 08:57 (7.5 h, w/ 0.2 h for 12 deg design), then dark (3.9 h) ---- Observing Summary ---- On generator power still tonight, so we did not open. There were clouds as well, so that's a sort of consolation. During checkout, GFA3 did not want to connect and required a 'reconnect --force' to get it connected. ---- Observing Log ---- ============================================================================ AFTERNOON CHECKOUT ============================================================================ All systems alive and responsive.
