APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday October 23, 2025 (SJD 60972) ---- Observing Team ---- Dan Oravetz ---- Observing Plan ---- Thu 23 Oct 2025 60972 dark (10.6 h) plus 0.4 h for 12 deg design ---- Observing Summary ---- A cloudy night, leftover from last night's weather system. At times it seemed like there would be enough of a clearing to potentially warrant opening, but nothing of substance ever materialized and it just stayed cloudy, so we did not open tonight. ---- Observing Log ---- ============================================================================ AFTERNOON CHECKOUT ============================================================================ All systems alive and responsive, but alertsActor required a restart because it was stuck in the loop of complaining about a BOSS status timeout every minute or so, likely because there had been a BOSS secondary dewar pressure alarm this afternoon.
