APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday January 03, 2026 (SJD 61044) ---- Observing Team ---- Conner Scoresby ---- Observing Plan ---- Sat 03 Jan 2026 61044 0.99 01:07 01:22 12:53 01:14 12:46 --- bright (11.8 h, w/ 0.3 h for 12 deg design) ---- Observing Summary ---- The first half was sporadic and inefficient due to intermittent cloud cover. That cloud cover became an all-sky blanket by 06:00Z and signal accumulation was so poor numbers weren't being reported. Closed at 06:45Z and we didn't reopen. Completed 11 of 13 bright designs. Notes: 1. Very low dust counts tonight. ---- Automatic Summary ---- Time Field-Design-Conf DesignType BOSS/APOGEE Seeing Overhead Complete?
