APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday February 20, 2026 (SJD 61092) ---- Observing Team ---- Conner Scoresby ---- Observing Plan ---- Fri 20 Feb 2026 61092 0.17 01:47 02:01 12:32 05:02 15:34 --- dark (10.5 h) plus 0.2 h for 12 deg design ---- Observing Summary ---- The first half of the night was lost to dust, then heavy clouds. They cleared up after midnight to good seeing, but that degraded slowly and steadily as the night progressed and slowing efficiency some. Completed 12 designs. Notes: 1. Dust collected ~2900 dust-hours ---- Automatic Summary ---- Time Field-Design-Conf DesignType BOSS/APOGEE Seeing Overhead Complete?
