APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday February 19, 2026 (SJD 61091) ---- Observing Team ---- Conner Scoresby ---- Observing Plan ---- Thu 19 Feb 2026 61091 0.09 01:46 02:00 12:33 04:57 15:31 --- dark (10.5 h) plus 0.2 h for 12 deg design ---- Observing Summary ---- Inefficient night, between clouds, wind, and humidity changing hands often. We were either closed or not observing for the majority of the night. Of the eight designs observed, six were completed, and zero epochs were completed. Notes: 1. Collision reported on 102042-754222-24816 with robot 650 on reverse at 05:49Z. Three explodes and unwinds restored the array. 2.Dust collected ~8000 dust-hours ---- Automatic Summary ---- Time Field-Design-Conf DesignType BOSS/APOGEE Seeing Overhead Complete?
