APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday April 16, 2026 (SJD 61147) ---- Observing Team ---- Conner Scoresby ---- Observing Plan ---- Thu 16 Apr 2026 61147 0.00 02:29 02:45 11:20 09:22 17:59 --- dark ( 8.6 h) plus 1.1 h for 8 deg design ---- Observing Summary ---- The night started out clear and efficient, but clouds complicated things up a bit for most of the night. There was a period of time where the only observable designs all happened to be right at zenith which increased overheads a bit. The clouds blocked all starlight from 7:00Z to about 10:00Z. Completed 14 designs. Notes: 1. Dust collected ~10500 dust-hours ---- Automatic Summary ---- Time Field-Design-Conf DesignType BOSS/APOGEE Seeing Overhead Complete?
