APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday May 26, 2026 (SJD 61187) ---- Observing Team ---- Conner Scoresby ---- Observing Plan ---- Tue 26 May 2026 61187 0.85 03:04 03:22 10:38 12:38 19:54 --- bright until 09:28 ( 7.3 h, w/ 1.2 h for 8 deg design), then dark ( 1.2 h) ---- Observing Summary ---- The first half of the night was lost to radar returns all around the county. When the system finally pushed off to the east the clouds cleared with it and we opened after midnight and enjoyed good seeing. We completed 14 bright designs including during the dark time as they were scheduled. Notes: 1.
