APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday May 11, 2026 (SJD 61172) ---- Observing Team ---- Conner Scoresby ---- Observing Plan ---- Mon 11 May 2026 61172 0.26 02:51 03:08 10:50 11:25 19:07 --- dark ( 7.7 h) plus 1.2 h for 8 deg design ---- Observing Summary ---- It was a clear, calm night---except for the pollen. Particulates were amply visible in the headlamp beam and a layer was seen on vehicles and other surfaces. We closed at 7:00Z when integrated dust counts crossed the threshold. The 0.3 micron dust counts have continued to steadily rise since. Notes: 1. Robot 932 reported a collision at checkout in which it did not move from folded when anticipated; one unwind restored it and subsequent configuration executed without complaint. 2. BOSS b1 focus ring was adjusted +7 degrees just before midnight to 58 degrees. 3. Dust collected ~10000 dust-hours + pollen particulates, request optics cleaning ---- Automatic Summary ---- Time Field-Design-Conf DesignType BOSS/APOGEE Seeing Overhead Complete?
