Subject: 2.5m obslog 20250512 (SJD 60808) From: cscoresby@apo.nmsu.edu Date: Tue, 13 May 2025 10:31:26 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday May 12, 2025 (SJD 60808) ---- Observing Team ---- Conner Scoresby Conor Sayres (GFA bright star offsetting tests) ---- Observing Plan ---- Mon 12 May 2025 60808 1.00 02:53 03:10 10:48 11:31 19:11 Night bright ( 8.8 h, w/ 1.2 h for 8 deg design) Dithers, weather permiting ---- Observing Summary ---- We opened at sunset to partly clear skies with the hope that we would be able to get something in a clear window. While preparing for a set of BOSS dithers, the dust counts began increasing rapidly, and we had to close. The dust settled down briefly at 5:00Z, and we opened just long enough for Conor to test some bright star GFA-offsetting commands. An hour later, the dust rose precipitously again, and we closed for the rest of night, which was called at 10:20Z due to dust at 26k and still rising, a massive cloud front in from the west, and no hope for reopening. No science designs observed, and no BOSS dithers completed. Notes: 1. Dust collected ~9000 dust-hours ---- Engineering Issues ---- As a note for the record, the redIonPumpLatched warning generated again tonight. Grafana graphs show that it has corrected to appropriate levels. ---- Observing Log ---- 23:16:36 Tested actors, all systems live. APOGEE evening calibrations started. Mirror numbers taken, all within spec. Start-of-shift cherno restart completed. 23:32:57 BOSS expNum=385539, expTime= 0.0s 23:35:18 BOSS expNum=385540, expTime= 20.0s 23:38:25 BOSS expNum=385541, expTime= 4.0s 23:39:05 BOSS expNum=385542, expTime= 4.0s 23:39:48 sp1.motor.move= -1439, -1439, -1437 23:39:48 Hartmann collimate output sp1: offset: r= -1979 (Out of focus); b= 2.8 (In Focus) sp1: pred. move: spAverageMove= -1439 sp1: pred. resid: r= -540, b= -1.7, txt= OK, spTemp = 9.4 23:40:43 No focus ring adjustments made 23:40:23 BOSS expNum=385543, expTime= 4.0s 23:42:05 BOSS expNum=385544, expTime= 25.0s 23:44:48 FPS powered on.
