APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday May 28, 2026 (SJD 61189) ---- Observing Team ---- Conner Scoresby ---- Observing Plan ---- Thu 28 May 2026 61189 0.96 03:06 03:24 10:36 12:47 20:01 Day bright ( 8.4 h, w/ 1.2 h for 8 deg design) ---- Observing Summary ---- There was never much hope for opening. We had some good rainfall on sight in the evening, and we had heavy radar and cloud cover the entire night. Notes: 1. The IEB was found in the same non-communication state as yesterday afternoon, but a simple power-cycle restored it to its proper function. ---- Observing Log ---- 00:24Z Tested actors, all systems live. APOGEE evening calibrations started. Mirror numbers taken, all within spec. The IEB was found in a non-communication state again. It was power-cycled, and is now communicating normally. 00:26:54 BOSS expNum=401862, expTime= 0.0s 00:28:22 BOSS expNum=401863, expTime= 20.0s 00:30:08 BOSS expNum=401864, expTime= 4.0s 00:30:48 BOSS expNum=401865, expTime= 4.0s 00:31:29 sp1.motor.move= -302, -304, -302 00:31:29 Hartmann collimate output sp1: offset: r= -989 (In Focus); b= -1.2 (In Focus) sp1: pred. move: spAverageMove= -302 sp1: pred. resid: r= -687, b= -2.2, txt= OK, spTemp = 7.9 00:32:00 BOSS expNum=401866, expTime= 4.0s 00:33:53 BOSS expNum=401867, expTime= 25.0s 00:35Z FPS powered on.
