Subject: 2.5m obslog 20230918 (SJD 60206) From: dmbiz@apo.nmsu.edu Date: Tue, 19 Sep 2023 12:12:54 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday September 18, 2023 (SJD 60206) ---- Observing Team ---- Dmitry Bizyaev Conner Scoresby Kaike Pan (remote, making fiducial tables) ---- Observing Plan ---- Checking pointing, update instrumental block, check fiducials, pointing model, collect AZ fiducials. Mon 18 Sep 2023 60206 0.16 01:58 02:13 11:41 19:01 04:30 --- dark ( 9.5 h) plus 0.2 h for 12 deg design ---- Observing Summary ---- Productive night. Clear at the beginning and after 9 UT. Cloudy in between. The seeing was variable. - We figured out the calib offset that brings stars close to the center of CCD: -0.01, -0.03 in degrees (-00:00:36, -00:02:13). - with this offset we took grid and ring data, and updated the instrumental block. - we took AZ fiducial data. Kaike issued new version of fiducial tables. - we collected data for 155-star pointing model. It is too late to analyze, postponed the analysis until the next night. - by David Nidever's request, we took a FPI exposure with gang connector in the SparsePak port. - We noticed that the noise in both b1 and r1 boss biases is very high. Kaike and Jose were notified. ---- Engineering Issues ---- We took test BOSS biases, but they have very high noise (now 70-100, was 3-5). The images are uniform. Notified Jose. ---- Observing Log ---- Afternoon --------- Checked systems that supposed to be alive. Restarted alerts actor since it brought up sound alert every few seconds. It accompanied with appearance and disappearance of BOSS phase boot alert, same often. After restarting the transient alert came off. The warning is still on: camCheck.SP1RedIonPumpLatched at 2023-09-19 00:11:44 UT found 'Reported by camCheck' Turned on Ecamera. wPositions = 423 425 444 443; MCP instr = 19 (mounted); ---------- motorPosition sp1: 25001, 25000, 24999; ---------- Median spectrographs temperatures: Tsp1= 10.0 Outside air temperature= 0.0; ---------- Boss CCD Temp : sp1r0= -124.6 (-126.6); sp1b2= -99.6 (-100.0); sp1LN2: 10.0; ---------- ecameraTemp= -35.0 (-40.0) ecamera simulating = False Rel.

Tried to restart guider actor and ecamera, but it didn't help. Called Jose. He found that the flat images have some saturated pixels. We took flat in the dark conditions, and it fixed the problem. We tried to find stars, but they were not coming to the field. We pointed at a 5-mag star and took a 30-sec exposure. It showed a glog at one side of the chip. By applying calib offsets (tcc offset calib rel_az_deg, rel_alt_deg) we centered the bright star. Then tried several other stars at different locations in the sky. All they come to the center.
