Subject: 2.5m obslog 20210804 (SJD 59431) From: doravetz@apo.nmsu.edu Date: Thu, 5 Aug 2021 11:39:12 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday August 04, 2021 (SJD 59431) ---- Observing Team ---- Karen Kinemuchi Dan Oravetz Katie Grabowski Kaike Pan Steve Smee Robert Barkhouser Aidan Gray ---- Observing Plan ---- FSC work. Finish up optical collimation, if weather permits. ---- Observing Summary ---- About half the night was lost to high humidty, some clouds, and nearby radar returns. We worked with the FSC and FSC instrument block data the rest of the night. The counterweights are at ~510. We rsync-ed FSC images to /home/observer/fsc/59431 on sdss-hub. An 'fsccam' instrument block file was created. We determined the location of the telescope axis of rotation on the FSC and then began adjusting the FSC deck to align its center with the axis of rotation. The best focus was at Sec Orient piston = 3972.88 um. Kaike updated the 'fsccam' instrument block file to have Inst_Foc set to 4000 um. Also, for the time being we updated the default.dat file with Xtilt=35" and Ytilt=12" and the on-axis donuts actually looked quite good. The best focus FWHM was ~1" FWHM. (We made a back-up copy of default.dat so we can revert to the all 0's SETMIR if we want to.) ---- Observing Log ---- 23:03Z Radar approaching, cloudy on site. 23:30Z Rain on site. AFTERNOON CHECKOUT: =================== 23:50Z FSC is mounted but not fully connected yet. Absorbent pads and socks are down against the west door. 23:56Z Mirror numbers are out. If we open to do optical collimation, we will home/relax the mirrors and set the mirror numbers. Telescope ready. NIGHT: ====== 04:33Z Rebalanced the telescope. Counterweights are at ~510. Starting home/relax procedure. For M1, homing E, F.

Took some test images with the FSC to verify aliveness. We created a directory on sdss-hub at /home/observer/fsc/ to house the FSC images -- we rsync them over from the FSC computer. 07:08Z - Began ventilation. Humidity improved and the nearby radar seems to be moving away. 07:48:58 - encl25m : open; We worked with the FSC and FSC instrument block data the rest of the night. The counterweights are at ~510.
