APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday September 24, 2010 (MJD 55464) ---=== OBSERVING TEAM ===--- Steph Snedden Audrey Simmons Paul Harding Craig Loomis (support) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- More than half of the night was lost due to high humidity. We managed to complete a new pointing model. We ran into a few snags along the way, but we were successful. With Paul's help we tested the collimation as a function of altitude with the ecamera, but we were chased in by high humidity and did not get to finish the test. ---=== OBSERVING LOG ===--- Afternoon: ---------- Tested actors, took a few biases, turned on THAR lamp, checked out telscope, gathered mirror numbers. 00:10Z - Started ventilating. Night: ------ A few thunderclouds around at sunset. 00:49Z - Homed and relaxed the mirrors. 01:45Z - High humidity. Stopped ventilating. Mounted engineering camera. 02:41Z - Critical alert. Sp2 didn't have enough pressure to fill, so it complained. We hooked up the lines with the pressure building valve on, and it filled without any problems. 05:49Z - Humidity dropped. Started ventilating. 06:42Z - High humidity. Steopped ventilating. 07:02Z - Started ventilating. Humidity got better. 07:22Z - Opened enclosure. 07:31Z - gimg.0004.fits, fk5 in center of CCD. 07:49Z - Began 72-point pointing model, gimg.0015.fits. Needed to abort because there was no stars found on the 2nd, 3rd, and 4th points. 08:03Z - Second attempt at the pointing model. This time, we cleared the offsets beforehand. gimg.0018.fits. Axes halted after the second point - controller error. Skipped it. Calib offsets -0.0538 in az, -0.003557 in alt after 2nd point. 3rd point there was no star; the offsets were accumulating. We called Craig. 08:27Z - We aborted and pointed to a random fk5, cleared the offsets, and saw a star: gimg.0022.fits. 08:32Z - Tried again, gimg.0023.fits. Rotator aborted, cannot compute... controller error - axes halted. Skipped first star. Another problem: 08:37:48 TC01.gcam 243 guider w text="doTccFindstars processing /data/ecam/55464/gimg-0023.fits" 08:37:48 .tcc 0 tcc I PrimDesOrient=0.00,-13.67,10.53,574.80,742.37; PrimConstRMS=0.00 08:37:48 .tcc 0 tcc I SecDesOrient=1324.81,-9.00,-4.00,-58.00,37.33; SecConstRMS=0.00 08:37:48 TC01.gcam 243 guider f text="command failed: NameError("global name 'starYY' is not defined",) at /home/cloomis/devel/guiderActor/trunk/python/guiderActor/Commands/TCCCmd.py:249" 08:40Z - Pointing model routine aborted itself. Started again.

Craig fixed the problem - something wrong with the binning. 09:58Z - Finished with pointing model.
