APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday January 25, 2007 (MJD 54126) ---=== OBSERVING TEAM ===--- Kaike Pan Shannon Watters Audrey Simmons Mike Harvanek (swing) Jon Brinkman (support) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Started the night with partly clear skies but snow storms on the way. We opened for 25 minutes but had to close before getting a science exposure on the first plate. We were closed for the rest of the night and took MSP imager calibration data. We had a watcher warning that the PT "LN2"/CCD was warming up (problems). ---=== OBSERVING LOG ===--- Afternoon: ---------- The 90 degree alt fiducial did not read in either direction. The 45 degree alt fiducial did not read going up. Spectro collimation was not adjusted. Details are in the Problems section. Primary mig lateral E value was off of nominal by 0.0508. A cleanupMurmur was needed this afternoon due to host2 being "accidentally powered down" earlier in the day. Nothing else to report. Night: ------ 01:25Z Cart 6, plate 2639, baotest157. Previous (S/N)^2 = 10.3. GSOGTF. T=-3.1C. Had to close because of clouds. 03:40Z Run 6681 - Taking MSP data: 03:45Z Linearity for ccd u1.

Using the tpm_TM_PMSSAvg temp from caget, the spectrographs are currently collimated for a temp of approximately -3 degrees C. PT LN2/CCD high temp: Watcher warned us of a rising temp on the PT "LN2"/CCD. French reset the cryotiger and it's working okay for now but the pressure is low. French will recharge it in the morning.
