APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday May 27, 2009 (MJD 54979) ---=== OBSERVING TEAM ===--- Audrey Simmons Howard Brewington ---=== OBSERVING PLAN ===--- SEGUE2 Science! ---=== OBSERVING SUMMARY ===--- There seems to be a problem with the fire alarm control panel in the plug lab. The unit began to beep, and the trouble light flashed. The beeping was stopped by pressing the ack/step button. The service company should be notified. Part of the night was lost to clouds. Added signal to: Cart 02, plate 3428 DONE Cart 08, plate 3427 DONE We got a WATCHER error about the CCD temp of CCD 00, which is the PT chip. Is this chip in service? ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:00Z Started the afternoon checkout. 23:30Z Spectro focus was checked but not adjusted; it's set for about 10 degrees C. 23:52Z Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 119G 16G 89% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 739G 132G 85% /data sdssfiles1p:/data1/data 1.5T 594G 799G 43% /files 23:53Z Completed the apo_plotbias; results posted in Prob Section 01:00Z Doors opened, fans on 02:01Z Sunset Night: ------ 02:05Z Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, checked fiducial crossings for each axis, and started the DIMM. 02:29Z Cart 02, plate 3428 (April09d_SEGUE2).
