APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday April 30, 2009 (MJD 54952) ---=== OBSERVING TEAM ===--- Audrey Simmons Howard Brewington Support: Steph Snedden and Dan Long ---=== OBSERVING PLAN ===--- SEGUE2 Science! ---=== OBSERVING SUMMARY ===--- We had a loadCart problem during the afternoon checkout. Added signal to: Cart 04, plate 3328 Cart 08, plate 3368 Cart 05, plate 3386 DONE An FK5 was used to find each field, and spiralPattern was needed on two of the fields. We may need a new pointing model. The spectro dewars is getting low. ---=== OBSERVING LOG ===--- Afternoon: ---------- 22:50Z I replaced a couple of lamps in the 2.5-meter control_room. 23:00Z Started the afternoon checkout. 23:15Z Completed the apo_plotbias; results posted in Prob Section. 23:19Z Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 118G 18G 88% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 850G 21G 98% /data sdssfiles1p:/data1/data 1.5T 657G 736G 48% /files 23:30Z Spectro focus was checked and adjusted. i.e., sp1 by 2500, and sp1 by 2000. It's set for about 13-degree C. The collimate numbers are posted in the Problem Section. 23:40Z While doing the spectro checkout, we discovered a problem with the plugMapM file for cart 05, plate 3386, yet cart 05 was still mounted on the scope from last night's observations. Today, however, it had a new plugMapM file and a new Cart_ID_number. I talked with Dan Long, and we guessed that when Cart 08 with plate 3368 was plugged and mapped today, plate_number 3386 was accidentally used. Cart 08 with plate 3368 was later remapped with the correct plate_ID; however, the bad plugMapM file for Cart 05 was, unfortunately, left in the *3386* directory. 23:45Z Mounted Cart 04. 00:40Z Started telescope checkout; doors/louvers opened, fans turned on. 01:00Z Afternoon checkout completed. 01:41Z Sunset with scattered clouds. Night: ------ 01:42Z 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. 02:07Z Cart 04, plate 3328 (Feb09a_SEGUE2). Field was found with an FK5 and spiralPattern. Seeing was ~1.0" as reported by the guider.
