APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday April 28, 2009 (MJD 54950) ---=== OBSERVING TEAM ===--- Audrey Simmons Howard Brewington ---=== OBSERVING PLAN ===--- SEGUE2 Science! ---=== OBSERVING SUMMARY ===--- Scattered clouds during the first half of the night with good seeing all night. Added signal to: Cart 08, plate 3303 Cart 05, plate 3377 Cart 06, plate 3387 Spectro dewar is getting low. ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:05Z Started the afternoon checkout. 23:33Z Spectro focus was checked but not adjusted. It's set for about 11-degree C, and the collimate numbers are posted in the Problem Section. 23:35Z [hjbrew@sdsshost2 notes]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 117G 18G 87% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 846G 25G 98% /data sdssfiles1p:/data1/data 1.5T 656G 737G 48% /files 23:38Z Completed the apo_plotbias; results posted in Prob Section 00:15Z Started telescope checkout; doors/louvers opened, fans turned on. 00:35Z Mounted Cart 08. 00:40Z Did the setup for ARCSAT observing. 00:45Z Afternoon checkout completed. 01:41Z Sunset with lots of clouds; we did not open. 01:48Z Dust spiked >3K; we closed the doors/louvers and turned off fans. Night: ------ 02:05Z Dust decreased; clouds started to clear. 02:15Z 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. 02:40Z Cart 08, plate 3303 (Feb09a_SEGUE2). An FK5 was used to find the field in twilight. Seeing was ~1.5" as reported by the guider.
