APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday October 1, 2008 (MJD 54741) ---=== OBSERVING TEAM ===--- Audrey Simmons Dan Oravetz Howard Brewington (cloud cam/DIMM) ---=== OBSERVING PLAN ===--- BOSS/SEGUE Science! ---=== OBSERVING SUMMARY ===--- BOSS Imaging ------------ Imaged all of 81 N from lambda = 130 to lambda = -163 including ramps with good seeing (median seeing never more than ~1.5" as reported by seeingRun). Imaged all of 75 N from lambda = 143 to lambda = -153 including ramps with good seeing (median seeing never more than ~1.4"). SEGUE Spectroscopy ------------------ Finished cartridge 2, 3123. Declared cartridge 5, 3130 done. ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working properly. sdsshost2.apo.nmsu.edu % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 115G 21G 85% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 767G 104G 89% /data sdssfiles1:/data1/data 1.5T 717G 676G 52% /files Spectro focus not adjusted. Set for ~9C on average. 00:10Z - Began ventilation. Doors and louvers opened, fans on. 00:52Z - Sunset. Night: ----- 00:55Z - Enclosure off. Topped-off spectro dewars. The conditions seemed fit for imaging, but since we still had plenty of time in twilight to wait for the sky to darken, we decided to check the seeing with the guider and cartridge 1. Cartridge 1, 3129, segue ************************ 01:10Z - gotoField. Guide stars found on gotoField. The seeing was 1.3" according to the guide stars and 1.0" according to the DIMM. We also had photometric skies. We decided to proceed with BOSS imaging. 01:25Z - Mounted imager. Adjusted counterweights to 730. 01:37Z - On-telescope tbars-unlatched bias. Run 7711. BOSS - 81 N *********** 01:51Z - scanStripe 81 N 126. Altitude = 54.5 degrees. 01:53Z - goDrift. Run 7712. 81 N. Focus good from the very beginning (good guess, Audrey).

End ramp-down at frame 479, lambda = -163. 81 N was imaged under photometric skies (the blip on the cloud cam around 04:45Z during the imaging of 81 N was Howard clearing some test equipment) with median seeing never worse than 1.5" as reported by seeingRun; best reported median seeing was around 1". We still had enough time to completely image one of the shorter (4.2 hour) scans, so we opted for 75 N. BOSS - 75 N *********** 06:39Z - scanStripe 75 N 141. Altitude = 48 degrees. 06:40Z - goDrift.

Began ramp-down. 11:03Z - Ended ramp-down at frame 446, lambda = -153. 75 N was imaged under photometric skies with the median seeing around 1.2" during much of the scan as reported by seeingRun. The worst reported median seeing during this run was no higher than ~1.4". We had enough time before 18-degree twilight to attempt finishing cartridge 2 with one exposure (especially considering the excellent seeing). 11:05Z - Dismounted imager. Mounted corrector and cartridge 2. Adjusted counterweights to 255. Cartridge 2, 3123, segue ************************ Previous signal: (S/N)^2 = 74.5 43.3 62.9 43.3 11:13Z - gotoField.
