APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday May 19, 2009 (MJD 54971) ---=== OBSERVING TEAM ===--- Howard Brewington Steph Snedden ---=== OBSERVING PLAN ===--- SEGUE2 Science! ---=== OBSERVING SUMMARY ===--- Battled clouds all night, but managed to finish one plate. We also got a little signal on another plate between clouds. Plate 3407 - DONE Plate 3426 - Not done yet. Plate 3426's plug map file has no guide star magnitudes, so our efficiency meter won't work with this plate. We accumulated about 28K dust-hours tonight. Please check the mirror. ---=== OBSERVING LOG ===--- Afternoon: ----------- 22:50Z Started the afternoon checkout. 23:15 Prepared ARCSAT for observations, and contacted the observers. 23:20Z Started the spectro collimation check. 23:33Z Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 118G 17G 88% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 753G 118G 87% /data sdssfiles1p:/data1/data 1.5T 609G 784G 44% /files 23:35Z Completed the apo_plotbias; results posted in Prob Section 23:48Z Started telescope checkout. 01:01Z - Started ventilation 01:56 Sunset Night: ------- Delayed opening because of clouds. Note to observers - the mcp_fiducials are now safely checked in to the svn repository. We are using v1_80 with the new pointing model. 03:32Z Twilight end 06:21Z - Opened to partly cloudy skies Cartridge 6, plate 3407 - SEGUE2 Mar 09c ---------------------------------------- 06:40Z GSOGTF Efficiency was low because of clouds, so we waited about 20 minutes before we were able to start a science exposure. Poor seeing and clouds hampered efficiency, but some useful signal was obtained in two thirty minute exposures. A third 30-minute exposure was bad. After waiting on clouds another 20 minutes, we started a fourth exposure, which was enought to declare the plate DONE ---- logfile-54970.html ---- ---- logfile-54971.html ---- --------------------------------------------------- MJD b1 r1 b2 r2 Texp Sum --------------------------------------------------- 54970 9.7 6.7 11.7 6.6 1800.0 34.7 54970 7.8 6.0 9.8 5.2 1800.0 28.8 54970 6.8 5.3 8.9 4.1 1800.0 25.1 54970 5.8 5.4 8.6 4.4 1800.0 24.2 54971 6.3 4.9 7.9 4.5 1800.0 23.6 54971 3.5 2.6 4.6 2.2 1800.0 12.9 54971 1.2 0.8 1.7 0.7 1800.0 4.4 54971 3.7 2.6 4.6 2.5 1187.0 13.4 --------------------------------------------------- Total: 44.8 34.3 57.8 30.2 13787.0 --> 167.1 Total when ALL b,r values > 2.0: 43.6 33.5 56.1 29.5 11987.0 --> 162.7 (limit=156.5) --------------------------------------------------- 09:11Z Moonrise Cartridge 7, plate 3426 - SEGUE2 Apr 09d ---------------------------------------- 09:38Z - GSOGTF This plate's plug map file has no guide star magnitudes, hence we get no reading on the efficiency meter.
