APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday October 30, 2008 (MJD 54770) ---=== OBSERVING TEAM ===--- Elena Malanushenko (swing) Viktor Malanushenko Stephanie Snedden ---=== OBSERVING PLAN ===--- Science! 30 Oct 2008 54770.0 0.14 BOSS/SEGUE 10.3 hours ---=== OBSERVING SUMMARY ===--- Not quite photometric during first half, with average to excellent seeing. Photometric during second half with good to excellent seeing. SEGUE plate 3135 declared done Accumulated more signal on SEGUE plates 3114, 3128, 3143, but they are not yet done. Imaged part of strip 83 S (see log body for details) Imaged part of strip 68 S (see log body for details) ---=== OBSERVING LOG ===--- Afternoon: ========== All systems are checked and they work properly. Spectro collimation is adjusted for 9C. 23:40 ventilation Cart 4 is mounted. Night: ====== There were a few clouds around, so we started with spectroscopy. 00:38Z - Slewed to field in bright twilight. 00:44Z - Cartridge 4, plate 3128, SEGUE --------------------------------------- Found an FK5 in bright twilight. Added two exposures totaling 3300 sec to pre-existing signal. Added (S/N)^2 = 5.6 in r2, so the plate is now at: b1 r1 b2 r2 42.9 39.7 31.3 26.6 Not yet done. The skies were borderline photometric, but there was some structure (in addition to the electronic noise, Howard, which was still present), that took us out of photometric conditions from time to time. We stayed with spectroscopy. 02:32Z - Cartridge 8, plate 3143 SEGUE -------------------------------------- GSOGTF Took four exposures totaling 7200s. Total (S/N)^2 after adding in signal from a previous night is b1 r1 b2 r2 39.1 40.2 42.8 31.3 Not quite done. 03:54Z - photometric, but clouds were nearby, and we did not trust it to stay clear. We continued with spectroscopy. 05:00Z - Still not quite photometric. Dust counts started to rise, so we speculate that the structure we were seeing was dust. 05:15Z - Cartridge 6, plate 3135, SEGUE --------------------------------------- GSOGTF We took two exposures totaling 1548 sec. Adding this to previous signal we get b1 r1 b2 r2 97.8 53.9 114.8 50.5 This plate is DONE 06:05Z - Cartridge 7, plate 3114, SEGUE --------------------------------------- GSOGTF One 1200 sec. exposure was made. The (S/N)^2 values are: b1 r1 b2 r2 6.0 3.1 9.8 6.9 There is no prior signal on this plate. It is not yet done. 06:53Z - Finally the sky camera sigma dropped to photometric values. Mounted the imager. 07:01Z - Run 7780, 83 S, startLambda -170 ----------------------------------------- Skippy happy from the beginning. Focus loop good by frame 23 07:12Z start of ramp, frame 25, lambda -167 07:20Z start of science, frame 39, lambda -165 09:00Z end of science, frame 205, lambda -140 09:08Z end of ramp, frame 218, lambda -138 09:13Z - Run 7781, 68 S, startLambda -177 ----------------------------------------- Skippy good from frame 10 Focus loop good from frame 12 09:20Z - start of ramp, frame 18, lambda -175 09:28Z - start of science, frame 32, lambda -173 10:40Z - end of science, frame 152, lambda -155 10:48Z - end of ramp, frame 165, lambda -153 There was less than an hour to twilight, including the time needed for a bias, so we chose to let the drift continue past the end of the survey footprint. The seeing started to get worse (about 1.5 asec FWHM, then back down to 1.2) at lambda -144, frame 228. 11:39Z - ended the drift at frame 252, lambda -140. 11:42Z - Run 7782, bias.
