Subject: 2.5m obslog 20071020 (MJD 54394) Date: Sun, 21 Oct 2007 06:21:39 -0600 (MDT) From: elenam@apo.nmsu.edu (Elena M) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday October 20, 2007 (MJD 54394) ---=== OBSERVING TEAM ===--- Steph Snedden Elena Malanushenko ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Segue: We obtained a good signal on seque bright plate 2798 but need more observations to complete the plate. SuperNova: imaged 82S lambda 115 to -125, Clear the most of night, seeing was 1.5-2.5 up to 3". Around 5:00Z the imager was pointed to 17 degrees from the Moon only and we saw scattered Moon light on monitors. ---=== OBSERVING LOG ===--- Afternoon: --------- Spectrograph focus was set for 12C. The telescope systems are checked, they are operated properly. Night: ----- 01:08Z - Cartridge 2, plate 2798 - SEGUE GSOGTF, the sky is clear, seeing is around 1.2". 01:25Z - Precal 01:32Z, 01:54Z, 2:17Z Science exposures, 1200 sec We obtained total s/n 12.9 and need more observations to finish this plate. 03:00Z - We switched to SN imaging 03:07Z - 82 S startLambda 111 Run 7084 Focus and skippy are good from the beginning. 03:07Z Slue and drift from lambda 111. Ramp from lambda 113, frame 19, 03:22Z Science form lambda 115, frame 32 Seeing is 1.3-1.6" at the beginning. Start focus is -510, Sky is clear. 04:05Z Seeing is getting worse, at about 2.5-3.0". Around 5:00Z the imager was pointed to only 17 degrees from the Moon and we saw scattered Moonlight on monitors. Photometric the most of night with some clouds during 5:45Z-6:30Z, 9:00Z-10:00Z, 10:30-11:00. The data may not be good in frames 185-223, 312-331, 739-847 because of bad seeing and clouds. The focusLoop could not work properly at the end of night also. 11:20Z - end of science at frame 833, lambda -125 11:28Z - end of drift at frame 847, lambda -123 11:30Z - On-telescope bias, run 7085 12:00Z - We closed. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame
