APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday December 18, 2008 (MJD 54819) ---=== OBSERVING TEAM ===--- Steph Snedden Viktor Malanuskenko Kaike Pan (swing) ---=== OBSERVING PLAN ===--- Science, 54819.0, 0.51, BOSS/SEGUE until 06:53 (5.4 h), then SEGUE (5.7 h) ---=== OBSERVING SUMMARY ===--- A cloudy, humid, windy at the sunset. After midnight clouds come to us again. Air temperature strongly varyed all night long. It means that we had bad seeing also. We observed and have received a useful S/N for two SEGUE2 plates, 3187 and 3174. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems were checked. No problem to report. Spectro focus was set for about 1 C. High humidity and high dust delayed ventilation. Night: ------ 01:02Z - opened doors, louvers, start ventilations. the difference between T_mirrows and T_air more than 5 degree so we will wait. 01:48Z - enclosure off. --------------------------------------------------- Cart. 8 plate 3187, Nov08c_SEGUE2 , used FK5 02:12:36Z gotoField 02:21:07Z preCalibs 02:29:14Z doNextScience 1500 02:57:04Z doNextScience 1800 03:31:14Z doNextScience 1800 04:04:13Z postCalibs 04:11:54Z doNextScience 1800 04:46:21Z doNextScience 1800 05:19:08Z postCalibs 05:26:31Z doNextScience 1500 05:54:22Z doNextScience 1500 06:22:11Z postCalibs 06:29:16Z doNextScience 1500 MJD b1 r1 b2 r2 Texp Sum --------------------------------------------------- 54819 2.0 1.3 2.4 2.2 1500.0 7.9 54819 3.6 2.2 5.2 3.1 1803.0 14.1 54819 4.8 2.0 5.8 3.3 1801.0 15.9 54819 3.0 2.5 4.1 3.9 1802.0 13.5 54819 4.6 1.8 7.7 3.6 1800.0 17.7 54819 5.3 3.0 6.5 4.3 1501.0 19.1 54819 4.6 2.8 6.1 4.4 1500.0 17.9 54819 3.8 2.4 4.8 3.1 1500.0 14.1 Total: 31.7 18.0 42.6 27.9 13207.0 --> 120.2 Total when ALL b,r values > 2.0: 25.1 14.9 32.5 22.1 9907.0 --> 94.6 --------------------------------------------------- Cart. 3 plate 3174, Nov08c_SEGUE2, GSonGTF 07:04:33Z gotoField 07:16:24Z preCalibs 07:23:43Z doNextScience 1500 07:51:32Z doNextScience 1500 08:19:20Z postCalibs 08:26:08Z doNextScience 1500 08:53:55Z doNextScience 1500 09:22:14Z postCalibs 09:28:56Z doNextScience 1800 10:01:53Z doNextScience 1800 -- thick clouds come to us... 10:35:14Z postCalibs 10:49:35Z doNextScience 1800 -- thick clouds... 11:22:36Z doNextScience 1800 -- bad seeing... 11:56:28Z postCalibs 12:03:04Z doNextScience 1800 -- bad seeing...
