Subject: 2.5m obslog 20110910 (MJD 55815) From: snedden@apo.nmsu.edu Date: Sun, 11 Sep 2011 12:52:19 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday September 10, 2011 (MJD 55815) ---- Observing Team ---- Kaike Pan Steph Snedden ---- Observing Plan ---- APOGEE 9.7 hours ---- Observing Summary ---- More than half the night was lost to thick clouds and nearby radar return. During second half we were able to observe: Cartridge 4, plate 5221 - APOGEE - N 188 (Color-cut) - Done, we think. Cartridge 7, plate 5282 - APOGEE Pal1_111 - NOT Done. (note: end of night calibrations are not summarized in this log, but were started.) While it was cloudy, we completed dithered flats on cartridge 12. Details below. Tonight, we turned off the scale change loop for part of an exposure and the guider offset jumps that we have been seeing stopped. Therefore, the more frequent jumps we have been seeing since the end of shutdown appear to be related to the mirror adjustments when changing the scale. ---- Observing Log ---- Afternoon: --------- 00:51Z - Started ventilation. Doors opened. Actors checked and OK. No problems noted at the telescope during checkout. Afternoon APOGEE cals started. Night: ----- 01:21Z - Although we had mostly clear skies an hour before sunset, a storm started to blow up nearby and by sunset was a threat. We stayed closed. 03:01Z - Weather was threatening enough that we decided we had time to do BOSS dithered flats Cartridge 12, plate 4381 - Dithered Flats ----------------------------------------- Focus first 03:20:43 hartSp2: r=267, b=0.9, txt=OK, sp2Temp = 12.2 ; 03:20:43 sos.sp2AverageMove = -75 03:20:47 motorPos.sp2.move: -74, -74, -75; 03:20:47 hartSp1: r=224, b=0.8, txt=OK, sp1Temp = 12.5 ; 03:20:47 sos.sp1AverageMove = -531 03:20:50 motorPos.sp1.move: -531, -532, -532; Check WAVEMID, WAVESIGMA, XMID, XSIGMA 03:21:29 boss exposure 0.0, file=133912 03:22:31 boss Idle 03:22:51 boss exposure 30.0, file=133913 03:24:27 boss Idle 03:30:23 boss exposure 4.0, file=133914 03:31:33 boss Idle Start of dithered flats 03:36:49 motorPos.sp1.move: 682, 683, -680; 03:36:53 motorPos.sp2.move: 682, 681, -682; 03:37:12 boss exposure 30.0, file=133915 03:38:45 boss Idle 03:38:48 motorPos.sp1.move: -62, -61, 61; 03:38:52 motorPos.sp2.move: -62, -61, 61; 03:39:11 boss exposure 30.0, file=133916 03:40:44 boss Idle 03:40:47 motorPos.sp1.move: -62, -62, 62; 03:40:51 motorPos.sp2.move: -62, -62, 63; 03:41:10 boss exposure 30.0, file=133917 03:42:42 boss Idle 03:42:46 motorPos.sp1.move: -62, -61, 63; 03:42:49 motorPos.sp2.move: -62, -62, 62; 03:43:08 boss exposure 30.0, file=133918 03:44:41 boss Idle 03:44:45 motorPos.sp1.move: -62, -63, 61; 03:44:49 motorPos.sp2.move: -62, -62, 62; 03:45:08 boss exposure 30.0, file=133919 03:46:41 boss Idle 03:46:45 motorPos.sp1.move: -62, -62, 62; 03:46:48 motorPos.sp2.move: -62, -63, 61; 03:47:09 boss exposure 30.0, file=133920 03:48:42 boss Idle 03:48:45 motorPos.sp1.move: -62, -59, 63; 03:48:49 motorPos.sp2.move: -62, -62, 65; 03:49:08 boss exposure 30.0, file=133921 03:50:40 boss Idle 03:50:44 motorPos.sp1.move: -62, -65, 61; 03:50:48 motorPos.sp2.move: -62, -62, 59; 03:51:07 boss exposure 30.0, file=133922 03:52:40 boss Idle 03:52:44 motorPos.sp1.move: -62, -63, 62; 03:52:47 motorPos.sp2.move: -62, -61, 63; 03:53:06 boss exposure 30.0, file=133923 03:54:39 boss Idle 03:54:42 motorPos.sp1.move: -62, -61, 63; 03:54:46 motorPos.sp2.move: -62, -63, 62; 03:55:06 boss exposure 30.0, file=133924 03:56:38 boss Idle 03:56:42 motorPos.sp1.move: -62, -62, 61; 03:56:46 motorPos.sp2.move: -62, -62, 61; 03:57:06 boss exposure 30.0, file=133925 03:58:39 boss Idle 03:58:42 motorPos.sp1.move: -62, -62, 61; 03:58:46 motorPos.sp2.move: -62, -62, 64; 03:59:05 boss exposure 30.0, file=133926 04:00:38 boss Idle 04:00:41 motorPos.sp1.move: -62, -63, 62; 04:00:45 motorPos.sp2.move: -62, -61, 61; 04:01:04 boss exposure 30.0, file=133927 04:02:37 boss Idle 04:02:44 motorPos.sp1.move: -62, -62, 62; 04:02:47 motorPos.sp2.move: -62, -62, 61; 04:03:06 boss exposure 30.0, file=133928 04:04:39 boss Idle 04:04:43 motorPos.sp1.move: -62, -56, 63; 04:04:50 motorPos.sp2.move: -62, -59, 63; 04:05:09 boss exposure 30.0, file=133929 04:06:41 boss Idle 04:06:45 motorPos.sp1.move: -62, -68, 60; 04:06:48 motorPos.sp2.move: -62, -62, 62; 04:07:09 boss exposure 30.0, file=133930 04:08:41 boss Idle 04:08:45 motorPos.sp1.move: -62, -62, 63; 04:08:49 motorPos.sp2.move: -62, -62, 61; 04:09:08 boss exposure 30.0, file=133931 04:10:40 boss Idle 04:10:44 motorPos.sp1.move: -62, -62, 63; 04:10:47 motorPos.sp2.move: -62, -62, 62; 04:11:08 boss exposure 30.0, file=133932 04:12:41 boss Idle 04:12:44 motorPos.sp1.move: -62, -62, 61; 04:12:48 motorPos.sp2.move: -62, -62, 65; 04:13:07 boss exposure 30.0, file=133933 04:14:39 boss Idle 04:14:46 motorPos.sp1.move: -62, -61, 63; 04:14:50 motorPos.sp2.move: -62, -62, 59; 04:15:09 boss exposure 30.0, file=133934 04:16:42 boss Idle 04:16:46 motorPos.sp1.move: -62, -59, 62; 04:16:49 motorPos.sp2.move: -62, -62, 64; 04:17:08 boss exposure 30.0, file=133935 04:18:41 boss Idle 04:18:44 motorPos.sp1.move: -62, -66, 61; 04:18:48 motorPos.sp2.move: -62, -62, 60; 04:19:07 boss exposure 30.0, file=133936 04:20:40 boss Idle Collimator mirrirs moved back 04:20:44 motorPos.sp1.move: 619, 620, -620; 04:20:48 motorPos.sp2.move: 620, 619, -619; 07:55Z - Clouds started to thin and radar return to retreat. We decide to open for ASDAF with a bright ancillary science target. Cloud cover was pretty thick, but uniform and we could see the Moon but not many other stars. Cartridge 5, plate 5258 ======================= 2MASS J03322626+4603247 H=4.44 RA=53.109416 Dec=46.056862 Target in Fabbian ancillary program Centered in guide fiber 10, then took a couple of exposures in two science fibers to check the ADUs. Exposure time was too low, so no useful data. While we were setting up, the sky cleared out more, so we stopped ASDAF to switch to science. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - N UT File/Exp Imagetype ObjName Nread Dth Comment - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 11 08:35 02530011 Object ObjName 3 A J03322626+4603247 Fiber 204 (check exposure time) 12 09:03 02530012 Object ObjName 3 A J03322626+4603247 Fiber 191 (check exposure time) 09:25Z - Cartridge 4, plate 5221 - APOGEE - N 188 (Color-cut) ============================================================= GSOGTF(!)

There was not enough time left in the night to do two. Clouds staedily got worse through the sequence. The signal was lower than we expected however, so this plate is definitely NOT done. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - N UT File/Exp Imagetype ObjName Nread Dth Comment - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 25 10:43 02530025 Object ObjName 14 A sky flat, offset 0.01 degree in 26 10:46 02530026 Object ObjName 14 B sky flat, offset 0.01 degree in 27 10:48 02530027 Object ObjName 14 B sky flat, offset 0.01 degree in 28 10:51 02530028 Object ObjName 14 A sky flat, offset 0.01 degree in 29 10:52 02530029 DomeFlat ObjName 5 A None 30 10:56 02530030 Dark ObjName 10 A None 31 10:57 02530031 Dark ObjName 10 A None 32 11:26 02530032 Object ObjName 47 A cart 7, plate 5282, Pal1_111 33 11:35 02530033 Object ObjName 47 B cart 7, plate 5282, Pal1_111 34 11:36 02530034 Object ObjName 47 B cart 7, plate 5282, Pal1_111 35 11:52 02530035 Object ObjName 47 A cart 7, plate 5282, Pal1_111 36 11:57 02530036 DomeFlat ObjName 5 A None 37 12:00 02530037 Dark ObjName 10 A None 38 12:02 02530038 Dark ObjName 10 A None 12:16Z - Closed enclosure.
