APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday August 19, 2004 (MJD 53237) ---=== OBSERVING TEAM ===--- swing: Jurek Krzesinski night: Pete Newman, Howard Brewington. Support: Wendel, Carlos, Steven, and Connie (phone) Visitors: Mickey Coleman and Dominic Corlucci Jeff Hayes ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Plates 1886 and 1890 were declared done. And, we got more signal on plate 1144. ---=== OBSERVING LOG ===--- Afternoon: ----------- Work done on spectrographs this afternoon. We had to powercycle spectrograph 1, then got problem with spectrograph ptvme, which went away after we rebooted spectrogrph crate. Then we were able to talk to spectrgraphs and iack them. Shortly after that sos complained about bad ngood fiber in r2, which lead us back to crosstalk problem. Connie was called. We decided to swapp DB15 r2/b2 wires to see if we can see crosstalk in b2 frame, but we didn't. We swapped wires back and saw again crosstalk on r2, but on much less scale than before. At this point we decided to swap DB15 r2 wire with a spare one. Next arc exposre with the new cable didn't show crosstalk. We took more exposures with this setup trying to find crosstalk - we didn't see any. History: frames: 28110 - 28126 - found crosstalk 28127, 28128 - (arc, bias) r2/b2 DB15 wires swapped - no crosstalk 28129, 28130 - (arc, bias) r2/b2 DB15 wires back on their own places - crosstalk visible again. new 15 pin wire was put to replace the old r2 DB15 one. 28131 - up - (arc) -no cross talk. Connie says that histogram now looks very different than before! It is a good sign she says. Spectrograph collimation was checked after that and it needed recollimation on sp1 (see problem section). MIGs -ok. Da, imager - ok. Telescope ok. Night: ------- 01:43Z We had clouds at Sunset. 05:30Z Clouds are clearing. 05:50Z Doors and louvers opened, fans on. 06:15Z Enclosure off. 06:36Z Cart 02, plate 1890 (segue98). Guide stars on goToField with last night's offsets. Plate was finished with three exposures. 07:50Z Cart 09, plate 1144 (rockosi50). Guide stars on goToField. This plate was of lower priority, but we tried to finish it because of existing signal and expiration date. During the second exposure at 08:32Z, Jeff Hayes drove on to the site with his headlights on. The scope was facing southwest, however, and we do not think the lights caused a problem. Although four exposures were completed, we were unable to declare this plate done; see below. MJD b1 r1 b2 r2 53227 5.4 2.6 6.4 5.2 53237 28.0 8.0 39.4 30.0 ------------------------- Total 33.4 10.6 45.8 35.2 Plate 1144 asked for a postCal; unfortunately, it did not get one. 10:01Z Cart 07, plate 1886 (segue98). Guide stars on goToField, yet we had to disable guide fibers 5 and 11 because they were guiding on hot pixels. We recommend that a new set of dark frames be completed during the afternoon checkout (20 Aug). This plate was declared done in three exposures. endNight finished and was happy. See problems section for misc watcher messages. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4781 22:39Z 22:55Z 100 O 17.50 21.72 42 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 28113, plate -9999 ------- 22:42 28113 0.0 bias 22:47 28115 0.0 bias 22:56 28116 0.0 bias 22:59 28117 0.0 bias ----- sequence 28118, plate 1144 ------- 23:03 28118 0.0 bias 23:12 28119 0.0 bias 23:15 28120 10.0 flat 23:19 28121 2.0 arc 23:27 28122 0.0 bias 23:30 28123 10.0 flat 23:32 28124 2.0 arc 23:36 28125 2.1 arc 23:38 28126 2.1 arc 00:24 28127 2.0 arc 00:33 28128 0.0 bias 00:48 28129 2.0 arc 00:51 28130 0.0 bias 01:03 28131 2.0 arc 01:06 28132 0.0 bias 01:14 28133 2.0 arc 01:18 28134 2.0 arc 01:24 28135 2.0 arc 01:27 28136 0.0 bias 01:30 28137 10.0 flat 01:32 28138 2.0 arc 01:35 28139 2.1 arc 01:38 28140 2.1 arc 01:56 28141 2.1 arc 01:58 28142 2.1 arc ----- sequence 28143, plate -9999 ------- 02:11 28143 0.0 bias ----- sequence 28144, plate -9999 ------- 05:38 28144 0.0 bias ----- sequence 28145, plate 1890 ------- 06:54 28145 10.0 flat 06:56 28146 2.0 arc 07:16 28147 900.1 target 07:28 28148 600.1 target 07:41 28149 600.1 target ----- sequence 28150, plate 1144 ------- 07:58 28150 10.0 flat 08:00 28151 2.0 arc 08:21 28152 900.1 target 08:44 28153 1200.1 target 09:19 28154 1800.1 target 09:52 28155 1800.1 target ----- sequence 28156, plate 1886 ------- 10:05 28156 10.0 flat 10:08 28157 2.0 arc 10:36 28158 900.1 target 10:54 28159 900.1 target 11:12 28160 900.1 target 11:15 28161 10.0 flat 11:17 28162 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 06:59Z 2 1890 -22.57 0.0004 66.24 0.0003 160.75 0.0189 1.000280 08:05Z 9 1144 -16.02 0.0036 56.16 -0.0010 166.49 0.0060 1.000240 09:31Z 9 1144 -47.34 0.0036 46.47 -0.0010 141.71 0.0060 1.000270 10:23Z 7 1886 227.31 0.0074 67.09 -0.0012 62.92 -0.0309 1.000250 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL7709 Stays: JL7710 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 06:59Z 2 1890 1.00028 -2764 -1121 30 -22 66.3 12.0 0 266 gdr 1.2 08:04Z 9 1144 1.00024 -2369 -819 -20 -16 56.2 10.7 4 245 gdr 1.2 10:23Z 7 1886 1.00025 -2468 -927 -20 227 67.1 11.4 5 316 gdr 1.0 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:01Z 60 39 17 226 (SW) 119261 - clouds 22:34Z 61 40 18 237 (WSW) 119032 - 23:05Z 60 42 13 265 (W) 122259 - 23:38Z 59 40 11 256 (WSW) 120010 - 00:09Z 64 41 14 263 (W) 120804 - 00:42Z 59 39 12 266 (W) 121226 - clouds 01:12Z 58 39 11 268 (W) 122878 - 01:43Z 58 41 12 246 (WSW) 123440 - 02:36Z 56 41 6 307 (NW) 125129 - 03:08Z 55 40 6 319 (NW) 123854 - 03:40Z 55 39 12 304 (NW) 124036 - clouds 04:12Z 55 39 13 307 (NW) 123594 - 04:45Z 54 39 11 288 (WNW) 123015 - clearing 05:17Z 53 40 10 315 (NW) 123677 - 05:47Z 53 41 4 348 (NNW) 124879 - 06:17Z 52 41 10 326 (NW) 126691 - 06:47Z 53 40 2 280 (W) 125585 - clear 07:18Z 53 40 4 354 (NNW) 125731 - 07:49Z 53 40 8 320 (NW) 124408 - 08:21Z 51 41 1 262 (W) 126277 - 08:54Z 52 40 1 326 (NW) 125755 - clear 09:27Z 52 40 0 269 (W) 125749 - 09:58Z 52 40 1 262 (W) 125863 - 10:28Z 52 40 6 319 (NW) 126133 - 10:58Z 51 40 4 344 (NNW) 125172 - clear 11:29Z 51 40 6 344 (NNW) 125070 - ---=== TELESCOPE STATUS ===--- 05:50Z Doors and louvers opened, fans on. 06:15Z Enclosure off 11:35Z Enclosuere on, doors and louvers closed, fans off.
