APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday January 8, 2009 (MJD 54840) ---=== OBSERVING TEAM ===--- Audrey Simmons Steph Snedden (afternoon) Jiwei Xue (MARVELS) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Partly cloudy for the first half, then the clouds cleared. Obtained exposures on the following MARVELS plates in mostly good, but variable seeing: Cart 4, plate 3075A&B Cart 7, plate 3084A&B Cart 3, plate 3077A&B Cart 6, plate 3086B Cart 1, plate 3087B Cart 5, plate 3089B Cart 9, plate 3078B The flap, below the telescope, on the door of the confined space is difficult to open and close. ---=== OBSERVING LOG ===--- Afternoon: ---------- Watcher errors for sp1 micro. Issued an iack and everything worked again.

Spectro focus left at ~4C. 23:49Z - Mounted cart 4, MARVELS plate 3075. Opened doors. Night: ------ 00:15Z - Opened enclosure to partly cloudy skies. 00:18Z - Sunset. 00:42Z - goToField cart 4, MARVELS plate 3075A. Used fk5 to find field since it is still bright outside. Lots of clouds; efficiency low. 01:10Z - 50 min MARVELS exposure. Seeing 1.0" 02:01Z - Mounted cart 7, MARVELS plate 3084A. GSFOGTF. Some clouds. 02:17Z - 50 min exposure. Seeing 1.4" 03:13Z - Switched to field B of MARVELS plate 3084B. GSFOGTF. Some clouds. 03:24Z - 50 min exposure. Seeing 1.4" 04:16Z - Mounted cart 4, MARVELS plate 3075B. GSFOGTF. Rather large scale change needed. Some clouds. 04:33Z - 50 min exposure. Seeing 1.2" 05:32Z - Mounted cart 3, MARVELS plate 3077A. No GSFOGTF. Cleared the offsets and found the field with the glow off of the fk5 in fiber 9. Pretty large scale change needed. Mostly clear. 05:49Z - 50 min exposure. Seeing 1.5" 06:51Z - Switched over to side B of plate 3077B. GSFOGTF plus a small offset. Some clouds. Only able to guide on three stars found in fibers 4,6, and 8. No stars in fibers 2 and 11. 06:59Z - 50 min exposure. Seeing 1.2" 07:50Z - Mounted cart 6, MARVELS plate 3086B. Had to change cartridge numbers in the plugmapM file. Used fk5. Large scale change (>0.03). Clouds cleared. 08:15Z - 50 min exposure. Seeing 1.1" 09:08Z - Mounted cart 1, MARVELS plate 3087B. Again had to change the plugmapM file. Found the field with an fk5 by clearing the offsets. Again, large scale change. 09:30Z - 50 min exposure. Seeing 1.2" 10:21Z - Mounted cart 5, MARVELS plate 3089B. Changed plugmapM file. Used fk5. Large scale change. 10:41Z - 50 min exposure. Seeing 1.2" 11:33Z - Mounted cart 9, MARVELS 3078B. GSFOGTF. 11:49Z - 50 min exposure. Seeing 1.4" 12:52Z - Closed enclosure. Stopped ventilating. 12:54Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7897 22:55Z 23:26Z 100 O 161.44 169.29 65 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 57974, plate -9999 ------- 23:00 57974 0.0 bias 23:04 57975 0.0 bias 23:15 57976 0.0 bias ----- sequence 57977, plate -9999 ------- 23:24 57977 0.0 bias 23:29 57979 0.0 bias ----- sequence 57980, plate 3178 ------- 23:34 57980 10.0 flat 23:37 57981 2.0 arc 23:41 57982 3.0 arc 23:44 57983 3.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 00:57Z 4 3075 -24.48 -0.0014 76.61 0.0010 158.16 0.0321 1.000090 02:17Z 7 3084 246.50 -0.0022 47.35 -0.0000 98.83 -0.0005 1.000060 03:18Z 7 3084 257.86 -0.0025 50.32 -0.0012 104.30 -0.0018 1.000000 04:33Z 4 3075 293.33 -0.0019 66.05 0.0007 124.21 0.0217 0.999880 05:49Z 3 3077 205.01 -0.0010 38.74 -0.0007 81.46 0.0325 1.000130 06:59Z 3 3077 229.86 -0.0023 39.28 0.0007 96.83 0.0138 1.000090 08:15Z 6 3086 203.77 -0.0023 58.15 -0.0040 42.78 0.0046 0.999920 09:30Z 1 3087 -56.23 -0.0005 48.01 0.0023 135.46 0.0078 1.000070 10:41Z 5 3089 228.80 -0.0021 51.88 -0.0014 80.98 0.0022 0.999980 11:49Z 9 3078 213.82 -0.0017 44.51 -0.0015 77.68 0.0173 1.000070 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 22:56Z 8 0 1.00011 -1085 310 -75 121 30.2 6.5 2 281 - N/A 00:57Z 4 3075 1.00009 -888 636 250 -24 76.6 5.4 9 357 - 1.0 02:17Z 7 3084 1.00006 -591 899 200 246 47.3 4.5 15 331 - 1.4 03:18Z 7 3084 1.00000 1 1254 75 258 50.3 5.3 13 346 - 1.4 04:33Z 4 3075 0.99988 1184 2169 50 293 66.1 5.6 10 330 - 1.2 05:49Z 3 3077 1.00013 -1283 208 50 205 38.8 5.3 9 269 - 1.5 06:59Z 3 3077 1.00009 -888 483 0 230 39.3 5.7 14 292 - 1.2 08:15Z 6 3086 0.99992 789 1911 100 204 58.2 4.7 10 265 - 1.1 09:30Z 1 3087 1.00007 -690 590 -25 -56 48.0 5.9 8 280 - 1.2 10:41Z 5 3089 0.99998 199 1388 50 229 51.9 5.1 20 293 - 1.2 11:49Z 9 3078 1.00007 -690 652 25 214 44.5 5.4 19 281 - 1.4 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:10Z 45 11 10 336 (NNW) 56 - Partly cloudy 22:42Z 44 12 6 6 (N) 80 - " 23:16Z 42 12 13 350 (NNW) 93 - " 23:48Z 43 12 11 354 (NNW) 64 - " 00:20Z 42 11 21 344 (NNW) 92 - " 00:53Z 42 13 9 7 (N) 68 - " 01:23Z 41 15 13 332 (NNW) 98 - " 01:56Z 40 16 13 349 (NNW) 106 - " 02:28Z 40 16 6 349 (NNW) 98 - " 03:01Z 41 15 10 330 (NNW) 100 - " 03:33Z 42 15 15 317 (NW) 99 - " 04:05Z 42 15 15 321 (NW) 107 - " 04:37Z 41 16 14 322 (NW) 94 - " 05:10Z 42 15 12 303 (WNW) 96 - " 05:40Z 42 16 14 298 (WNW) 112 - " 06:13Z 42 14 14 296 (WNW) 128 - " 06:44Z 43 15 15 289 (WNW) 100 - " 07:14Z 41 13 10 280 (W) 202 - " 07:46Z 40 13 7 278 (W) 167 - " 08:18Z 40 13 9 266 (W) 164 - Clear 08:51Z 41 13 17 280 (W) 116 - " 09:23Z 42 10 21 274 (W) 117 - " 09:53Z 42 10 21 271 (W) 96 - " 10:25Z 41 10 13 273 (W) 88 - " 10:59Z 41 10 15 285 (WNW) 84 - " 11:31Z 40 9 12 249 (WSW) 100 - " 12:01Z 40 7 17 266 (W) 106 - " 12:32Z 40 6 14 269 (W) 90 - " ---=== TELESCOPE STATUS ===--- 23:20Z - Began ventilation.
