APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday January 12, 2009 (MJD 54844) ---=== OBSERVING TEAM ===--- Smitry Bizyaev (observer) Alaina Shelden (training) Steph Snedden (swing) Scott Fleming (UF) Jiwei Xue (UF) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clear night with sometimes very bad seeing. Marvels plates exposed: 3084 (c 7) A & B, 3075 (c 4) B 3086 (c 6) B 3088 (c 1) A & B 3089 (c 5) B 3078 (c 9) B Marvels pre-selection plate 3002 (c 2) was observed 5x20 sec, but SoS doe not reduce spectro data now, see "problems" section. Jon or Fritz, please, take a look at this. We don't declare the plate 3002 as done because of this. ---=== OBSERVING LOG ===--- Afternoon: --------- No problems noted during afternoon checkout. Spectrograph focus left set for an air temp of about 3C. Details after the problems section. Removed MJD 54813 data from sdsshost2/sdssfiles1. Cartridge 7 mounted. Night: ----- 00:31Z enclosure opened. MS calibration 01:24Z gotoField with cart. 7 plate 3084 f. B fk5 used scale change, focusing. 01:45Z MS exposure 50 min Seeing is really awful during this exposure. Started with 2.2", rose to 3.5". Guider lost stars sometimes because of the poor seeing. MS calibration gotoField with field B. GSOGTF Seeing is 3.6-4" with good focusing. Start of the MS exposure is postponed. 03:20Z seeing is gtting better, temperature changed from -4.3C to -1.3C. Seeeing is now ~ 2.5". Started 50 min MS exposure. MS calibration 04:15Z cart. 4 plate 3075 f. B is plugged on 04:35Z MS exposure started, 50 min Seeing is getting better and better, improved from ~4" to 1.4". 05:30Z cart. 6 plate 3086 f. B is mounted fk5 did not help. Spiral pattern used. 05:59Z MS exposure 50 min === 06:05Z scale change test started I changed the plate scale, Scott took mean flux from Marvels's PMT averaged over 2 minutes. It loks like changing seeing affects results very much, it is hard to separate effects from changing scale alone. Scott has all results. === 07:00Z cart 1 plate 3088 f.

Since the problem was found at ~ 12:15, ~ 20 min before the twilight, we postpone it for the daytime. cart 7 is mounted 12:58Z enclosure on, ventilation stopped. 13:04Z endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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 58002, plate 3002 ------- 23:14 58002 10.0 flat 23:16 58003 2.0 arc 23:25 58004 3.0 arc 23:28 58005 3.0 arc ----- sequence 58006, plate -9999 ------- 01:20 58006 0.0 bias ----- sequence 58007, plate 3002 ------- 12:10 58007 10.0 flat 12:13 58008 2.0 arc 12:18 58009 21.0 target 12:22 58010 21.0 target 12:27 58011 20.0 target 12:30 58012 21.0 target 12:35 58013 20.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:55Z 7 3084 -113.22 -0.0034 48.60 -0.0023 98.03 0.0025 0.999920 03:31Z 7 3084 -104.47 -0.0026 44.57 -0.0036 106.30 0.0024 0.999860 04:50Z 4 3075 284.64 -0.0031 59.63 -0.0017 119.37 0.0155 0.999790 06:05Z 6 3086 176.31 -0.0017 62.72 -0.0071 -6.09 0.0099 0.999820 08:42Z 1 3088 243.83 -0.0071 61.24 -0.0019 85.18 0.0074 0.999920 10:13Z 5 3089 228.21 -0.0038 53.80 -0.0041 78.17 0.0066 0.999880 11:02Z 9 3078 212.26 -0.0034 48.16 -0.0047 69.58 0.0192 0.999930 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:55Z 7 3084 0.99992 789 2159 320 -113 48.6 -3.4 17 67 -- 2.6" 03:31Z 7 3084 0.99986 1381 2493 150 -104 44.6 -1.2 1 74 -- 2.7" 04:50Z 4 3075 0.99979 2073 3019 150 285 59.6 -1.7 16 353 -- 1.6" 06:05Z 6 3086 0.99982 1776 2787 170 176 62.7 -2.8 6 356 -- 1.7" 08:42Z 1 3088 0.99992 789 2003 200 244 61.2 -3.8 13 353 -- 2.2" 10:14Z 5 3089 0.99988 1184 2350 200 228 53.8 -3.5 5 343 -- 1.5" 11:02Z 9 3078 0.99993 691 1919 160 212 48.1 -4.6 9 350 -- 1.4" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:14Z 32 11 16 22 (NNE) 232 - 23:47Z 32 12 0 213 (SSW) 247 - 00:19Z 31 11 0 270 (W) 256 - clear 01:21Z 28 11 12 63 (ENE) 363 - '' 01:52Z 26 11 14 74 (ENE) 856 - '' 02:23Z 25 12 18 54 (NE) 1092 - '' 02:53Z 25 13 15 52 (NE) 1142 - '' 03:25Z 29 10 19 0 (N) 402 - '' 03:55Z 30 11 18 1 (N) 357 - '' 04:25Z 29 11 18 343 (NNW) 409 - '' 04:57Z 28 11 5 8 (N) 305 - '' 05:29Z 28 11 11 340 (NNW) 303 - '' 05:59Z 27 12 9 308 (NW) 400 - '' 06:31Z 26 11 6 344 (NNW) 430 - '' 07:01Z 25 12 3 267 (W) 454 - '' 07:31Z 24 12 2 328 (NNW) 455 - '' 08:03Z 25 11 4 344 (NNW) 491 - '' 08:34Z 25 10 10 8 (N) 339 - '' 09:04Z 25 9 6 330 (NNW) 200 - '' 09:34Z 26 8 11 334 (NNW) 170 - '' 10:04Z 25 9 7 356 (NNW) 201 - '' 10:35Z 25 10 9 318 (NW) 201 - '' 11:08Z 23 10 5 357 (NNW) 231 - '' 11:40Z 23 11 9 337 (NNW) 267 - '' 12:14Z 22 11 5 301 (WNW) 353 - '' 12:44Z 20 13 9 323 (NW) 601 - '' ---=== TELESCOPE STATUS ===--- 23:45Z - Started building ventilation 23:45Z - Began ventilation.

Since the spectro temps run warmer than air temps, we are in spec for an air temp of about 3C. I decided to leave the focus unchanged, given the temperature uncertainty range for tonight. If it gets colder than expected, we could end up in the yellow.

We did sos_stop / sos_start , didnt help. Probably something got "umounted" during the night. Jon or Fritz, could you please take a look at this? Because of this problem we cannot decide if spectrographs were in focus during the Marvels pre-selecion exposures.
