APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday January 6, 2009 (MJD 54838) ---=== OBSERVING TEAM ===--- Steph Snedden Audrey Simmons Kaike Pan (swing) French Leger (support) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The night was mostly lost due to high wind gusts and blowing snow. We obtained one exposure on cart 4, MARVELS plate 3075A. The power supply on the red spectrograph 2 camera failed at 08:15Z (display read -5V). French swapped out the supply with a spare. More details, see log. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems were checked and working properly. Spectro Focus was checked but no adjustment made. It still set for about - 3C. 23:35Z mounted cart 4, started ventilation. Night: ------ Delayed opening due to blowing snow. 00:09Z - Sunset. 01:16Z - Opened enclosure to partly cloudy skies. ** 01:34Z - goToField cart 4, MARVELS plate 3075A. Azimuth aborted during slew. GSFOGTF with a slight offset. 01:38Z - 18-degree evening twilight. 01:46Z - Started 50 min exposure. Seeing 2.0" 02:09Z - Volts watcher error, vs+ for CCD 55. ** 02:39Z - Mounted cart 7, MARVELS plate 3084B. During the cartridge change, we noticed there were pretty strong wind gusts (33mph) and lots of snow in the air. We closed but kept ventilating. 07:16Z - Wind kept getting worse. 41 mph gusts. 08:00Z - High dust counts. 08:12Z - Secondary Dewar Pressure Fault, ln2temp, and all of the voltage watcher errors for spectrograph 2 complained. 'cc tcheck' showed camera 2 not reading the correct ccdtemp information (0C) and camera 3 read a value lower than normal (-68C). Forced a primary and a secondary fill as a precaution. At the telescope, there was a red LED lit on the the power supply for the red camera on spectrograph 2. The display read -5V. French swapped out the supply with a spare. 10:25Z - 49 mph gusts. 10:36Z - 55 mph gusts. 11:55Z - The wind was not letting up. We called it a night. Ventilation stopped. 12:01Z - endNight rejoiced. 12:44Z - 18-degree morning twilight. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7893 23:02Z 23:19Z 100 O 161.41 165.70 41 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 57955, plate -9999 ------- 23:05 57955 0.0 bias ----- sequence 57956, plate 3178 ------- 23:11 57956 10.0 flat 23:14 57957 2.0 arc 23:17 57958 3.0 arc 23:20 57959 2.0 arc ----- sequence 57960, plate -9999 ------- 00:00 57960 0.0 bias 00:07 57961 0.0 bias ----- sequence 57962, plate -9999 ------- 09:37 57962 0.0 bias 09:41 57963 0.0 bias ----- sequence 57964, plate 3084 ------- 09:44 57964 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:46Z 4 3075 -53.90 -0.0019 70.90 -0.0018 133.52 0.0211 0.999950 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:47Z 4 3075 0.99995 494 2038 500 -54 70.9 -6.7 12 352 - 2.0 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:12Z 20 14 5 38 (NE) 234 - Clear 22:44Z 20 14 13 321 (NW) 291 - " 23:15Z 20 13 1 266 (W) 278 - " 23:46Z 20 11 11 321 (NW) 322 - " 00:26Z 20 10 13 329 (NNW) 311 - " 00:58Z 19 10 2 313 (NW) 343 - Partly cloudy 01:28Z 19 10 12 332 (NNW) 252 - " 01:58Z 19 9 6 333 (NNW) 303 - Windy! 02:30Z 19 9 7 354 (NNW) 795 - " 03:03Z 20 9 11 10 (N) 350 - " 03:35Z 20 8 22 353 (NNW) 187 - " 04:07Z 20 9 14 22 (NNE) 229 - " 04:39Z 19 10 11 17 (NNE) 248 - " 05:11Z 19 9 16 18 (NNE) 155 - " 05:43Z 19 9 17 3 (N) 185 - " 06:15Z 18 9 5 19 (NNE) 165 - " 06:48Z 19 8 6 83 (E) 446 - " 07:20Z 19 9 13 22 (NNE) 1182 - " 07:52Z 19 9 23 349 (NNW) 400 - " 08:24Z 19 10 27 7 (N) 430 - " 08:56Z 20 10 19 359 (NNW) 2037 - " 09:28Z 22 9 23 11 (N) 857 - " 09:58Z 23 10 21 17 (NNE) 1301 - " 10:29Z 24 10 19 28 (NNE) 1660 - " 10:59Z 25 9 31 14 (NNE) 3046 - " 11:29Z 25 10 27 12 (NNE) 2211 - " 11:59Z 26 11 37 17 (NNE) 549 - " ---=== TELESCOPE STATUS ===--- 23:35Z - Began ventilation.
