APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday May 18, 2006 (MJD 53874) ---=== OBSERVING TEAM ===--- Steph Snedden Olena Malanushenko Shannon Watters Mike Harvanek (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We have had the first part of night with cloudy and opened around midnight when clouds did not see so terrible. But soon after that the weather is improved and we finished 2 plates (2173, 2152) and obtained good signal on one more plate (2200). The telescope behaved itself, we enjoyed it. ---=== OBSERVING LOG ===--- Afternoon: ---------- The az aborted at 95 degrees when moving from 121 to 90 for the az fiducial check. An axis init cleared the abort and movement proceeded normally after this. The alt fiducial at 75 degrees did not read when going down. The temperature difference between outside and inside the enclosure was quite large (16 C outside, 10.5 C inside) so a full blown collimation check was not performed. The xsigma and wsigma values of the flat and arc show the spectrographs to be in collimation for the inside temperature of 10.5 C. Night: ------ We delayed with opening of telescope because of nearby dense clouds on radar return. 05:10Z. After the weather has been improved and clouds were less strong we have opened the telescope. Cartridge 7, plate 2173, chunk. Used Fk5 stars to find the starts. 5:34 Pre-Calibration Focus is -130, efficiency 50%, T=14C, wind 12 mph, dust 1600. Do-Next-Science 5:41 (expos 1500), 6:09 (1500 - bad), 6:53(1500), 7:23(1500), 7:53 (1500). PostCalibration was required and has been done. The plate is DONE with s/n=14.8 Cartridge 5, plate 2152, chunk This plate has previous signal 4.5. FSonGTF Focus is -130. T=13.2, dust 1.6K, wind 11mph. 8:36 PreCalibration DoNextScience 8:43 (1200), 9:06 (1500) The plate is DONE. Cartridge 8, plate 2200, chunk FSonGTF Focus is -80, efficiency 75%, T=12.8C, wind 11 mph, dust 1400. 9:43 Pre-Calibration DoNextScience 9:51 (1200),10:14 (1200) We could do only 3 exposures before twilight and obtained s/n=7.1. The plate needs to have more observations. 10:45Z Telescope is closed. EndNight is completed. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6153 00:56Z 01:25Z 100 O -40.17 -33.01 62 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): yes QA Procedures Done (y/n): yes UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 39259, plate -9999 ------- 00:53 39259 0.0 bias ----- sequence 39260, plate 2173 ------- 01:02 39260 10.0 flat 01:05 39261 2.0 arc ----- sequence 39262, plate -9999 ------- 01:36 39262 0.0 bias ----- sequence 39263, plate -9999 ------- 02:07 39263 0.0 bias 04:17 39264 0.0 bias ----- sequence 39265, plate 2173 ------- 05:36 39265 10.0 flat 05:38 39266 2.0 arc 06:08 39267 1500.1 target 06:40 39268 1500.1 target 07:22 39269 1500.1 target 07:52 39270 1500.1 target 08:20 39271 1500.1 target 08:23 39272 10.0 flat 08:26 39273 2.0 arc ----- sequence 39274, plate 2152 ------- 08:38 39274 10.0 flat 08:40 39275 2.0 arc 09:05 39276 1200.1 target 09:33 39277 1500.1 target ----- sequence 39278, plate 2200 ------- 09:45 39278 10.0 flat 09:47 39279 2.0 arc 10:13 39280 1200.1 target 10:36 39281 1200.1 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 05:55Z 7 2173 62.53 -0.0013 68.44 0.0026 232.98 -0.0264 1.000050 08:45Z 5 2152 275.46 -0.0024 57.43 0.0020 113.05 -0.0267 1.000050 09:54Z 8 2200 285.14 -0.0024 52.80 0.0023 121.60 -0.0238 1.000140 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:53Z 7 0 1.00000 0 1257 0 121 30.3 15.0 7 244 05:55Z 7 2173 1.00005 -494 595 -130 62 68.5 14.0 7 252 -- 1.3 08:45Z 5 2152 1.00005 -494 620 -130 275 57.5 12.9 7 281 -- 1.0 09:52Z 8 2200 1.00014 -1383 -54 -80 286 53.3 12.9 6 353 -- 1.4 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:25Z 55 30 12 53 (NE) 1131 - clouds 00:57Z 61 27 2 255 (WSW) 3347 - 01:29Z 61 27 0 227 (SW) 3977 - 01:57Z 58 26 8 243 (WSW) 3142 - 02:29Z 57 26 9 231 (SW) 4267 - 02:59Z 56 27 7 225 (SW) 4174 - 03:32Z 57 26 3 192 (SSW) 3487 - 04:02Z 57 26 4 199 (SSW) 2623 - 04:34Z 57 26 8 221 (SW) 2087 - 05:04Z 56 26 8 212 (SSW) 1794 - 05:36Z 57 26 9 232 (SW) 1623 - clouds 06:09Z 57 26 6 251 (WSW) 1608 - 06:41Z 56 25 8 210 (SSW) 1504 - 07:13Z 56 26 7 222 (SW) 1584 - 07:45Z 55 26 1 253 (WSW) 1600 - 08:17Z 56 25 6 290 (WNW) 1371 - 08:49Z 55 26 4 283 (WNW) 1503 - 09:22Z 54 26 7 349 (NNW) 1467 - 09:52Z 55 27 7 10 (N) 1432 - 10:22Z 55 27 11 14 (NNE) 1356 - 10:54Z 56 27 14 10 (N) 1268 - ---=== TELESCOPE STATUS ===--- 04:40Z Doors and louvers opened, fans on. 05:10Z Enclosure is off, spectro dewar is refilled. 10:45Z Enclosure is on, telescope is at stow (121,30,0), cart 8 (plate 2200) is mounted.
