APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday June 11, 2007 (MJD 54263) ---=== OBSERVING TEAM ===--- Kaike Pan Dmitry Bizyaev Shannon Watters ---=== OBSERVING PLAN ===--- Appease the rain gods. ---=== OBSERVING SUMMARY ===--- Most of night was lost to rain, high hunmidity. We opened for the last one hour and finished one plate: 2554. ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working. Spectrograph focus set to ~13C (no adjustments). Night: ----- It was raning till 5:30Z, then high humidity. During the period time, lightnight threadthening kept us from do imager monthly checkout. 08:55Z started ventilation. We noticed that there are 3 to 4 C difference between 2.5m and 3.5m weather station reported temperature before we started ventilation. 09:20Z enclosure off. 09:25Z cart 8, plate 2554. took a test pre-calib to make sure spectrographs are still in focus because we are about 5.5C below focus setting temperature. The test preCalib was good, and declared test. 09:50Z pre-calib. During the pre-calib exposure, we had a power glitch, the telescope stoped tracking. We could not find stars. Two axis init clear the axis, then we went to field again. 10:10Z, started a 20-min exposure. We took the first set of post-calib (frame # 45296 and 54297) with guider running. It maybe okay because FF screen was closed for post-calib. But for safete, we took another set of post-calib (frame #45298 and 45299). The plate was DONE combined with signals got in mjds: 54261, 54262. 11:20Z endNight finished ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6847 23:12Z 23:30Z 100 O -42.91 -38.26 45 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 45283, plate -9999 ------- 23:14 45283 0.0 bias ----- sequence 45284, plate 2554 ------- 23:19 45284 10.0 flat 23:21 45285 2.0 arc 23:24 45286 3.0 arc 23:27 45287 2.0 arc ----- sequence 45289, plate -9999 ------- 01:25 45289 0.0 bias 01:29 45290 0.0 bias ----- sequence 45291, plate 2554 ------- 9.6, 5.1, 8.1, 2.6 09:27 45291 10.0 flat 09:29 45292 2.0 arc 10:00 45293 10.0 flat 10:03 45294 2.0 arc 10:33 45295 1200.0 target 10:36 45296 10.0 flat 10:38 45297 2.0 arc 10:43 45298 10.0 flat 10:46 45299 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 10:20Z 8 2554 187.10 0.0002 62.39 0.0001 11.90 -0.0147 1.000250 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 10:20Z 8 2554 1.00025 -2469 -677 220 187 62.4 7.6 17 282 -- 1.7 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:11Z 51 49 11 219 (SW) 3562 - cloudy 22:43Z 51 48 12 201 (SSW) 5468 - cloudy 23:14Z 49 47 11 270 (W) 4747 - cloudy 23:44Z 48 44 7 296 (WNW) 4127 - 01:45Z 44 45 12 314 (NW) 641 - 02:17Z 45 45 7 267 (W) 4346 - 02:49Z 45 45 1 160 (SSE) 92 - 03:21Z 45 43 12 258 (WSW) 137 - 03:53Z 45 41 11 226 (SW) 146 - 04:25Z 44 44 3 252 (WSW) 181 - 04:58Z 45 44 9 250 (WSW) 128 - 05:30Z 44 44 9 261 (W) 220 - 06:02Z 43 43 12 254 (WSW) 129 - 06:34Z 43 43 15 248 (WSW) 3165 - 07:06Z 43 43 8 287 (WNW) 240 - 07:38Z 43 41 6 291 (WNW) 294 - 08:10Z 42 40 11 348 (NNW) 367 - 08:43Z 44 38 9 317 (NW) 288 - cloudy 09:15Z 45 38 11 301 (WNW) 293 - mostly cloudy 09:45Z 45 36 12 294 (WNW) 230 - mostly clear 10:15Z 45 36 15 280 (W) 233 - clear 10:46Z 45 36 15 273 (W) 295 - 11:19Z 44 38 13 272 (W) 256 - clear ---=== TELESCOPE STATUS ===--- 08:55Z - Began ventilation.
