APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday October 25, 2009 (MJD 55130) ---=== OBSERVING TEAM ===--- Kaike Pan Dmitry Bizyaev ---=== OBSERVING PLAN ===--- MARVELS till ~06:26Z, then BOSS spectroscopy or imaging ---=== OBSERVING SUMMARY ===--- The night is lost due to high humidity, rain and snow. A gauge at the southern side of the mount, in the lower enclosure signed as "spectrograph pressure", is low: shows 15, should be 22. Unclear if it is related to old spectrograph or to the new one. Observer's phone device in the control room works awry: hard to hear anything because of strong background noise. We left spectro dewar below 100 lb, please check it in the morning. ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:02Z Th-Ar lamp turned on imager bias ok boss sp bias taken guider dark 20 sec taken 23:20Z started ventilation We are delaying with opening because of clouds and close radar return. Night: ------ 01:30Z rain. Rain sensor delayed, we got a few drips on cloud camera. Stopped ventilation. Rain. Snowfall after ~04Z. Sky is getting partly clear but humidity is high after ~ 07:10Z 10:00Z Same situation with humidity. 11L30Z endNight finished. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 8127 23:49Z 00:36Z 100 O 100.98 112.70 92 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 ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:43Z 46 20 12 299 (WNW) 393 - 22:15Z 46 21 3 304 (NW) 406 - 22:47Z 45 21 1 349 (NNW) 423 - 23:20Z 45 21 0 280 (W) 428 - 23:52Z 44 22 0 106 (ESE) 414 - 00:25Z 44 21 1 227 (SW) 428 - 00:57Z 44 21 6 129 (SE) 480 - 01:29Z 43 25 12 220 (SW) 397 - 02:01Z 39 28 4 47 (NE) 1052 - 02:33Z 34 32 14 59 (ENE) 653 - 03:05Z 33 32 16 66 (ENE) 244 - 03:37Z 32 31 14 76 (ENE) 105 - 04:10Z 32 31 3 13 (NNE) 53 - 04:42Z 32 31 2 88 (E) 184 - 05:14Z 33 30 1 128 (SE) 178 - 05:46Z 33 31 9 120 (ESE) 254 - 06:18Z 34 30 2 124 (SE) 254 - 06:50Z 35 28 2 332 (NNW) 278 - 07:22Z 35 29 0 305 (NW) 286 - 07:55Z 31 29 9 63 (ENE) 85 - 08:27Z 30 29 7 78 (ENE) 641 - 08:59Z 30 30 8 79 (E) 127 - 09:31Z 29 29 5 79 (E) 309 - 10:03Z 30 29 2 86 (E) 107 - 10:35Z 32 31 1 351 (NNW) 178 - 11:07Z 28 27 12 69 (ENE) 127 - ---=== TELESCOPE STATUS ===--- 23:20Z - Began ventilation.
