APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday February 24, 2006 (MJD 53791) ---=== OBSERVING TEAM ===--- swing: Jurek Krzesinski night: Kaike Pan, Mike Harvanek ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds, high humidity, rain, fog, lightning, snow, high wind and "dust" which was probably fog. We got several inches of heavy, wet snow. The sky cleared and the humidity finally dropped but blowing snow kept us closed. The entire night was lost to weather. Snow removal. The monitor for ad4 is going bad. ---=== OBSERVING LOG ===--- Afternoon checkout: ------------------- No problems to report. Night: ------ Mostly cloudy with rising humidity half an hour before sunset. We stopped ventilating and closed everything up around 00:47Z. We had rain, fog and lightning shortly thereafter. This was followed by snow, wind gusts > 35 mph and "dust" which was probably fog. We got several inches of heavy wet snow. The clouds cleared around 05:25Z but the humidity remained high. The humidity dropped below 80% around 09:15Z but blowing snow was still a problem. We never opened. We shoveled snow from the ops building down to and around the plug plate lab and the 2.5m telescope. The monitor for ad4 is going bad. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6034 22:41Z 22:58Z 100 O -155.87 -151.58 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): YES QA Procedures Done (y/n): NO UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 37607, plate -9999 ------- 23:00 37607 0.0 bias ----- sequence 37608, plate 2418 ------- 23:09 37608 10.0 flat 23:11 37609 2.0 arc 23:14 37610 2.1 arc 23:17 37611 2.1 arc 23:30 37612 2.1 arc 23:32 37613 2.1 arc ----- sequence 37614, plate -9999 ------- 01:00 37614 0.0 bias 01:05 37615 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== 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 ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 20:58Z 40 32 17 239 (WSW) 478 - 21:30Z 44 34 16 242 (WSW) 606 - 22:02Z 42 31 14 261 (W) 542 - 22:34Z 42 30 11 238 (WSW) 557 - 23:05Z 42 31 14 218 (SW) 547 - 23:38Z 42 31 14 248 (WSW) 467 - 00:12Z 39 30 12 219 (SW) 425 - 00:44Z 37 31 20 235 (SW) 818 - mostly cloudy 01:26Z 36 33 25 217 (SW) 815 - rain, fog, lightning 01:56Z 35 31 21 220 (SW) 601 - 02:26Z 29 29 12 341 (NNW) 954 - 02:59Z 28 28 18 327 (NNW) 1910 - 03:31Z 29 29 14 265 (W) 1309 - snow 04:03Z 29 29 14 326 (NW) 4609 - 04:35Z 29 29 16 298 (WNW) 8274 - 05:07Z 29 29 18 348 (NNW) 7466 - 05:40Z 29 28 12 22 (NNE) 298 - clear, blowing snow 06:12Z 29 28 7 336 (NNW) 324 - 06:44Z 29 27 12 357 (NNW) 372 - 07:16Z 30 26 4 323 (NW) 385 - 07:49Z 30 26 4 6 (N) 487 - 08:21Z 30 26 4 24 (NNE) 417 - 08:53Z 30 25 12 324 (NW) 478 - 09:25Z 31 25 3 355 (NNW) 458 - 09:57Z 31 23 11 350 (NNW) 443 - 10:30Z 30 21 1 0 (N) 446 - 11:02Z 31 21 7 354 (NNW) 450 - 11:34Z 31 21 9 325 (NW) 503 - ---=== TELESCOPE STATUS ===--- 23:53Z Enclosure doors opened, fans and blowers on, louvers opened. 00:47Z Doors closed, fans and blowers off, louvers closed (clouds + humidity).
