APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday December 20, 2006 (MJD 54090) ---=== OBSERVING TEAM ===--- Howard Brewingon (Days) Kaike Pan and Dan Long (Observers) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We had high humidity all night, and with cold temperatures and all that fluffy white stuff that has fallen over the last 24 hours (somewhere between 6 and 8 inches), it isn't taking much of a breeze to blow it around. We never opened. ---=== OBSERVING LOG ===--- Afternoon: ----------- Watcher is still reporting that sp2's mechanicals as "Not connected." Spectro focus was checked and adjusted (-3000) to the temp of about -4.5-Degrees C. The focus numbers are posted in the Problems Section. Bob P. put two full dewars just inside the 2.5-meter enclosure. Night: ------ 00:00Z Clouds, Humidity, and blowing snow prevent us from opening. 04:55Z Rain sensor goes off, presumably due to blowing snow as there are almost no clouds in the sky. 11:00Z Humidity rules the night, along with periods of blowing snow and clouds. We call it quits. 11:13Z endNight quickly rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6633 22:17Z 22:51Z 100 O 132.89 141.32 65 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):n QA Procedures Done (y/n):n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 42064, plate -9999 ------- 22:20 42064 0.0 bias 22:30 42065 0.0 bias ----- sequence 42066, plate 2580 ------- 22:49 42066 10.0 flat 22:52 42067 2.0 arc 22:57 42068 2.0 arc 22:59 42069 3.0 arc ----- sequence 42070, plate -9999 ------- 23:36 42070 0.0 bias ----- sequence 42071, plate -9999 ------- 23:50 42071 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 ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 09:23Z 4 0 1.00000 0 1245 0 121 30.2 -7.9 13 318 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:55Z 19 16 15 323 (NW) 367 - Light Snow 22:25Z 19 15 11 265 (W) 375 - Light Snow 22:55Z 21 18 14 266 (W) 407 - Mostly Cloudy 23:25Z 19 16 10 261 (W) 488 - Snow Flurries 23:55Z 19 16 12 238 (WSW) 557 - Mostly Cloudy 00:27Z 18 15 13 239 (WSW) 556 - Mostly Cloudy 01:00Z 17 15 13 263 (W) 511 - Mostly Cloudy 01:32Z 18 15 14 293 (WNW) 492 - Mostly Cloudy 02:04Z 18 15 14 291 (WNW) 436 - Mostly Cloudy 02:36Z 18 15 16 296 (WNW) 438 - Mostly Cloudy 03:08Z 19 15 12 265 (W) 423 - Mostly Cloudy 03:40Z 19 16 16 273 (W) 406 - Partly Cloudy 04:12Z 18 15 17 285 (WNW) 382 - Partly Cloudy 04:45Z 18 15 14 286 (WNW) 346 - Mostly Clear 05:17Z 18 15 17 272 (W) 319 - Partly Cloudy 05:49Z 18 15 16 289 (WNW) 316 - Partly Cloudy 06:21Z 18 15 16 315 (NW) 362 - Mostly Clear 06:53Z 18 15 9 329 (NNW) 304 - Partly Cloudy 07:25Z 18 12 3 343 (NNW) 347 - Cloudy 07:57Z 17 14 15 344 (NNW) 331 - Partly Cloudy 08:29Z 17 14 12 311 (NW) 310 - Mostly Clear 09:02Z 17 14 7 324 (NW) 322 - Mostly Clear 09:34Z 17 14 8 311 (NW) 422 - Mostly Clear 10:06Z 16 13 16 329 (NNW) 281 - Mostly Clear 10:38Z 17 13 13 348 (NNW) 234 - Clear 11:10Z 17 13 15 354 (NNW) 272 - Clear ---=== TELESCOPE STATUS ===--- 11:15Z Enclosure never opened.
