No problems to report. ---=== OBSERVING LOG ===--- Afternoon: ---------- A change was made to the spectro focus so that it should be set for an air temp of about 3 or 4 C. Axial B on M1 wa a little out of spec yesterday. Today, it is better but marginal. I don't think we need to home and relax M1 yet, but we shold monitor it. No data were deleted from sdsshost2/sdssfiles1 The azimuth axis aborted a few degrees into it's test slew, but after re-initialization, it was fine. No other problems noted. 23:45Z - Started ventilation. Night: ----- 00:23Z - Stopped ventilating. High humidity and lots of clouds. 03:00Z - Clouds disappated, but humidity still at 85%, dew point 2.2. 04:15Z - Swapped out imager dewer. 11:01Z - Dew point different rose to 3.0-3.2. We decided to mount cart 4, plate 3170 and start ventilating just in case the weather improved. 11:18Z - Dew point dropped again. We stopped ventilating. 11:45Z - Humidity at 87.5%, dew point at 1.8. Weather did not improve. We called it a night. 12:00Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7930 22:39Z 22:53Z 100 O 173.36 -183.29 36 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 22:51 58375 3.0 arc 22:54 58376 3.0 arc 23:19 58377 3.0 arc 23:22 58378 3.0 arc 23:34 58379 10.0 flat 23:37 58380 2.0 arc ----- sequence 58381, plate -9999 ------- 00:44 58381 0.0 bias ----- sequence 58382, plate -9999 ------- 01:45 58382 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 ------------------------------------------------------------------------------ 23:49Z 6 0 1.00000 1 1140 0 121 88.9 2.7 11 266 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:52Z 40 31 11 289 (WNW) 589 - Cloudy, humid 23:23Z 38 31 11 245 (WSW) 740 - " 23:54Z 37 31 10 257 (WSW) 852 - " 00:29Z 36 31 10 254 (WSW) 1087 - "" 00:59Z 36 31 11 255 (WSW) 1247 - " 01:29Z 36 31 16 254 (WSW) 1372 - " 02:01Z 36 31 11 261 (W) 788 - " 02:33Z 35 31 10 258 (WSW) 699 - " 03:05Z 35 31 10 260 (W) 531 - Clear, humid 03:37Z 35 31 9 253 (WSW) 376 - " 04:10Z 35 31 12 267 (W) 371 - " 04:42Z 35 31 11 262 (W) 341 - " 05:14Z 34 31 14 265 (W) 347 - " 05:46Z 35 31 14 255 (WSW) 341 - " 06:18Z 35 30 16 266 (W) 304 - " 06:50Z 34 29 16 266 (W) 332 - " 07:22Z 34 30 18 265 (W) 318 - " 07:55Z 34 31 17 262 (W) 348 - " 08:27Z 34 30 20 270 (W) 381 - " 08:59Z 33 29 17 264 (W) 374 - " 09:31Z 32 30 10 265 (W) 344 - " 10:03Z 33 30 12 265 (W) 401 - " 10:35Z 33 28 15 276 (W) 388 - " 11:07Z 33 28 14 271 (W) 458 - " 11:40Z 32 29 11 273 (W) 467 - " ---=== TELESCOPE STATUS ===--- 23:45Z - Began ventilation.
