The passage of a strong cold front gave us high winds, high humidity and fog. When it was obvious that conditions were not going to improve we ran imager cals, getting QE data for r1. ---=== OBSERVING LOG ===--- Afternoon --------- Per instructions from this afternoon's DA phonecon, we 1) stopped the copyUnstoredFilesInIdReport script Dan started at the end of last night, 2) rebooted the photo and astro crates, 3) checked (and found) available space in the pool and 4) took a bias (Run 5659) to verify that the archiver was running again. Once satisfied on (4), we restarted the script to continue archiving files from last night. No issues during checkout. Spectro focus was set for airTemp = 10 deg C; details in Problems section. Night ----- 01:00Z High winds, and rain just to our north dictate a delay to opening. 01:30Z The copyUnstoredFilesInIdReport from last night finished. endNight was then finally run for 53641. 02:30Z We can add high humidity to the list of bad weather. 06:00Z Conditions not changing much (if anything they are worse). So we are going to try taking some imager cals. We created /data/photo/doi/calibdata as that appears to be where the scripts expect to put the data. Run 5660 is QE data for r1. Levels in the frames vary from bias to about 24000 counts in the brightest frames. 11:00Z endNight ran successfully tonight, twice! ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5659 21:11Z 21:21Z 100 O 34.73 37.13 29 ignore Test of archiver health 5661 09:43Z 10:06Z 100 O -136.68 -130.93 53 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 ----- sequence 34084, plate -9999 ------- 21:12 34084 0.0 bias 21:23 34086 0.0 bias 21:29 34087 0.0 bias ----- sequence 34088, plate 2258 ------- 22:18 34088 10.0 flat 22:20 34089 2.0 arc 22:23 34090 2.1 arc 22:25 34091 2.1 arc 22:43 34092 2.1 arc 22:45 34093 2.1 arc ----- sequence 34094, plate -9999 ------- 00:54 34094 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 21:00Z 63 36 10 114 (ESE) -9999 - Mostly Cloudy 21:32Z 63 37 9 128 (SE) -9999 - Mostly Cloudy 22:03Z 62 41 14 84 (E) -9999 - Partly Cloudy 22:34Z 62 43 9 94 (E) -9999 - Partly Cloudy 23:05Z 60 43 9 98 (E) -9999 - Mostly Cloudy 23:35Z 61 43 16 112 (ESE) -9999 - Partly Cloudy 00:05Z 60 43 14 84 (E) -9999 - Mostly Cloudy 01:00Z 56 46 30 72 (ENE) -9999 - Mostly Cloudy 01:32Z 55 48 21 73 (ENE) -9999 - Cloudy 02:04Z 53 49 20 82 (E) -9999 - Cloudy 02:36Z 52 49 26 84 (E) -9999 - Cloudy 03:08Z 48 49 28 77 (ENE) -9999 - Fog 03:45Z 48 49 23 84 (E) -9999 - Fog 04:17Z 47 48 31 72 (ENE) -9999 - Fog 04:49Z 46 47 25 87 (E) -9999 - Fog 05:21Z 45 46 38 77 (ENE) -9999 - Fog 05:53Z 45 45 24 76 (ENE) -9999 - Partly Cloudy 06:25Z 45 45 32 84 (E) -9999 - Partly Cloudy 06:58Z 44 45 27 87 (E) -9999 - Sprinkles 07:30Z 43 45 32 83 (E) -9999 - Fog 08:02Z 42 44 27 89 (E) -9999 - Fog 08:34Z 41 43 30 90 (E) -9999 - Fog 09:06Z 42 43 25 86 (E) -9999 - Fog 09:38Z 41 43 26 78 (ENE) -9999 - Fog 10:15Z 41 42 21 89 (E) -9999 - Sprinkles 10:47Z 40 41 19 78 (ENE) -9999 - Fog 11:19Z 40 41 17 93 (E) -9999 - Fog ---=== TELESCOPE STATUS ===--- Enclosure never opened.
