APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday June 22, 2006 (MJD 53909) ---=== OBSERVING TEAM ===--- Days: Dan Long Night: John Barentine Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The night was lost to high humidity, clouds, and/or dust. We never opened. The motor on the west door of the 2.5-meter enclosure sounds unhappy. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems with the afternoon check. Spectro focus was checked and changed, best focus about 14 C. See problems section for details. Several bouts of thunderstorms in the late afternoon and early evening. Rain sensor is disabled. 00:40Z PT dewpoint sensor dewpoint value flatlines to zero (was properly reading above zero previously). Temperature value still OK. Night: ------ 02:14Z Clouds and rain at sunset, so we waited. 05:09Z Cracked doors, opened louvers, turned on fans, and rain sensor enabled. 05:52Z Closed doors and louvers, fans off as humidity went over the limit. 10:00Z We went to bed endNight finished and was happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6221 21:42Z 21:51Z 100 O -54.30 -52.13 26 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): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 39919, plate -9999 ------- 21:44 39919 0.0 bias ----- sequence 39920, plate 2547 ------- 21:50 39920 10.0 flat 21:52 39921 2.0 arc 21:58 39922 2.1 arc 22:00 39923 2.1 arc 22:24 39924 2.1 arc 22:27 39925 2.1 arc 23:00 39926 10.0 flat 23:02 39927 2.0 arc ----- sequence 39928, plate -9999 ------- 00:17 39928 0.0 bias 00:56 39929 0.0 bias 00:59 39930 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 ------------------------------------------------------------------------------ 00:57Z 5 0 1.00000 0 1257 0 121 30.0 12.1 17 109 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 20:36Z 65 44 5 93 (E) 8295 - Mostly Cloudy 21:12Z 61 42 11 90 (E) 7176 - Mostly Cloudy 21:43Z 58 40 25 67 (ENE) 4418 - Thunder 22:13Z 53 41 15 79 (E) 3949 - Thundershower 22:44Z 53 42 28 69 (ENE) 3352 - Light Rain 23:15Z 54 45 16 85 (E) 3516 - Thunder 23:47Z 55 45 27 67 (ENE) 3918 - Thunderstorm 00:17Z 52 45 16 41 (NE) 4692 - Thunderstorm 00:48Z 51 47 16 4 (N) 3727 - Rain 01:18Z 52 45 19 83 (E) 2628 - Light Rain 01:46Z 52 44 17 124 (SE) 2335 - 02:18Z 51 43 21 137 (SE) 2178 - 02:50Z 52 43 25 149 (SSE) 2441 - 03:22Z 53 43 19 127 (SE) 1626 - 03:55Z 56 39 7 120 (ESE) 1829 - 04:27Z 54 41 13 121 (ESE) 1961 - 04:59Z 56 39 12 84 (E) 1945 - 05:29Z 51 43 21 73 (ENE) 1896 - 05:59Z 49 45 18 74 (ENE) 2465 - 06:30Z 52 44 10 85 (E) 4034 - 07:02Z 49 45 14 83 (E) 3680 - 07:35Z 49 45 12 81 (E) 3454 - 08:07Z 48 47 17 78 (ENE) 6349 - 08:39Z 48 46 16 75 (ENE) 4860 - 09:12Z 48 47 11 84 (E) 5210 - ---=== TELESCOPE STATUS ===--- 05:10Z Doors cracked, louvers opened, fan on.
