APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday October 4, 2006 (MJD 54013) ---=== OBSERVING TEAM ===--- Observer: Howard Brewington ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- The cloudCam is unhappy; see log. Found a few other problems during afternoon checkout. Humidity had us closed for about five hours. Completed plates 8029, 8033, 8031, and 8018. ---=== OBSERVING LOG ===--- Afternoon: ------------ I noticed a few problems during the afternoon checkout. 1) A rat had used some paper towels to make a home in the bottom of the cartirdge bay. It's on the northeast side under the end of the scissor jack. 2) The 2.5-meter enclosure made a loud (bang! bang! bang!) noise when I opened tonight. The noise was coming from the wheel area on the northeast end of the building. 3) The southwest building pin of the 2.5-meter enclosure had come free of its retaining cable. Night: ----------- Because of the spectro autoFill-system repairs, the 2.5-meter's balance had changed. The counterWeight's setting for spectro was ~200 lbs. Steph declared IOP current, viz., NOCVS:v4_26_0a:/linuxp/prd/iop/v4_26_0a I updated the white board. The cloudCam did not seem to be working tonight. The image looked very weak. I also noticed that the skyLevel setting was now at a level that was less than half of my setting a few nights ago. Although I tried playing with the focus, skyLevel and gain, I realized no improvement. Could this be a chopper wheel problem? 01:36Z Cart 05, plate 8029. Guide stars found with goToField. The seeing is about 2.3" We completed two 50-minutes exposures before closing because of high humidity, 03:50Z We closed and waited. 08:35Z Enclosure off, louvers opened, fans on. 08:50Z Cart 01, plate 8033. Guide stars found with goToField. One 50-minute exposure was completed. 10:04Z Cart 07, plate 8031. Guide stars found with goToField. One 50-minute exposure was completed. 11:16Z Cart 02, plate 8018. Field was found with fK5 star. This 50-minute was cut about 5 minutes short because we had to close. (high humidity) 11:55Z closed, fans off Misc Watcher messages are posted in the Prbolems Section endNight finished and was happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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 ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:13Z 5 8029 252.54 0.0060 77.55 -0.0000 80.69 -0.0004 1.000060 08:57Z 1 8033 -31.64 0.0023 68.12 0.0023 152.97 -0.0030 1.000330 10:11Z 7 8031 -48.09 0.0006 73.62 -0.0010 137.82 -0.0096 0.999960 ---=== 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 ------------------------------------------------------------------------------ 02:13Z 5 8029 1.00006 -593 780 150 253 77.5 10.2 22 73 gdr 2.3" 08:57Z 1 8033 1.00033 -3259 -1513 50 -32 68.1 9.3 22 71 gdr 2.3" 10:11Z 7 8031 0.99996 395 1552 100 -48 73.6 9.0 12 86 gdr 2.3" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:25Z 58 38 10 131 (SE) 732 - 21:57Z 58 38 11 84 (E) 681 - 22:30Z 58 38 17 76 (ENE) 701 - 23:02Z 57 39 21 72 (ENE) 648 - 23:34Z 56 40 19 78 (ENE) 684 - 00:06Z 55 40 20 68 (ENE) 722 - 00:38Z 53 41 19 77 (ENE) 797 - 01:10Z 52 42 24 69 (ENE) 1075 - 01:42Z 51 42 21 75 (ENE) 1114 - 02:13Z 50 42 22 73 (ENE) 1161 - 02:47Z 50 43 17 72 (ENE) 1176 - 03:19Z 50 45 33 70 (ENE) 1064 - 03:51Z 50 45 20 79 (E) 1263 - 04:23Z 50 46 25 75 (ENE) 1056 - 04:56Z 49 46 17 83 (E) 1005 - 05:28Z 49 46 23 80 (E) 917 - 06:01Z 49 46 16 81 (E) 944 - 06:33Z 49 46 21 72 (ENE) 912 - 07:05Z 49 46 21 86 (E) 912 - 07:37Z 48 46 20 78 (ENE) 802 - 08:10Z 49 42 17 86 (E) 664 - 08:42Z 49 40 18 79 (E) 550 - 09:13Z 48 41 20 73 (ENE) 614 - 09:45Z 48 39 19 85 (E) 595 - 10:16Z 48 37 16 83 (E) 602 - 10:46Z 47 38 11 93 (E) 551 - 11:19Z 47 39 17 73 (ENE) 505 - 11:51Z 46 41 17 90 (E) 557 - ---=== TELESCOPE STATUS ===--- 23:30Z Doors and louvers open, fans on. 00:45Z Enclosure off. 03:50Z Enclosure on, doors and louvers closed, fans off.
