APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday May 7, 2006 (MJD 53863) ---=== OBSERVING TEAM ===--- Kaike Pan ET crew: Jian Ge, Scott Fleming Support: Howard Brewington ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- A another wonderful night: photometric whole night with relatively good seeing 1.1-1.4". We obtained one 50-min exposure for each of the 8 ET plates. Dust levels were from 2600 to 3100. Integrated dust counts was about 29K for tonight. Through this weekends (5/5 -- 5/7), we accumulated a total 79 K dust-count-hours. Mirrors need to be clean, I guess! Problem: No guiding star infor for fiber #6 was read when loading plate 8028 - see log. Can somebody check and fix this? ---=== OBSERVING LOG ===--- afternoon: ---------- Everything was good. Dust count at 01:30Z was 2.6K. ET calibration for the begining of the night was done. night: ------ 02:15Z cart 8, plt 8024. using last night's offsets to get stars. at 02:25Z, we were ready to go and let ET crew to decide when they want to start the exposure. One 50 min exposure. 03:35Z cart 9, plt 8025. adapting last night's offsets (+8,-2) to get stars. one 50 min expaosure. 04:40Z cart 4, plt 8026. Using offsets (-9, -2) to get stars. one 50 min exposure. 05:45 ET midnight calibration. 05:58Z cart 6, plt 8021. offsets: (-6, -3). one 50-min exposure. Seeing was not stable as it one hours ago. It varied from 1.2 to 1.7. 07:05Z cart 7, plt 8022. stars on GTF. one 50-min exposure. 08:10Z cart 2, plt 8027. stars on GTF. one 50-min exposure. seeing was variable, maybe slightly worse than a few hour ago. 09:13Z cart 5, plt 8029. stars on GTF. one 50-min exposure. 10:16Z cart 3, plt 8028. stars on GTF. ome 50-min exposure. When loading cartridge, we got the following message: Found No Guide Stars for fiber ID 6 Coordinates are 285.05313000000001 45.203682999999998 11:40Z endNight rejoiced. ---=== 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 ----- sequence 39119, plate -9999 ------- 00:33 39119 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:09Z 8 8024 -46.08 -0.0046 70.23 0.0022 140.32 0.0309 1.000150 03:55Z 9 8025 -4.74 0.0001 59.96 0.0009 175.92 0.0105 1.000130 04:57Z 4 8026 165.42 0.0062 68.13 0.0018 -21.02 0.0001 1.000100 06:10Z 6 8021 84.92 0.0035 66.29 0.0033 251.03 0.0046 1.000160 07:12Z 7 8022 115.06 0.0034 73.29 0.0032 -76.44 0.0057 1.000120 08:17Z 2 8027 121.06 0.0030 58.99 0.0027 -82.77 0.0077 1.000120 09:22Z 5 8029 104.88 0.0015 68.53 0.0022 -89.95 -0.0035 1.000000 10:56Z 3 8028 178.06 0.0027 77.53 0.0005 -2.46 0.0238 1.000050 ---=== 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 ------------------------------------------------------------------------------ 03:09Z 8 8024 1.00025 -2469 -853 60 -46 70.2 10.8 7 256 -- 1.3 03:55Z 9 8025 1.00013 -1284 90 0 -5 60.0 10.8 14 238 -- 1.2 04:57Z 4 8026 1.00010 -988 328 10 165 68.1 10.4 17 238 -- 1.4 06:10Z 6 8021 1.00016 -1580 -194 -25 85 66.3 10.3 11 269 -- 1.3 07:12Z 7 8022 1.00012 -1185 156 10 115 73.3 9.7 10 266 -- 1.3 08:17Z 2 8027 1.00012 -1185 184 10 121 59.0 9.8 10 287 -- 1.4 09:22Z 5 8029 1.00000 0 1084 -50 105 68.5 9.2 6 267 -- 1.3 10:57Z 3 8028 1.00005 -494 702 -10 178 77.5 9.1 4 355 -- 1.4 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:20Z 57 12 16 270 (W) 2472 - clear 00:52Z 57 13 14 259 (W) 2391 - clear 01:24Z 54 11 12 262 (W) 2757 - clear 01:57Z 52 8 17 252 (WSW) 2629 - clear 02:29Z 51 8 13 257 (WSW) 2671 - clear 03:01Z 51 10 13 255 (WSW) 2720 - clear 03:33Z 51 10 12 251 (WSW) 2752 - clear 04:05Z 51 10 13 243 (WSW) 2660 - clear 04:37Z 50 9 15 257 (WSW) 2639 - clear 05:08Z 51 8 11 264 (W) 2661 - clear 05:41Z 50 9 14 264 (W) 2465 - clear 06:14Z 50 10 16 266 (W) 2462 - clear 06:46Z 50 11 13 267 (W) 2606 - clear 07:18Z 49 13 11 265 (W) 2677 - clear 07:50Z 49 14 11 269 (W) 2592 - clear 08:22Z 49 15 6 274 (W) 2850 - clear 08:54Z 48 16 7 269 (W) 2768 - clear 09:25Z 48 16 5 266 (W) 2709 - clear 09:55Z 48 16 1 309 (NW) 2703 - clear 10:25Z 48 17 3 338 (NNW) 2951 - clear 10:57Z 48 16 4 355 (NNW) 2887 - clear 11:29Z 49 15 3 26 (NNE) 2780 - ---=== TELESCOPE STATUS ===--- 01:10Z Doors and louvers opened, fans on. 01:40Z enclosure off. 11:30Z enclosure on, door and louvers closed, fans off.
