Pan Night: M. Harvanek, E. Malanuskenko ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Most of night was clear, but the seeing was not good and we did spectroscopy. 4 plates are DONE and we obtained signal on one more plate. ---=== OBSERVING LOG ===--- Afternoon: Spectrograph focus checked and adjusted the best focus temp is around 2 C. As usual, details in problem section. 23:00Z Fans on, louvers open. 23:40Z east door open and west door craked. cart 1 (plt 2398) mounted. Night: Open telescope at 00:40Z. Weather - clouds around mountain. T=0.6C, wind is 16 mph up to 20 mph. The weather condition is not photometric. We are doing spectroscopy. Cart 1, plate 2398, seguefaint, pri=4. Previously obtained signal is 19.6. Used FK5 to find guider stars. Focus 250. Waiting for clouds go away. preCali 02:45:15b 2:00, 2:22, 2:45, 3:07 science, total todays' exposure time is 5100. 3:35 Postcal is requred and it is done. Todays' and MJD 53766 exposures are enough to declare this plate "DONE". Cart 6, plate 2401, seguefaint, pri=4. T=1.5C Used FK5 star to find guider stars. Seeing is 2.5, focus =100. 3:59 PreCal; 4:06, 4:33, 5:01, 5:30, 5:58 - science exposures 5:40 - efficiency is lower then 30%, and 5:30 is declared as bad. 6:26 - PostCal is requred and had been done. 6:32, 7:00, 7:28 - science exposures. Total science exposure time is 12300 sec. "DONE" Cart 3, plate 2372, chunk131, pri=3. Clear, T=0.8, wind 5 to 26 mph; focus=100; seeing=1.7, eff=70% Found guider stars on go to field. 8:11 - PreCalibration 8:18, 8:40, 8:59 - science exposures Total exposure time is 3200. "DONE" Cart 4, plate 2373, chunk, pri=3. Found guider stars on GoToField. Clear, T=0.5C, wind 9.5 to 26 mph; seeing is variable between 2 and 4, it is difficult to find focus. Eff is in the range 15-50%, scale 0.008 to -0.007. We are 5 min waiting for the stabilization of weather condition. Seeing is 2.5, focus=175. 9:43 PreCalibration. 9:50 science focus=125, seeing=1.7, eff=50-75% 10:12, 10:35 science. Total exposure time is 3900. "DONE" Cart 9, Plate 2144, chunk, pri=3 Found stars on GoToField Clear, T=-0.1C, seeing=2.1, focus=125, eff=70% 11:14 PreCalibration 11:22, 11:45, 12:07, 13:30 science 11:50 - clouds, efficiency is 30-50%, humidity is going up, 63. 12:30 - more clouds. 13:30 exposure is declared as bad. We did not obtain necessary signal and could not finish plate. "CONTINUE" Dimm stopped working around 3:00. Clouds 13:10 closed inclosure. No PT morning twilight, clouds. endNight is completed. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6008 22:30Z 22:48Z 100 O -181.17 -176.66 44 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): yes QA Procedures Done (y/n): yes UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 36946, plate 1989 ------- 22:29 36946 10.0 flat 22:32 36947 2.0 arc 22:37 36948 2.1 arc 22:40 36949 2.1 arc ----- sequence 36950, plate 2398 ------- 23:25 36950 10.0 flat 23:27 36951 2.0 arc 23:31 36952 2.1 arc 23:34 36953 2.1 arc 00:05 36954 0.0 bias ----- sequence 36955, plate -9999 ------- 00:41 36955 0.0 bias ----- sequence 36956, plate 2398 -------23.6 19.6 27.1 27.0 MJD 53766 01:55 36956 10.0 flat 33.5 30.7 40.0 41.9 today 01:58 36957 2.0 arc ---------------------------------- 02:22 36958 1200.1 target 50.3 "DONE" 02:44 36959 1200.2 target 03:07 36960 1200.1 target 03:34 36961 1500.2 target 03:37 36962 10.0 flat 03:40 36963 2.0 arc ----- sequence 36964, plate 2401 --------- 68.1 58.4 73.8 51.8 04:01 36964 10.0 flat "DONE" 04:03 36965 2.0 arc 04:33 36966 1500.1 target 05:00 36967 1500.1 target 05:28 36968 1500.1 target 05:57 36969 1500.1 target 06:25 36970 1500.1 target 06:28 36971 10.0 flat 06:30 36972 2.0 arc 06:59 36973 1500.1 target 07:27 36974 1500.1 target 08:00 36975 1800.1 target ----- sequence 36976, plate 2372 ------- 20.4 18.3 23.7 18.7 08:13 36976 10.0 flat "DONE" 08:16 36977 2.0 arc 08:40 36978 1200.1 target 08:59 36979 1000.1 target 09:18 36980 1000.1 target ----- sequence 36981, plate 2373 ------- 22.7 17.2 22.9 16.9 09:45 36981 10.0 flat "DONE" 09:48 36982 2.0 arc 10:12 36983 1200.1 target 10:34 36984 1200.1 target 11:02 36985 1500.1 target ----- sequence 36986, plate 2144 ------- 16.5 11.5 14.9 11.5 11:17 36986 10.0 flat "CONTINUE" 11:19 36987 2.0 arc 11:44 36988 1200.1 target 12:07 36989 1200.1 target 12:29 36990 1200.1 target 12:52 36991 1200.1 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:00Z 1 2398 257.98 -0.0062 79.33 0.0018 84.91 -0.0059 1.000280 03:59Z 6 2401 101.93 0.0019 45.04 0.0026 252.40 -0.0137 1.000170 08:18Z 3 2372 2.39 0.0012 76.28 0.0023 182.05 0.0306 1.000100 09:43Z 4 2373 -57.37 -0.0020 68.16 0.0014 131.22 -0.0047 1.000140 11:23Z 9 2144 71.75 0.0012 65.64 0.0028 239.77 0.0053 1.000100 ---=== 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 ------------------------------------------------------------------------------ 01:59Z 1 2398 1.00028 -2765 -920 250 258 79.4 0.7 18 278 -- 1.2 03:59Z 6 2401 1.00017 -1679 -91 100 102 45.0 0.8 16 297 -- 2.5 08:18Z 3 2372 1.00010 -988 405 100 3 76.3 0.7 17 295 -- 1.7 09:45Z 4 2373 1.00014 -1383 166 175 -58 67.9 0.2 9 330 -- 1.7 11:22Z 9 2144 1.00010 -988 448 125 72 65.5 -0.1 9 316 -- 2.1 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:24Z 38 10 15 286 (WNW) 470 - 22:55Z 36 10 6 269 (W) 425 - 23:28Z 35 10 15 266 (W) 470 - 23:59Z 36 10 17 268 (W) 474 - 00:32Z 34 10 20 263 (W) 512 - 01:19Z 33 15 14 267 (W) 1269 - 01:50Z 33 17 15 271 (W) 1728 - 02:21Z 33 16 16 285 (WNW) 1140 - 02:52Z 32 16 18 278 (W) 1011 - 03:22Z 34 16 22 293 (WNW) 825 - 03:53Z 33 18 18 299 (WNW) 826 - 04:24Z 34 17 14 326 (NW) 630 - 04:55Z 34 18 12 302 (WNW) 578 - 05:26Z 34 18 17 347 (NNW) 422 - 05:56Z 34 18 13 19 (NNE) 397 - 06:26Z 33 19 4 29 (NNE) 418 - 06:57Z 33 19 10 287 (WNW) 324 - 07:28Z 33 18 10 1 (N) 407 - 07:58Z 33 18 8 353 (NNW) 370 - 08:28Z 33 18 20 2 (N) 303 - 08:59Z 33 19 15 0 (N) 241 - 09:29Z 32 19 8 359 (NNW) 279 - 09:59Z 32 19 7 283 (WNW) 266 - 10:29Z 32 20 8 32 (NNE) 243 - 10:59Z 32 20 27 7 (N) 254 - 11:30Z 31 20 17 32 (NNE) 251 - 12:00Z 31 20 28 21 (NNE) 259 - 12:31Z 32 19 20 359 (NNW) 312 - 13:02Z 32 19 14 359 (NNW) 392 - 13:32Z 32 18 12 345 (NNW) 367 - ---=== TELESCOPE STATUS ===--- 23:00Z Fans on and louvers open 23:40Z east door open and weat door craked. 00:40Z Opened enclosure. 13:24Z Closed enclosure.
