APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday June 27, 2003 (MJD 52818) ---=== OBSERVING TEAM ===--- night: Howard Brewington Jurek Krzesinski Jon Brinkmann (by phone) Wendell Jordan (by phone) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Spectro night: ---------------- One plate was declared done: Cart 04, Plate 1023 And, signal on two plates: Cart 08, Plate 1352 Cart 09, Plate 1033 ---=== OBSERVING LOG ===--- Afternoon: ---------- During the afternoon checkout, we noticed in the MCP menu that the Az fiducials was not being properly read, in fact, no Az fiducials were being read. After talking with Jon Brinkmann by phone and receiving the necessary cleaning instructions, we cleaned the fiducial reader on that axis, which restored its operation. We gave the blue camera on spectrograph 2 a minor focus tweak. Details are in the problems section. +++++++++++++++++++++++++++++++++++++++++++ Night: -------- We were closed during the beginning of the night because of clouds, but opened at 05:50Z. Some clouds were still in the area, so be started with spectro. Spectro: 06:00Z Cart 08, Plate 1352. Used an Fk5 star to find the field. Seeing was ~1.9" Completed one exposure before plate expired for the night. 07:18Z Cart 04, Plate 1023 (photo_z plate). Because of thin clouds, Fk5 star was used to find field. Seeing was ~2.0" When combined with signal from previous night, this plate was declared in three exposures. 09:08Z Cart 09, Plate 1033 (photo_z plate). Stars on slew. We still have variable conditions with respect to clouds. Seeing ~1.5" We completed three exposures but were unable to declare this plate done. endNight finished and was very happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4017 00:18Z 00:35Z 100 O -10.60 -6.25 43 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 21560, plate -9999 ------- 00:12 21560 0.0 bias ----- sequence 21561, plate -9999 ------- 00:56 21561 0.0 bias ----- sequence 21562, plate 1033 ------- 02:39 21562 10.0 flat 02:41 21563 2.0 arc 02:46 21564 2.1 arc 02:48 21565 2.1 arc 03:01 21566 2.1 arc 03:04 21567 2.1 arc ----- sequence 21568, plate -9999 ------- 03:39 21568 0.0 bias ----- sequence 21569, plate 1352 ------- 06:15 21569 10.0 flat 06:18 21570 2.0 arc 06:58 21571 1500.1 target ----- sequence 21572, plate 1023 ------- 07:35 21572 10.0 flat 07:37 21573 2.0 arc 08:12 21574 1800.1 target 08:35 21575 1200.1 target 08:51 21576 793.2 target 08:59 21577 240.0 smear ----- sequence 21578, plate 1033 ------- 09:12 21578 10.0 flat 09:15 21579 2.0 arc 09:34 21580 900.1 target 09:52 21581 900.1 target 10:11 21582 749.0 target 10:33 21583 900.1 target 10:41 21584 240.0 smear ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 06:44Z 8 1352 250.41 0.0048 53.19 0.0014 97.00 -0.0036 1.000070 07:45Z 4 1023 43.26 0.0018 48.52 0.0007 215.10 0.0055 0.999930 09:20Z 9 1033 36.03 0.0015 51.44 -0.0001 209.57 0.0124 0.999950 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL6602 Stays: JL6603 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 06:44Z 8 1352 1.00007 -690 298 -300 250 53.3 13.8 3 260 gdr 1.9 07:46Z 4 1023 0.99993 690 1458 -300 43 48.7 13.8 3 258 gdr 2.0 09:19Z 9 1033 0.99995 493 1285 -300 36 51.4 12.6 6 188 gdr 1.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:15Z 64 42 7 262 (W) 903 - clouds 23:48Z 63 42 10 292 (WNW) 897 - clouds 00:20Z 62 40 12 262 (W) 1116 - clouds 00:52Z 51 43 11 12 (NNE) 1234 - clouds 01:24Z 53 42 8 186 (S) 817 - clouds 01:57Z 53 40 20 149 (SSE) 725 - clouds 02:29Z 52 43 13 175 (S) 312 - clouds 03:05Z 56 36 15 246 (WSW) 360 - clouds 03:35Z 55 37 15 232 (SW) 456 - clouds 04:06Z 54 39 16 220 (SW) 476 - clouds 04:36Z 54 39 15 180 (S) 507 - clouds 05:06Z 52 39 6 120 (ESE) 581 - clouds 05:36Z 54 38 2 87 (E) 590 - clouds 06:06Z 57 34 3 258 (WSW) 439 - thin clouds 06:36Z 57 35 1 242 (WSW) 450 - thin clouds 07:07Z 57 34 5 271 (W) 427 - thin clouds 07:37Z 57 35 3 262 (W) 382 - thin clouds 08:07Z 57 34 0 233 (SW) 396 - thin clouds 08:37Z 56 34 4 222 (SW) 430 - thin clouds 09:08Z 55 36 7 215 (SW) 410 - thin clouds 09:38Z 54 36 9 191 (S) 351 - thin clouds 10:09Z 52 37 9 179 (S) 375 - thin clouds 10:40Z 51 37 11 154 (SSE) 360 - thin clouds ---=== TELESCOPE STATUS ===--- 02:30Z Fans on 03:15Z Doors open 05:50Z Enclosure off 10:50Z Enclosure on, fans off, shut down.
