APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday January 9, 2007 (MJD 54110) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Howard Brewington Mike Harvanek (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Variable clouds and seeing with lots of moonlight. Completed plates 2540 and 2634. Obtained signal on two other plates. ---=== OBSERVING LOG ===--- Afternoon: ---------- The 90 degree alt fiducial did not read in either direction. Spectro collimation was adjusted. The details are in the Problems section. Nothing else to report. Night: ---------- 00:11Z High thin clouds at sunset. 01:04Z Cart 03, plate 2634 (boaTest157). Found guide stars on goToField. Seeing as reported by the DIMM was ~1.2" as clouds increased. Although the first exposure was bad, the plate was declared done by adding tonight's S/N^2 to previous nights's. See below: MJD b1 r1 b2 b1 54110 18.1 13.0 15.2 15.8 54109 5.5 6.0 6.5 8.2 54108 9.1 7.6 9.4 10.2 ----------------------------- Total 32.7 26.6 31.1 34.2 03:05Z Cart 06, plate 2639 (boaTest157). Guide stars on goToField. Seeing as reported by the DIMM was ~0.75" The clouds became less of a problem. 05:06Z Cart 02, plate 2540 (segue146). Guide stars on goToField. Seeing as reported by the DIMM = ~1.0" and the sky is photometric. 05:41Z Seeing changed to about 1.7" Completed three exposure, and this plate was declared done. 06:40Z Cart 08, plate 2670 (segue158). Guide stars on goToField. Seeing as reported by the DIMM = ~1.2" and the sky is photometric. 09:00Z High, thin clouds moved over the site. 11:22Z Cart 09, plate 2102 (chunk100). Guide stars on goToField. Seeing as reported by the DIMM = ~1.5" and the sky had thin, high clouds. Captured one bad exposure. 12:14Z We went home because of clouds and moonlight. Misc Watcher reports are posted in the Problems Section, but the problem report that will just NOT go away is the sp1's mechanicals, viz., "Not Connected." The output of apo_plotbias is also posted in the Problems Section. When doing the QATopTen checks, I discovered that apoPlot is working okay tonight. endNight finished and was happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6667 21:59Z 22:14Z 100 O 147.98 151.80 40 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 42394, plate -9999 ------- 21:45 42394 0.0 bias 21:53 42395 0.0 bias ----- sequence 42396, plate 2670 ------- 22:49 42396 10.0 flat 22:52 42397 2.0 arc 23:10 42398 10.0 flat 23:12 42399 2.0 arc 23:26 42400 0.0 bias ----- sequence 42401, plate 2634 ------- 01:12 42401 10.0 flat 01:14 42402 2.0 arc 02:01 42403 1200.0 target 02:29 42404 1502.0 target 02:56 42405 1500.0 target ----- sequence 42406, plate 2639 ------- 03:09 42406 10.0 flat 03:11 42407 2.0 arc 03:36 42408 1200.0 target 03:59 42409 1201.0 target 04:26 42410 1502.0 target 04:54 42411 1502.0 target ----- sequence 42412, plate 2540 ------- 05:07 42412 10.0 flat 05:09 42413 2.0 arc 05:34 42414 1200.0 target 05:56 42415 1201.0 target 06:24 42416 1502.0 target 06:27 42417 10.0 flat 06:29 42418 2.0 arc ----- sequence 42419, plate 2670 ------- 06:44 42419 10.0 flat 06:47 42420 2.0 arc 07:11 42421 1200.0 target 07:33 42422 1201.0 target 08:01 42423 1503.0 target 08:29 42424 1500.0 target 08:51 42425 1202.0 target 08:55 42426 10.0 flat 08:57 42427 2.0 arc 09:30 42428 1501.0 target 10:02 42429 1802.0 target 10:35 42430 1800.0 target 11:08 42431 1800.0 target 11:11 42432 10.0 flat 11:13 42433 2.0 arc ----- sequence 42434, plate 2102 ------- 11:25 42434 10.0 flat 11:28 42435 2.0 arc 11:52 42436 1200.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:10Z 3 2634 26.23 0.0005 54.49 0.0028 201.79 -0.0006 1.000000 04:06Z 6 2639 -17.42 0.0002 56.02 0.0030 165.39 -0.0155 0.999900 05:18Z 2 2540 178.65 0.0038 39.18 0.0019 -9.58 -0.0421 0.999750 06:50Z 8 2670 114.26 0.0026 74.07 0.0042 -76.52 0.0054 1.000100 11:31Z 9 2102 109.07 0.0014 68.68 0.0041 -85.80 0.0083 1.000200 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:10Z 3 2634 1.00000 0 1292 125 26 54.5 5.7 7 188 gdr 1.3 04:06Z 6 2639 0.99990 988 2080 100 -17 56.0 5.3 8 203 gdr 1.2 05:18Z 2 2540 0.99975 2469 3338 75 179 39.2 4.3 2 203 gdr 1.4 06:49Z 8 2670 1.00010 -988 383 75 114 74.0 3.2 6 191 gdr 1.5 11:30Z 9 2102 1.00020 -1975 -451 50 109 68.6 3.7 9 266 gdr 1.8 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 20:44Z 42 14 10 198 (SSW) 679 - 21:16Z 41 14 8 190 (S) 693 - 21:47Z 41 15 12 196 (SSW) 611 - 22:19Z 39 10 1 151 (SSE) 605 - 22:49Z 40 12 6 196 (SSW) 632 - 23:19Z 37 14 8 197 (SSW) 596 - partly cloudy 00:14Z 36 7 9 158 (SSE) 560 - 00:46Z 41 4 7 211 (SSW) 745 - 01:19Z 41 0 7 180 (S) 664 - 01:49Z 40 1 10 181 (S) 697 - 02:19Z 39 2 9 180 (S) 593 - 02:50Z 40 1 7 181 (S) 569 - 03:20Z 40 0 10 201 (SSW) 625 - 03:51Z 40 1 8 191 (S) 814 - 04:21Z 40 0 10 215 (SW) 1079 - 04:51Z 41 0 7 181 (S) 1374 - 05:22Z 40 0 5 257 (WSW) 945 - 05:53Z 40 -3 9 227 (SW) 1701 - 06:27Z 38 -3 6 253 (WSW) 1367 - 06:57Z 38 -3 7 217 (SW) 1200 - 07:28Z 38 -5 8 215 (SW) 1298 - 07:58Z 35 1 7 198 (SSW) 1173 - 08:29Z 36 0 9 257 (WSW) 1335 - 08:59Z 35 3 12 252 (WSW) 1177 - 09:30Z 35 4 12 238 (WSW) 1155 - 10:01Z 37 5 6 261 (W) 1172 - 10:33Z 39 2 15 270 (W) 1105 - 11:04Z 39 -3 16 278 (W) 1231 - 11:35Z 38 2 13 270 (W) 1088 - 12:05Z 38 3 9 279 (W) 1106 - ---=== TELESCOPE STATUS ===--- 23:23Z Enclosure doors opened, fans and blowers on, louvers opened. 00:10Z Enclosure off Enclosure on, doors and louvers closed, fans off.
