APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday February 28, 2003 (MJD 52699) ---=== OBSERVING TEAM ===--- Swing: Jurek Krzesinski Night: Mike Harvanek, Pete Newman Visitors: David Schlegel (PU, Christy Tremonti (JHU), Michael Blanton (NYU), Nikhil Padmanablan (PU), David Hogg (NYU) (where are you, Fink?) ---=== OBSERVING PLAN ===--- Science. ---=== OBSERVING SUMMARY ===--- Guess. ---=== OBSERVING LOG ===--- Spectrograph focus was checked and adjusted during the afternoon. See "Spectro Focus" section for details. Watcher reported an MCP:tpm error we have not seen before: ca (INVALID: 2003-03-01 01:39:51Z) Variable orographic clouds kept us closed from a little after sunset until ~03:45Z, when conditions seemed to stablise to partly cloudy but no risk of virga or heavier precipitation. We opened in the hope of doing spectroscopy. Observing sequence 03:54Z Plate 1210, cartridge 3. Guide stars on gotoField, which is good as we are still operating with a pointing model from the start of the last dark run. We have (S/N)^2 >= 7.7 on this plate from earlier observations. 04:25Z Before we finish the first calibration exposures, we are closed by clouds again. 06:10Z Snow. 10:30Z Give up, as we have a coating of wet snow on all surfaces and continued clouds. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3690 00:03Z 00:46Z 100 O -131.58 -120.70 87 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): n QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 19504, plate -9999 ------- 18:02Z 19504 0.0 bias {{}} Clear-down camera b2 after shutter through repair work 22:13Z 19544 0.0 bias {{}} 22:19Z 19545 10.0 flat test test 22:22Z 19546 2.0 arc test 22:25Z 19547 2.0 arc test ----- sequence 19548, plate 1210 ------- 22:37Z 19548 10.0 flat test 22:42Z 19549 10.0 flat test 22:47Z 19550 2.0 arc test 22:50Z 19551 2.0 arc test ----- sequence 19552, plate -9999 ------- 00:04 19552 0.0 bias ----- sequence 19553, plate 1210 ------- 00:09 19553 0.0 bias 00:13 19554 10.0 flat Spectro focus adjustments 00:17 19555 2.0 arc 00:21 19556 2.1 arc 00:24 19557 2.1 arc 00:34 19558 2.1 arc 00:37 19559 2.1 arc 01:06 19560 0.0 bias 01:15 19561 0.0 bias ----- sequence 19561, plate 1210 ------- 11.2 10.6 10.2 7.7 MJD 52677 04:09 19562 10.0 flat 04:12 19563 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:07Z 3 1210 98.25 0.0015 74.78 -0.0037 -91.78 0.0126 1.000150 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Nothing to ship ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 04:07Z 3 1210 1.00015 -1480 -102 0 98 74.7 -3.4 20 297 BG38 1.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:21Z 30 13 21 268 (W) 347 - Clear 23:54Z 30 15 23 274 (W) 391 - " 00:26Z 28 16 7 271 (W) 493 - Heavy patchy cloud 00:58Z 28 19 15 283 (WNW) 572 - " 01:30Z 27 19 15 278 (W) 629 - " 02:03Z 27 18 13 279 (W) 610 - " 02:35Z 26 16 11 280 (W) 527 - " 03:07Z 26 15 13 293 (WNW) 451 - " 03:39Z 25 15 8 301 (WNW) 506 - Patchy cloud 04:12Z 26 15 12 288 (WNW) 475 - " 04:45Z 26 14 12 301 (WNW) 368 - " 05:16Z 26 14 9 272 (W) 416 - " 05:48Z 26 14 12 282 (WNW) 401 - " 06:20Z 25 15 12 268 (W) 380 - Snow 06:53Z 26 16 18 278 (W) 344 - " 07:26Z 25 17 16 263 (W) 406 - " 07:57Z 24 17 14 272 (W) 374 - " 08:29Z 23 19 21 269 (W) 429 - " 09:02Z 22 20 18 274 (W) 388 - " 09:34Z 23 17 25 276 (W) 418 - Heavy cloud 10:06Z 23 16 14 301 (WNW) 433 - " 10:38Z 22 16 13 268 (W) 418 - " ---=== TELESCOPE STATUS ===--- 23:45Z Fans on 00:50Z Doors open 01:00Z Enclosure off 01:45Z Enclosure on - heavy orographic cloud! 03:45Z Enclosure off 04:05Z Enclosure on - MORE cloud.
