APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday November 27, 2006 (MJD 54067) ---=== OBSERVING TEAM ===--- Mike Harvanek Dan Long ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- An afternoon thundersnow dropped between 1 and 2 inches of sleet and snow shortly before sunset. One or more of the following weather maladies High humidity, clouds, and blowing snow, kept us closed all night. In the first part of the night while waiting on the weather, we took some dithered spectroscopic flats to take care of that task for shakeup (which is in a couple days). Snow removal on most sidewalks and around the 2.5m done. ---=== OBSERVING LOG ===--- 01:00Z Spectrograph focus checked, but not changed. Set for about 4 C. 02:15Z Started to run specFlats 15 on Cartridge 1, plate 2481 02:30Z specFlats 15 failed after two exposures. See problems section for details. 03:45Z Second attempt at specFlats 15 completed successfully. First flat of the successful sequence is 41589. 10:30Z The humidity begins to drop (split now between 2 and 3 C), but the wind speed does not (still 20 - 30 MPH). 11:10Z Even with the humidity toying with us, the combination of an above-freezing telescope (especially the primary) and blowing snow made us very wary. With only about an hour of night before twilight and no sign of calming winds, we decide to give up. 11:14Z endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6612 23:49Z 00:04Z 100 O 133.23 136.89 39 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):fwiw UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 41579, plate -9999 ------- 23:19 41579 0.0 bias 23:30 41580 0.0 bias ----- sequence 41581, plate 2481 ------- 00:08 41581 10.0 flat 00:11 41582 2.0 arc 00:21 41583 3.0 arc 00:23 41584 3.0 arc 02:15 41585 0.0 bias 02:19 41586 10.0 flat 02:23 41587 10.0 flat 02:27 41588 0.0 bias 02:44 41589 10.0 flat 02:48 41590 10.0 flat 02:52 41591 10.0 flat 02:56 41592 10.0 flat 03:00 41593 10.0 flat 03:04 41594 10.0 flat 03:08 41595 10.0 flat 03:12 41596 10.0 flat 03:16 41597 10.0 flat 03:20 41598 10.0 flat 03:24 41599 10.0 flat 03:28 41600 10.0 flat 03:31 41601 10.0 flat 03:35 41602 10.0 flat 03:39 41603 10.0 flat 03:43 41604 2.0 arc 03:45 41605 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:15Z 34 30 24 228 (SW) 665 - Cloudy 22:47Z 32 32 18 259 (W) 11779 - Fog, Snow 23:18Z 32 32 29 258 (WSW) 9303 - Fog, Sleet, Thunder 23:48Z 30 30 23 265 (W) 3857 - Fog, Snow 00:18Z 30 30 19 268 (W) 5164 - Fog, Snow 00:49Z 30 30 21 255 (WSW) 248 - Fog 01:20Z 30 30 19 256 (WSW) 266 - Fog 01:51Z 30 30 16 262 (W) 7390 - Fog 02:22Z 31 30 23 243 (WSW) 435 - Mostly Cloudy 02:54Z 30 30 22 262 (W) 381 - Cloudy 03:25Z 30 29 23 255 (WSW) 410 - Partly Cloudy 03:56Z 29 28 27 255 (WSW) 469 - MClr, Blowing Snow 04:28Z 29 28 28 269 (W) 514 - PC, Blowing Snow 04:58Z 29 28 24 266 (W) 491 - PC, Blowing Snow 05:29Z 29 28 23 259 (W) 505 - PC, Blowing Snow 05:59Z 29 28 26 265 (W) 583 - MC, Blowing Snow 06:30Z 28 27 23 257 (WSW) 604 - MClr, Blowing Snow 07:00Z 28 27 21 269 (W) 658 - MClr, Blowing Snow 07:30Z 27 25 21 266 (W) 730 - MClr, Blowing Snow 08:03Z 28 24 23 266 (W) 814 - MClr, Blowing Snow 08:33Z 27 26 16 272 (W) 866 - PC, Blowing Snow 09:03Z 27 25 23 263 (W) 885 - MClr, Blowing Snow 09:34Z 26 24 22 250 (WSW) 874 - Clr, Blowing Snow 10:04Z 26 24 21 244 (WSW) 887 - Clr, Blowing Snow 10:36Z 27 22 28 239 (WSW) 701 - Clr, Blowing Snow 11:08Z 28 20 20 260 (W) 612 - Clr, Blowing Snow ---=== TELESCOPE STATUS ===--- 11:10Z Enclosure never opened.
