APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday February 11, 2007 (MJD 54143) ---=== OBSERVING TEAM ===--- Howard Brewington Steph Snedden ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds, high humidity and rain/snow prevented data taking. This month's spectro dithered flats were done. A spectro autofill was forced and topped off at the end of the night. The imager dewar was replaced with a full one. Engineering crew please note that the threaded sleeve on the imager LN2 fill line has been abused and the edges worn down so that the wrench no longer fits and the sleeve is hard to tighten down. ---=== OBSERVING LOG ===--- Afternoon: ---------- No new problems with afternoon checkout. The 45 deg alt fiducial only read going down. The "90 deg" fiducial did not read at all, as usual. Spectro focus was checked but not adjusted. Night: ------ Overcast skies with radar return nearby kept us closed, although we ventilated until the humidity rose. 02:59Z - Rain. We did the monthly dithered flats during this time. The relevant frame numbers are: Dithered flats: 42895 - 42909 arcs: 42910, 42911 All collimator actuators moved properly and returned to the initial positions at the end without problems. 03:15Z - Thunder & lightning for about a half hour. For the rest of the night, we had high humidity and clouds/fog with scattered rain/snow showers. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6715 22:45Z 23:12Z 100 O -167.91 -161.27 46 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):n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 42890, plate 1845 ------- 23:06 42890 10.0 flat 23:08 42891 2.0 arc collimation check 23:13 42892 3.0 arc " 23:15 42893 3.0 arc " ----- sequence 42894, plate -9999 ------- 23:23 42894 0.0 bias ----- sequence 42894, plate 1845 ------- 02:34 42895 10.0 flat Dithered flats 02:37 42896 10.0 flat " 02:41 42897 10.0 flat " 02:45 42898 10.0 flat " 02:50 42899 10.0 flat " 02:54 42900 10.0 flat " 02:58 42901 10.0 flat " 03:02 42902 10.0 flat " 03:06 42903 10.0 flat " 03:10 42904 10.0 flat " 03:14 42905 10.0 flat " 03:17 42906 10.0 flat " 03:21 42907 10.0 flat " 03:25 42908 10.0 flat " 03:30 42909 10.0 flat " 03:34 42910 2.0 arc arc for dithered flats 03:37 42911 2.0 arc " ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== 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 23:03Z 41 27 -9999 -9999 (N) 512 - cloudy 23:34Z 40 27 -9999 -9999 (N) 588 - ' 00:05Z 40 27 -9999 -9999 (N) 528 - ' 00:35Z 39 28 -9999 -9999 (N) 584 - ' 01:05Z 39 28 -9999 -9999 (N) 750 - ' 01:35Z 38 28 -9999 -9999 (N) 589 - ' 02:06Z 38 31 -9999 -9999 (N) 573 - ' 02:36Z 37 31 -9999 -9999 (N) 576 - ' 03:08Z 37 32 -9999 -9999 (N) 614 - ' 03:40Z 36 32 -9999 -9999 (N) 595 - ' 04:12Z 35 32 -9999 -9999 (N) 639 - ' 04:44Z 35 31 -9999 -9999 (N) 562 - ' 05:16Z 34 31 -9999 -9999 (N) 583 - ' 05:49Z 33 31 -9999 -9999 (N) 548 - ' 06:21Z 33 31 -9999 -9999 (N) 517 - ' 06:53Z 33 32 -9999 -9999 (N) 498 - ' 07:25Z 32 31 -9999 -9999 (N) 482 - ' 07:57Z 31 31 -9999 -9999 (N) 585 - ' 08:27Z 31 31 -9999 -9999 (N) 469 - ' 08:57Z 31 31 -9999 -9999 (N) 490 - ' 09:28Z 30 30 -9999 -9999 (N) 408 - ' 10:00Z 30 30 -9999 -9999 (N) 72157 - ' 10:32Z 29 30 -9999 -9999 (N) 136422 - ' 11:04Z 29 29 -9999 -9999 (N) 2344 - ' 11:38Z 27 27 -9999 -9999 (N) 2540 - ' ---=== TELESCOPE STATUS ===--- 00:45 - Opened doors partway and started ventilation. 02:06Z - Closed doors, shut off ventilation. 11:35Z - swapped out imager dewar.
