APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday February 10, 2007 (MJD 54142) ---=== OBSERVING TEAM ===--- Howard Brewington Shannon Watters ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds were a problem at the start and then again at the end of the night. Yet, we captured signal on two plates (2667 and 2707). ---=== OBSERVING LOG ===--- Afternoon: ------------- No Problems to report. Spectro focus was checked but not adjusted; numbers are posted in the Problems Section. Night: ------------- 12:45Z We opened at sunset and hoped to get one spectro exposure before the storm to the northwest became a problem. Unfortunately, the rain got too close for comfort, and we had to close at 01:35Z. 04:00Z Enclosure off again 04:17Z Cart 06, plate 2548 (segFaint). Although we found a faint fk5, we were unable to locate guide stars. And, the plate expired before we could obtain any signal. 04:42Z Cart 03, plate 2667 (segue158). An Fk5 was used to find the field Completed eight exposures; however, most were declared bad by SOS. We sent an email to Brain Yanny to check the signal total. 09:01Z Cart 05, plate 2707 (segFaint). Completed five exposures but could not declare this plate done. 12:06Z Cart 07, plate 1845 (chunk95). We move to this plate, which was at a much higher alt, because of thin clouds. Unfortunately, the clouds became a greater problem. 12:35Z We closed We went home. Misc Watcher messages are posted in the Problems Section. endNight finished and was happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6714 22:33Z 00:34Z 100 O -172.02 -141.52 59 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 42862, plate -9999 ------- 22:35 42862 0.0 bias ----- sequence 42863, plate 1845 ------- 23:06 42863 10.0 flat 23:09 42864 2.0 arc 00:28 42865 0.0 bias 00:31 42866 2.0 arc 00:33 42867 3.0 arc ----- sequence 42868, plate 2667 ------- 04:50 42868 10.0 flat 04:52 42869 2.0 arc 05:18 42870 1200.0 target 05:46 42871 1502.0 target 06:13 42872 1501.0 target 06:46 42873 1801.0 target 06:52 42874 10.0 flat 06:55 42875 2.0 arc 07:27 42876 1800.0 target 07:57 42877 1564.0 target 08:20 42878 1201.0 target 08:52 42879 1800.0 target ----- sequence 42880, plate 2707 ------- 09:04 42880 10.0 flat 09:07 42881 2.0 arc 09:31 42882 1200.0 target 09:53 42883 1200.0 target 10:21 42884 1500.0 target 10:49 42885 1500.0 target 11:16 42886 1501.0 target 11:48 42887 1341.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:58Z 3 2667 49.59 -0.0016 59.45 0.0009 220.67 0.0055 1.000190 09:15Z 5 2707 24.83 -0.0020 46.22 -0.0004 200.81 -0.0158 1.000080 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 00:00Z 7 0 1.00000 0 1257 0 121 30.0 5.6 -9999 -9999 04:57Z 3 2667 1.00019 -1876 -324 75 50 59.3 4.6 -9999 -9999 gd 1.2 09:15Z 5 2707 1.00008 -790 565 25 25 46.2 4.3 -9999 -9999 gd 1.2 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:34Z 44 22 -9999 -9999 (N) 173 - 23:04Z 44 22 -9999 -9999 (N) 173 - 23:34Z 44 23 -9999 -9999 (N) 137 - 00:05Z 41 24 -9999 -9999 (N) 236 - 00:36Z 39 24 -9999 -9999 (N) 252 - 01:06Z 39 23 -9999 -9999 (N) 221 - 01:37Z 40 22 -9999 -9999 (N) 179 - 02:07Z 40 23 -9999 -9999 (N) 194 - 02:39Z 41 24 -9999 -9999 (N) 328 - 03:09Z 41 24 -9999 -9999 (N) 303 - 03:39Z 41 24 -9999 -9999 (N) 279 - 04:09Z 40 24 -9999 -9999 (N) 306 - 04:40Z 40 25 -9999 -9999 (N) 458 - 05:10Z 40 25 -9999 -9999 (N) 411 - 05:40Z 41 24 -9999 -9999 (N) 447 - 06:10Z 40 24 -9999 -9999 (N) 399 - 06:40Z 40 23 -9999 -9999 (N) 378 - 07:10Z 39 22 -9999 -9999 (N) 348 - 07:41Z 39 24 -9999 -9999 (N) 308 - 08:11Z 40 24 -9999 -9999 (N) 269 - 08:41Z 40 23 -9999 -9999 (N) 264 - 09:11Z 40 22 -9999 -9999 (N) 220 - 09:42Z 40 23 -9999 -9999 (N) 307 - 10:13Z 40 22 -9999 -9999 (N) 279 - 10:43Z 40 22 -9999 -9999 (N) 283 - 11:14Z 40 23 -9999 -9999 (N) 343 - 11:46Z 39 22 -9999 -9999 (N) 328 - 12:18Z 38 23 -9999 -9999 (N) 343 - ---=== TELESCOPE STATUS ===--- 00:40Z Doors and louvers opened, fans on 12:45Z Enclosure off 01:35Z Enlosure on 04:00Z Enclosure off 12:35ZDoors and louvers closed, fans off No interlocks bypassed.
