APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday October 26, 2008 (MJD 54766) ---=== OBSERVING TEAM ===--- Dan Oravetz Kaike Pan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The night was lost to bad weather. We opened for 2.5 hours, but bad seeing prevent us collecting any good data. We did spectro monthly checkout tasks: bias, dark, and dithered flats. Fiducial read: Alt at 75 and Az at 107 only read out at one way. ---=== OBSERVING LOG ===--- Afternoon --------- During afternoon checkout, fiducials at 75 degree when up did not read out , but read when down. Az fiducial at 107 degree did not read out when going from 100-110, did read on the way back. The spectro focus was set for 11 C. 23:30Z start Night: ------ 01:25Z wind speed were over 40 mph, and dust is over 3K.Stop ventilation. Fans off, doors and louvers closed. 01:35Z: Spectro monthly checkout tasks: Cartridge 4, plate 3128. 01:36Z dithered flats.

So we decided to open. 09:45Z Because next possible plate, 3045 is not available yet, although cart 3, plate 3040 (pre-marvel) will expired in 30 min, we decided to try cart 3 first. Fk5 used for the field. Took 20 min to find the field, adjust focus. We don't have time to took data on this plate, so move to next plate 3045. 10:15Z cart 9, plate 3045 (marvel-pre). FK5 used for the field. The field is still very low, Alt at 29.8 degree. Seeing was so bad that we could not getfocus set. Human eyes could see images of guiding star, but guider could not make measurements on these images, and was not stable. 3.5 m has the same problem. Because of bad seeing, we was not able to getany good data. 11:40Z endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7763 22:56Z 23:15Z 100 O 88.91 93.70 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 55917, plate -9999 ------- 22:58 55917 0.0 bias 23:06 55918 0.0 bias ----- sequence 55919, plate 3128 ------- 23:17 55919 10.0 flat 23:19 55920 2.0 arc 23:23 55921 3.0 arc 23:25 55922 2.0 arc 23:43 55923 10.0 flat 23:45 55924 2.0 arc 01:41 55925 10.0 flat 01:45 55926 10.0 flat 01:49 55927 10.0 flat 01:53 55928 10.0 flat 01:58 55929 10.0 flat 02:02 55930 10.0 flat 02:06 55931 10.0 flat 02:10 55932 10.0 flat 02:15 55933 10.0 flat 02:19 55934 10.0 flat 02:23 55935 10.0 flat 02:28 55936 10.0 flat 02:32 55937 10.0 flat 02:36 55938 10.0 flat 02:40 55939 10.0 flat 02:45 55940 2.0 arc 02:47 55941 2.0 arc 02:51 55942 0.0 bias 02:53 55943 0.0 bias 02:56 55944 0.0 bias 02:58 55945 0.0 bias 03:00 55946 0.0 bias 03:02 55947 0.0 bias 03:05 55948 0.0 bias 03:07 55949 0.0 bias 03:09 55950 0.0 bias 03:11 55951 0.0 bias 03:14 55952 0.0 bias 03:16 55953 0.0 bias 03:18 55954 0.0 bias 03:20 55955 0.0 bias 03:23 55956 0.0 bias 03:25 55957 0.0 bias 03:27 55958 0.0 bias 03:29 55959 0.0 bias 03:32 55960 0.0 bias 03:34 55961 0.0 bias 03:36 55962 0.0 bias 03:39 55963 0.0 bias 03:41 55964 0.0 bias 03:43 55965 0.0 bias 03:45 55966 0.0 bias 04:24 55967 0.0 dark 04:46 55968 0.0 dark 05:04 55969 0.0 dark ---=== 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 22:57Z 51 29 31 72 (ENE) 2142 - clear 23:27Z 50 28 29 67 (ENE) 2219 - 23:58Z 48 28 27 60 (ENE) 2423 - 00:29Z 47 28 30 72 (ENE) 2470 - 00:59Z 46 28 18 68 (ENE) 2764 - 01:29Z 45 28 36 82 (E) 3130 - 02:00Z 43 27 37 74 (ENE) 3154 - 02:31Z 42 28 34 73 (ENE) 3373 - 03:02Z 40 27 34 64 (ENE) 3328 - 03:32Z 39 27 25 63 (ENE) 3359 - 04:02Z 39 26 24 71 (ENE) 3282 - 04:32Z 37 26 34 72 (ENE) 3229 - 05:02Z 36 25 33 74 (ENE) 3154 - 05:32Z 35 25 37 71 (ENE) 2751 - 06:05Z 34 24 28 81 (E) 2611 - 06:37Z 33 25 31 71 (ENE) 2533 - 07:09Z 34 24 27 81 (E) 2449 - 07:41Z 34 23 31 74 (ENE) 2262 - 08:14Z 35 23 23 80 (E) 1974 - 08:46Z 34 24 25 90 (E) 1960 - 09:18Z 33 24 24 87 (E) 1989 - 09:48Z 34 23 22 83 (E) 1914 - 10:19Z 36 22 19 86 (E) 1638 - 10:50Z 35 24 14 93 (E) 1690 - 11:21Z 35 26 19 83 (E) 1726 - clear ---=== TELESCOPE STATUS ===--- 23:30Z - Began ventilation.
