APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday February 13, 2008 (MJD 54510) ---=== OBSERVING TEAM ===--- Steph Snedden Kaike Pan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- First 7.5 hours was lost to clouds. We finished one cloud night task: spectro dithered flats. Fished two chunk plates: 2150 and 2770. ---=== OBSERVING LOG ===--- Afternoon: ---------- We started having site-wide (all of Sunspot, actually) power flucuations at about 21:30Z. We delayed moving the telescope until we were back on site power, just to be on the safe side, and we had the time to spare. We came back on line power at 00:30Z when the line at mile marker 6 was repaired, and we completed the telescope checkout without incident. The only altitude fiducial readout is at 75 degree. Started ventilation at 00:15Z. Night: ------ 00:50Z it was cloudy but no nearby radar return, we decided to open. 08:40Z dithered flats. Frames from 50011-50025. The associated arc frames are 50026 and 50027. 09:20Z it started to clear up, mounted cartridge 8. 09:30Z cart 8, plate 2150 (chunk). FK5 used. 09:40Z 1500 s exposure. The plate was DONE with signals from previous nights. 10:10Z cart 7, plate 2770 (chunk). SOGTF. The plate was DONE with four exposures at a total time of 4500s. 12:35Z endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7323 23:12Z 23:35Z 100 O -159.37 -153.54 38 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): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 50002, plate -9999 ------- 22:54 50002 0.0 bias ----- sequence 50003, plate 2942 ------- 23:13 50003 10.0 flat 23:16 50004 2.0 arc 23:31 50005 2.0 arc 23:33 50006 3.0 arc ----- sequence 50007, plate -9999 ------- 00:42 50007 0.0 bias ----- sequence 50008, plate -9999 ------- 02:53 50008 0.0 bias ----- sequence 50009, plate 2942 ------- 07:24 50009 10.0 flat 07:26 50010 2.0 arc 07:44 50011 10.0 flat 07:48 50012 10.0 flat 07:53 50013 10.0 flat 07:57 50014 10.0 flat 08:01 50015 10.0 flat 08:05 50016 10.0 flat 08:09 50017 10.0 flat 08:13 50018 10.0 flat 08:18 50019 10.0 flat 08:22 50020 10.0 flat 08:26 50021 10.0 flat 08:30 50022 10.0 flat 08:34 50023 10.0 flat 08:39 50024 10.0 flat 08:43 50025 10.0 flat 08:47 50026 2.0 arc 08:50 50027 2.0 arc ----- sequence 50028, plate 2150 ------- 5.9 4.2 5.5 4.6 09:32 50028 10.0 flat 09:35 50029 2.0 arc 10:07 50030 1501.0 target ----- sequence 50031, plate 2770 ------- 36.5 23.9 34.3 28.7 10:20 50031 10.0 flat 10:23 50032 2.0 arc 10:49 50033 1201.0 target 11:12 50034 1201.0 target 11:35 50035 1200.0 target 11:53 50036 900.0 target 11:56 50037 10.0 flat 11:58 50038 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 09:41Z 8 2150 84.58 0.0018 51.08 0.0005 244.29 0.0166 1.000160 10:33Z 7 2770 47.60 -0.0020 73.04 0.0010 221.51 0.0246 1.000060 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 23:05Z 9 2942 0.99993 691 1909 55 121 30.0 6.9 20 225 09:41Z 8 2150 1.00016 -1580 -55 75 85 51.1 2.4 25 249 -- 2.1 10:33Z 7 2770 1.00006 -593 711 75 48 73.1 2.0 23 232 -- 1.6 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:52Z 44 14 15 227 (SW) 1303 - overcast 23:23Z 43 14 13 246 (WSW) 1153 - 23:53Z 40 13 17 240 (WSW) 1311 - 00:27Z 38 13 14 215 (SW) 1193 - 01:03Z 38 12 16 204 (SSW) 855 - 01:35Z 39 11 22 223 (SW) 746 - 02:07Z 39 11 18 204 (SSW) 531 - 02:40Z 41 11 22 215 (SW) 450 - 03:13Z 40 12 21 210 (SSW) 487 - 03:44Z 40 13 24 212 (SSW) 657 - 04:16Z 40 13 20 203 (SSW) 722 - 04:48Z 40 12 18 219 (SW) 645 - 05:20Z 39 12 15 195 (SSW) 724 - 05:50Z 39 12 23 221 (SW) 695 - 06:21Z 38 12 23 215 (SW) 806 - 06:51Z 37 13 20 214 (SW) 905 - 07:21Z 37 14 22 210 (SSW) 1059 - 07:53Z 36 15 22 223 (SW) 1106 - 08:25Z 37 14 14 184 (S) 1433 - 08:57Z 36 13 23 235 (SW) 1201 - overcast 09:29Z 36 9 25 244 (WSW) 1164 - mostly clear 10:00Z 35 8 13 255 (WSW) 827 - 10:32Z 35 9 16 236 (SW) 1517 - clear 11:03Z 34 9 20 255 (WSW) 1149 - 11:35Z 34 8 22 272 (W) 912 - 12:06Z 34 8 27 269 (W) 699 - clear 12:38Z 33 8 31 267 (W) 723 - ---=== TELESCOPE STATUS ===--- 00:15Z - Began ventilation.
