APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday May 3, 2008 (MJD 54590) ---=== OBSERVING TEAM ===--- Night: Shannon Watters, Howard Brewington Swing: Kaike Pan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds and dust were a problem for most of the night. Integrated dust count was about 40K. Completed plates: 2931 2971 ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems checked, and woorking properly. The spectro focus ws set for 7.5 C. Cartridge 6 was mounted for the begining of the night. No evening ventilation due to hight dust count (3.5K) Night: ------- 01:30Z Doors/louvers opened and fans on, but was late because of high dust. 01:44Z Sunset; enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, checked fiducial crossings for each axis, started the DIMM. 02:10Z Cart 06, 2931 (segFaint); an fk5 was used to find the field in bright twilight and thin clouds. Seeing was ~1.0" as reported by the DIMM. 02:56 52524 10.0 flat 02:59 52525 2.0 arc 03:17 Evening twilight ended 03:25 52526 1200.0 target 03:57 52527 1801.0 target 04:30 52528 1801.0 target 04:34 52529 10.0 flat 04:36 52530 2.0 arc 05:10 52531 1801.0 target 05:33 52532 1202.0 target 05:36 52533 10.0 flat 05:39 52534 2.0 arc Cart 06 was declared DONE; see below: MJD b1 r1 b2 b1 ---------------------------- 54589 41.3 33.2 44.3 25.9 54590 48.8 32.8 52.6 25.7 ---------------------------- Total 51.6 05:45Z Cart 02, plate 2971 (chunk192).

Dust was ~5K. We waited for better conditions but did not start imager cals since there was a chance to return to the sky. Unfortunately, conditions did not improve. 10:19Z endNight finished and was happy 10:46Z Morning twilight ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7479 23:52Z 00:14Z 100 O -70.45 -64.96 51 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 52514, plate -9999 ------- 23:55 52514 0.0 bias ----- sequence 52515, plate 2931 ------- 00:02 52515 10.0 flat 00:05 52516 2.0 arc 00:12 52517 3.0 arc 00:15 52518 2.0 arc 00:35 52519 10.0 flat 00:37 52520 2.0 arc 00:44 52521 3.0 arc 00:46 52522 3.0 arc 02:56 52524 10.0 flat 02:59 52525 2.0 arc 03:25 52526 1200.0 target 03:57 52527 1801.0 target 04:30 52528 1801.0 target 04:34 52529 10.0 flat 04:36 52530 2.0 arc 05:10 52531 1801.0 target 05:33 52532 1202.0 target 05:36 52533 10.0 flat 05:39 52534 2.0 arc ----- sequence 52535, plate 2971 ------- 05:56 52535 10.0 flat 05:59 52536 2.0 arc 06:26 52537 1200.0 target ----- sequence 52538, plate 2973 ------- 06:39 52538 10.0 flat 06:42 52539 2.0 arc 07:16 52540 1802.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:03Z 6 2931 109.83 0.0005 48.80 0.0036 -100.27 0.0032 1.000270 05:55Z 2 2971 110.83 0.0014 48.49 0.0053 -99.85 0.0205 1.000190 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 03:03Z 6 2931 1.00027 -2666 -971 50 110 48.7 7.7 8 223 gdr 1.3 05:54Z 2 2971 1.00019 -1876 -416 -50 111 48.3 8.5 10 235 gdr 1.6 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:33Z 49 8 8 226 (SW) 3043 - 23:05Z 54 10 9 198 (SSW) 2934 - 23:35Z 54 11 14 208 (SSW) 2769 - 00:06Z 54 11 11 180 (S) 3157 - 00:36Z 53 11 10 231 (SW) 3259 - 01:07Z 49 11 12 209 (SSW) 3054 - 01:55Z 45 11 9 198 (SSW) 3241 - 02:25Z 45 11 9 221 (SW) 3405 - 02:58Z 46 11 10 193 (SSW) 3616 - 03:28Z 46 11 10 211 (SSW) 3809 - 03:59Z 47 9 11 248 (WSW) 3796 - 04:31Z 48 8 13 273 (W) 3487 - 05:01Z 48 5 11 267 (W) 3313 - 05:32Z 47 6 9 259 (W) 3601 - 06:02Z 47 8 11 229 (SW) 3666 - 06:32Z 46 9 11 215 (SW) 3987 - 07:02Z 46 9 8 196 (SSW) 4390 - 07:33Z 46 8 7 189 (S) 4763 - 08:03Z 46 8 10 192 (SSW) 4726 - 08:34Z 45 8 12 190 (S) 4535 - 09:05Z 47 8 12 179 (S) 4939 - 09:35Z 45 10 10 177 (S) 5482 - 10:08Z 45 10 9 179 (S) 5814 - ---=== TELESCOPE STATUS ===--- 01:30Z Opened louvers, cracked doors, turned on fans. 01:44Z Enclosure off. 07:40Z Enclosure on, doors closed, fans and blowers off, louvers closed.
