APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday March 7, 2009 (MJD 54898) ---=== OBSERVING TEAM ===--- Elena Malanushenko Dmitry Bizyaev Nathan De Lee (Marvels) ---=== OBSERVING PLAN ===--- Marvels Science ---=== OBSERVING SUMMARY ===--- Big part of the night was lost due to clouds and hight dust counts. Got signal on Marvels plates: 3219B (c 7) 3277 A & B (c 5) 3280A (c 4) ---=== OBSERVING LOG ===--- Afternoon: ----------- All systems were checked and working properly. Spectro foccus set for 8 C and we did not adjust it. ntp_check ok spectro bias ok Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00059620.fit -6.1 -4.2 -2.9 2.3 7.6 9.0 10.1 sdR-b2-00059620.fit -7.7 -6.5 -4.0 1.1 7.1 8.6 10.7 sdR-r1-00059620.fit -6.8 -5.8 -3.8 1.2 6.2 8.4 10.2 sdR-r2-00059620.fit -8.1 -6.4 -4.9 1.0 6.2 7.7 9.8 Night: ------- Evening: overcasted sky, wind is yellow to red 00:29Z ventilation started 01:40Z we opened enclosure. spectro dewar replaced.

We don't see fk5 star, or see it barely with 20 sec guider exposure. 03:27Z dome closed because dust count jumped over 5000 and continue to rise. We closed because clouds prevent observations any way. 04:15Z dust count went down, we started ventilation. Clouds everywhere, any way. 04:45Z ventilation stopped again: dust count jumped over 5000. 06:03Z ventilation started, dome opened. 06:05Z cart. 1 is prepared MS calibrations 06:10Z cart. 7 plate 3219 is mounted, f.

Oups, a lot of clouds. We cannot observe this plate anymore, twilight passed by 10 min, and eevn more clouds are coming. 12:18Z dome closed 12:23Z endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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 59619, plate -9999 ------- 23:53 59619 0.0 bias 23:57 59620 0.0 bias ----- sequence 59621, plate 3231 ------- 00:03 59621 10.0 flat 00:05 59622 2.0 arc 00:09 59623 2.0 arc 00:11 59624 3.0 arc 02:26 59625 10.0 flat 02:28 59626 2.0 arc ----- sequence 59627, plate 3340 ------- 11:58 59627 10.0 flat 12:01 59628 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 06:23Z 7 3219 205.79 0.0038 55.03 0.0013 49.86 0.0084 1.000050 08:29Z 4 3280 296.01 0.0038 53.62 0.0013 129.28 0.0084 0.999920 09:31Z 4 3280 243.46 0.0018 51.51 -0.0006 93.31 0.0084 0.999900 10:39Z 5 3277 267.10 0.0018 51.04 -0.0006 110.09 0.0084 0.999880 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 06:23Z 7 3219 1.00005 -493 957 200 206 55.0 1.8 11 260 -- 2.0" 08:29Z 4 3280 0.99992 789 1983 160 296 53.6 1.6 16 268 -- 1.8" 09:31Z 4 3280 0.99990 986 2153 160 243 51.5 1.0 20 264 -- 2.0" 10:39Z 5 3277 0.99988 1184 2278 120 267 51.1 0.6 13 274 -- 1.6" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:51Z 40 12 29 264 (W) 476 - 00:51Z 39 9 27 261 (W) 725 - clouds 01:21Z 38 7 19 265 (W) 539 - '' 01:51Z 38 4 27 245 (WSW) 637 - '' 02:24Z 38 2 27 282 (WNW) 656 - clouds w/small ptchs 02:56Z 36 1 22 292 (WNW) 2601 - '' 03:28Z 35 2 19 286 (WNW) 2649 - '' 04:00Z 35 1 10 269 (W) 2501 - '' 04:32Z 35 0 20 272 (W) 4728 - '' 05:04Z 35 -1 7 264 (W) 3545 - '' 05:36Z 35 -1 14 305 (NW) 2157 - '' 06:06Z 35 -1 13 273 (W) 986 - mostly clear 06:37Z 35 -4 11 272 (W) 457 - clear 07:08Z 35 -1 13 255 (WSW) 613 - '' 07:41Z 34 0 15 262 (W) 414 - '' 08:13Z 35 0 13 264 (W) 427 - '' 08:44Z 34 1 15 263 (W) 415 - '' 09:16Z 34 0 13 264 (W) 351 - '' 09:49Z 34 1 7 262 (W) 338 - '' 10:22Z 33 1 16 272 (W) 347 - '' 10:54Z 33 1 10 263 (W) 341 - '' 11:26Z 33 2 7 282 (WNW) 352 - some clouds 11:58Z 33 2 12 274 (W) 343 - clouds ---=== TELESCOPE STATUS ===--- 00:29Z - Began ventilation.
