APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday January 6, 2008 (MJD 54472) ---=== OBSERVING TEAM ===--- Viktor Malanushenko (days) Howard Brewington (observer) Kaike Pan (observer) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The night was lost to clouds and/or high humidity. The computer monitor for photo-one started smoking and stopped working. As we closed for the night, we noticed the imager's psi was only at 15.4; we thought it was because the imager just filled. However, we heard but could not find an air leak in the rot_rack at the southwest corner of the lower enclosure where the small tank of GN2 is mounted. Yet, the leak detector was not indicating a leak. We adjusted the valve to increase the pressure to about 16psi but noticed that the pressure began to fall very slowly. According to the imager plot, in fact, the pressure had been decreasing for the last 14 hours but never went below 15psi. ---=== OBSERVING LOG ===--- Afternoon: ---------- All equipment are checked and work properly. Spectro collimation set for 0C - +1C. Ventilation is started at 23:16Z. Cart 6 is mounted. Night: ------ 00:09Z Sunset; we had very thick clouds and high winds. So, we waited for better conditions. 01:37Z Evening twilight 02:15Z Doors and louvers closed, fans off as humidity increased to more than 80%. 06:30Z Humidity = 100% 10:10Z The computer monitor for photo-one started smoking and stopped working. We turned the monitor off. 11:50Z endNight finished; misc Watcher messages are posted in the Problems Section 12:43Z Morning Twilight ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7272 21:49Z 22:18Z 100 O 142.24 149.52 62 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 48679, plate -9999 ------- 21:47 48679 0.0 bias ----- sequence 48680, plate 2608 ------- 21:57 48680 10.0 flat 22:00 48681 2.0 arc 22:18 48682 3.0 arc 22:20 48683 3.0 arc 23:23 48684 0.0 bias ----- sequence 48685, plate -9999 ------- 07:59 48685 0.0 bias ---=== 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 ------------------------------------------------------------------------------ 08:03Z 6 2608 1.00000 0 1257 0 121 30.0 -0.6 16 259 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 20:58Z 36 27 29 252 (WSW) 463 - 21:30Z 36 27 25 252 (WSW) 679 - 22:02Z 36 27 23 222 (SW) 719 - 22:33Z 36 27 22 253 (WSW) 584 - 23:06Z 36 27 23 238 (WSW) 531 - 23:37Z 36 28 26 258 (WSW) 600 - 00:09Z 36 28 26 253 (WSW) 1820 - 00:41Z 35 27 31 249 (WSW) 1675 - 01:14Z 35 27 23 258 (WSW) 2013 - 01:46Z 34 28 24 264 (W) 1400 - 02:18Z 34 29 19 269 (W) 670 - 02:50Z 33 30 23 285 (WNW) 691 - 03:23Z 33 31 19 262 (W) 538 - 03:55Z 33 29 28 259 (W) 462 - 04:27Z 32 29 33 236 (SW) 420 - 04:59Z 31 30 19 259 (W) 451 - 05:31Z 31 30 24 255 (WSW) 784 - 06:04Z 31 31 27 264 (W) 315 - 06:36Z 31 31 24 254 (WSW) 1113 - 07:08Z 31 31 24 249 (WSW) 732 - 07:40Z 31 31 23 266 (W) 805 - 08:11Z 30 31 25 251 (WSW) 1278 - 08:41Z 30 31 24 248 (WSW) 1389 - 09:11Z 30 30 28 258 (WSW) 1066 - 09:44Z 30 30 27 260 (W) 1022 - 10:16Z 29 30 21 256 (WSW) 3834 - 10:48Z 29 30 22 260 (W) 2923 - 11:20Z 29 29 25 245 (WSW) 11787 - 11:52Z 29 29 25 226 (SW) 11293 - ---=== TELESCOPE STATUS ===--- 23:16Z - Began ventilation.
