Subject: 2.5m obslog 20070508 (MJD 54229) Date: Wed, 9 May 2007 04:42:59 -0600 (MDT) From: doravetz@apo.nmsu.edu APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday May 8, 2007 (MJD 54229) ---=== OBSERVING TEAM ===--- Viktor Malanushenko (swing) Howard Brewington Dan Oravetz ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- High humidity, clouds, nearby radar returns and lightning (at the beginning of the night) throughout the night prevented us from getting on sky. Mounted the imager and took the monthly biases and flats (reduction results in Imaging Details section). We noticed that the imager bias vector for U3 looks a little different as compared to last month's. Also, the results for CCD76 as seen in the Imaging Details section under IMAGER BIAS looks atypical compared to the rest. During the imager mounting procedure we noticed the cart airsprings pressure was uncharacteristically low at ~10 psi and we adjusted it accordingly, increasing the pressure to 42 psi. Is there perhaps a leak? ---=== OBSERVING LOG ===--- Afternoon: --------- Rebooted 'astro ad1' - there were errors on server. Afternoon checkout went smoothly. No problems to report. Spectro focus has been adjusted for night temperature of 4C. Cartridge 8 is mounted. We did not begin ventilating on time due to high humidity (90%) and low dewpoint depression ( checkFlat 6808 31 . {42 WARN: leftGain } {42 FAIL: } Open /skycat/imager/54229/6808-31-u-flat.gif/gif Open /skycat/imager/54229/6808-31-g-flat.gif/gif Open /skycat/imager/54229/6808-31-r-flat.gif/gif Open /skycat/imager/54229/6808-31-i-flat.gif/gif Open /skycat/imager/54229/6808-31-z-flat.gif/gif 0 ---=== 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): yes QA Procedures Done (y/n): n/a UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 44727, plate -9999 ------- 22:21 44727 0.0 bias ----- sequence 44728, plate 2172 ------- 23:25 44728 10.0 flat 23:28 44729 2.0 arc 23:32 44730 3.0 arc 23:34 44731 3.0 arc 00:10 44732 10.0 flat 00:12 44733 2.0 arc ----- sequence 44734, plate -9999 ------- 00:23 44734 0.0 bias ----- sequence 44735, plate 2172 ------- 00:38 44735 0.0 bias ----- sequence 44736, plate -9999 ------- 02:29 44736 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 ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:44Z 41 37 11 84 (E) 324 - Partly cloudy 00:15Z 41 36 14 75 (ENE) 335 - Partly cloudy 00:45Z 38 35 10 80 (E) 394 - Partly cloudy 01:16Z 37 35 10 79 (E) 487 - Clouds 01:46Z 39 35 9 54 (NE) 793 - Clouds 02:18Z 37 36 9 70 (ENE) 496 - Clouds 02:49Z 36 36 13 61 (ENE) 506 - Clouds 03:21Z 36 36 10 72 (ENE) 409 - Partly cloudy 03:53Z 40 35 1 355 (NNW) 736 - Partly cloudy 04:26Z 41 35 4 318 (NW) 834 - Partly cloudy 04:58Z 39 35 2 338 (NNW) 566 - Partly cloudy 05:30Z 39 34 11 20 (NNE) 311 - Partly cloudy 06:02Z 38 33 20 34 (NE) 222 - Partly cloudy 06:34Z 42 29 1 286 (WNW) 305 - Partly cloudy 07:07Z 42 28 0 208 (SSW) 368 - Mostly cloudy 07:39Z 42 28 6 267 (W) 331 - Partly cloudy 08:11Z 40 29 1 254 (WSW) 343 - Mostly cloudy 08:43Z 41 29 2 128 (SE) 343 - Mostly cloudy 09:15Z 39 29 10 181 (S) 384 - Partly cloudy 09:47Z 40 30 8 180 (S) 387 - Partly cloudy 10:20Z 40 30 11 178 (S) 371 - Mostly cloudy ---=== TELESCOPE STATUS ===--- 06:40Z - Began ventilation.
