APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday June 29, 2009 (MJD 55012) ---=== OBSERVING TEAM ===--- Howard Brewington Dmitry Bizyaev ---=== OBSERVING PLAN ===--- SEGUE2 Science! ---=== OBSERVING SUMMARY ===--- The night was completely lost due to clouds and rain. No Marvels calibrations were done (according to Nathan and Frank's request). ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:00Z Restarted the servers 23:15Z Could not access SOS web page. Jon B. found that the media converter had failed. Thanks Jon! 23:44Z Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 119G 16G 89% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 776G 95G 90% /data sdssfiles1p:/data1/data 1.5T 595G 798G 43% /files 23:48Z Completed the apo_plotbias; results posted in Prob Section 23:50Z Spectro focus was checked but not adjusted. It's set for about 14-degree C, and the collimate numbers are posted in the Problem Section. 02:15Z Sunset Night: ------ Sunset: cloudy, danger of rain. We tried to prepare for the rest of Marvels calibrations, but Frank Varosi and Nathan did not recommend to do cals tonight, because the instrument might not be stable yet, as a result of yesterday's problems. 07:22Z We are surrounded by clouds with lightnings but the sky is mostly clear and humidity has dropped down to a decent level. We satrted ventilation. 08:55Z humidity spikes again, we stopped ventilation. Rain danger again, cloud camera closed. 09:55Z 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 62000, plate 3478 ------- 23:44 62000 0.0 bias 23:52 62001 10.0 flat 23:55 62002 2.0 arc 00:00 62003 2.0 arc 00:03 62004 3.0 arc ----- sequence 62005, plate -9999 ------- 00:14 62005 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 23:38Z 66 50 5 266 (W) 330 - 00:09Z 64 48 1 305 (NW) 449 - 01:45Z 60 49 7 114 (ESE) 544 - cloudy 02:17Z 59 49 8 113 (ESE) 574 - '' 02:48Z 58 50 13 131 (SE) 550 - '' 03:22Z 57 50 9 128 (SE) 716 - '' 03:52Z 58 50 13 152 (SSE) 715 - '' 04:22Z 58 49 10 150 (SSE) 842 - '' 04:54Z 54 50 18 60 (ENE) 666 - '' 05:25Z 53 49 10 128 (SE) 511 - '' 05:59Z 52 48 13 78 (ENE) 849 - '' 06:31Z 55 43 12 64 (ENE) 593 - '' 07:03Z 57 42 1 216 (SW) 362 - '' 07:35Z 54 47 5 192 (SSW) 495 - '' 08:05Z 57 48 6 212 (SSW) 656 - '' 08:36Z 56 48 5 248 (WSW) 642 - '' 09:06Z 54 48 7 195 (SSW) 609 - '' 09:40Z 56 44 4 264 (W) 427 - ---=== TELESCOPE STATUS ===--- 07:22Z Doors and louvers opened, fans on. 08:55Z Ventilation stopped, doors closed.
