APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday August 29, 2008 (MJD 54708) ---=== OBSERVING TEAM ===--- Howard Brewington Dan Oravetz Paul Harding ---=== OBSERVING PLAN ===--- M1 collimation ---=== OBSERVING SUMMARY ===--- The night was lost to high winds, high humidity, rain, and clouds. Howard had a problem with his x11 session (see log). ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working properly. Spectro focus still set for ~12C. Collimate numbers are found in the Problems section. During the fiducials check at the telescope, the rotator aborted once. We slewed from 121,90,30 to 121,90,00 and the rotator stopped at about 6.5 degrees. We tried again, slewing from 121,90,6.5 where things stopped, back to 121,90,30 and then back to 121,90,00 and everything worked normally. sdsshost2.apo.nmsu.edu % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 112G 24G 83% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 646G 225G 75% /data sdssfiles1:/data1/data 1.5T 595G 798G 43% /files High winds, high humidity and clouds. Night: ----- 04:12Z - Howard opened an xterm and a Mozilla from that xterm. After exiting the Mozilla, he killed the xterm with `exit' and then ALL of his xterms and the associated processes died...he lost everything. Each of his xterms were opened independently. He experimented again by opening two independent xterms, issued `exit' in one of them, and both xterms subsequently disappeared. Paul showed us the new guider, the guider layout, and the cabling, and talked to us about guider functionality in general. 10:04Z - 103.4% humidity and still raining. We called it a night. 10:09Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7661 22:15Z 23:25Z 100 O 21.39 39.08 129 ignore 7662 04:41Z 09:06Z 100 O 118.14 -175.34 47 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 54430, plate 3106 ------- 22:40 54430 0.0 bias 23:09 54431 10.0 flat 23:11 54432 2.0 arc 23:14 54433 3.0 arc 23:17 54434 3.0 arc ----- sequence 54435, plate -9999 ------- 23:38 54435 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 22:38Z 53 51 18 78 (ENE) 697 - clouds 23:30Z 53 50 18 80 (E) -9999 - clouds 00:02Z 53 50 23 79 (E) -9999 - clouds 00:34Z 53 49 28 76 (ENE) -9999 - clouds 01:06Z 52 49 19 89 (E) -9999 - clouds 01:39Z 51 49 19 96 (E) -9999 - clouds 02:11Z 50 48 33 88 (E) -9999 - clouds 02:43Z 49 48 30 81 (E) -9999 - clouds 03:15Z 49 46 36 78 (ENE) -9999 - clouds 03:47Z 48 45 25 61 (ENE) -9999 - clouds 04:19Z 47 44 32 80 (E) -9999 - clouds 04:52Z 47 45 23 70 (ENE) -9999 - clouds 05:24Z 47 47 14 58 (ENE) -9999 - clouds 05:56Z 48 47 5 12 (NNE) -9999 - clouds 06:28Z 48 47 10 42 (NE) -9999 - clouds 07:00Z 49 48 5 131 (SE) -9999 - clouds 07:32Z 49 48 11 81 (E) -9999 - clouds 08:04Z 49 48 11 136 (SE) -9999 - clouds 08:37Z 48 48 2 135 (SE) -9999 - clouds 09:09Z 48 48 8 104 (ESE) -9999 - clouds 09:41Z 47 48 5 98 (E) -9999 - clouds ---=== TELESCOPE STATUS ===--- No interlocks bypassed.
