APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday July 6, 2008 (MJD 54654) ---=== OBSERVING TEAM ===--- Audrey Simmons Howard Brewington Dan Oravetz (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We never opened because of clouds. We did imager cals and completed: getLinearCCD G 5 getLinearCCD G 6 getLinearCCD u 6 getLinearCCD u 5 ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems checked and working properly. sdsshost2.apo.nmsu.edu % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 132G 2.8G 98% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 650G 221G 75% /data sdssfiles1:/data1/data 1.5T 661G 732G 48% /files Spectro focus set for ~14.5C (sp1) and ~12.5C (sp2). Cartridge 3 mounted. Night: ------ 02:13Z Sunset 03:53Z We had clouds at twilight end, so we started imager cals. 03:54Z getLinearCCD G 5, Run #7607, frames 2 to 20. 05:13Z getLinearCCD G 6, Run #7607, frames 21 to 24. We noticed some dark spots on these images. We had a problem after the 4th exposure; exposure five caused the system to pause. We tried restarting the teamster without success. 06:27Z We rebooted the crates and started a new MSP session (Run#7609), yet we then got no return from our pings. 06:36Z Finally, we discovered the laptop had failed, so the calibdata.exe was restarted, and our pings started to work again. Next, we had to edit the linear_g.list by removing the first four exposure commands, which is reflected in the run below. 06:44Z getLinearCCD G 6, Run #7610, frames 2 to 16. This run contains the remaning frames from the run above, viz., getLinCCD G 6, Run #7607. 07:51Z getLinearCCD u 6, Run #7610, frames 17 to 36. 09:09Z getLinearCCD u 5, Run #7610, frames 37 to 55. 10:20Z Morning twilight 10:39Z endNight finished and was happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7606 00:23Z 00:46Z 100 O 0.35 6.03 51 ignore 7611 10:17Z 10:31Z 100 O 149.22 152.75 27 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 00:25 53978 0.0 bias ----- sequence 53979, plate 2901 ------- 00:50 53979 10.0 flat 00:53 53980 2.0 arc 00:57 53981 3.0 arc 01:00 53982 3.0 arc ---=== 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 23:54Z 65 44 12 142 (SE) 1085 - clouds 00:25Z 64 44 10 143 (SE) 1023 - clouds 00:57Z 64 45 11 151 (SSE) 1068 - clouds 08:09Z 58 48 15 150 (SSE) 1580 - 08:41Z 56 49 12 149 (SSE) 1208 - 09:13Z 57 49 15 208 (SSW) 1122 - 09:45Z 56 50 16 180 (S) 763 - 10:17Z 56 50 13 201 (SSW) 686 - ---=== TELESCOPE STATUS ===--- We never opened.
