APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday June 13, 2009 (MJD 54996) ---=== OBSERVING TEAM ===--- Howard Brewington Dmitry Bizyaev ---=== OBSERVING PLAN ===--- SEGUE2 and MARVELS Science! ---=== OBSERVING SUMMARY ===--- The night was totally lost due to clouds, high dust count and rain. We expect the spectro dewars wil get next fill 'round the noon, so we leave the spectro LN2 dewar with 110 lbs in the morning, and will replace it tomorrow evening. ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:00Z Restarted the watcher servers. 23:33Z [hjbrew@sdsshost2 hjbrew]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 119G 16G 89% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 761G 110G 88% /data sdssfiles1p:/data1/data 1.5T 605G 788G 44% /files 23:34Z Spectro focus was checked and adjusted. i.e., sp1 by +4000 and sp2 by +3500. It's set for about 19-degrees C, and the collimate numbers are posted in the Problem Section. 23:50Z Completed the apo_plotbias; results posted in Prob Section 02:12Z Sunset with clouds and nearby radar returns, so we waited. Ventilation delayed because of high dust count (up tp 18000). Night: ------- 04:30Z dust count dropped below the red limit. Nevertheless, we have overcasted sky and nearby radar returns. Still closed. 05:00Z cloudy, but not dusty. We started ventilation. 06:10Z we see very rare drops on cloud cam (but rain sensor doesn't give an alert yet). Ventilation stopped, doors closed, louvers closed. 07:55Z rain sensor gives the rain alarm 09:30Z rain is getting only heavier 09:43Z endNight finished ---=== 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 61657, plate 3367 ------- 23:24 61657 0.0 bias 23:35 61658 10.0 flat 23:38 61659 2.0 arc 23:49 61660 3.0 arc 23:51 61661 3.0 arc ----- sequence 61662, plate -9999 ------- 01:29 61662 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 23:25Z 65 26 17 260 (W) 767 - 23:57Z 66 26 17 275 (W) 710 - 01:53Z 59 29 9 297 (WNW) 10236 - 02:26Z 58 33 8 292 (WNW) 8994 - clouds 02:57Z 57 33 6 305 (NW) 16180 - '' 03:30Z 57 34 12 297 (WNW) 9617 - '' 04:01Z 56 34 9 266 (W) 4897 - '' 04:31Z 56 35 8 350 (NNW) 2734 - '' 05:03Z 56 35 12 325 (NW) 2499 - '' 05:33Z 56 35 5 326 (NW) 1070 - '' 06:04Z 55 36 11 316 (NW) 930 - ' 06:34Z 55 36 9 353 (NNW) 1671 - '' 07:05Z 55 36 12 359 (NNW) 1561 - '' 07:35Z 55 37 8 0 (N) 1743 - '' 08:08Z 56 35 11 333 (NNW) 445 - '' 08:39Z 56 36 8 344 (NNW) 349 - '' 09:12Z 56 36 8 315 (NW) 534 - '' 09:42Z 54 37 6 2 (N) 470 - ---=== TELESCOPE STATUS ===--- 06:10Z Doors and louvers opened, fans on.
