APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday January 26, 2009 (MJD 54858) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev Audrey Simmons Steph Snedden (swing) Connie Rockosi (support) ---=== OBSERVING PLAN ===--- 26 Jan 2009 54858.0 0.06 BOSS/SEGUE 10.7 hours ---=== OBSERVING SUMMARY ===--- Clouds, wind, and humidity kept us closed all night. We completed the very sparse-plugged test. Imager ion pump pressure gave us a scare tonight. Please see log for more details. ---=== OBSERVING LOG ===--- Afternoon: ---------- Changed spectro focus a little to match an air temp of 3 to 4 C. No problems noted during afternoon checkout. Removed MJD 54831, 54832 data from sdsshost2/sdssfiles1. The disk space is now: /dev/sdb1 917G 834G 37G 96% /data sdssfiles1p:/data1/data 1.5T 817G 576G 59% /files Ventilation delayed because of high dust counts and overcast skies. Night: ----- 00:30Z - Wind gusts to 44mph. Thick cloud cover. 01:46Z - Mounted cart 9, plate 3209 for the very sparse plug test. Bias 58424 Precal sequence 58425-26 2 sec arc with HgCd 58429 40 sec arc with HgCd 58430 2 sec arc with Ne 58431 40 sec arc with Ne 58432 2 sec arc with HgCd 58433 40 sec arc with HgCd 58434 2 sec arc with Ne 58435 40 sec arc with Ne 58436 Bias 58437 Bias 58438 03:51Z - Still have high winds and lots of clouds, but low dust counts. We started ventilating. 05:48Z - Watcher errors for ln2 empty (2009-01-27 05:35:53Z). Moved the telescope back to 30 and hooked up the LN2 lines. The fill started right away. 08:30Z - Ion imager pressure exceeded 2 torr, then bounced between 2.5 and 2.9 torr. Connie was notified. 08:55Z - The ion pressure dropped drastically, from 2.5 to 0.7 torr. A fill occured a few minutes ago. Coincidence? 09:15Z - Humidity rose above the limit. We stopped ventilating. Remounted cart 4, plate 3170. 11:47Z - Dew point difference at 1.2 and thick clouds overhead. We called it a night. 11:50Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7934 21:52Z 22:07Z 100 O 161.86 171.5 39 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 23:22 58420 10.0 flat 23:25 58421 2.0 arc ----- sequence 58422, plate -9999 ------- 23:36 58422 0.0 bias 23:52 58423 0.0 bias ----- sequence 58424, plate 3209 ------- 01:49 58424 0.0 bias 01:53 58425 10.0 flat 01:56 58426 2.0 arc 02:02 58427 10.0 flat 02:04 58428 2.0 arc 02:12 58429 3.0 target 02:18 58430 41.0 target 02:23 58431 3.0 target 02:32 58432 41.0 target 02:37 58433 2.0 engineering 02:41 58434 40.0 engineering 02:55 58435 2.0 engineering 03:00 58436 40.0 engineering 03:02 58437 0.0 bias 03:05 58438 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 22:42Z 41 13 29 221 (SW) 1333 - Cloudy, dusty, windy 23:14Z 40 13 26 244 (WSW) 1115 - " 23:46Z 40 17 28 225 (SW) 3668 - " 23:54Z 40 18 21 227 (SW) 3713 - " 00:28Z 39 19 36 217 (SW) 4181 - " 01:00Z 38 20 30 221 (SW) 3980 - " 01:32Z 38 19 23 252 (WSW) 2588 - Cloudy, windy 02:04Z 38 19 36 218 (SW) 2232 - " 02:36Z 37 19 28 225 (SW) 1585 - " 03:06Z 37 18 32 223 (SW) 1177 - " 03:36Z 37 18 31 241 (WSW) 955 - " 04:07Z 36 17 30 241 (WSW) 805 - " 04:37Z 36 15 19 245 (WSW) 580 - " 05:07Z 35 17 26 232 (SW) 561 - " 05:40Z 35 18 30 237 (WSW) 593 - " 06:12Z 35 18 33 231 (SW) 555 - " 06:44Z 34 18 21 218 (SW) 544 - " 07:16Z 34 21 30 209 (SSW) 696 - Cloudy 07:48Z 33 24 22 233 (SW) 662 - " 08:20Z 33 25 22 202 (SSW) 631 - " 08:53Z 32 26 19 199 (SSW) 613 - Cloudy, humid 09:25Z 32 27 23 217 (SW) 606 - " 09:57Z 31 27 18 210 (SSW) 617 - " 10:29Z 31 27 18 235 (SW) 570 - " 11:01Z 30 27 11 260 (W) 607 - " 11:34Z 29 26 11 266 (W) 845 - ---=== TELESCOPE STATUS ===--- Ventilation delayed due to high dust counts. 03:51Z - Began ventilation.
