APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday April 24, 2009 (MJD 54946) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev Dan Oravetz ---=== OBSERVING PLAN ===--- SEGUE Science! ---=== OBSERVING SUMMARY ===--- We were clouded out. The IRSC webpage was not displaying cloud camera images beginning around 08:30Z. The IRSC Control Panel showed images being created continuously with correct time stamps, and the IRSC webpage thought it was updating the images accordingly because the time stamps above the non-images were correct and updating, but there were blank squares where the images should have been. ---=== OBSERVING LOG ===--- Afternoon ========= All systems checked.

Night ===== 01:40Z - Sunset. 03:38Z - Stopped ventilation because of high dust counts and increasing clouds. 08:30Z - IRSC stopped showing images, even though images were being created regularly. zaphod was alive and we tried stopping and restarting the IRSC, but it came back exhibiting the same behavior. Perhaps it's just a hung daemon? The night was lost to clouds again. The satellite photos throughout the night looked as if the clouds were often near clearing, or passing through, but they never did. endNight was run manually and finished fine. 10:37Z - We still had plenty of clouds overhead and with only 16 minutes until twilight, there's no chance of getting data tonight. 10:53Z - Twilight begins. ---=== 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): y QA Procedures Done (y/n): n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 60714, plate -9999 ------- 00:21 60714 0.0 bias ----- sequence 60715, plate 3388 ------- 00:42 60715 10.0 flat 00:45 60716 2.0 arc 00:48 60717 2.0 arc 00:50 60718 3.0 arc ----- sequence 60719, plate -9999 ------- 01:30 60719 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 00:16Z 54 13 24 267 (W) 922 - clouds 00:47Z 54 13 14 252 (WSW) 706 - clouds 01:18Z 53 13 25 266 (W) 729 - clouds 01:49Z 52 12 25 264 (W) 675 - clouds 02:21Z 52 10 18 268 (W) 644 - clouds 02:53Z 50 13 22 295 (WNW) 925 - clouds 03:25Z 50 15 16 290 (WNW) 1917 - clouds 03:57Z 50 15 18 283 (WNW) 1956 - clouds 04:30Z 50 14 14 266 (W) 1189 - clouds 05:01Z 49 13 16 272 (W) 1117 - clouds 05:34Z 50 14 12 264 (W) 888 - clouds 06:04Z 50 13 17 264 (W) 667 - clouds 06:34Z 49 13 18 256 (WSW) 657 - clouds 07:07Z 49 14 21 255 (WSW) 707 - clouds 07:39Z 48 14 18 252 (WSW) 713 - clouds 08:10Z 48 12 21 254 (WSW) 585 - clouds 08:43Z 47 10 19 249 (WSW) 585 - clouds 09:13Z 47 8 18 254 (WSW) 548 - clouds 09:44Z 46 8 19 257 (WSW) 507 - clouds 10:16Z 45 7 17 263 (W) 570 - clouds ---=== TELESCOPE STATUS ===--- 01:03Z - Began ventilation.
