APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday September 6, 2007 (MJD 54350) ---=== OBSERVING TEAM ===--- Day: Kaike Pan Night: Dmitry Bizyaev, Steph Snedden ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- High humidity, with occasional bouts of fog and cloud to break the monotony. ---=== OBSERVING LOG ===--- Afternoon: ----------- Spectro focus was checked, it was set for about 14 C. We got ntp warning email message said that ad4 had a time sync problem, Fritz knew this and replied the messge saying it was okay at the moment. we are keeping check the time sync, and found the delay of ad4 was increasig, at 01:45Z, it was about 125 ms. We will keep an eye on it. Night: ------ High humidity and fog kept us closed. Toward the end of the night, our hopes were raised, then immediately dashed as the sky started clearing to the east, while simultaneously the clouds in the west gave us a sprinkle of rain. No new hardware / software problems. We still see the TPM communication dropout (see problems section). At the end of the night, ad4's clock was -33 ms off, and back in spec. It drifted back on its own. No science photons tonight. We worked on our own projects and paperwork instead. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6937 23:44Z 00:08Z 100 O 51.02 56.92 53 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 46250, plate -9999 ------- 00:00 46250 0.0 bias ----- sequence 46251, plate 2679 ------- 00:18 46251 10.0 flat 00:20 46252 2.0 arc Focus check 00:29 46253 10.0 flat ' 00:32 46254 2.0 arc ' 00:46 46255 10.0 flat ' 00:48 46256 2.0 arc ' 01:05 46257 10.0 flat ' 01:08 46258 2.0 arc ' 01:11 46259 3.0 arc ' 01:14 46260 2.0 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 22:36Z 52 53 11 252 (WSW) 0 - mostly cloudy 23:12Z 52 53 7 218 (SW) 0 - ' 23:42Z 52 53 10 235 (SW) 0 - ' 00:13Z 53 53 9 197 (SSW) 0 - ' 00:46Z 52 52 10 217 (SW) 0 - ' 01:19Z 52 52 10 211 (SSW) 0 - ' 02:15Z 51 52 8 248 (WSW) 0 - ' 02:47Z 51 52 7 260 (W) 0 - ' 03:20Z 51 51 6 261 (W) 0 - ' 03:52Z 51 51 11 233 (SW) 0 - ' 04:24Z 51 51 8 233 (SW) 0 - ' 04:56Z 52 52 9 247 (WSW) 0 - ' 05:28Z 52 52 2 237 (WSW) 0 - ' 06:00Z 52 52 4 272 (W) 0 - ' 06:33Z 52 52 5 306 (NW) 0 - ' 07:05Z 54 49 2 271 (W) 0 - ' 07:37Z 55 49 6 279 (W) 0 - cloudy 08:09Z 55 49 6 345 (NNW) 0 - ' 08:41Z 54 48 6 359 (NNW) 0 - ' 09:13Z 56 48 6 17 (NNE) 0 - mostly cloudy 09:46Z 56 47 2 47 (NE) 0 - ' 10:18Z 55 46 12 26 (NNE) 0 - cloudy 10:50Z 57 44 15 38 (NE) 0 - ' ---=== TELESCOPE STATUS ===--- Never ventilated, never opened. 11:00Z Telescope stowed at 30 degrees with cart 4 mounted.
