APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday September 2, 2008 (MJD 54712) ---=== OBSERVING TEAM ===--- Audrey Simmons Kaike Pan Paul Harding (new guider) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Bad weather got us again. Never open. One Ne lamp (above imager dewer) seems not stable (see log). ---=== OBSERVING LOG ===--- Afternoon: ---------- We have engcam mounted, so spectro focus was not checked this afternoon. The focus should still be at about 12 C, there we left last night. During system checkout, we noticed that one Ne lamp (above imager dewer) fired up 20 sec later than the other three when we turned them on at first time. Then we tried to duplicate it, but all Ne lamps came on immdeiately at about the same time in next four attempts. But one thing we can reproduce is that intensity of that Ne lamp (above the imager dewer) seems not stable. We saw that reflected light from FF screen above the lamp flashing, ie. the intensity seems intermittently weaker/stronger. However, it seems that the lamps was keeping on. All other system checked and work properly. Night: ------ 01:50Z id1 was done, photo crates were rebooted. 10:30Z endNight finished quickly. 11:00Z replaced spectro dewar. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7669 23:48Z 10:31Z 100 O 48.68 -150.08 36 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 54457, plate -9999 ------- 23:46 54457 0.0 bias 00:17 54459 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 ------------------------------------------------------------------------------ 23:39Z engcam 1.00000 1 -2605 0 121 30.0 14.4 10 60 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:24Z 56 49 15 68 (ENE) -9999 - 22:56Z 57 48 14 75 (ENE) -9999 - 23:28Z 58 48 12 71 (ENE) -9999 - 00:29Z 54 50 12 76 (ENE) -9999 - 01:01Z 52 49 17 73 (ENE) -9999 - 01:34Z 51 48 15 68 (ENE) -9999 - 02:04Z 50 48 20 69 (ENE) -9999 - 02:34Z 50 48 22 72 (ENE) -9999 - 03:06Z 49 47 26 70 (ENE) -9999 - 03:38Z 48 47 22 73 (ENE) -9999 - 04:10Z 48 47 18 67 (ENE) -9999 - 04:42Z 47 48 17 74 (ENE) -9999 - 05:15Z 47 47 10 73 (ENE) -9999 - 05:47Z 47 47 19 76 (ENE) -9999 - 06:19Z 47 47 15 74 (ENE) -9999 - 06:51Z 47 47 6 76 (ENE) -9999 - 07:23Z 47 47 11 80 (E) -9999 - 07:55Z 46 47 16 78 (ENE) -9999 - 08:25Z 46 47 9 83 (E) -9999 - 08:56Z 45 46 9 83 (E) -9999 - 09:26Z 46 46 10 76 (ENE) -9999 - 09:56Z 46 46 14 74 (ENE) -9999 - 10:26Z 46 46 11 75 (ENE) -9999 - 10:56Z 45 45 9 76 (ENE) -9999 - 11:28Z 45 46 13 74 (ENE) -9999 - 12:01Z 45 46 8 80 (E) -9999 - ---=== TELESCOPE STATUS ===--- never open.
