APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday September 6, 2006 (MJD 53985) ---=== OBSERVING TEAM ===--- Steph Snedden Kaike Pan (afternoon assist) Jian Ge (UF) Pengchang Guo (UF) Support: French Leger ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- More humidity. More spectro autofill craziness. No science. ---=== OBSERVING LOG ===--- Afternoon: ---------- There were no problems this afternoon with DA archiving of a test bias. The 89 degree Alt fiducial read going down, but it took two tries. The 75 degree alt fiducial continued to not read in either direction. The 60 degree alt fiducial took two tries to read going down, but did read successfully, and read on the first try going up. No other problems noted during checkout, but the spectrographs could not be checked, since cartridges are plugged for the ET interferometer. Night: ------ As soon as the sun went down, the dewpoint depression went under 1C. Unfortunately, the sky was mostly clear. We waited. During this time, Jian, Pengchang, French and Steph checked and cleaned some of the ET fibers with lower throughput. One fiber was found to be broken on cartridge 7 (? I think it was 7). 01:20Z - The spectro autofill started going wonky. The fill cycle became very short and irregular, filling on average every 15 minutes and taking ten to twenty pounds of LN2 at each fill. French watched it for a while, then switched from autofill to manual fill at 05:20Z. He forced a fill, and requested that I not force another fill at the end of the night, if at all possible, so that he and Wendell could start work on the system in the morning with mostly empty dewars. 06:42Z - Humidity still high, and now there's radar return nearby. 09:35Z - Humidity still high and cloudy. 11:38Z - I give up. No spectro LN2 fill was forced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6303 00:17Z 00:26Z 100 O 59.51 61.67 29 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):n QA Procedures Done (y/n):n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 40587, plate -9999 ------- 00:19 40587 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 23:48Z 57 49 8 264 (W) 305 - most clear 00:19Z 56 49 9 240 (WSW) 330 - ' 00:51Z 53 49 5 213 (SSW) 378 - ' 01:23Z 50 48 2 186 (S) 301 - ' 01:55Z 49 47 5 101 (E) 351 - ' 02:28Z 49 46 1 107 (ESE) 407 - ' 03:00Z 48 47 7 120 (ESE) 416 - ' 03:32Z 49 45 8 133 (SE) 384 - part cloudy 04:04Z 48 47 5 149 (SSE) 393 - ' 04:35Z 48 48 3 132 (SE) 471 - ' 05:05Z 48 47 6 153 (SSE) 506 - ' 05:35Z 48 45 4 180 (S) 536 - ' 06:06Z 48 46 7 63 (ENE) 527 - 06:37Z 48 44 1 58 (ENE) 423 - 07:08Z 48 45 2 191 (S) 437 - most cloudy 07:38Z 48 45 5 187 (S) 556 - ' 08:10Z 47 45 5 184 (S) 582 - ' 08:40Z 47 46 6 185 (S) 625 - ' 09:10Z 47 46 6 187 (S) 730 - ' 09:41Z 47 46 6 190 (S) 654 - ' 10:11Z 47 45 4 189 (S) 596 - ' 10:41Z 47 45 7 229 (SW) 606 - ' 11:11Z 47 45 3 257 (WSW) 698 - ' 11:41Z 47 46 4 269 (W) 683 - ' ---=== TELESCOPE STATUS ===--- Never ventilated.
