APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday March 13, 2009 (MJD 54904) ---=== OBSERVING TEAM ===--- Dan Oravetz Audrey Simmons Scott Fleming (MARVELS) Lauren Palladino (MARVLES) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The night was lost due to snow, blowing snow, and high humidity. Scott trained us to use the MARVELS software. Scott wanted us to mount cartridge 5 on the telescope at the end of the night so that he can preform tests tomorrow, but we were unable to because the concrete apron and the mechanical lift were covered in ice and snow. We left the spectro dewer at 75lbs. It should last until tomorrow evening. ---=== OBSERVING LOG ===--- Afternoon: ---------- It was snowing when we arrived. We did not check collimation for SEGUE. No problems during checkout. Night: ------ Did not open/ventilate tonight due to high humidity and snow. 10:47Z - Humidity at 90%, dew point at 1.4, lots of blowing snow, and the telescope apron is completely covered in ice. There is no hope of opening. 10:48Z - endNight rejoiced. ---=== 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 59655, plate -9999 ------- 23:50 59655 0.0 bias 23:55 59656 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 23:51Z 28 26 6 281 (W) 336 - 00:23Z 27 27 0 263 (W) 282 - 00:55Z 28 26 0 189 (S) 438 - 01:27Z 27 25 6 88 (E) 329 - 01:59Z 25 24 7 84 (E) 100 - 02:31Z 26 23 2 229 (SW) 136 - 03:03Z 27 23 5 263 (W) 206 - 03:36Z 27 24 7 277 (W) 405 - 04:08Z 27 24 4 267 (W) 381 - 04:40Z 28 23 5 270 (W) 413 - 05:12Z 28 23 9 267 (W) 437 - 05:44Z 27 23 8 268 (W) 562 - 06:16Z 28 24 6 274 (W) 587 - 06:48Z 28 24 5 265 (W) 631 - 07:21Z 28 24 6 268 (W) 616 - 07:53Z 27 24 6 269 (W) 581 - 08:25Z 27 24 5 317 (NW) 582 - 08:57Z 27 24 11 326 (NW) 515 - 09:29Z 27 24 11 301 (WNW) 467 - 10:01Z 27 25 11 322 (NW) 426 - 10:33Z 27 25 14 323 (NW) 363 - ---=== TELESCOPE STATUS ===--- We never opened nor ventilated.
