Seeing wasn't great but after a couple hours everything cleared. Seeing still wasn't great but at least we were open for Christmas! UW04 was feeling particularly giving and, at 3:00 am, donated the rest of their time to WY02. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 17:45 dcamera 434( 377) -68 37 2.0 3.3 3.0 3.0 1.9 -- 1.56 18:32 dcamera 477( 346) -64 33 0.1 1.6 1.9 1.4 0.6 -- 1.78 19:54 dcamera 490( 353) -117 32 2.5 1.5 2.4 1.7 2.1 -- 1.58 22:08 dcamera 497( 340) -133 38 1.9 1.2 2.0 1.5 1.7 -- 1.68 23:13 APOLLO 475( 1104) -40 70 0.8 0.7 1.4 0.8 0.8 530 1.40 00:22 arctic 476( 479) -70 21 0.6 0.4 1.1 0.5 0.8 sdss-r 2.71 03:13 tcamera 492( 703) 49 78 3.7 1.5 2.3 2.1 2.8 MK-s 1.29 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 36 -9 3 249 (WSW) 4135 mstly cldy dust 17:00 35 -11 1 231 (SW) 2599 mstly cldy none 18:00 34 -10 5 261 (W) 2631 ptly cldy none 19:00 37 -8 11 311 (NW) 320 clear none 20:00 37 -8 8 353 (N) 408 clear none 21:00 35 -9 12 25 (NNE) 472 clear none 22:00 36 -4 8 360 (N) 346 clear none 23:00 34 -2 1 32 (NNE) 374 clear none 00:00 33 -1 20 2 (N) 348 clear none 01:00 34 -1 11 6 (N) 290 clear none 02:00 37 -2 15 3 (N) 190 clear none 03:00 39 -5 11 344 (NNW) 64 clear none 04:00 35 -3 12 349 (N) 249 clear none 05:00 34 -2 8 350 (N) 332 clear none 06:00 33 -2 11 353 (N) 231 clear none Note: the wind was coming from the azimuth listed.
