Dust and wind was trending down and when they reached yellow-line values, we opened at 20:30. Skies cleared entirely by 23:00 and the wind and dust died down to normal levels. It was clear and calm for the rest of the night, and we remained open. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:36 dcamera 935( 502) 218 60 -0.7 1.1 3.2 1.1 0.2 - 1.89 21:46 dcamera 885( 348) 92 67 -1.1 -0.7 0.4 -0.8 -0.8 - 2.00 00:19 arctic 840( 379) -46 46 -2.5 -2.4 -1.7 -2.4 -2.4 J-C B 1.26 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 37 12 41 261 (W) 3640 mstly clr dust 17:00 37 13 33 256 (WSW) 6937 mstly clr dust 18:00 35 17 19 278 (W) 18155 mstly clr dust 19:00 32 20 17 275 (W) 19238 mstly clr dust 20:00 31 22 19 269 (W) 6264 ptly cldy dust 21:00 31 17 31 270 (W) 1206 ptly cldy none 22:00 30 18 19 263 (W) 1456 mstly clr none 23:00 28 20 16 278 (W) 1567 clear none 00:00 27 20 15 285 (WNW) 609 clear none 01:00 28 20 9 293 (WNW) 340 clear none 02:00 27 18 10 336 (NNW) 336 clear none 03:00 26 8 15 339 (NNW) 203 clear none 04:00 27 4 16 357 (N) 170 clear none 05:00 27 0 8 357 (N) 145 clear none 06:00 31 -7 20 349 (N) 130 clear none Note: the wind was coming from the azimuth listed.
