Seeing was moderate. Second half had clear skies. Around 0230 the wind shifted to east of north and started to become gusty. By 0300, the sustained winds had climbed as well and we closed. Windgusts exceeded 40 miles per hour for the remainder of the second half. We never reopened. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 17:39 Echelle -143(-349) 144 74 1.0/2.9 346 7 nd2 1.09 23:56 dis-slit 75(523) -6 73 -0.4/-0.6 33 3 - 1.26 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 38 16 6 291 (WNW) 282 clear none 17:01 35 16 6 316 (NW) 315 clear none 18:01 34 15 10 327 (NNW) 276 clear none 19:01 34 16 8 315 (NW) 310 clear none 20:01 34 15 10 272 (W) 340 clear none 21:01 34 14 13 301 (WNW) 435 clear none 22:01 33 16 8 300 (WNW) 427 mstly cldy cirrus 23:01 32 17 6 354 (N) 441 mstly cldy cirrus 00:01 31 17 2 9 (N) 472 mstly cldy cirrus 01:01 31 19 18 9 (N) 463 clear none 02:01 32 17 30 19 (NNE) 214 clear none 03:01 33 16 22 38 (NE) 153 clear windy 04:01 35 15 28 21 (NNE) 111 clear windy 05:01 33 16 28 19 (NNE) 180 clear windy Note: the wind was coming from the azimuth listed.
