With our 25 mph wind restriction, we were not able to open until shortly before midnight. We were able to get BY01 a few min on sky, and boy it was a race! Winds gusted back up again while I was chaning instruments and we stayed closed for nearly two hours. However, things finally calmed down and we had good seeing and clear skies for the rest of the night. No problems tonight. ------- 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 -------------------------------------------------------------------------- 23:49 tcamera 250( 126) -65 42 10.0 -7.2 -6.6 -7.1 -8.3 Ks 0.71 01:56 khigh 400( -15) 141 76 10.0 -8.7 -8.2 -8.7 -8.7 -- 1.55 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 23 263 (W) 746 clear none 17:00 15 276 (W) 561 clear none 18:00 18 286 (WNW) 968 ptly cldy none 19:00 16 287 (WNW) 979 mstly cldy none 20:00 32 290 (WNW) 584 mstly cldy none 21:00 28 286 (WNW) 298 ptly cldy none 22:00 24 311 (NW) 313 clear none 23:00 12 316 (NW) 230 clear none 00:00 19 313 (NW) 216 clear none 01:00 19 318 (NW) 122 clear none 02:00 11 305 (NW) 89 clear none 03:00 12 326 (NW) 110 clear none 04:00 11 347 (NNW) 84 clear none 05:00 15 327 (NNW) 107 clear none 06:00 11 356 (N) 94 clear none Note: the wind was coming from the azimuth listed.
