But it moved north and we didn't have to close. Seeing was moderate all night and things cleared up quite nicely for second half. 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 -------------------------------------------------------------------------- 18:46 dcamera 380( 398) 156 67 3.2 5.4 5.4 5.4 3.4 -- 1.15 19:11 dcamera 406( 395) 165 69 3.2 4.7 4.7 4.1 3.1 -- 1.24 21:58 dcamera 516( 395) 38 62 2.9 2.3 3.3 2.7 2.7 -- 1.26 00:17 dcamera 513( 370) 3 61 2.4 1.9 2.9 2.1 2.4 -- 1.12 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 43 6 6 259 (W) 318 mstly clr none 17:00 44 7 9 249 (WSW) 488 mstly clr none 18:00 38 8 8 222 (SW) 533 mstly clr none 19:00 38 8 13 208 (SSW) 597 ptly cldy none 20:00 38 8 12 258 (WSW) 462 ptly cldy none 21:00 37 12 12 304 (NW) 332 mstly cldy none 22:00 38 13 9 271 (W) 252 mstly cldy none 23:00 37 11 11 272 (W) 285 ptly cldy none 00:00 36 13 6 260 (W) 218 mstly clr none 01:00 36 13 8 263 (W) 284 clear none 02:00 33 13 7 254 (WSW) 297 clear none 03:00 33 12 5 259 (W) 291 clear none 04:00 35 13 6 206 (SSW) 294 clear none 05:00 36 12 8 235 (SW) 347 clear none 06:00 35 13 7 267 (W) 379 clear none Note: the wind was coming from the azimuth listed.
