We stayed closed for a few hours at the start of the night due to radar and a tiny bit of light snow around 19:30. Everything cleared up and we opened at 20:00 to pretty good seeing and no more clouds or radar or problems for the rest of the night. ------- 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 -------------------------------------------------------------------------- 20:14 ecamera 317( -454) 38 73 1.6 1.8 3.2 2.4 2.3 ND2 0.78 22:51 tcamera 420( 848) 314 54 1.2 0.5 1.4 0.8 1.0 Ks 1.25 00:18 APOLLO 475( 1414) 305 65 0.9 0.2 0.9 0.5 0.6 530 1.60 01:23 tcamera 472( 876) 99 53 0.6 -0.0 0.6 -0.1 0.1 Ks 1.02 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 38 20 15 282 (WNW) 1559 ptly cldy none 17:00 37 20 10 263 (W) 1220 ptly cldy none 18:00 35 16 11 264 (W) 1530 mstly cldy none 19:00 35 18 14 269 (W) 1388 mstly cldy lt snow 20:00 35 17 13 265 (W) 1797 mstly clr none 21:00 34 18 14 266 (W) 1514 mstly clr none 22:00 35 18 19 284 (WNW) 660 clear none 23:00 34 18 12 259 (W) 575 clear none 00:00 34 18 13 267 (W) 584 clear none 01:00 33 18 12 271 (W) 622 clear none 02:00 33 17 22 298 (WNW) 443 clear none 03:00 32 18 21 294 (WNW) 448 clear none 04:00 32 18 17 293 (WNW) 459 clear none 05:00 32 19 26 305 (NW) 408 clear none 06:00 31 20 22 293 (WNW) 342 mstly clr none Note: the wind was coming from the azimuth listed.
