It snowed off an all until about 8pm and then we had high humidity. However, things cleared up nicely and we were able to open at 10:20pm, though we had high humidity for a few hours. Seeing was bad all night but it was spectra and bright targets. No problems tonight. ------- 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 -------------------------------------------------------------------------- 21:26 dcamera 425( 242) -49 77 -1.4 0.5 0.8 0.4 -1.1 -- 1.24 23:23 dcamera 549( 316) 16 53 -0.9 -0.8 -0.4 -1.0 -0.9 -- 1.52 00:10 ecamera 606( -457) 130 31 -0.2 -0.7 -0.4 -0.7 -0.6 -- 2.21 02:37 ecamera 584( -506) 118 47 -0.4 -1.0 -0.6 -1.1 -0.8 -- 1.72 04:12 ecamera 596( -513) 119 65 -0.4 -1.1 -0.8 -1.3 -0.9 -- 1.35 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 33 21 10 343 (NNW) 490 mstly cldy snow 17:00 35 25 2 260 (W) 396 mstly cldy snow 18:00 33 22 7 287 (WNW) 413 mstly cldy snow 19:00 32 24 3 328 (NNW) mstly cldy lt snow 20:00 31 24 4 301 (WNW) 457 ptly cldy lt snow 21:00 31 21 13 346 (NNW) 428 mstly clr humid 22:00 30 24 5 344 (NNW) clear humid 23:00 30 24 15 302 (WNW) clear humid 00:00 31 21 18 298 (WNW) 236 mstly clr none 01:00 31 21 16 276 (W) 367 clear none 02:00 32 21 19 292 (WNW) 344 clear none 03:00 31 22 13 283 (WNW) 358 clear none 04:00 30 22 17 290 (WNW) 324 clear humid 05:00 31 21 23 293 (WNW) 264 clear none 06:00 31 21 18 299 (WNW) 249 clear none Note: the wind was coming from the azimuth listed.
