Again, simply restarting the nubs for dcam fixed the problem. No other problems. A nice clear night and the seeing improved during the 2nd half as well. ------- 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 -------------------------------------------------------------------------- 19:02 dcamera 549( 493) 123 65 5.3 5.8 5.0 5.8 4.9 -- 1.30 20:01 dcamera 403( 317) 29 54 4.7 4.9 5.1 4.8 4.6 -- 1.40 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp C Dewp C MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 42 18 24 297 (WNW) 1375 cloudy none 17:00 42 21 14 266 (W) 786 cloudy none 18:00 43 21 23 300 (WNW) 1461 ptly cldy lt snow 19:00 41 22 18 308 (NW) 1224 mstly clr none 20:00 41 20 23 312 (NW) 693 clear none 21:00 40 20 23 302 (WNW) 628 clear none 22:00 41 20 20 319 (NW) 750 clear none 23:00 40 20 16 297 (WNW) 681 clear none 00:00 38 22 16 350 (N) 561 clear none 01:00 39 21 0 262 (W) 662 clear none 02:00 38 22 9 338 (NNW) 621 clear none 03:00 38 22 16 301 (WNW) 627 clear none 04:00 38 21 14 317 (NW) 798 clear none 05:00 38 20 16 318 (NW) 876 clear none Note: the wind was coming from the azimuth listed.
