We had a one hour break first half where observers were able to get some data through holes, but they quickly closed and clouds only thickened for the rest of the night, followed by high humidity and precipitation around 4am. No problems. ------- 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 -------------------------------------------------------------------------- 20:55 dis-slit 132( -459) 104 38 -6.3 -4.8 -5.4 -5.5 -5.7 1.80 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------- 16:00 28 14 22 238 (WSW) 368 ptly cldy none 17:00 27 13 15 264 (W) 457 mstly cldy none 18:00 26 12 24 266 (W) 1109 cloudy none 19:00 23 14 14 261 (W) 1058 cloudy none 20:00 22 13 10 273 (W) 2676 cloudy none 21:00 20 13 19 270 (W) 2009 ptly cldy none 22:00 20 12 19 298 (WNW) 1195 ptly cldy none 23:00 20 10 24 297 (WNW) 1022 cloudy none 00:00 19 9 15 271 (W) 983 cloudy none 01:00 18 12 18 275 (W) 949 cloudy none 02:00 18 13 23 277 (W) 945 cloudy none 03:00 16 11 15 277 (W) 1151 cloudy humid 04:00 15 12 13 296 (WNW) 1757 cloudy humid Note: the wind was coming from the azimuth listed.
