Restarted computer. Lots of radar nearby for A-half and the start of B-half. We got light snow flurries for a little while after 22:00, and clouds on and off all night. It was too humid to open for all of B-half, even after the clouds cleared up. ------- 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 -------------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 43 23 11 261 (W) 1743 cloudy none 17:00 40 24 16 213 (SSW) 1618 cloudy none 18:00 41 24 16 263 (W) 1512 cloudy none 19:00 39 25 13 213 (SSW) 1693 ptly cldy none 20:00 37 26 16 199 (SSW) 2042 ptly cldy none 21:00 37 27 13 184 (S) 2123 ptly cldy none 22:00 37 28 15 184 (S) 2198 mstly cldy lt snow 23:00 37 29 17 202 (SSW) 2196 cloudy lt snow 00:00 33 30 8 258 (WSW) cloudy lt snow 01:00 34 32 13 185 (S) cloudy fog 02:00 33 32 8 255 (WSW) cloudy humid 03:00 32 32 6 264 (W) cloudy humid 04:00 30 30 6 224 (SW) ptly cldy humid 05:00 31 31 3 256 (WSW) mstly clr humid 06:00 30 30 2 179 (S) mstly clr humid Note: the wind was coming from the azimuth listed.
