After some light rain in the afternoon, the clouds seemed to be dying. But then rain starting coming from the east and the clouds never cleared. At 4:30am we called it, but UW02 still had a good time! No problems tonight. ------- 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 73 48 10 256 (WSW) 1655 ptly cldy none 17:00 73 45 6 234 (SW) 1680 ptly cldy none 18:00 68 45 13 241 (WSW) 1974 ptly cldy none 19:00 66 48 10 192 (SSW) 1812 ptly cldy lt rain 20:00 65 47 2 188 (S) 1918 mstly cldy none 21:00 64 46 3 195 (SSW) 1833 mstly cldy none 22:00 62 46 1 178 (S) 1932 mstly cldy none 23:00 62 46 5 110 (ESE) 1609 cloudy none 00:00 61 47 11 109 (ESE) 1728 cloudy none 01:00 62 46 10 131 (SE) 1921 cloudy rain 02:00 58 48 18 164 (SSE) 2218 cloudy rain 03:00 57 48 12 177 (S) 2231 cloudy lt rain 04:00 60 46 9 141 (SE) 2098 cloudy none Note: the wind was coming from the azimuth listed.
