Then one county over. Then clouds overhead, then radar showing virga on top of us. The system looked like it MIGHT clear out and I was close to re-opening to try again, when wind shifted strongly to the east and humidity spiked, bringing in freezing fog. There was no chance for the remainder of the night. ------- 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 -------------------------------------------------------------------------- 20:28 AGILE 650(-1483) 128 47 6.4 8.0 8.0 7.8 7.1 BG40 1.02 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 49 18 21 232 (SW) 2107 ptly cldy none 17:00 51 19 21 263 (W) 2016 ptly cldy none 18:00 47 18 15 201 (SSW) 2568 mstly clr none 19:00 47 15 14 187 (S) 3091 mstly clr none 20:00 44 13 9 184 (S) 3432 clear none 21:00 43 13 14 149 (SSE) 3397 ptly cldy none 22:00 45 13 12 182 (S) 3165 mstly cldy none 23:00 47 11 15 166 (SSE) 2460 mstly cldy none 00:00 44 11 18 126 (SE) 2590 ptly cldy none 01:00 41 21 17 87 (E) 1654 ptly cldy none 02:00 33 31 29 72 (ENE) 2316 cloudy fog 03:00 31 31 24 80 (E) 14107 cloudy fog 04:00 30 30 29 80 (E) 13006 cloudy fog 05:00 28 28 24 86 (E) 6880 cloudy fog Note: the wind was coming from the azimuth listed.
