The winds gusted near 70mph during the day and we had high dust and humidity at night. Once the wind calmed down, it was just high humidity and fog the rest of the night and possible some snow flurries. I called it at 4:30. 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 27 14 26 263 (W) 14622 cloudy humid 17:00 28 15 40 259 (W) 19388 cloudy humid 18:00 26 18 36 281 (W) 12261 cloudy humid 19:00 26 15 35 282 (WNW) 8074 cloudy humid 20:00 24 18 24 262 (W) 6333 cloudy humid 21:00 22 19 20 266 (W) cloudy humid 22:00 21 20 24 269 (W) cloudy humid 23:00 21 18 24 269 (W) cloudy humid 00:00 20 19 16 262 (W) cloudy humid 01:00 20 19 15 265 (W) cloudy humid 02:00 20 19 12 265 (W) cloudy fog 03:00 19 18 13 264 (W) cloudy fog 04:00 19 18 13 287 (WNW) cloudy fog Note: the wind was coming from the azimuth listed.
