Skies stated to clear around 1:30 but humidity was still too high, then the winds started around 02:00. My observer gave up at 05:15 as the wind and humidity kept bouncing over the limits. We had snow condensating out of clear sky with 89% humidity at 05:20 as seen on the cloudcam. ------- 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 -------------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 31 30 15 270 (W) 838 mstly cldy humid 17:00 32 28 17 259 (W) 138 cloudy none 18:00 29 28 15 268 (W) 148 cloudy humid 19:00 28 24 19 267 (W) 311 cloudy humid 20:00 27 24 11 287 (WNW) 432 cloudy humid 21:00 26 23 7 274 (W) 350 cloudy humid 22:00 26 25 15 355 (N) 1160 ptly cldy humid 23:00 26 25 10 0 (N) 268 cloudy humid 00:00 24 21 2 329 (NNW) 118 mstly cldy humid 01:00 23 21 20 0 (N) 101 mstly clr humid 02:00 24 19 20 5 (N) 109 clear humid 03:00 25 22 34 18 (NNE) 71 ptly cldy humid 04:00 27 23 34 49 (NE) 336 mstly clr humid 05:00 28 21 23 46 (NE) 263 clear humid Note: the wind was coming from the azimuth listed.
