Clouds came and went but mostly came all night long. Weather predicition was clear and it looked like we were right on the edge of the clearing, but clouds just rolling in from the west. We also had a very light dusting of snow and at the end of the night fog as the skies finally did clear around 04:00, the temp dropped, and the humidity shot up past the closure limits (and we had fog). ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEGDFNVO) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 33 20 18 263 (W) 641 Clouds none 17:01 33 20 22 267 (W) 549 Clouds Lt.
