I ran the snow program for several hours, but here was very little accumulation before morning. I parked the telescope facing south to take advantage of any sunshine during the day. ------- 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 31 21 25 268 (W) 67281 cloudy dust 17:00 25 27 27 294 (WNW) cloudy dust 18:00 24 27 24 272 (W) cloudy humid 19:00 22 25 23 275 (W) cloudy humid 20:00 21 24 18 271 (W) cloudy humid 21:00 20 22 22 280 (W) cloudy fog 22:00 19 19 22 274 (W) cloudy fog 23:00 19 14 18 265 (W) 175 cloudy lt snow 00:00 20 14 14 271 (W) 496 cloudy lt snow 01:00 18 14 20 270 (W) 2893 cloudy lt snow 02:00 17 14 25 268 (W) 6604 cloudy lt snow 03:00 17 17 20 269 (W) cloudy lt snow 04:00 17 17 15 262 (W) cloudy lt snow 05:00 16 19 15 265 (W) cloudy lt snow Note: the wind was coming from the azimuth listed.
