But the humidity was at or over the limit for first half, and when it dropped the wind picked up to over 30 mph, so we did not have a chance to open. A power flicker in the evening caused a problem with the dome controller, but it recovered with a hard reset. I ran the snow program until the wind picked up, then I parked facing southwest to get extra sunlight on the left side of the dome but still some on the right side. ------- 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 14 11 2 288 (WNW) ptly cldy humid 17:00 13 9 5 315 (NW) mstly clr humid 18:00 12 8 15 9 (N) clear humid 19:00 12 8 12 27 (NNE) clear humid 20:00 11 7 16 11 (N) clear humid 21:00 12 6 14 0 (N) clear humid 22:00 10 7 12 25 (NNE) clear humid 23:00 9 7 27 15 (NNE) clear humid 00:00 10 6 15 8 (N) clear none 01:00 9 6 26 24 (NNE) clear none 02:00 9 4 26 15 (NNE) clear none 03:00 9 3 16 14 (NNE) clear none 04:00 9 1 27 28 (NNE) clear none 05:00 10 -3 22 16 (NNE) clear none Note: the wind was coming from the azimuth listed.
