And then all of that rain? And then all of those clouds? Nothing. We opened to clear skies at sunset but with poor seeing. We were able to stay open almost an hour before the humdiity rose too high and we had to close. The humidity only got worse and there was no chance of opening again. I called it at 3:30 am. gcam needed a restart during checkout. ------- 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 -------------------------------------------------------------------------- 17:45 kosmos 430( 976) 97 54 2.0 4.1 4.5 4.6 2.8 -- 2.78 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 42 25 9 188 (S) 991 clear none 17:00 38 28 15 149 (SSE) 1423 clear none 18:00 35 31 22 161 (SSE) 1233 clear humid 19:00 35 34 20 133 (SE) clear humid 20:00 35 34 25 127 (SE) clear humid 21:00 35 34 20 141 (SE) clear humid 22:00 36 34 19 122 (ESE) mstly clr humid 23:00 35 34 21 127 (SE) ptly cldy humid 00:00 37 35 17 161 (SSE) cloudy humid 01:00 37 35 17 160 (SSE) cloudy humid 02:00 36 35 20 166 (SSE) mstly cldy none 03:00 35 34 21 152 (SSE) mstly cldy humid Note: the wind was coming from the azimuth listed.
