I had to force quit and restart my TUI. Humidity was borderline closure when we started the 2nd half tonight. The cold front was hitting us and the temps were dropping. about 50 mins into the 2nd half program humidity, and clouds forming over us, closed us down. I had an failed echelle calfiter when I went to do my end of night Echelle IOL images. I manually moved things and this seemed to clear the error for the script to run. We gave up at 06:13 with humidity too high to open. ------- 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 -------------------------------------------------------------------------- 18:40 ecamera 391( 78) 87 68 5.7 8.3 8.2 7.8 6.6 ND1 1.01 23:29 ecamera 221( -327) 238 80 4.0 3.4 3.9 3.3 3.2 ND2 0.76 01:05 kosmos 418( 826) 138 56 0.4 1.1 2.6 1.1 1.3 1.48 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 51 31 16 224 (SW) 971 mstly clr none 17:00 50 31 12 259 (W) 941 clear none 18:00 47 32 11 237 (WSW) 1010 clear none 19:00 43 33 13 225 (SW) 986 ptly cldy none 20:00 41 33 9 254 (WSW) 1144 cloudy none 21:00 38 32 8 234 (SW) 1260 ptly cldy none 22:00 36 32 7 214 (SW) 1313 ptly cldy none 23:00 36 32 4 133 (SE) ptly cldy none 00:00 36 31 4 189 (S) 950 clear none 01:00 33 30 1 220 (SW) mstly clr humid 02:00 32 29 2 190 (S) cloudy humid 03:00 32 30 1 212 (SSW) cloudy humid 04:00 31 30 1 210 (SSW) cloudy humid 05:00 30 30 2 342 (NNW) ptly cldy humid 06:00 31 30 1 292 (WNW) clear humid Note: the wind was coming from the azimuth listed.
