A night big thunderstorm. While the clouds did clear, it was only for a sucker hole as two storms came over us from opposing directions. And then there was more rain! Which we really need. But a bit sad that we were not able to open on the last night of shut down. ...but maybe that will make things better for the day staff, as that means I didn't break anything! Well, except my heart :( ------- 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 61 44 10 84 (E) 888 cloudy rain 17:00 57 46 13 98 (E) cloudy rain 18:00 65 43 9 88 (E) 1136 cloudy lt rain 19:00 63 46 4 289 (WNW) 1046 mstly cldy none 20:00 63 44 9 188 (S) 1266 mstly cldy none 21:00 63 43 8 89 (E) 1247 ptly cldy none 22:00 65 39 5 93 (E) 1199 cloudy lt rain 23:00 65 38 2 92 (E) 1032 cloudy none 00:00 58 47 22 36 (NE) 1257 cloudy lt rain 01:00 56 48 11 27 (NNE) 1245 cloudy lt rain 02:00 57 46 5 113 (ESE) cloudy lt rain 03:00 57 46 11 147 (SSE) 1109 cloudy none 04:00 57 46 7 160 (SSE) 940 cloudy none 05:00 57 46 3 233 (SW) 868 cloudy none Note: the wind was coming from the azimuth listed.
