The 1-micron dust counts were over 4000 by 19:00 and we stayed closed for the start of the night. Counts came down under 4000 a little before 22:00, so we opened with fans in reverse mode. They never went below 3000, and waffled around the closure limit but since we were pointed out of the wind and the counts inside the enclosure stayed under the limit we stayed open for the rest of A-half. We had to close up a little after the changeover when the dust counts went up. Dust counts stayed too high to reopen and we had additional radar and some rain at the end of the night as well. No secondary resets tonight. Telescope parked at 104,70 for likely rain today. ------- 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 -------------------------------------------------------------------------- 22:00 kosmos 348( 1580) 251 41 18.0 21.5 21.2 21.3 21.1 -- 2.00 01:07 ecamera 771( 726) 302 44 16.3 16.9 18.9 16.4 16.7 ND3 1.03 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 74 50 8 190 (S) 3901 ptly cldy none 17:00 74 48 4 193 (SSW) 3856 ptly cldy rain 18:00 73 47 6 190 (S) 3800 ptly cldy dust 19:00 69 46 9 129 (SE) 4134 mstly clr dust 20:00 67 47 14 148 (SSE) 4575 mstly clr dust 21:00 67 47 13 154 (SSE) 5005 mstly clr dust 22:00 64 44 18 126 (SE) 3692 clear dust 23:00 64 45 16 147 (SSE) 3910 clear dust 00:00 64 44 19 144 (SE) 4163 clear dust 01:00 61 46 19 155 (SSE) 3858 clear dust 02:00 62 48 16 174 (S) 5081 clear dust 03:00 61 48 10 184 (S) 4636 mstly cldy dust 04:00 60 50 8 186 (S) 7070 cloudy dust 05:00 61 49 6 191 (S) 4618 mstly cldy lt rain 06:00 60 49 7 191 (S) 4415 mstly cldy dust Note: the wind was coming from the azimuth listed.
