A nub restart and init brought the numbers back down to normal the dropped quads to zero. I began trying to bring the quads back but it wasn't until I increased the temp to 199K and waited 5 min that a power cycle of the Leech controller finally worked. I fear this will happen again tomorrow. Weather was clear for A half but the system that's coming in brought some light clouds for B half. ------- 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 -------------------------------------------------------------------------- 18:09 ecamera 530( -59) -122 33 3.6 5.3 5.0 4.4 4.2 ND2 1.26 00:16 tcamera 465( 960) 16 44 3.5 1.8 3.3 2.6 2.8 Ks 0.99 04:45 tcamera 419( 896) 190 45 3.2 1.4 2.6 2.1 2.6 Ks 1.08 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 42 -7 14 284 (WNW) 506 clear none 17:00 42 -10 10 264 (W) 508 clear none 18:00 38 -4 7 264 (W) 634 clear none 19:00 38 -2 8 233 (SW) 783 clear none 20:00 38 -1 10 211 (SSW) 871 clear none 21:00 38 1 14 223 (SW) 910 clear none 22:00 38 1 13 227 (SW) 1049 clear none 23:00 39 -5 15 234 (SW) 640 clear none 00:00 39 -8 13 239 (WSW) 583 clear none 01:00 39 -8 12 258 (WSW) 556 clear none 02:00 39 -9 10 248 (WSW) 563 mstly clr none 03:00 39 -4 12 241 (WSW) 697 mstly clr none 04:00 38 -1 18 236 (SW) 1250 mstly clr none 05:00 36 -2 19 229 (SW) 1213 clear none 06:00 37 -4 23 234 (SW) 1235 clear none Note: the wind was coming from the azimuth listed.
