PMSS plots were frozen but stripcharts and the mac were still ok--I had to power cycle dataq from hub35m to get them going again. Froze again about an hour later and power cycling dataq (twice) didn't work, TCP/IP manager still said PMSS is Off Line. Agile inst block from last night was rotated by about 180 degrees, and with the very high image cadence the hub lagged in writing images which caused at least one 5 minute gap in data. ------- 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 -------------------------------------------------------------------------- 23:02 kosmos 290( 688) 49 47 3.2 1.9 3.5 2.6 2.7 -- 0.88 01:24 ecamera 403( -232) 16 55 2.9 1.3 2.6 2.0 2.2 Clear 1.16 03:09 kosmos 340( 714) 29 42 3.1 1.3 2.6 1.9 2.6 Clear 1.06 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 46 15 17 267 (W) 787 clear none 17:00 45 12 7 267 (W) 776 clear none 18:00 46 14 2 283 (WNW) 841 clear none 19:00 43 9 13 302 (WNW) 1097 clear none 20:00 40 7 6 329 (NNW) 1254 clear none 21:00 41 8 3 296 (WNW) 1208 clear none 22:00 38 14 7 186 (S) 1141 clear none 23:00 38 14 10 188 (S) 2327 clear none 00:00 38 12 10 195 (SSW) 2347 clear none 01:00 37 10 12 211 (SSW) 1872 clear none 02:00 37 9 8 264 (W) 1501 clear none 03:00 37 9 10 267 (W) 1328 clear none 04:00 37 9 8 263 (W) 1254 clear none 05:00 37 8 7 252 (WSW) 1297 clear none 06:00 38 8 10 263 (W) 1379 clear none Note: the wind was coming from the azimuth listed.
