I restarted kosmos-icc and it worked afterwards. Set camfoc=3000 for ~4C. Thin clouds but not too bad, and improved throughout A-half. NM02 decided to swap instruments from DIS to KOSMOS around sunset and used the start of the night for cals. KOSMOS image write error at 00:15, restarted kosmos-icc again and was able to save the image. Also had to restart (and power cycle) dataq as it had frozen. We had some trouble with clouds during B-half but it cleared back up. KOSMOS cal stage got stuck moving in, I did kosmos status and then re-issued the command to move in and it worked. The B-half observer will be taking cals with KOSMOS until about 08:45 this morning. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- NM02 KOSMOS I/S 00:15 00:30 KOSMOS write image error, reset kosmos-icc ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 21:06 klow 175( 645) 109 64 3.8 5.8 5.7 5.6 5.1 -- 1.02 01:21 kosmos 480( 864) -121 62 4.8 3.9 4.5 4.0 4.2 -- 1.53 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 42 15 4 240 (WSW) 1275 ptly cldy none 17:00 45 20 13 228 (SW) 1222 mstly clr none 18:00 47 20 9 236 (SW) 1183 mstly clr none 19:00 42 20 11 211 (SSW) 1366 mstly clr none 20:00 39 19 18 195 (SSW) 1800 mstly clr none 21:00 38 16 16 185 (S) 1815 clear none 22:00 39 15 13 192 (SSW) 1703 clear none 23:00 39 17 10 208 (SSW) 1405 clear none 00:00 40 18 14 221 (SW) 1529 mstly clr none 01:00 41 19 13 216 (SW) 1626 mstly clr none 02:00 40 19 13 212 (SSW) 1528 mstly cldy none 03:00 40 19 15 210 (SSW) 1551 ptly cldy none 04:00 40 21 17 230 (SW) 1629 mstly clr none 05:00 39 19 17 239 (WSW) 1557 mstly clr none 06:00 37 18 14 222 (SW) 1484 mstly clr none Note: the wind was coming from the azimuth listed.
