We were able to make use of a hole during first half to observe one target successfully before the clouds thickened again. During second half we also tried for a while, but the targets were fainter so the clouds had more effect. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 22:03 tcamera 455( 1194) 7 73 11.5 12.7 13.0 12.7 11.6 Ks 1.23 04:08 dcamera 473( 755) 270 53 8.2 9.3 9.8 9.4 8.6 - 1.30 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 59 15 13 198 (SSW) 356 cloudy none 17:00 58 14 20 201 (SSW) 389 cloudy none 18:00 56 13 18 216 (SW) 453 mstly cldy none 19:00 56 14 14 193 (SSW) 682 mstly cldy none 20:00 54 15 16 178 (S) 656 mstly cldy none 21:00 52 22 14 182 (S) 667 ptly cldy none 22:00 53 20 12 181 (S) 598 ptly cldy none 23:00 53 19 17 189 (S) 581 mstly cldy none 00:00 51 21 16 184 (S) 786 mstly cldy none 01:00 50 27 17 199 (SSW) 980 cloudy lt rain 02:00 48 27 23 207 (SSW) 919 cloudy none 03:00 48 26 15 205 (SSW) 914 mstly cldy none 04:00 47 26 17 228 (SW) 1118 mstly cldy none 05:00 45 31 18 213 (SSW) 1401 mstly cldy none 06:00 43 29 15 240 (WSW) 1161 mstly cldy none Note: the wind was coming from the azimuth listed.
