Unfortunately, Apollo was having some issues when Russet attempted the first fire. We tried trouble shooting but to no avail. The clouds cleared and seeing improved, and then clouds came back and seeing degraded. And then it improved and then more clouds. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- APO1 Apollo I/U 17:29 18:13 Laser failed to fire ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 17:21 APOLLO 300( 1231) -33 35 37.3 3.8 3.4 3.6 1.4 530 1.80 18:22 arctic 380( 515) -155 48 37.3 1.6 2.5 1.9 1.5 S-II 0.94 19:14 arctic 469( 575) -152 43 37.3 0.9 1.8 1.1 1.3 H-Alpha 1.04 21:31 arctic 456( 567) 194 61 37.3 1.3 2.5 2.0 1.9 S-II 0.91 22:39 arctic 441( 528) 206 56 37.3 0.7 1.7 0.9 -0.1 S-II 1.64 00:23 kosmos 542( 603) 67 60 37.3 1.3 2.6 1.6 3.0 -- 1.29 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 99 32 8 223 (SW) 329 ptly cldy none 17:00 99 32 2 351 (N) 272 ptly cldy none 18:00 99 32 6 2 (N) 115 ptly cldy none 19:00 99 32 6 353 (N) 160 mstly clr none 20:00 99 32 7 341 (NNW) 127 ptly cldy none 21:00 99 32 4 61 (ENE) 79 mstly clr none 22:00 99 32 4 44 (NE) 175 clear none 23:00 99 32 5 342 (NNW) 108 clear none 00:00 99 32 7 346 (NNW) 112 mstly clr none 01:00 99 32 6 344 (NNW) 115 mstly clr none 02:00 99 32 6 343 (NNW) 98 mstly clr none 03:00 99 32 3 243 (WSW) 113 mstly clr none 04:00 99 32 4 252 (WSW) 97 ptly cldy none 05:00 99 32 11 263 (W) 124 ptly cldy none 06:00 99 32 11 264 (W) 97 ptly cldy none Note: the wind was coming from the azimuth listed.
