There was a brief period of clear skies and more-distant radar in the middle of the night which was enough to observe one target for the first half program, but in the second half there was barely enough time to focus and set up on the target field. ------- 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 -------------------------------------------------------------------------- 00:44 arctic 420( 969) 43 44 11.6 12.5 12.8 12.3 11.8 z 0.69 01:22 dcamera 437( 763) 0 61 10.9 11.8 12.2 11.6 11.2 - 1.23 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 57 44 9 276 (W) ptly cldy none 17:00 57 43 6 267 (W) ptly cldy none 18:00 56 43 1 313 (NW) ptly cldy none 19:00 55 45 3 102 (ESE) mstly cldy none 20:00 56 42 1 252 (WSW) mstly cldy none 21:00 55 43 5 144 (SE) mstly cldy none 22:00 54 45 3 98 (E) mstly cldy none 23:00 55 45 8 112 (ESE) ptly cldy none 00:00 54 44 4 190 (S) clear none 01:00 53 42 2 206 (SSW) ptly cldy none 02:00 52 41 2 203 (SSW) mstly cldy none 03:00 52 43 17 141 (SE) mstly cldy none 04:00 51 47 16 150 (SSE) mstly cldy none 05:00 51 49 16 167 (SSE) mstly clr humid Note: the wind was coming from the azimuth listed.
