The telescope struggled a little tracking downward into a 25-28 mph west wind, but it was winning the struggle and delivering good images so there was no need to close. ------- 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 -------------------------------------------------------------------------- 17:32 dcamera 496( 439) 14 51 6.4 8.4 8.6 7.9 7.3 - 1.36 00:24 arctic 526( 483) -21 55 6.6 6.0 6.4 6.0 6.1 660 0.85 00:29 arctic 546( 506) -23 55 6.2 5.9 6.4 6.1 6.1 r 0.98 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp C Dewp C MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 49 14 10 242 (WSW) 91 mstly cldy none 17:00 44 15 9 265 (W) 134 mstly cldy none 18:00 44 18 19 268 (W) 206 mstly cldy none 19:00 44 15 15 256 (WSW) 188 mstly clr none 20:00 45 12 20 270 (W) 152 mstly clr none 21:00 44 11 23 275 (W) 123 mstly clr none 22:00 44 11 24 264 (W) 121 mstly clr none 23:00 43 12 17 265 (W) 130 mstly clr none 00:00 43 15 21 266 (W) 237 mstly clr none 01:00 43 15 16 264 (W) 310 mstly clr none 02:00 43 15 15 272 (W) 260 mstly clr none 03:00 42 15 13 270 (W) 250 ptly cldy none 04:00 42 15 16 276 (W) 290 ptly cldy none 05:00 42 13 19 284 (WNW) 174 ptly cldy none 06:00 42 13 19 266 (W) 128 ptly cldy none Note: the wind was coming from the azimuth listed.
