Not a good night for observing; we did not open. ARCSAT had issues communicating and I had to restart the computer, but it wasn't a library support error, just ACP not knowing that the image finished exposing. ------- 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 -------------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 56 19 35 269 (W) 28867 cloudy dust 17:00 56 16 29 261 (W) 34962 cloudy dust 18:00 55 18 27 251 (WSW) 41388 cloudy dust 19:00 54 18 30 261 (W) 40918 cloudy dust 20:00 53 16 19 246 (WSW) 23871 cloudy dust 21:00 53 9 22 274 (W) 16954 cloudy dust 22:00 51 8 15 268 (W) 10081 cloudy dust 23:00 49 10 16 265 (W) 5302 cloudy dust 00:00 48 11 13 271 (W) 4103 cloudy dust 01:00 48 11 15 276 (W) 3556 cloudy none 02:00 47 10 15 264 (W) 3286 cloudy none 03:00 45 8 21 287 (WNW) 3590 cloudy none 04:00 44 2 16 288 (WNW) 2079 cloudy none 05:00 43 1 15 285 (WNW) 2014 cloudy none 06:00 43 2 10 261 (W) 2070 cloudy none Note: the wind was coming from the azimuth listed.
