We had a partial clearing at the very end of the night. Unfortunately a fog bank was also located just to our east, along with an east wind, so I did not feel comfortable opening for APOLLO. ------- 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 63 32 1 63 (ENE) ptly cldy none 17:00 67 31 1 212 (SSW) 412 ptly cldy none 18:00 70 31 6 269 (W) 318 cloudy none 19:00 67 31 4 250 (WSW) 364 cloudy none 20:00 64 31 6 183 (S) 597 cloudy none 21:00 63 31 1 223 (SW) 731 cloudy lt rain 22:00 61 31 4 92 (E) 698 cloudy none 23:00 62 31 4 139 (SE) 584 cloudy lt rain 00:00 59 31 7 170 (S) 731 cloudy lt rain 01:00 56 30 5 258 (WSW) 906 cloudy lt rain 02:00 56 30 7 268 (W) 329 cloudy lt rain 03:00 57 30 4 340 (NNW) 343 cloudy none 04:00 60 31 3 290 (WNW) 151 cloudy none 05:00 60 31 7 83 (E) 402 ptly cldy none Note: the wind was coming from the azimuth listed.
