Had to reset na2-rotator axis controller during afternoon checkout. Cloudy, rainy, foggy all night with high winds and no chance to open. Found water pooled in the typical locations when I went to do morning fills. The spot near the Echelle was fairly large, but doesn't look like any drips got on the telescope. ------- 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 51 47 26 205 (SSW) cloudy humid 17:00 50 47 29 208 (SSW) cloudy humid 18:00 50 49 31 205 (SSW) cloudy rain 19:00 49 49 25 249 (WSW) cloudy rain 20:00 48 49 39 257 (WSW) cloudy rain 21:00 48 48 31 260 (W) cloudy humid 22:00 45 46 32 243 (WSW) cloudy humid 23:00 43 44 26 259 (W) cloudy humid 00:00 42 43 23 250 (WSW) cloudy fog 01:00 42 43 26 242 (WSW) cloudy fog 02:00 43 44 29 245 (WSW) cloudy fog 03:00 43 44 32 258 (WSW) cloudy fog 04:00 43 43 26 270 (W) cloudy fog 05:00 43 43 30 278 (W) cloudy fog Note: the wind was coming from the azimuth listed.
