Winds were hitting near 60 mph and, once the winds died down to something near 40 mph, we had freezing fog and light snow. Or maybe it was the snow being blown off the trees, I'm not sure... Since there was no hope of opening tonight I called it a bit early. I mounted the new 20" and 1.25" kosmos slits in the wheel and took guider images and flat spectra of them. No problems tonight. ------- 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 31 -9 34 216 (SW) cloudy none 17:00 31 -10 32 219 (SW) cloudy none 18:00 30 -9 29 245 (WSW) cloudy none 19:00 29 -8 32 256 (WSW) cloudy none 20:00 26 -7 20 257 (WSW) cloudy none 21:00 22 3 28 269 (W) cloudy humid 22:00 18 16 31 281 (W) cloudy fog 23:00 15 14 32 265 (W) cloudy fog 00:00 13 11 33 236 (SW) cloudy lt snow 01:00 11 10 31 261 (W) cloudy fog Note: the wind was coming from the azimuth listed.
