The OU class got to take cals and slew the telescope with the dome closed, but we didn't get on sky. We gave up at 04:30. No telescope or instrument problems. ------- 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 52 22 27 246 (WSW) 10897 ptly cldy dust 17:00 50 23 25 272 (W) 7356 mstly cldy dust 18:00 50 23 27 264 (W) 7772 mstly cldy dust 19:00 48 24 38 257 (WSW) 7568 mstly cldy dust 20:00 48 24 28 262 (W) 8019 mstly cldy dust 21:00 46 23 32 259 (W) 15150 mstly cldy dust 22:00 43 26 26 263 (W) 8480 cloudy dust 23:00 41 27 24 288 (WNW) 9983 cloudy dust 00:00 39 27 24 267 (W) 7534 cloudy dust 01:00 37 27 21 262 (W) 5064 cloudy dust 02:00 35 25 25 266 (W) 4947 cloudy dust 03:00 33 21 16 256 (WSW) mstly cldy dust 04:00 30 14 31 280 (W) 10666 mstly clr dust 05:00 28 10 25 282 (WNW) 14948 clear dust Note: the wind was coming from the azimuth listed.
