We remained closed, but ran the snow program all of first half. Second Half Observing Specialist: R.McMillan Clouds and fog cleared off around midnight. Humidity remained high until after 0400. Snow remained on the dome all night. The wind was too light to make much progress in blowing it off. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEGDFVO) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- --------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 17:01 15 13 13 325 (NW) 11 Prtly Cldy None 18:01 15 14 14 315 (NW) 69 Prtly Cldy None 19:01 15 14 12 306 (NW) 5178 Prtly Cldy None 20:01 16 15 8 324 (NW) 2526 Prtly Cldy None 21:01 17 15 2 352 (N) 9646 Clear None 22:01 17 15 8 348 (NNW) 310 Clear None 23:01 16 14 16 357 (N) 14 Clear None 00:01 16 14 9 35 (NE) 26 mstly clr none 01:01 16 14 12 338 (NNW) 34 mstly clr none 02:01 16 14 15 343 (NNW) 41 mstly clr none 03:01 16 14 15 336 (NNW) 39 mstly clr none 04:01 16 13 14 350 (N) 37 mstly clr none 05:01 16 9 15 332 (NNW) 35 mstly clr none Note: the wind was coming from the azimuth listed.
