Winds really started picking up at switch over and I had to close the dome while mounting arctic just in case it gusted too high. But it came back down and we were able to continue. 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 -------------------------------------------------------------------------- 18:22 dcamera 528( 334) 205 65 -0.4 0.8 0.8 1.0 -0.1 -- 1.23 21:59 dcamera 526( 289) 281 36 0.6 -0.6 0.1 -0.2 0.6 -- 1.58 05:07 arctic 473( 444) -60 60 0.8 0.4 1.1 0.6 0.7 sdss-i 1.20 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 35 -5 12 3 (N) 555 clear none 17:00 32 6 1 79 (E) 719 clear none 18:00 32 -13 8 356 (N) 303 clear none 19:00 30 -15 22 19 (NNE) 167 clear none 20:00 31 -14 17 12 (NNE) 163 clear none 21:00 31 -14 18 21 (NNE) 159 clear none 22:00 33 -13 22 31 (NNE) 85 clear none 23:00 32 -18 16 5 (N) 160 clear none 00:00 29 -8 26 21 (NNE) 311 clear none 01:00 32 -12 21 26 (NNE) 250 clear none 02:00 35 -15 22 29 (NNE) 96 clear none 03:00 36 -10 9 5 (N) 130 clear none 04:00 35 -11 15 23 (NNE) 91 clear none 05:00 33 -13 16 31 (NNE) 119 clear none 06:00 34 -11 10 345 (NNW) 127 clear none Note: the wind was coming from the azimuth listed.
