Wind picked up a few hours later. Max wind gusts around 40mph, max 1-micon dust counts around 16,000 cts. We were unable to open tonight. Engineering tasks completed: - tron/tcc restarts - axis controllers restarted, NA2 rotator zeroed (-0.075) - DIS contamination checks - some scheduling work and documentation Gave up for the night around 04:00 due to continuing high dust. ------- 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 65 23 10 255 (WSW) 1203 ptly cldy none 17:00 65 24 13 259 (W) 1105 ptly cldy none 18:00 59 24 1 324 (NW) 1062 ptly cldy none 19:00 57 22 7 113 (ESE) 1129 ptly cldy none 20:00 56 22 13 86 (E) 1518 ptly cldy none 21:00 55 21 17 87 (E) 1385 ptly cldy none 22:00 54 22 16 92 (E) 1560 ptly cldy none 23:00 49 28 25 68 (ENE) 7932 mstly clr none 00:00 46 30 26 60 (ENE) 13454 clear dust 01:00 43 30 34 73 (ENE) 16024 clear dust 02:00 43 30 28 73 (ENE) 10436 clear dust 03:00 43 30 21 88 (E) 9099 ptly cldy dust 04:00 43 30 22 82 (E) 7783 ptly cldy dust Note: the wind was coming from the azimuth listed.
