Small puffy clouds began to move through before midnight, and gradually thickened. We closed shortly after 04:00 due to heavy clouds, increasing humidity, and approaching radar echoes. Everything worked very nicely. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEGDFNVO) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 20:25 SPIcam 200(1422) 129 58 5.2/6.1 109 9 I 1.33 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 54 30 1 251 (WSW) 1577 ptly cldy none 17:01 57 32 0 101 (E) 1218 mstly clr none 18:01 50 30 11 148 (SSE) 1362 clear none 19:01 46 30 12 113 (ESE) 1417 clear none 20:01 42 29 17 122 (ESE) 1412 clear none 21:01 40 28 7 97 (E) 1243 clear none 22:01 41 28 16 125 (SE) 1427 mstly clr none 23:01 42 30 18 139 (SE) 1189 ptly cldy none 00:01 44 30 16 136 (SE) 1140 mstly clr none 01:01 43 30 17 149 (SSE) 1388 ptly cldy none 02:01 42 31 15 177 (S) 1449 ptly cldy none 03:01 42 32 17 163 (SSE) 1421 ptly cldy none 04:01 43 33 18 152 (SSE) 1411 mstly cldy none 05:01 44 36 5 188 (S) 1443 cloudy none Note: the wind was coming from the azimuth listed.
