Eventually some high clouds moved in, and seeing degraded after 02:00, but all told it was a very nice night with lots of data. Everything worked perfectly during the night, though we had a scare when aiscam froze up and jeppe rebooted right at sunset. ------- 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 --------------------------------------------------------------------- 20:35 gfp -50(1381) 258 36 7.8/8.9 266 5 R 0.82 20:35 NA2gdr 2161(27161) 258 36 7.8/8.8 265 5 R 0.89 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 49 27 12 357 (N) 562 ptly cldy none 17:01 49 28 8 333 (NNW) 596 ptly cldy none 18:01 49 30 3 282 (WNW) 557 mstly clr none 19:01 48 30 4 281 (W) 574 mstly clr none 20:01 46 30 6 295 (WNW) 615 clear none 21:01 45 30 5 264 (W) 587 clear none 22:01 46 30 8 245 (WSW) 759 mstly clr none 23:01 45 29 3 184 (S) 764 mstly clr none 00:01 45 29 5 177 (S) 794 mstly clr none 01:01 46 27 5 181 (S) 821 cirrus none 02:01 44 27 4 106 (ESE) 865 cirrus none 03:01 45 27 6 148 (SSE) 878 cirrus none 04:01 44 26 6 148 (SSE) 873 cirrus none 05:01 45 25 6 172 (S) 952 cirrus none 06:01 44 27 10 142 (SE) 806 cirrus none Note: the wind was coming from the azimuth listed.
