Dembicky Clouds and dust prevented opening and cooling during sunset. The dust subsided shortly after sunset but the clouds stuck around until around 1:30. I opened the enclosure at 01:30 but by 2:10 clouds were moving back overhead and the sky remained variable thru the remainder of the night. At 05:00 the GrIm ICC crashed and needed to be rebooted, only lost about 2 mins during twilight. ------- FAILURE LOG ------- PROG INST FAILURE TIME S/E/G/D/O TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- UC03 G I/S --:-- --:-- GrIm ICC crashed, rebooted ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 01:47 GrIm-f/5 -110(683) 72 53 10.8/11.5 280 12 H 0.79 01:52 NA2gdr -754(59245) 72 53 11.0/11.4 269 16 R 0.97 03:52 GrIm-f/5 110(935) 97 30 9.4/9.9 270 13 H 1.08 --------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 63 33 23 199 (SSW) 442 Cloudy none 17:01 60 33 18 202 (SSW) 390 Cloudy Lt.
