More of a thin drizzle as you could barely feel it. Humidity started going up around 2am but then it was formally a light rain. Winds kicked up to nearly 40mph around 10pm but calmed down enough in B half to run slews. There was no hope in opening tonight. Keaton Bell from UW05 is on site to begin his training and observing tomorrow. However, he was a good sport and willingly participated in 7 hours of training tonight! By the time we get him on sky on Saturday, he'll be a pro! He'll be using AGILE so we ran a few test rotations and, while the AGILE rotator never freewheeled, it did experience a motion error at mount rot 120. An init solved the problem. I'll run some more rotations test tomorrow. ------- 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 43 -2 12 210 (SSW) 30 cloudy none 17:00 43 -2 7 236 (SW) 21 cloudy none 18:00 41 -2 5 178 (S) 28 cloudy none 19:00 42 1 12 138 (SE) 98 cloudy none 20:00 42 1 11 175 (S) 53 cloudy none 21:00 41 3 19 146 (SE) 163 cloudy none 22:00 40 15 18 163 (SSE) 215 cloudy lt rain 23:00 42 24 15 188 (S) 195 cloudy lt rain 00:00 38 28 27 182 (S) 222 cloudy lt rain 01:00 37 28 20 174 (S) 225 cloudy lt rain 02:00 34 31 15 166 (SSE) cloudy lt rain 03:00 37 29 14 228 (SW) 144 cloudy lt rain 04:00 37 30 12 184 (S) 124 cloudy lt rain 05:00 37 31 11 177 (S) 94 cloudy lt rain Note: the wind was coming from the azimuth listed.
