The night started out with clouds and humidity, but we were still able to open and stay open for a few hours. However, around 9:30 pm, the humidity was getting too high and I could see fog on the cloud cam and we closed. Luckily, we were able to reopen at 2am! And, while the wind didn't shift, the humidity plummeted around 4am and we were able to stay open until twilight. ------- 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 -------------------------------------------------------------------------- 18:06 klow 313( 797) 140 51 2.0 3.1 3.0 3.0 2.3 -- 0.67 02:06 kosmos 335( 675) 90 68 1.8 0.5 1.2 1.0 1.2 -- 0.95 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 38 28 9 269 (W) ptly cldy none 17:00 36 28 11 268 (W) ptly cldy none 18:00 36 28 11 278 (W) ptly cldy none 19:00 36 27 13 302 (WNW) mstly cldy none 20:00 36 27 15 312 (NW) mstly cldy none 21:00 35 28 9 306 (NW) mstly cldy none 22:00 34 28 14 314 (NW) mstly cldy humid 23:00 34 28 7 309 (NW) mstly cldy humid 00:00 34 28 10 332 (NNW) cloudy humid 01:00 36 26 17 352 (N) ptly cldy humid 02:00 35 25 22 6 (N) 450 mstly cldy humid 03:00 36 18 13 15 (NNE) 1237 ptly cldy humid 04:00 36 16 18 5 (N) 207 ptly cldy none 05:00 37 1 19 8 (N) 140 ptly cldy none 06:00 38 -15 28 23 (NNE) 85 ptly cldy none Note: the wind was coming from the azimuth listed.
