Clouds all afternoon, with some rain. Around sunset the clouds thinned, but I could see virga to the south, a big thunderhead formed just east of us, and some fog not far away, the outside humidity was too high and the satellite showed stuff heading our way from the north but also falling apart too. Oh, and radar returns north of us near the county border. I opted to stay closed, due to the high humidity. Clouds, humidity and a few sprinkles off and on during the entire night kept us closed. We gave up at 04:00 with little hope of opening. We had an issue with the DIS blue ion pump/controller and it not sending alerts. Shane rebooted the machine and Bill also found the HD full. Once they fixed those issues things worked normally and the controller/pump was happy again. ------- 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 57 30 17 49 (NE) ptly cldy none 17:00 61 30 9 83 (E) 369 ptly cldy none 18:00 62 31 6 69 (ENE) 364 ptly cldy none 19:00 64 31 5 196 (SSW) 370 cloudy none 20:00 58 31 5 33 (NNE) ptly cldy humid 21:00 57 31 18 76 (ENE) ptly cldy lt rain 22:00 56 30 18 75 (ENE) ptly cldy humid 23:00 56 31 19 72 (ENE) mstly cldy humid 00:00 54 30 8 350 (N) mstly cldy humid 01:00 54 31 14 81 (E) cloudy humid 02:00 56 30 4 351 (N) cloudy humid 03:00 53 30 2 328 (NNW) cloudy lt rain 04:00 52 30 8 110 (ESE) cloudy humid Note: the wind was coming from the azimuth listed.
