The radar returns were showing up just crossing the county line to our west and the system seemed to be moving this direction, as well as disappating once the sun went down. So it was a wait and see game until the radar returns got a little further away from us. The LANL team was using the closed time for laser alignment. I cleaned the bird poo off the Omea all sky camera tonight. We opened around 22:05 as the storm passed to our SW and the clouds subsided. Humidity closed us at 00:00 and we re-opened at 00:45. No problems tonight. ------- 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 -------------------------------------------------------------------------- 22:31 ecamera 542( 151) 171 80 11.6 14.2 13.8 13.8 12.0 ND2 0.69 23:03 ecamera 479( 49) 203 79 11.7 13.3 13.2 12.9 11.9 ND2 0.76 23:31 ecamera 476( 5) 221 70 11.5 12.5 12.8 12.2 11.5 ND2 1.00 00:56 ecamera 433( -47) 254 50 12.8 12.0 12.7 11.6 12.2 ND2 0.76 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 58 30 7 238 (WSW) 1018 cloudy lt rain 17:00 60 30 11 225 (SW) 1004 cloudy none 18:00 63 30 9 232 (SW) 1061 mstly cldy none 19:00 54 30 2 252 (WSW) 1427 mstly cldy none 20:00 53 30 1 322 (NW) 1653 ptly cldy none 21:00 53 30 6 332 (NNW) 894 ptly cldy none 22:00 53 29 7 305 (NW) 1200 mstly clr none 23:00 53 30 6 275 (W) 1413 mstly clr humid 00:00 53 29 2 261 (W) mstly clr none 01:00 55 31 5 279 (W) 801 mstly clr none 02:00 54 32 6 266 (W) 1090 ptly cldy none 03:00 54 31 4 267 (W) 844 mstly clr none 04:00 52 31 6 274 (W) 948 ptly cldy humid 05:00 52 31 2 309 (NW) 1302 mstly clr none 06:00 53 31 6 327 (NNW) 549 mstly clr none Note: the wind was coming from the azimuth listed.
