The night started with thunderstorms to the north and we delayed opening for about an hour. However, we were then only open about an hour as new radar popped up. it started raining around 23:30 and, after it stopped, the pollen was high and I stayed closed. Things died down around 4am and NM06 was able to get some photons with moderate-good seeing all night. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:11 dcamera 572( 1167) 92 48 13.5 15.4 15.3 15.4 13.6 -- 1.21 03:17 ecamera 479( 18) 124 61 11.3 11.5 11.8 11.6 11.2 ND1 0.85 04:18 APOLLO 500( 1780) 56 33 10.8 10.9 11.3 10.8 10.8 530 1.10 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 64 34 25 208 (SSW) 345 ptly cldy none 17:00 63 30 19 199 (SSW) 388 ptly cldy none 18:00 61 25 20 247 (WSW) 431 ptly cldy none 19:00 58 26 29 225 (SW) 447 ptly cldy none 20:00 56 23 16 226 (SW) 464 mstly cldy none 21:00 56 21 19 210 (SSW) 427 mstly cldy none 22:00 55 22 15 234 (SW) 579 mstly cldy none 23:00 56 23 15 238 (WSW) 664 mstly cldy lt rain 00:00 55 22 16 232 (SW) 664 mstly cldy none 01:00 54 24 12 184 (S) 1468 mstly cldy none 02:00 53 25 9 216 (SW) 3646 ptly cldy none 03:00 53 25 10 229 (SW) 3581 ptly cldy none 04:00 53 23 6 266 (W) 2494 mstly clr none 05:00 53 24 11 305 (NW) 1752 mstly clr none 06:00 49 25 8 346 (NNW) 1499 mstly clr none Note: the wind was coming from the azimuth listed.
