However, seeing was good for A half and the BYU class was able to get a lot of good data in the IR! The clouds became thicker around 3am and UW02 gave up at 03:40am. WY02 was mostly able to punch through. When I went to save the night log I was given the error that it could not save because I don't have permission. I emailed Gordon and Shane but am sending this night log via manual email, so hopefully there are no issues... ------- 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 -------------------------------------------------------------------------- 17:42 NICFPS 273( 1560) 179 46 7.0 10.2 9.4 10.9 7.8 MK-J 0.99 19:10 NICFPS 383( 1585) 188 67 10.3 8.6 8.9 8.2 9.2 MK-J 1.08 23:07 tcamera 365( 1315) 214 52 9.5 8.4 9.0 8.2 8.8 Ks 1.25 01:47 kosmos 274( 990) -38 50 8.7 7.6 8.2 7.5 7.9 -- 1.53 04:37 tcamera 308( 1214) -70 37 7.8 7.3 7.8 7.3 7.5 -- 1.94 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 49 35 2 197 (SSW) 656 ptly cldy none 17:00 49 22 1 208 (SSW) 470 ptly cldy none 18:00 46 25 6 353 (N) 535 ptly cldy none 19:00 50 1 2 236 (SW) 607 ptly cldy none 20:00 52 -8 5 236 (SW) 292 ptly cldy none 21:00 49 -14 4 235 (SW) 192 ptly cldy none 22:00 49 -13 5 203 (SSW) 216 ptly cldy none 23:00 47 -11 8 257 (WSW) 102 ptly cldy none 00:00 48 -7 7 278 (W) 95 ptly cldy none 01:00 47 -4 6 255 (WSW) 72 mstly cldy none 02:00 49 -7 8 232 (SW) 65 mstly cldy none 03:00 47 -4 9 256 (WSW) 59 cloudy none 04:00 46 16 8 258 (WSW) 161 mstly cldy none 05:00 46 24 14 258 (WSW) 273 mstly cldy none 06:00 45 29 12 265 (W) 352 mstly cldy none Note: the wind was coming from the azimuth listed.
