They donated the rest of their time to WY01, but WY01 couldn't shoot through the clouds either, and we closed at 21:30. A spot of slightly clearer skies came through around 23:00 and we opened for a bit to get some data. We closed up again at 01:01, then opened up again at 03:00 and stayed open until clouds came back around 05:45. ------- 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 -------------------------------------------------------------------------- 17:28 arctic 318( 1086) 258 60 6.3 7.8 7.7 7.5 6.4 Semrock 1.26 20:49 ecamera 367( -51) 278 33 6.4 5.5 6.1 5.5 5.6 Clear 1.46 23:15 ecamera 427( -8) 283 44 6.2 5.4 5.9 5.4 5.9 Clear 0.89 00:24 arctic 376( 1007) 79 70 4.6 5.0 5.6 5.1 4.8 CU_VR 1.24 03:15 arctic 340( 956) 270 61 5.1 4.6 5.1 4.6 4.8 CU_VR 1.05 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 47 1 13 187 (S) 101 mstly cldy none 17:00 43 -7 14 205 (SSW) 67 ptly cldy none 18:00 43 -3 16 195 (SSW) 77 mstly cldy none 19:00 43 -5 11 186 (S) 62 cloudy none 20:00 43 -7 8 183 (S) 93 cloudy none 21:00 42 -5 8 181 (S) 176 cloudy none 22:00 42 -7 6 196 (SSW) 184 cloudy none 23:00 43 -3 13 226 (SW) 450 mstly cldy none 00:00 43 4 10 192 (SSW) 605 mstly cldy none 01:00 41 2 12 172 (S) 327 cloudy none 02:00 42 -5 12 196 (SSW) 231 mstly cldy none 03:00 40 4 12 183 (S) 374 mstly clr none 04:00 42 -5 11 226 (SW) 253 mstly clr none 05:00 42 -5 4 214 (SW) 295 mstly clr none Note: the wind was coming from the azimuth listed.
