As per wiki instructions, I restarted the nubs for NICFPS and issued "nicfps expose init", which resolved the problem and allowed nicfps to take exposures again. Windy, dusty, and cloudy during the afternoon; the wind and clouds persisted into the evening. We tried to open around 19:15, but the clouds were too thick to even focus the telescope, and WY02 gave up around 19:30. For UW06, we were able to focus on a bright star, but didn't have any luck acquiring any of the targets for long enough to get any science; the clouds were pretty thick and forming over us continuously. UV01 was only able to get some data after the clouds began to thin out, about 05:45 AM. Note that tonight was MST -> MDT switchover night; actual elapsed time for UV01 was 6 hours, not 7. ------- 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 -------------------------------------------------------------------------- 20:07 ecamera 518( -277) 50 83 10.0 5.6 6.3 5.4 5.1 ND2 1.41 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 23 270 (W) 2506 mstly cldy dust 17:00 29 271 (W) 2161 mstly cldy dust 18:00 28 268 (W) 1891 mstly cldy none 19:00 22 270 (W) 1512 cloudy none 20:00 19 275 (W) 1429 cloudy none 21:00 16 266 (W) 1411 cloudy none 22:00 24 264 (W) 934 cloudy none 23:00 21 280 (W) 1017 cloudy none 00:00 19 270 (W) 1301 cloudy none 01:00 18 278 (W) 1333 cloudy none 03:00 11 272 (W) 1576 cloudy none 04:00 8 265 (W) 1562 cloudy none 05:00 10 280 (W) 1506 cloudy none 06:00 7 351 (N) 1230 mstly cldy none Note: the wind was coming from the azimuth listed.
