The stripchart mac froze so I restarted it. I took some KOSMOS bias image sequences and ARCTIC shutter tests exposures as it got colder in the dome. We got some snow at 00:30, with maybe a quarter of an inch accumulated on the sidewalk, which stopped falling by 02:00. Started snow program at 01:00, stopped at 05:00. Dome is parked south in case anything is still stuck to it, but it was pretty windy. ------- 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 -------------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 21 14 16 260 (W) 323 mstly cldy none 17:00 20 14 20 251 (WSW) 388 mstly cldy none 18:00 17 15 17 271 (W) cloudy humid 19:00 16 16 21 251 (WSW) cloudy humid 20:00 15 16 20 265 (W) cloudy humid 21:00 15 15 23 295 (WNW) cloudy humid 22:00 14 16 19 279 (W) cloudy humid 23:00 14 16 19 293 (WNW) cloudy humid 00:00 14 17 16 301 (WNW) cloudy snow 01:00 14 16 22 306 (NW) cloudy snow 02:00 12 14 11 18 (NNE) cloudy humid 03:00 11 13 8 331 (NNW) cloudy humid 04:00 11 12 13 1 (N) mstly clr humid 05:00 10 12 15 336 (NNW) mstly clr humid Note: the wind was coming from the azimuth listed.
