Elevated dust levels to start the second half of the night but we were able to open at the start of the second half. We had some internet connectivity issues during 2nd half. They seemed to resolve themselves. Seems to have started around Midnight and looked to resolve itself by 01:30 or so. Unfortunately It didn't help data collection for my second half observer as they were having issues adjusting focus since their computer kept having connection problems because of the internet connection issue. ------- 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 -------------------------------------------------------------------------- 01:18 AGILE -1325(-2212) 111 50 2.3 5.0 6.5 3.8 3.4 r' 2.10 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 54 11 25 284 (WNW) 21371 clear dust 17:00 56 11 20 265 (W) 26410 mstly clr dust 18:00 53 17 22 270 (W) 17158 mstly clr dust 19:00 50 6 9 329 (NNW) 20929 clear dust 20:00 47 1 9 286 (WNW) 10143 clear dust 21:00 45 0 18 322 (NW) 10032 clear dust 22:00 43 -1 13 311 (NW) 6816 clear dust 23:00 41 0 17 328 (NNW) 6079 clear dust 00:00 39 1 18 297 (WNW) 7034 clear dust 01:00 37 5 7 324 (NW) 4536 clear none 02:00 35 8 20 315 (NW) 3038 clear none 03:00 32 6 13 6 (N) 1767 clear none 04:00 32 4 21 24 (NNE) 2150 clear none 05:00 31 5 21 355 (N) 1189 clear none 06:00 30 6 22 7 (N) 990 clear none Note: the wind was coming from the azimuth listed.
