A nubs restart and expose init didn't solve the issue. I vnced into the nicfps machine and there was a socket error (10054, 'connection reset by peer'). I closed the software and relaunched and everything was good. There was high dust at the beginning of the night that kept us closed for a little over an hour. Once we opened, the seeing was beautiful! There were clouds but they stuck to the eastern horizon and weren't an issue for either program. ------- 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 -------------------------------------------------------------------------- 20:03 ecamera 283( 322) -76 43 14.9 15.4 16.2 15.5 14.7 ND3 0.96 22:48 ecamera 366( 288) 0 77 14.4 13.4 14.2 13.3 13.5 clear 0.83 00:15 ecamera 362( 279) -173 59 14.0 13.1 13.8 12.8 13.4 clear 1.01 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 66 17 19 269 (W) 2137 clear none 17:00 69 17 22 216 (SW) 1708 clear none 18:00 65 15 19 262 (W) 1628 clear none 19:00 63 13 16 263 (W) 4619 clear dust 20:00 58 8 16 257 (WSW) 5296 clear dust 21:00 59 6 19 264 (W) 2874 mstly clr none 22:00 58 6 14 259 (W) 2143 mstly clr none 23:00 58 7 17 250 (WSW) 1647 mstly clr none 00:00 58 6 14 272 (W) 1543 mstly clr none 01:00 57 5 12 273 (W) 1505 mstly clr none 02:00 57 5 13 270 (W) 1595 mstly clr none 03:00 55 4 13 270 (W) 1515 mstly clr none 04:00 55 3 14 280 (W) 1544 mstly clr none 05:00 53 1 18 283 (WNW) 1618 mstly clr none Note: the wind was coming from the azimuth listed.
