I tried restarting the nubs and then restarting the camera to no avail. I called Fritz to help fix it. He got it working again. Fritz determined an NFS permission problem caused the non-updating images, and then (maybe) the camera restarts made the camera unhappy. In the end he fixed the NFS problem then got the camera working again by excercising it manually. The clue to the unhappy camera was the 0 0 0 0 0 error messages in TUI. No problems after Fritz fixed the ecam slitviewer. No problems second half except for cirrus clouds moving in towards morning. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- DD02 E I/S 21:15 23:08 ecam got hung, NFS problem ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 17:10 APOLLO 650( 1294) 50 65 3.8 4.8 4.3 4.7 4.2 -- 1.20 18:13 ecamera 581( -757) -91 63 4.2 4.2 4.2 3.9 4.1 ND2 0.70 00:10 dcamera 580( 317) 200 68 6.3 4.7 5.3 4.9 5.3 -- 1.20 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp C Dewp C MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 40 6 5 339 (NNW) 21 clear none 17:00 39 5 12 303 (WNW) 31 clear none 18:00 39 8 11 300 (WNW) 19 clear none 19:00 39 6 7 267 (W) 20 clear none 20:00 38 7 7 262 (W) 0 clear none 21:00 40 6 6 260 (W) 13 clear none 22:00 40 5 11 255 (WSW) 10 clear none 23:00 40 2 11 237 (WSW) 39 clear none 00:00 43 2 13 226 (SW) 16 clear none 01:00 43 0 7 210 (SSW) 27 clear none 02:00 44 -1 10 215 (SW) 6 clear none 03:00 43 -2 14 211 (SSW) 18 mstly clr none 04:00 43 -1 14 219 (SW) 21 mstly clr none 05:00 43 0 15 205 (SSW) 22 ptly cldy none 06:00 44 3 15 203 (SSW) 156 ptly cldy none Note: the wind was coming from the azimuth listed.
