It was a quick fix to get the telescope working again (basically just power cycle drives and then an axis init). Emails sent to the engineering staff with all the gory details and log dumps. ------- 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 -------------------------------------------------------------------------- 18:27 ecamera 464( -761) 166 69 -2.2 -1.4 -1.2 -1.7 -2.4 ND1 1.10 00:13 tcamera 570( 390) 7 62 -1.2 -1.6 -1.1 -1.4 -1.2 Ks 1.50 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 33 13 22 251 (WSW) 959 clear none 17:00 31 13 11 242 (WSW) 893 clear none 18:00 28 13 12 213 (SSW) 956 clear none 19:00 28 14 15 204 (SSW) 976 clear none 20:00 30 4 14 206 (SSW) 771 clear none 21:00 29 12 16 211 (SSW) 745 clear none 22:00 30 12 18 200 (SSW) 782 clear none 23:00 30 11 17 219 (SW) 742 mstly clr none 00:00 30 9 14 235 (SW) 731 mstly clr none 01:00 29 11 13 258 (WSW) 642 mstly clr none 02:00 30 11 17 249 (WSW) 556 mstly clr none 03:00 29 13 23 243 (WSW) 586 mstly clr none 04:00 30 13 18 254 (WSW) 621 mstly clr none 05:00 30 10 17 239 (WSW) 509 mstly clr none 06:00 30 5 17 218 (SW) 442 mstly clr none Note: the wind was coming from the azimuth listed.
