Although Agile checked out this afternoon, the rotator failed at ~120 degrees in mount coordinates. We followed the object without rotation tracking until 22:10, when we could pause the exposures. I inspected for physical impairments, and found nothing. I stopped and started the axes, and ran Agile through a few more slews in a talk2boxes session. That seemed to clear it up. Slewed back to target, and began tracking as normal at 22:30. No more problems with 3.5-m. See email for 0.5-m. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- UW04 Agile I/H 22:10 22:30 Agile rotator failed in tracking. ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:33 dcamera 393( 1268) 17 82 21.3 24.0 23.6 22.9 22.0 -- 1.48 21:29 AGILE 443( -822) 170 74 21.2 22.3 22.4 21.6 21.0 BG40 1.77 01:43 ecamera 666( 269) 122 65 19.8 19.6 20.2 19.5 19.4 ND2 0.90 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 81 41 18 239 (WSW) 919 clear none 17:00 82 38 9 256 (WSW) 738 clear none 18:00 79 39 12 222 (SW) 682 clear none 19:00 76 36 12 215 (SW) 735 clear none 20:00 72 31 4 205 (SSW) 652 clear none 21:00 71 30 8 224 (SW) 690 clear none 22:00 69 29 7 283 (WNW) 990 clear none 23:00 68 29 6 308 (NW) 905 clear none 00:00 68 29 7 344 (NNW) 949 clear none 01:00 68 29 1 343 (NNW) 1029 clear none 02:00 67 27 6 348 (NNW) 1044 clear none 03:00 66 27 5 20 (NNE) 1043 clear none 04:00 65 25 7 124 (SE) 1052 clear none 05:00 65 25 5 183 (S) 1262 clear none Note: the wind was coming from the azimuth listed.
