Logging out and restarting TUI fixed the issue both times. For some reason we lost tracking (drift in Alt) on echelle slitviewer image 1605 - 1608 (1609 I recentered). No idea for the slip but at least it was during a readout. It tracked fine after I re-centered the star. No problems for 2nd half. ------- 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 -------------------------------------------------------------------------- 18:51 ecamera 396( -3) 157 54 13.6 15.9 15.6 15.0 13.9 clear 0.90 01:05 arctic 454( 926) 135 52 13.0 10.9 11.6 10.8 11.5 J-C_I 1.19 01:06 NA2gdr 2588(36588) 136 52 13.1 11.0 11.6 10.9 11.8 R 1.61 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 62 18 11 306 (NW) 868 clear none 17:00 63 20 6 255 (WSW) 828 clear none 18:00 58 16 3 341 (NNW) 662 clear none 19:00 57 14 6 325 (NW) 701 clear none 20:00 57 13 4 258 (WSW) 643 clear none 21:00 55 12 4 192 (SSW) 554 clear none 22:00 54 12 7 192 (SSW) 537 clear none 23:00 53 12 7 201 (SSW) 814 clear none 00:00 53 11 6 252 (WSW) 852 clear none 01:00 52 11 5 244 (WSW) 832 clear none 02:00 56 14 5 256 (WSW) 849 clear none 03:00 56 15 7 261 (W) 594 clear none 04:00 56 13 6 262 (W) 642 clear none 05:00 55 14 8 263 (W) 638 clear none 06:00 55 14 6 256 (WSW) 857 clear none Note: the wind was coming from the azimuth listed.
