The problem prevented us slewing the telescope. Russet and Conor worked on getting us a temporary fix for the tonight. The issue (due to the USNO where we source the necessary files) affected the 2.5m telescope as well. 2020-02-14 00:45:36 APO.APO-Jack 75 tcc f Exception=RuntimeError; text="No earth orientation data for this TAI date" No other problems tonight (and decent pointing) once we had the temporary fix in place. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- GS04 Echelle T/S 17:55 18:45 Telescope coordinate file out of date due to USNO issue. ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 18:46 ecamera 488( -683) 68 63 -0.9 -0.4 -0.7 -0.8 -1.2 ND3 1.10 00:07 ecamera 391( -768) 149 39 0.8 -0.5 -0.0 -0.8 0.7 ND4 1.08 03:16 APOLLO 425( 1031) 47 35 0.6 -0.3 0.5 -0.5 0.2 -- 1.10 04:48 ecamera 388( -750) 132 35 0.6 -0.2 0.5 -0.2 0.8 clear 0.89 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 33 14 10 300 (WNW) 96 clear none 17:00 31 5 7 334 (NNW) 73 clear none 18:00 30 -1 10 337 (NNW) 59 clear none 19:00 30 -1 8 2 (N) 69 clear none 20:00 30 6 5 8 (N) 73 clear none 21:00 32 -1 11 15 (NNE) 82 clear none 22:00 31 -1 7 345 (NNW) 56 clear none 23:00 33 -1 10 355 (N) 53 clear none 00:00 34 -4 6 354 (N) 38 clear none 01:00 33 -6 5 346 (NNW) 23 clear none 02:00 35 -6 6 300 (WNW) 28 clear none 03:00 34 -5 2 217 (SW) 16 clear none 04:00 33 -5 1 217 (SW) 41 clear none 05:00 32 -7 7 191 (S) 29 mstly clr none 06:00 32 -9 7 189 (S) 45 mstly clr none Note: the wind was coming from the azimuth listed.
