Observer reported the following error while running a cal script. We had to change the cal mirror stange manually in TUI, and that seemed to work. "Failed: echelle mirror sky failed: error from motor controller: '\x15[Invalid Command]\r>' Arcsat weather/rain interlock was triggered, even though the weather cleared up and we were able to open. It may be worth having someone check the arcsat rain sensor to make sure it's working properly. It may be worth checking the arcsat humidity sensor too. Other than the arcsat weather problem, the night was pretty low-key! ------- 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 -------------------------------------------------------------------------- 20:40 ecamera 249( 194) -26 59 12.7 13.7 13.7 13.7 12.8 ND1 0.97 21:34 ecamera 275( 184) -39 54 13.1 12.9 13.1 12.6 12.6 clear 1.15 01:23 arctic 262( 1185) 338 51 10.7 10.9 11.6 10.6 10.7 BG40 1.30 02:56 arctic 304( 1217) 309 40 11.4 10.6 11.1 10.3 11.0 BG40 1.03 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 57 42 1 199 (SSW) 816 cloudy rain 17:00 56 36 9 49 (NE) 549 cloudy lt rain 18:00 58 38 1 206 (SSW) 751 cloudy none 19:00 56 29 8 203 (SSW) 484 mstly cldy none 20:00 56 27 13 144 (SE) 632 ptly cldy none 21:00 54 25 10 148 (SSE) 873 mstly clr none 22:00 56 24 11 151 (SSE) 758 clear none 23:00 55 25 12 151 (SSE) 768 clear none 00:00 54 27 5 137 (SE) 1018 clear none 01:00 52 32 8 138 (SE) 931 clear none 02:00 52 32 10 171 (S) 852 clear none 03:00 52 33 9 179 (S) 866 clear none 04:00 50 33 8 188 (S) 656 clear none 05:00 50 33 5 201 (SSW) 599 clear none 06:00 52 33 5 238 (WSW) 592 clear none Note: the wind was coming from the azimuth listed.
