We homed the mirror and manually set the tert to the NA1 port with ABC values for the actuators. The C actuator was the problem. Thank you Bill for the help. .tcc.0 0 tcc w Text="Collimation Failure: Cancelled while queued by new command '758 move -2000.0000,80.0000,590.0000,0.0000,-2000.0000'" Apollo is down and that hour was donated to BY01. Another collimation failure at 23:15 after set inst was done. But the mirror status looked fine and it didn't repeat so we stayed on sky. 2024-09-26 05:16:10 .tcc.0 0 tcc w Text="Collimation Failure: Cancelled while queued by new command '758 move -2000.0000,80.0000,590.0000,0.0000,-2000.0000'" ------- 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 -------------------------------------------------------------------------- 20:23 ecamera 373(326) 176 78 12.6 14.1 14.4 13.2 13.1 clear 1.11 21:25 ecamera 321(219) 219 74 12.1 12.9 13.4 12.3 12.5 clear 1.45 23:50 kosmos 215( 1135) -93 63 13.2 12.2 12.7 12.0 12.6 -- 1.55 03:50 tcamera 315( 1436) 209 47 13.2 11.9 12.6 11.8 12.4 -- 1.15 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 63 38 8 188 (S) 773 clear none 17:00 64 39 11 204 (SSW) 730 clear none 18:00 64 40 5 192 (SSW) 790 clear none 19:00 58 39 9 207 (SSW) 758 clear none 20:00 55 40 9 90 (E) 800 clear none 21:00 54 41 10 96 (E) 868 clear none 22:00 54 41 10 86 (E) 870 clear none 23:00 55 40 11 92 (E) 832 clear none 00:00 56 37 11 76 (ENE) 708 clear none 01:00 53 36 5 7 (N) 744 clear none 02:00 57 38 2 24 (NNE) 869 clear none 03:00 53 38 3 353 (N) 838 clear none 04:00 56 39 6 347 (NNW) 753 clear none 05:00 56 38 3 328 (NNW) 772 clear none 06:00 54 39 2 241 (WSW) 849 clear none Note: the wind was coming from the azimuth listed.
