Motion error on a very short slew to a focus star at 22:20 at 60.5 alt just after setting the instrument to ARCTIC. CG01 had some trouble with ecam exposures updating and restarted, and afterwards at 06:29, was unable to start a new exposure. I was also unable to start a new exposure (the start button produced a status of “object tim... started” at the bottom of the Echelle Expose window but did not begin integrating. I did echelle init, and then hub startNubs echelle & hub startNubs echelleExpose and was able to start one final exposure. After CG01 finished observing I tried running the Echelle interorder light script and got the error “error from motor controller: '\x15[Invalid Command]\r>’””. I turned the Echelle quartz lamp off and set the cal mirror to lamps from the Echelle TUI window and was able to run the script without further problems. ------- 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 -------------------------------------------------------------------------- 18:09 ecamera 517( -248) 228 35 1.2 1.4 1.7 1.7 1.4 ND4 0.69 22:28 arctic 445( 670) 147 61 0.4 -0.5 -0.4 -0.8 -0.2 SDSS_r 0.91 04:59 ecamera 344( -515) 58 59 0.9 -0.2 0.4 -0.5 0.0 ND4 0.92 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 36 11 8 331 (NNW) 298 clear none 17:00 34 12 3 348 (NNW) 322 clear none 18:00 34 2 11 354 (N) 159 clear none 19:00 32 1 10 356 (N) 109 clear none 20:00 31 2 10 23 (NNE) 103 clear none 21:00 30 2 8 354 (N) 117 clear none 22:00 31 4 10 359 (N) 93 clear none 23:00 33 6 17 32 (NNE) 145 clear none 00:00 33 7 6 3 (N) 153 clear none 01:00 32 9 13 21 (NNE) 196 clear none 02:00 33 10 15 49 (NE) 191 clear none 03:00 35 4 6 96 (E) 75 clear none 04:00 32 6 7 92 (E) 93 clear none 05:00 34 4 10 141 (SE) 67 clear none 06:00 32 5 9 155 (SSE) 82 clear none Note: the wind was coming from the azimuth listed.
