There was a tertiary failure on the first move of the night during check out as I moved from NA2 to NA1. After NA1 failed to lock in place I moved to BC1 then back to NA1 and didn't have any further issues. When I went to field with DIS we found the star was half a FOV away from the slit in the Alt direction. I had the UW09 keep Guide (switch to Calib) offsets and they continued to observe without any time lost. At dawn, I cleared the Calib offsets and slewed to a bright star and found the pointing was off by half the FOV of gcam in the alt direction. We then moved to the echelle and found that the target was centered. Moving back to DIS, we found the target was not as far off center as it was previously. Russet suggests that is not a true pointing issue but a tertiary rotation leading to pointing issue in NA2. Russet sent an email to Bill with the details. I was busy all of A half with ARCSAT. First with the camera not exposing requiring a power coord reboot and then the field wouldn't plate solve. This eventually turned into a double runaway which was eventually solved. The pointing was still off but the field was visible. At that point, at that point, I couldn't stay away from the 3.5m any longer. Even though we had lots of problems tonight, no time was lost. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 17:13 ecamera 785( -412) 252 67 -4.5 -0.8 -1.2 -0.6 -3.8 ND3 1.11 18:28 dcamera 680( 231) 2 52 -3.7 -3.0 -2.9 -3.3 -3.6 -- 1.89 00:08 dcamera 654( 231) 176 70 -2.2 -2.3 -2.4 -2.7 -2.3 -- 1.95 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 27 10 6 276 (W) 122 mstly cldy none 17:00 24 11 4 336 (NNW) 113 clear none 18:00 24 9 8 308 (NW) 235 clear none 19:00 27 8 11 302 (WNW) 167 clear none 20:00 27 11 7 281 (W) 182 clear none 21:00 25 17 9 273 (W) 268 clear none 22:00 25 17 9 265 (W) 241 clear none 23:00 28 3 15 291 (WNW) 133 clear none 00:00 28 16 14 327 (NNW) 274 clear none 01:00 28 10 13 344 (NNW) 146 clear none 02:00 27 11 8 309 (NW) 179 clear none 03:00 27 15 7 302 (WNW) 224 clear none 04:00 26 15 12 307 (NW) 251 clear none 05:00 28 8 10 275 (W) 164 clear none 06:00 30 7 14 310 (NW) 85 clear none Note: the wind was coming from the azimuth listed.
