I tried axis stop/init, but slew failed 2nd time. I then tried a small slew in the TCC, which worked, then a little larger one, which worked, and then the full slew, which now worked. I also found the rotator off by about -0.3 degrees when I when to do the instrument change from NICFPS to DIS. I noticed NICFPS was rotated slightly on the cart when I mounted it for first half but just thought somebody managed to rotate the instrument while unmounting it last night. Apparently not. I will re-zero the rotator during checkout tommorow afternoon, unless we have guiding issues tonight. DIS was left on for moring cals The rotator was at 0 when I went to do morning fills. Not sure why it didn't go to zero for NICFPS when I rotated it earlier. Maybe the crart rotated the instrument when I went to take it off the rotator. ------- 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 -------------------------------------------------------------------------- 20:06 NICFPS 501( 1808) 184 71 21.1 21.8 22.2 21.4 20.9 H 1.20 21:48 NICFPS 412( 1653) 98 37 19.7 20.1 20.7 19.7 19.8 H 1.10 23:11 NICFPS 437( 1637) 112 52 20.2 19.5 20.2 19.4 19.5 FeII-1.64 0.90 00:27 dcamera 337( 996) 99 47 19.2 18.6 19.3 18.5 18.6 -- 1.60 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 80 35 13 257 (WSW) 782 clear none 17:00 79 33 12 244 (WSW) 626 clear none 18:00 77 34 17 226 (SW) 664 clear none 19:00 76 32 22 254 (WSW) 682 clear none 20:00 72 28 19 266 (W) 601 clear none 21:00 71 23 18 240 (WSW) 559 clear none 22:00 68 24 15 248 (WSW) 689 clear none 23:00 69 24 16 265 (W) 822 clear none 00:00 69 23 10 267 (W) 612 clear none 01:00 66 22 9 256 (WSW) 505 clear none 02:00 65 22 6 258 (WSW) 536 clear none 03:00 66 21 5 294 (WNW) 510 clear none 04:00 66 22 6 6 (N) 623 clear none 05:00 65 21 6 24 (NNE) 553 clear none Note: the wind was coming from the azimuth listed.
