We had one motion error due south at 60 right after reinitializing the axes in alt, commanded a slew and the telescope didn't move in alt, we just got a motion error, but no other problems with the telescope. I restarted TUI on the dome mac because it was lagging, but I did not restart the computer. NM01 finished up on sky a few minutes early and donated the rest of their time to OU02. For ARCSAT I had to restart ACP a few times due to the script hanging when an exposure finished, but none of the other programs on the ARCSAT computer had any trouble. ------- 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 -------------------------------------------------------------------------- 18:41 tcamera 510( 1836) 143 55 13.7 16.4 15.5 16.3 14.6 Ks 0.81 19:47 arctic 350( 1460) 62 32 13.5 14.6 14.5 14.2 13.5 J-C_Ic 1.05 23:52 ecamera 299( 154) -19 53 12.1 11.7 12.2 11.6 11.8 ND4 0.96 01:02 khigh 272( 1178) 168 43 12.5 11.6 12.2 11.4 11.9 -- 1.14 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 60 28 11 325 (NW) 1618 mstly clr none 17:00 60 28 8 338 (NNW) 2024 mstly clr none 18:00 58 28 4 267 (W) 1468 mstly clr none 19:00 57 27 4 342 (NNW) 1395 ptly cldy none 20:00 56 27 11 295 (WNW) 1542 ptly cldy none 21:00 53 28 7 256 (WSW) 1384 mstly clr none 22:00 55 32 10 238 (WSW) 1666 ptly cldy none 23:00 54 34 6 254 (WSW) 1643 ptly cldy none 00:00 54 34 10 296 (WNW) 1465 mstly clr none 01:00 55 34 10 273 (W) 1547 mstly clr none 02:00 55 34 9 287 (WNW) 1241 clear none 03:00 54 34 11 318 (NW) 1311 clear none 04:00 53 33 7 333 (NNW) 1184 clear none 05:00 52 33 9 323 (NW) 1179 clear none 06:00 52 28 3 339 (NNW) 1221 clear none Note: the wind was coming from the azimuth listed.
