Seeing wasn't very good at the start of the night but improved over time. Set KOSMOS camfoc=3070 for T=-5C and focused in imaging mode. The KOSMOS slitviewer did not work very well in the colder temperatures tonight and we had to use imaging mode to help acquire some of the targets and NA2 guider to guide. During checkout and again at 23:03, got the error "the target named gcam is not connected” and had to do hub startNubs gcam + gcam init to bring it back both times. A little after 01:00 KOSMOS finished reading out an image but got stuck at "writing" for over a few minutes. The lost image was rescued and I restarted kosmos-icc and reset the heater deadband. OU02 handed over to CG01 a few minutes early as they only had internal cals left. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- OU02 KOSMOS I/S 01:09 01:24 KOSMOS stuck at "writing" and had to restart kosmos-icc ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:06 kosmos 185( 316) -53 73 -3.0 -1.4 -1.0 -2.2 -2.3 -- 1.99 02:43 kosmos 285( 279) 36 65 -2.8 -4.3 -3.7 -4.3 -3.9 -- 1.22 04:31 ecamera 442( -592) 44 63 -2.8 -3.9 -3.4 -3.8 -3.6 ND4 1.12 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 30 -2 29 280 (W) 3110 clear none 17:00 31 -2 27 282 (WNW) 2920 clear none 18:00 28 -3 14 266 (W) 1876 clear none 19:00 27 -2 14 279 (W) 1450 clear none 20:00 26 0 14 294 (WNW) 1427 clear none 21:00 25 1 5 265 (W) 1349 clear none 22:00 25 0 1 346 (NNW) 1028 clear none 23:00 26 2 9 346 (NNW) 848 clear none 00:00 24 3 12 350 (N) 864 clear none 01:00 27 1 11 272 (W) 1005 clear none 02:00 27 0 8 263 (W) 858 clear none 03:00 27 -1 7 263 (W) 636 clear none 04:00 27 -2 8 274 (W) 377 clear none 05:00 27 -2 8 262 (W) 374 clear none 06:00 26 -1 8 191 (S) 527 clear none Note: the wind was coming from the azimuth listed.
