There were a few wisps of clouds so we didn't have the photometric sky necessary for throughput measurements, but it was nice and clear! The gcam filter menu needed to be woken up with gmech parameters, and stripchart mac froze (spiked cpu processing) and I had to restart it. Engineering tasks: - KOSMOS focus tests - Pointing Model - NA2 Guider shutter tested along with pointing model - Tracking Check - More testing new versions of TUI We did see a few instances of Fiducial Errors too large on az slews, but the telescope had no problems. Dome is parked south. ------- 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 -------------------------------------------------------------------------- 17:41 kosmos 137( 438) 105 62 -3.3 -1.0 -1.6 -1.6 -2.6 -- 1.63 18:39 kosmos 200( 457) 105 74 -3.1 -1.8 -2.5 -3.1 -3.2 -- 1.09 18:51 kosmos 113( 363) 106 76 -2.9 -2.0 -2.6 -3.2 -3.3 -- 1.35 00:26 tcamera 410( 800) -7 63 -2.5 -3.4 -2.7 -3.2 -2.9 Ks 1.09 02:17 arctic 407( 667) 86 44 -2.4 -3.2 -2.8 -3.2 -3.0 ARCTIC_3500 2.34 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 29 13 13 299 (WNW) 236 mstly clr none 17:00 26 13 15 335 (NNW) 395 clear none 18:00 27 12 6 281 (W) 239 clear none 19:00 27 14 9 312 (NW) 196 clear none 20:00 26 12 9 300 (WNW) 216 clear none 21:00 26 13 12 321 (NW) 200 clear none 22:00 27 15 12 327 (NNW) 248 clear none 23:00 29 14 14 299 (WNW) 238 clear none 00:00 27 18 17 303 (WNW) 300 clear none 01:00 28 16 16 283 (WNW) 258 clear none 02:00 27 17 15 312 (NW) 292 clear none 03:00 28 14 11 328 (NNW) 256 clear none 04:00 28 13 5 346 (NNW) 310 clear none 05:00 26 15 8 0 (N) 350 clear none 06:00 26 15 12 337 (NNW) 440 clear none Note: the wind was coming from the azimuth listed.
