We had a few clouds left before sunset but they cleared up and we had photometric skies for most of the night, though the seeing was pretty bad at first. Set KOSMOS camfoc=3070 for about -5C During checkout I had to reset the mirror covers & restarted dataq pmss program because it was frozen. A few bits of snow fell from the dome doors when I opened so I did a few test slews in azimuth before opening the mirror covers, but nothing else came off. There was one alt motion error 1:15 at about 75 alt, slewing down from 80 in the west. Telescope is parked at 80 alt. ------- 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 -------------------------------------------------------------------------- 19:01 ecamera 700( -420) 193 75 -3.8 -1.4 2.4 -2.4 -3.5 ND3 3.14 19:42 ecamera 664( -489) 217 72 -3.4 -2.1 -0.8 -3.3 -3.3 Clear 2.25 20:41 ecamera 548( -673) 234 65 -3.7 -3.6 -2.3 -3.6 -3.5 Clear 1.82 23:00 klow 476( 307) -150 53 -2.8 -3.6 -3.1 -3.5 -3.1 -- 1.80 01:23 ecamera 401( -828) 73 54 -3.2 -3.9 -3.3 -3.7 -3.8 ND3 0.87 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 24 22 25 307 (NW) mstly cldy humid 17:00 25 19 23 311 (NW) mstly clr humid 18:00 26 19 12 293 (WNW) mstly clr humid 19:00 25 17 2 320 (NW) clear humid 20:00 26 11 4 305 (NW) 395 clear none 21:00 26 11 3 344 (NNW) 665 clear none 22:00 26 9 20 2 (N) 718 clear none 23:00 27 10 20 350 (N) 2333 clear none 00:00 26 11 6 349 (N) 324 clear none 01:00 26 11 6 4 (N) 286 clear none 02:00 27 10 16 345 (NNW) 329 clear none 03:00 27 10 14 351 (N) 306 clear none 04:00 26 11 16 359 (N) 293 clear none 05:00 30 6 16 354 (N) 223 clear none 06:00 31 4 17 12 (NNE) 212 clear none Note: the wind was coming from the azimuth listed.
