We had 100% cloud cover at the start of the night. By about 19:30 we could see a few stars through the thinner clouds and decided to open up to try to get some brighter targets for NM07, but closed again at 20:30 when the clouds got thicker. We opened again just before 22:00 when the clouds finally started moving east of us. At the start of the UW02 observing program during focusing we were unable to change filters and could not home the filter wheel, so we were late getting started (see email for troubleshooting details). The reset of the night went smoothly! ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- UW02 ARCTIC I/H 01:46 02:10 ARCTIC filter wheel stuck ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:46 ecamera 380( -6) 237 55 10.0 9.8 9.9 9.8 9.8 Clear 1.04 21:58 ecamera 362( -37) 237 29 9.8 9.1 9.4 9.1 9.3 ND2 1.08 00:10 tcamera 421( 1207) 45 55 8.5 8.1 8.8 8.1 8.2 Ks 1.02 02:15 arctic 405( 1012) -58 34 8.1 7.2 7.8 7.0 7.3 SDSS_g 1.15 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 50 24 11 227 (SW) 871 cloudy none 17:00 50 20 14 211 (SSW) 561 cloudy none 18:00 49 24 12 214 (SW) 920 cloudy none 19:00 48 25 9 235 (SW) 917 cloudy none 20:00 51 17 14 266 (W) 427 cloudy none 21:00 49 19 14 271 (W) 550 ptly cldy none 22:00 50 18 11 263 (W) 446 mstly clr none 23:00 49 20 10 258 (WSW) 655 clear none 00:00 48 22 10 261 (W) 692 clear none 01:00 46 23 8 277 (W) 775 clear none 02:00 46 21 12 328 (NNW) 681 clear none 03:00 47 21 13 313 (NW) 671 clear none 04:00 46 21 10 309 (NW) 774 clear none 05:00 46 18 0 332 (NNW) 530 clear none 06:00 46 8 1 58 (ENE) 176 clear none Note: the wind was coming from the azimuth listed.
