My observer last exposure was around 18:31 but we stayed open, not seeing much in the guider. They finally gave up at 19:00 and I switched to the next program. We were able to observe UW06's targets with the echelle, even through the clouds, although bright ones helped matters. I forgot to take an echelle IOL at the start of the night so I took one when my observer finished at midnight. The clouds cleared out around 03:00. No problems tonight. ------- 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 -------------------------------------------------------------------------- 17:59 tcamera 568( 923) 122 80 10.0 3.5 2.7 3.4 2.2 Ks 1.22 19:12 ecamera 558( -464) 29 79 10.0 0.8 1.6 0.8 0.5 ND1 0.91 21:33 ecamera 423( -623) 8 56 10.0 0.0 0.7 0.0 0.3 Clear 1.11 00:05 tcamera 390( 576) -87 71 10.0 -0.2 0.3 -0.4 -0.6 Ks 1.06 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 5 199 (SSW) 751 ptly cldy none 17:00 5 185 (S) 766 mstly cldy none 18:00 10 183 (S) 228 cloudy none 19:00 7 183 (S) 753 cloudy none 20:00 11 166 (SSE) 586 cloudy none 21:00 13 179 (S) 447 mstly cldy none 22:00 14 179 (S) 396 ptly cldy none 23:00 8 178 (S) 409 ptly cldy none 00:00 6 185 (S) 490 ptly cldy none 01:00 12 233 (SW) 206 cloudy none 02:00 7 258 (WSW) 310 cloudy none 03:00 10 278 (W) 296 mstly clr none 04:00 7 270 (W) 346 clear none 05:00 8 316 (NW) 371 clear none 06:00 6 262 (W) 373 clear none Note: the wind was coming from the azimuth listed.
