Seeing was much better tonight!! The only issue we had was when the ARCTIC filter wheel needed to be homed while upside down. The filters had become lost and it took some time to get the instrument right-side up and then back on field. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- UW01 R I/H 02:00 02:100 lost filter wheel ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:48 dcamera 688( 838) 9 76 10.0 7.0 6.7 7.8 4.1 -- 1.51 20:45 ecamera 457( -401) 70 79 10.0 4.2 4.7 4.0 2.3 ND2 1.38 23:11 arctic 482( 610) 35 66 10.0 1.7 3.4 2.5 3.1 sdss-i 1.04 03:18 ecamera 393( -582) 121 40 10.0 1.2 2.5 1.7 2.1 Clear 1.77 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 4 289 (WNW) 2941 mstly clr none 17:00 15 252 (WSW) 2628 mstly clr none 18:00 10 235 (SW) 2426 mstly clr none 19:00 8 55 (NE) 2375 mstly clr none 20:00 14 71 (ENE) 2540 mstly clr none 21:00 11 77 (ENE) 2574 mstly clr none 22:00 2 105 (ESE) 2611 clear none 23:00 7 96 (E) 2744 clear none 00:00 9 186 (S) 2942 clear none 01:00 3 191 (S) 2748 clear none 02:00 8 148 (SSE) 3284 clear none 03:00 3 196 (SSW) 3243 clear none 04:00 5 173 (S) 3189 clear none 05:00 2 192 (SSW) 2854 clear none 06:00 3 208 (SSW) 2433 mstly clr none Note: the wind was coming from the azimuth listed.
