Thanks Jack! Thick clouds rolled in around 9pm, and we closed up just after 10pm. Reopened at midnight. Clouds were a persistant pest throughout rest of the night. Closed for the night at 5:50am. Problems initializing the support library on arcsat happened again. Check LN2 tank #10. It seemed like it was leaking all night even though I closed it. ------- 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 -------------------------------------------------------------------------- 17:23 dssi 300( 1455) -4 71 8.7 9.8 10.1 9.5 9.0 -- 1.40 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 51 10 24 218 (SW) 1017 clear none 17:00 48 9 18 204 (SSW) 1259 clear none 18:00 48 9 20 207 (SSW) 1943 clear dust 19:00 49 8 26 192 (SSW) 3236 mstly clr dust 20:00 49 7 26 208 (SSW) 3674 ptly cldy dust 21:00 48 7 22 199 (SSW) 3136 cloudy none 22:00 47 5 20 193 (SSW) 2776 cloudy none 23:00 47 4 22 214 (SW) 1389 cloudy none 00:00 45 3 24 236 (SW) 1337 ptly cldy none 01:00 45 2 16 222 (SW) 818 ptly cldy none 02:00 44 1 15 227 (SW) 988 ptly cldy none 03:00 42 0 22 219 (SW) 626 mstly cldy none 04:00 43 2 19 240 (WSW) 560 cloudy none 05:00 43 2 19 218 (SW) 515 cloudy none Note: the wind was coming from the azimuth listed.
