I did a fill time dump during each as well. We had random thin passing clouds for most of the night. No telescope issues 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 -------------------------------------------------------------------------- 18:13 tcamera 560( 1387) 99 49 3.0 5.7 5.0 5.8 3.9 Ks 1.25 19:44 tcamera 435( 1136) -27 60 2.8 3.2 3.5 2.8 2.9 Ks 1.00 22:56 dssi 350( 1097) 10 72 2.2 1.1 2.4 1.6 1.9 692nm 0.60 00:09 dssi 370( 1145) -3 29 2.1 1.1 2.2 1.4 2.0 692nm 1.60 05:06 dssi 365( 1083) 183 68 0.8 0.5 1.4 0.5 0.8 692nm 0.50 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 40 14 7 6 (N) 175 clear none 17:00 39 13 10 353 (N) 218 clear none 18:00 38 14 20 23 (NNE) 279 clear none 19:00 37 15 16 18 (NNE) 188 mstly clr none 20:00 37 17 7 355 (N) 142 mstly clr none 21:00 37 18 13 23 (NNE) 180 mstly clr none 22:00 35 18 8 21 (NNE) 173 mstly clr none 23:00 36 17 14 39 (NE) 182 mstly clr none 00:00 36 17 11 83 (E) 181 mstly clr none 01:00 36 17 7 90 (E) 160 mstly clr none 02:00 36 16 5 84 (E) 173 mstly clr none 03:00 36 18 4 185 (S) 207 mstly clr none 04:00 35 18 4 140 (SE) 252 mstly clr none 05:00 34 18 7 138 (SE) 236 mstly clr none 06:00 34 18 4 152 (SSE) 223 mstly clr none Note: the wind was coming from the azimuth listed.
