CU07 paused observing between 18:40 and 19:20 due to thicker clouds, but we stayed open during this time as conditions were not dangerous. At the end of the night I closed the dome a few minutes early due to radar but CU03 had enough twilight flats for their observations. No telescope or instrument problems. ------- 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 -------------------------------------------------------------------------- 17:19 NICFPS 446( 1386) 237 58 5.7 6.1 6.2 6.0 5.8 H2-2.12 0.61 17:50 NA2gdr 6999(49999) 238 53 5.4 5.6 5.9 5.4 5.4 Clear 1.10 20:01 NICFPS 356( 1230) 210 48 5.4 4.6 5.2 4.6 5.0 H2-2.12 0.63 21:23 ecamera 401( -209) 44 40 5.4 4.8 5.4 4.9 5.2 ND1 1.07 22:55 tcamera 401( 1022) -1 63 5.7 4.7 5.4 5.0 5.1 Ks 1.08 00:22 arctic 380( 901) 83 23 5.7 5.0 5.5 5.2 5.6 ARCTIC_4170 2.01 01:44 arctic 369( 865) 69 40 5.4 4.9 5.5 5.0 5.1 ARCTIC_4170 1.17 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 44 14 14 15 (NNE) 115 mstly clr none 17:00 42 14 12 1 (N) 115 mstly clr none 18:00 41 14 6 348 (NNW) 145 ptly cldy none 19:00 41 13 8 343 (NNW) 256 mstly cldy none 20:00 42 15 8 267 (W) 138 ptly cldy none 21:00 43 14 12 291 (WNW) 184 mstly clr none 22:00 42 13 12 304 (NW) 199 mstly clr none 23:00 43 14 13 314 (NW) 116 mstly clr none 00:00 43 17 11 269 (W) 143 mstly clr none 01:00 43 15 19 288 (WNW) 128 mstly clr none 02:00 43 8 14 266 (W) 117 mstly clr none 03:00 42 -1 15 275 (W) 95 mstly clr none 04:00 43 0 18 273 (W) 160 mstly clr none 05:00 43 2 23 273 (W) 252 ptly cldy none 06:00 43 5 21 276 (W) 323 ptly cldy none Note: the wind was coming from the azimuth listed.
