Echelle ICC needed a restart about 21:15. Clouds grew thicker through the night. It was not looking hopeful, and we almost quit around 03:00 but some helpful suckerholes came along, and we powered through till twilight. We were open all night. ------- 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 -------------------------------------------------------------------------- 17:42 arctic 346( 649) 32 54 5.8 7.3 7.4 7.2 6.0 SDSS_g 0.92 18:02 ecamera 288( -534) 24 56 5.6 6.8 7.0 6.3 5.7 ND1 0.83 18:57 ecamera 236( -645) 127 51 4.6 5.6 5.9 5.3 4.8 ND4 1.07 20:08 arctic 388( 576) 136 53 6.4 5.0 5.4 4.6 5.5 SDSS_i 1.18 00:19 dcamera 439( 524) 26 52 7.5 6.6 6.9 6.7 7.2 - 1.20 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 45 0 7 239 (WSW) 98 ptly cldy none 17:00 42 -3 6 260 (W) 27 ptly cldy none 18:00 43 -2 3 227 (SW) 14 ptly cldy none 19:00 41 -4 9 221 (SW) 25 ptly cldy none 20:00 43 -1 10 217 (SW) 38 ptly cldy none 21:00 42 -3 10 201 (SSW) 34 ptly cldy none 22:00 44 -1 9 202 (SSW) 21 ptly cldy none 23:00 45 1 9 178 (S) 33 ptly cldy none 00:00 45 1 14 186 (S) 27 ptly cldy none 01:00 46 2 14 195 (SSW) 43 ptly cldy none 02:00 47 1 16 188 (S) 30 ptly cldy none 03:00 44 0 12 183 (S) 73 ptly cldy none 04:00 42 0 14 211 (SSW) 104 ptly cldy none 05:00 45 -2 11 187 (S) 64 ptly cldy none 06:00 46 -3 21 186 (S) 46 ptly cldy none Note: the wind was coming from the azimuth listed.
