Restarted the icc and that seemed to fix it. Reset mirror covers and the all sky cam software. Thank you Jack and Amanda and Bill for the remote support tonight! Reset kosmos collfoc, as it was showing up blank. Kcam looked like the shutter wasn't working, but after working with Jack and Amanda on it, we decided that wasn't the cause. See PR 2235. BY03 donated about 20 minutes of time to NM08. NM08 donated about 20 minutes to BY01. A half was eventful with kcam not acting right, but the rest of the night was calm. We had clouds in B half, but we were able to observe well enough through them. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- BY03 KOSMOS I/H 17:37 19:50 kcam not taking images properly, see PR#2235 ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 18:16 khigh 521( 972) 66 71 3.1 3.3 2.8 3.3 2.9 -- 0.82 20:27 kimage 346( 859) -169 58 5.0 3.4 3.7 3.4 4.3 -- 0.85 00:17 ecamera 333( -223) 178 59 3.1 3.0 3.6 3.2 3.0 clear 0.75 05:37 tcamera 331( 940) 131 52 2.2 1.1 2.2 1.8 2.0 -- 1.71 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 38 -13 15 277 (W) 109 mstly clr none 17:00 37 -14 10 265 (W) 132 mstly clr none 18:00 38 -14 16 272 (W) 144 mstly clr none 19:00 38 -13 13 275 (W) 130 ptly cldy none 20:00 40 -11 15 272 (W) 173 ptly cldy none 21:00 40 -13 14 274 (W) 179 ptly cldy none 22:00 39 -13 11 251 (WSW) 196 ptly cldy none 23:00 39 -12 15 241 (WSW) 170 ptly cldy none 00:00 38 -12 9 241 (WSW) 147 ptly cldy none 01:00 37 -15 8 236 (SW) 197 ptly cldy none 02:00 37 -15 17 225 (SW) 358 ptly cldy none 03:00 36 -14 16 265 (W) 735 mstly cldy none 04:00 36 -5 8 260 (W) 790 mstly cldy none 05:00 36 9 12 264 (W) 808 mstly cldy none 06:00 36 9 15 286 (WNW) 782 mstly cldy none Note: the wind was coming from the azimuth listed.
