We also relaxed the primary mirror, reset the optical cloudcam, and went over methods for collimating the telescope, including the Shack-Hartmann instrument. ------- 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 -------------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 65 50 15 252 (WSW) 950 ptly cldy none 17:00 65 51 6 233 (SW) 1044 ptly cldy none 18:00 61 49 11 222 (SW) 1105 mstly cldy lt rain 19:00 60 50 10 231 (SW) 878 cloudy lt rain 20:00 59 50 3 211 (SSW) 861 cloudy none 21:00 58 49 9 124 (SE) 962 cloudy none 22:00 59 47 14 136 (SE) 807 cloudy none 23:00 59 47 14 142 (SE) 733 cloudy lt rain 00:00 54 51 18 132 (SE) cloudy none 01:00 53 47 20 131 (SE) cloudy none 02:00 54 47 14 119 (ESE) 593 cloudy none 03:00 56 46 15 151 (SSE) 426 cloudy none 04:00 56 44 9 182 (S) 387 cloudy none Note: the wind was coming from the azimuth listed.
