We didn't open. When I tried to test the 1.25-ctr KOSMOS slit adjustment KOSMOS stopped responding and none of the normal troubleshooting methods worked (PR 2206). ------- 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 63 52 23 128 (SE) 214 ptly cldy none 17:00 60 52 21 100 (E) 157 ptly cldy none 18:00 58 52 22 87 (E) 266 ptly cldy none 19:00 58 52 22 87 (E) 217 ptly cldy none 20:00 56 53 25 112 (ESE) mstly cldy humid 21:00 55 53 21 111 (ESE) cloudy humid 22:00 54 51 20 100 (E) cloudy humid 23:00 55 51 21 115 (ESE) cloudy humid 00:00 55 52 20 113 (ESE) mstly cldy humid 01:00 55 52 21 112 (ESE) cloudy humid 02:00 56 51 21 100 (E) cloudy humid 03:00 55 51 22 117 (ESE) cloudy rain 04:00 55 51 18 113 (ESE) cloudy rain 05:00 54 53 18 135 (SE) cloudy humid Note: the wind was coming from the azimuth listed.
