Humidity stayed too high to open even though the clouds and radar cleared up at a few points during the night. During checkout, the tertiary failed to clamp when it rotated from NA1 to NA2 and required a direct move command with talk2boxes to clamp. After this the mirror would not close without a hub startNubs telmech command. This in turn caused Tert Rot to read "?" in the Enclosure window. Russet edited the map for the NA2 position, we ran hub startNubs telmech again, and then the Enclosure window showed the correct Tert Rot and the mirror covers worked. ------- 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 52 52 16 151 (SSE) cloudy lt rain 17:00 53 51 9 138 (SE) cloudy lt rain 18:00 54 54 3 242 (WSW) mstly cldy humid 19:00 56 49 5 175 (S) ptly cldy humid 20:00 55 53 4 90 (E) ptly cldy humid 21:00 53 52 2 97 (E) ptly cldy humid 22:00 53 51 8 93 (E) mstly clr humid 23:00 52 51 10 101 (E) mstly clr humid 00:00 52 51 10 88 (E) ptly cldy humid 01:00 52 51 7 91 (E) mstly cldy humid 02:00 51 50 7 113 (ESE) mstly cldy humid 03:00 51 50 6 132 (SE) ptly cldy humid 04:00 51 50 8 124 (SE) ptly cldy humid 05:00 52 49 3 228 (SW) ptly cldy humid Note: the wind was coming from the azimuth listed.
