Zeroed the NA2 and TR2 rotators Ecam focus done and mask updated fro echelle Agile inst block, rotator testing, and disk testing done. Agile is still having trouble tracking rotation. See Engineering email for more details. Agile rotator cotterpin fell off its cable and disappeared into telescope pit. We need a new one asap. Apollo ILE louvers propped open. Lots of intermittent radar through the night kept us closed. Candace was going to use dawn to look at Venus, but radar kept us closed. Gave up just before 6am. ------- 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 -------------------------------------------------------------------------- 03:17 AGILE 250(-1091) 149 62 10.7 10.4 10.8 10.4 10.3 SDSS_r 1.70 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 58 20 24 221 (SW) 2588 mstly cldy none 17:00 56 16 17 233 (SW) 2940 mstly cldy none 18:00 60 18 20 225 (SW) 2877 mstly cldy none 19:00 57 16 18 210 (SSW) 2431 mstly cldy none 20:00 52 20 14 196 (SSW) 2496 mstly clr none 21:00 52 20 11 206 (SSW) 2770 mstly clr none 22:00 52 18 14 213 (SSW) 2548 mstly clr none 23:00 53 19 11 211 (SSW) 2360 ptly cldy none 00:00 53 20 11 210 (SSW) 2091 mstly cldy none 01:00 52 20 6 203 (SSW) 1812 mstly cldy none 02:00 51 19 7 224 (SW) 1794 mstly cldy none 03:00 51 19 5 218 (SW) 1806 mstly clr none 04:00 51 20 6 200 (SSW) 2231 mstly clr none 05:00 50 20 1 175 (S) 2381 mstly clr none Note: the wind was coming from the azimuth listed.
