UT05:31 0-104 deg, Az 20 Alt drive ringing while slewing to park position. Axis stop did not stop ringing, after slew finished but stop button did. Clouds all night but little if any precip. Lots of radar returns around us. ------------- FAILURE LOG -------------- PROG INST FAILURE MODE TIME (STEDFNVOG) 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 ------------------------------------------------------------------- 18:00 45 45 8 90 (E) 895 cloudy none 19:00 43 43 15 82 (E) 534 cloudy none 20:00 42 42 20 131 (SE) 441 cloudy none 21:00 43 43 20 125 (SE) 450 cloudy none 22:00 46 46 21 107 (ESE) 529 cloudy none 23:00 45 45 20 106 (ESE) 328 cloudy none 00:00 41 41 17 124 (SE) 128 cloudy none 01:00 39 39 9 140 (SE) 346 cloudy none 02:00 39 39 8 91 (E) 400 cloudy none 03:00 44 44 7 89 (E) 511 mstly cldy none Note: the wind was coming from the azimuth listed.
