Once that cleared, we got open for a few hours, but dealt with thicker clouds. Humidity spiked up again, just before twilight. Had problems with the DIS turret, PR submitted. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:31 dcamera 299( 635) 215 77 8.8 13.5 13.2 13.4 10.1 -- 2.00 20:26 dcamera 250( 406) 198 58 7.0 9.8 10.2 9.3 7.4 -- 3.20 01:57 dcamera 343( 350) 261 36 6.4 6.2 7.3 6.3 6.0 -- 2.60 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp C Dewp C MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 60 12 11 195 (SSW) 1009 clear none 17:00 64 17 7 225 (SW) 1056 mstly clr none 18:00 62 16 17 233 (SW) 1124 mstly clr none 19:00 58 10 17 250 (WSW) 1494 mstly clr none 20:00 50 35 11 85 (E) 775 mstly clr none 21:00 46 38 16 85 (E) 699 mstly clr humid 22:00 44 39 15 82 (E) 849 mstly clr humid 23:00 43 40 13 80 (E) 1209 clear humid 00:00 43 40 12 91 (E) 1711 clear humid 01:00 42 40 13 87 (E) 1570 clear humid 02:00 42 39 13 90 (E) 1051 clear humid 03:00 44 37 18 123 (ESE) 1264 ptly cldy none 04:00 45 37 24 123 (ESE) 1425 mstly cldy none 05:00 44 41 14 109 (ESE) 1510 mstly cldy humid Note: the wind was coming from the azimuth listed.
