We had clear skies, with only thin clouds in the last 3 hours, and good seeing! There was an altitude oscillation around 23:55 that last about 3 min (az=206, alt=60, I sent out an email) but, other than that, things were easy-peasy. ------- 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 -------------------------------------------------------------------------- 18:16 ecamera 269( -406) 198 81 8.1 10.3 9.6 9.2 8.5 Clear 0.89 21:54 ecamera 325( -439) 228 42 8.7 7.9 8.6 7.4 8.2 Clear 0.97 23:17 ecamera 369( -403) 226 29 8.6 7.5 8.2 7.2 8.3 Clear 0.98 00:14 APOLLO 400( 1347) 76 50 8.3 7.2 7.9 7.0 7.4 530 1.50 01:16 ecamera 408( -397) 166 65 7.8 7.4 8.0 7.5 7.7 ND1 0.71 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 56 32 9 251 (WSW) clear none 17:00 52 29 8 244 (WSW) clear none 18:00 51 29 6 255 (WSW) clear none 19:00 45 25 1 205 (SSW) clear none 20:00 49 12 0 282 (WNW) clear none 21:00 48 10 0 6 (N) clear none 22:00 48 12 2 337 (NNW) clear none 23:00 48 12 0 241 (WSW) clear none 00:00 47 12 1 149 (SSE) clear none 01:00 47 21 6 167 (SSE) clear none 02:00 46 21 11 154 (SSE) clear none 03:00 45 13 5 195 (SSW) ptly cldy none 04:00 45 7 8 183 (S) mstly clr none 05:00 45 18 6 215 (SW) mstly clr none 06:00 44 24 3 244 (WSW) mstly clr none Note: the wind was coming from the azimuth listed.
