We had yet more amazingly clear skies! Seeing was great until around 3am when the winds shifted and seeing became poor. But, other than that, it was a great night! Bonus: arctic didn't drop a quad after the init yesterday. ------- 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 -------------------------------------------------------------------------- 19:04 dcamera 746( 1243) 86 61 14.1 15.5 15.1 14.8 14.2 -- 1.12 19:58 dcamera 630( 1078) 118 84 14.2 14.6 14.9 14.4 14.3 -- 0.98 23:23 dcamera 559( 950) -81 50 13.2 13.1 13.6 13.1 13.1 -- 1.40 00:22 arctic 549( 1117) 275 31 12.6 12.7 13.2 12.6 12.6 sdss-z 0.85 03:48 arctic 488( 1025) 108 32 12.8 12.0 12.7 11.9 12.2 sdss-z 1.78 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 61 21 8 268 (W) 874 clear none 17:00 63 22 14 243 (WSW) 1375 clear none 18:00 59 26 7 267 (W) 2605 clear none 19:00 58 26 15 260 (W) 3029 clear none 20:00 58 25 19 253 (WSW) 2778 clear none 21:00 57 24 19 261 (W) 2490 clear none 22:00 57 23 13 269 (W) 2308 clear none 23:00 56 23 15 301 (WNW) 2166 clear none 00:00 56 22 13 321 (NW) 2489 clear none 01:00 55 21 18 329 (NNW) 2104 clear none 02:00 56 22 12 9 (N) 2082 clear none 03:00 55 19 10 15 (NNE) 1333 clear none 04:00 55 17 1 207 (SSW) 1243 clear none 05:00 53 17 12 357 (N) 1354 clear none 06:00 53 15 16 9 (N) 1093 clear none Note: the wind was coming from the azimuth listed.
