We had clear skies, excellent seeing for almost all of the night, and, while the winds were gusting to 30, it didn't bother observations a jont. WY02 reached a point where they couldn't get another nod set in so they donated 24 min to NM08. The moths are getting thick, but no problems tonight. ------- 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 -------------------------------------------------------------------------- 17:44 ecamera 754( 653) 223 47 14.7 15.7 14.3 15.5 14.8 ND1 0.74 18:43 ecamera 595( 418) 224 39 13.4 13.9 13.9 13.6 13.1 ND1 0.73 21:09 ecamera 437( 186) 203 59 13.9 12.7 13.3 12.8 13.1 ND1 1.32 23:04 ecamera 414( 131) 75 70 12.4 12.2 12.8 12.2 12.4 ND1 0.82 00:14 tcamera 458( 1432) 59 46 12.4 12.0 12.6 12.0 12.1 Ks 1.09 01:22 ecamera 425( 109) 53 73 11.6 11.5 12.1 11.4 11.6 ND2 0.82 05:14 dcamera 376( 827) 82 50 8.6 8.8 9.5 8.6 8.6 -- 1.42 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 64 32 10 209 (SSW) 795 clear none 17:00 62 25 11 185 (S) 767 clear none 18:00 60 22 11 190 (S) 677 clear none 19:00 59 8 12 183 (S) 322 clear none 20:00 56 27 19 187 (S) 1973 clear none 21:00 56 27 21 190 (S) 1894 clear none 22:00 57 21 18 204 (SSW) 1358 clear none 23:00 56 22 20 207 (SSW) 1154 clear none 00:00 56 21 22 213 (SSW) 949 clear none 01:00 55 25 24 212 (SSW) 1373 clear none 02:00 54 25 25 199 (SSW) 1194 clear none 03:00 53 25 26 209 (SSW) 938 clear none 04:00 51 24 22 212 (SSW) 884 clear none 05:00 49 25 19 234 (SW) 864 clear none 06:00 49 26 15 248 (WSW) 845 clear none Note: the wind was coming from the azimuth listed.
