I inverted the instrument and moved the diffuser in place, which seemed to help. First half ended a little early and gave their remaining time to WY03. They finished their transit observations and collected all the data that they needed. 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 -------------------------------------------------------------------------- 20:02 arctic 672( 1117) 120 52 8.9 10.3 10.2 10.0 9.0 SDSS_I 1.64 20:05 NA2gdr 1001(35001) 120 53 8.9 10.2 10.1 9.8 8.9 clear 2.00 01:15 ecamera 412( -457) 238 63 6.6 6.0 6.7 5.8 6.4 ND2 1.05 03:17 dcamera 538( 571) 239 41 5.7 5.3 6.0 5.4 5.5 -- 1.43 04:41 dcamera 428( 396) 9 46 3.8 4.0 4.7 3.8 3.8 -- 1.30 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 55 6 19 269 (W) 3697 clear none 17:00 56 10 23 251 (WSW) 2021 clear none 18:00 53 6 25 266 (W) 2722 clear none 19:00 50 3 19 276 (W) 2775 clear none 20:00 48 -1 25 278 (W) 1979 clear none 21:00 47 0 24 277 (W) 1691 clear none 22:00 46 1 17 295 (WNW) 1313 clear none 23:00 46 2 13 297 (WNW) 1436 clear none 00:00 44 0 10 312 (NW) 1524 clear none 01:00 44 0 9 358 (N) 1660 clear none 02:00 43 -1 3 342 (NNW) 2106 clear none 03:00 42 -1 8 327 (NNW) 2380 clear none 04:00 39 -3 6 342 (NNW) 2846 clear none 05:00 39 -1 6 344 (NNW) 2910 clear none 06:00 39 1 6 333 (NNW) 3353 clear none Note: the wind was coming from the azimuth listed.
