During A-half at about -5 to -7C, the KOSMOS slitviewer shutter was sticking every once in a while (not at the level of interrupting observations, and mostly right after we stopped guiding for internal cals). ARCTIC vacuum controller still unhappy; temperatures still fine. AZ did have a Fiducial Error Too Large problem on a long slew in the SE but started correcting again. ------- 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 -------------------------------------------------------------------------- 17:55 kosmos 225( 344) 6 52 -7.1 -5.0 -4.6 -5.6 -6.6 -- 3.00 19:33 klow 225( 270) -178 51 -7.4 -6.7 -6.1 -7.2 -7.2 -- 2.40 00:18 tcamera 414( 588) -17 62 -7.2 -8.0 -7.3 -8.0 -7.6 Ks 1.26 02:29 kimage 414( 411) 37 55 -5.7 -7.6 -6.9 -7.6 -6.8 -- 1.47 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 24 4 13 46 (NE) 406 clear none 17:00 22 11 11 83 (E) 312 clear none 18:00 20 11 3 84 (E) 257 clear none 19:00 19 2 5 90 (E) 305 clear none 20:00 19 1 13 62 (ENE) 236 clear none 21:00 20 -6 17 58 (ENE) 197 clear none 22:00 19 -2 15 61 (ENE) 183 clear none 23:00 19 -2 18 63 (ENE) 185 clear none 00:00 19 -2 13 65 (ENE) 198 clear none 01:00 19 -11 5 357 (N) 177 clear none 02:00 23 -14 8 345 (NNW) 170 clear none 03:00 21 -19 12 339 (NNW) 163 clear none 04:00 20 -17 15 354 (N) 170 clear none 05:00 20 -16 9 345 (NNW) 189 clear none 06:00 25 -19 9 354 (N) 187 clear none Note: the wind was coming from the azimuth listed.
