The clear skies persisted until some light clouds moved through during B half. NICFPS behaved for most of the night, but required several expose inits in the last hour of observing. gcam also wanted some attention tonight; it required a >hub startNubs at checkout, at least three more during A half, and another at the start of B half. Otherwise, the night was pretty uneventful. ------- 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 -------------------------------------------------------------------------- 19:54 arctic 510( 479) -16 49 -1.0 0.2 0.7 -0.2 -0.8 UNM657/3 1.47 20:26 arctic 456( 405) -28 47 -1.1 -0.2 0.2 -0.7 -0.9 UNM657/3 1.83 21:29 arctic 459( 391) -59 43 -0.4 -0.7 -0.2 -0.9 -0.6 CU_SII 1.38 22:19 NICFPS 344( 788) -57 30 -0.4 -0.6 -0.2 -0.6 -0.4 H2-2.12 1.53 23:44 NICFPS 385( 743) 135 66 -2.3 -1.9 -1.6 -2.3 -2.4 H2-2.12 0.74 01:21 arctic 515( 370) 67 57 -2.1 -2.1 -1.9 -2.5 -2.0 SDSS_r 1.30 05:26 tcamera 418( 478) -139 56 -2.3 -2.0 -1.9 -2.3 -2.1 Ks 1.08 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 33 8 18 276 (W) 31668 mstly cldy dust 17:00 35 8 30 278 (W) 5072 ptly cldy dust 18:00 33 5 14 267 (W) 3447 mstly clr dust 19:00 32 6 4 287 (WNW) 1554 clear none 20:00 30 8 9 352 (N) 1454 clear none 21:00 31 9 14 314 (NW) 1444 clear none 22:00 31 8 15 306 (NW) 1416 clear none 23:00 28 8 14 270 (W) 1512 clear none 00:00 28 8 14 291 (WNW) 990 clear none 01:00 29 8 17 294 (WNW) 917 clear none 02:00 29 8 16 304 (NW) 1048 mstly clr none 03:00 29 8 9 269 (W) 1098 mstly clr none 04:00 28 9 7 261 (W) 1002 mstly clr none 05:00 28 8 10 270 (W) 836 mstly clr none 06:00 28 7 14 278 (W) 710 mstly clr none Note: the wind was coming from the azimuth listed.
