See was excellent all night. However, clouds started rolling in near down due to a storm from the south and, as it was getting too bright for UW08's target, we closed at 12deg twilight. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:50 NICFPS 543( 1646) 38 42 16.2 17.4 17.8 17.3 16.9 MK-H 0.85 21:40 NICFPS 578( 1608) 27 58 16.3 16.2 16.8 16.3 16.4 MK-H 0.63 23:48 NICFPS 502( 1485) 136 70 15.5 15.4 15.9 15.2 15.1 MK-H 0.90 00:29 dcamera 465( 948) 74 52 16.2 15.2 15.8 15.0 15.1 -- 1.11 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 57 48 10 29 (NNE) 521 ptly cldy none 17:00 61 50 2 260 (W) 629 ptly cldy none 18:00 66 48 6 207 (SSW) 671 mstly clr none 19:00 64 45 10 197 (SSW) 750 mstly clr none 20:00 62 45 12 167 (SSE) 882 mstly clr none 21:00 61 45 11 161 (SSE) 870 clear none 22:00 61 45 9 167 (SSE) 829 clear none 23:00 61 43 7 173 (S) 760 clear none 00:00 61 44 5 236 (SW) 769 clear none 01:00 60 46 1 222 (SW) 825 mstly clr none 02:00 61 46 1 29 (NNE) 833 clear none 03:00 60 45 3 352 (N) 807 clear none 04:00 61 45 1 87 (E) 895 mstly clr none 05:00 60 44 1 116 (ESE) 852 ptly cldy none Note: the wind was coming from the azimuth listed.
