The camera would not expose and, after many hours of trouble shooting, we were not able to solve the issue. A PR was sent (2028). We had intermittent KOSMOS slitviewer capabilities as the temperatures were a few degrees C below zero, so mostly used NA2 guider for guiding, and sometimes had to use KOSMOS imaging mode to center up targets. Skies were clear all night with seeing that improved over time. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- GS02 ECAM I/H 18:47 23:04 ecam failure, see PR 2028 GS01 KOSMOS I/U 00:15 00:45 Instrument swap delayed due to sick obs spec ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 17:49 APOLLO 700( 1441) -72 52 -6.8 -4.2 -4.4 -4.6 -6.0 530 3.00 23:05 dcamera 553( 347) -99 34 -2.2 -5.5 -4.8 -5.4 -3.9 -- 1.82 01:14 khigh 475( 420) 153 78 -4.3 -5.2 -4.7 -5.4 -4.9 -- 0.88 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 26 12 3 218 (SW) 459 clear none 17:00 22 2 7 98 (E) 156 clear none 18:00 20 -2 11 67 (ENE) 135 clear none 19:00 20 -8 16 76 (ENE) 111 clear none 20:00 20 -10 6 91 (E) 60 clear none 21:00 22 -13 6 100 (E) 59 clear none 22:00 26 -18 3 105 (ESE) 53 clear none 23:00 28 -20 2 162 (SSE) 60 clear none 00:00 25 -20 2 128 (SE) 79 clear none 01:00 24 -17 6 144 (SE) 40 clear none 02:00 24 -19 7 185 (S) 55 clear none 03:00 25 -19 6 187 (S) 75 clear none 04:00 26 -21 7 189 (S) 56 clear none 05:00 28 -24 6 187 (S) 54 clear none 06:00 29 -27 8 196 (SSW) 47 clear none Note: the wind was coming from the azimuth listed.
