Russet had to restart the APOLLO ICC at the start of the night and we were unable to use ACS. We also found some new errors with atui on obsA! But otherwise things went smoothly. Fiducial error in az at the end of the night (13:50:29). ------- 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 -------------------------------------------------------------------------- 17:21 ecamera 544( -98) 246 50 0.1 1.1 1.4 0.9 0.9 ND3 1.04 00:16 ecamera 300( -491) -156 59 -1.3 -1.9 -2.1 -3.1 -2.3 ND2 1.09 06:01 APOLLO 325( 1232) -65 52 -4.2 -3.8 -3.2 -3.8 -3.2 530 1.70 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 35 11 2 250 (WSW) 262 ptly cldy none 17:00 34 9 6 93 (E) 186 ptly cldy none 18:00 32 8 11 52 (NE) 225 ptly cldy none 19:00 35 1 7 48 (NE) 62 ptly cldy none 20:00 30 6 16 65 (ENE) 203 ptly cldy none 21:00 28 11 18 66 (ENE) 286 mstly clr none 22:00 27 12 14 77 (ENE) 305 clear none 23:00 28 8 5 13 (NNE) 294 clear none 00:00 28 3 6 348 (NNW) 157 clear none 01:00 29 4 8 348 (NNW) 142 clear none 02:00 27 6 3 12 (NNE) 165 clear none 03:00 27 6 6 2 (N) 214 clear none 04:00 25 11 10 6 (N) 302 clear none 05:00 27 8 6 6 (N) 230 clear none 06:00 26 6 6 3 (N) 210 clear none Note: the wind was coming from the azimuth listed.
