With the nice photometric sky, we did a lot of throughput measurements. Tasks accomplished: - Restarted hub (from trunk for KOSMOS) and tcc - Reset axis controllers - Zeroed Agile rotator - replaced foam plug in the TR1 hole, as it had fallen out - Checked pointing at various altitudes with ARCTIC - Adjusted pointing for TR2/agile, NA1/echelle, BC1/apollo, and TR4/shack - Adjusted focus zeropoint - Got a few potential APOLLO sag measurements - Throughput with ARCTIC, plus more throughput with ARCTIC - Shack-Hartmann altitude sweep More altitude motion errors tonight: - 57.1 deg slewing downward in NE - 62.8 deg slewing downward in SE - 43.1 deg slewing downward in SW ------- 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 -------------------------------------------------------------------------- 20:56 ecamera 260( 189) 38 74 15.9 16.7 16.9 16.4 15.9 ND3 0.66 22:50 arctic 204( 1152) -67 47 14.6 14.6 15.3 14.4 14.3 SDSS_r 0.95 03:05 arctic 385( 1080) 36 52 14.4 13.6 14.2 13.5 13.9 SDSS_r 0.94 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 70 51 2 228 (SW) 1201 ptly cldy none 17:00 64 47 3 163 (SSE) 1324 ptly cldy none 18:00 66 44 2 226 (SW) 1158 ptly cldy none 19:00 63 42 8 134 (SE) 1109 ptly cldy none 20:00 62 39 8 110 (ESE) 1112 mstly clr none 21:00 61 38 11 84 (E) 1135 clear none 22:00 59 42 12 103 (ESE) 1264 clear none 23:00 58 43 14 113 (ESE) 1324 clear none 00:00 59 42 13 86 (E) 1378 clear none 01:00 58 41 11 87 (E) 1265 clear none 02:00 58 41 12 86 (E) 1259 clear none 03:00 58 43 12 87 (E) 1234 clear none 04:00 58 42 10 88 (E) 1252 clear none 05:00 58 42 6 95 (E) 1249 clear none 06:00 57 43 2 195 (SSW) 1258 mstly clr none Note: the wind was coming from the azimuth listed.
