Started off with some in-dome focusing KOSMOS from 17:00-18:00, on-sky work from 18:00-05:00 primarily with KOSMOS, and then in-dome resets after 05:00. Engineering tasks completed: - Quick Mirror Cover check - Measured KOSMOS spectrograph internal focus measurements at sunset and midnight - Measured KOSMOS slitviewer focus at high, center, low (systematically lower than last measurement by 200) - KOSMOS slitviewer instrument blocks for khigh, kosmos, klow - Adjusted boresight/imcenter values - New slitviewer plate scales appx 0.35"/pix (slightly different for each slit position though!) - Telescope focus sweeps with ecam, kcam, and kimage. - Instrument block for kimage, plus checked plate scale for camfocus=3200 (which wasn’t very different) - Checked focus on sky with kimage for different camfocus values - Reset TCC & axis controllers - Zeroed NA2 and Agile rotators ------- 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 -------------------------------------------------------------------------- 22:15 ecamera 374( -215) 69 61 6.1 5.6 6.2 5.6 5.8 ND3 1.15 23:00 kosmos 340( 790) 59 66 5.6 5.4 6.0 5.4 5.5 -- 1.40 23:27 kimage 330( 773) 47 71 5.6 5.3 5.9 5.3 5.4 -- 1.13 03:31 kimage 320( 703) 61 69 4.3 4.0 4.6 4.0 4.0 -- 1.18 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 49 21 15 267 (W) 342 clear none 17:00 45 14 17 255 (WSW) 461 clear none 18:00 43 15 22 245 (WSW) 592 clear none 19:00 44 21 17 266 (W) 362 clear none 20:00 44 16 23 266 (W) 444 mstly clr none 21:00 44 18 20 268 (W) 492 clear none 22:00 43 20 16 269 (W) 449 clear none 23:00 42 21 19 265 (W) 488 mstly clr none 00:00 42 23 15 256 (WSW) 454 mstly clr none 01:00 42 24 14 265 (W) 474 mstly clr none 02:00 41 24 17 226 (SW) 455 ptly cldy none 03:00 40 30 25 237 (WSW) 428 ptly cldy none 04:00 40 30 15 243 (WSW) 383 ptly cldy none 05:00 41 30 19 257 (WSW) 259 mstly clr none 06:00 40 31 16 264 (W) 290 mstly clr none Note: the wind was coming from the azimuth listed.
