The mirror covers half closed after test slews again and I had to cycle them to get them to fully close (PR 2088). This problem repeated while closing at sunrise. We opened a little after 21:00 when the radar cleared up. We had a few clouds at first but they all went away and the night was great after that. 21:20 ecam focus measurement > 2 airmasses, closer to 1.5” based on next target FWHM. 22:14 klow focus measurement also high airmass. Motion error at 21:39 alt 45.9 slewing downward in the SE. ------- 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 -------------------------------------------------------------------------- 21:20 ecamera 505( 756) 127 27 19.9 22.9 22.5 22.5 21.4 Clear 2.05 22:14 klow 405( 1606) 90 25 19.1 20.7 20.9 20.4 19.6 -- 2.57 00:16 APOLLO 400( 2267) -25 44 20.8 19.7 20.2 19.6 20.0 530 1.30 01:16 ecamera 384( 466) -97 41 20.3 19.5 20.2 19.5 19.7 ND3 1.25 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 72 31 1 145 (SE) 1012 ptly cldy none 17:00 76 31 7 264 (W) 1843 ptly cldy none 18:00 80 31 11 242 (WSW) 1772 ptly cldy none 19:00 76 30 7 306 (NW) 2030 ptly cldy none 20:00 72 30 2 232 (SW) 2166 mstly clr none 21:00 69 33 8 178 (S) 2473 mstly clr none 22:00 67 35 5 162 (SSE) 2462 clear none 23:00 69 33 8 183 (S) 2362 clear none 00:00 68 33 8 187 (S) 2248 clear none 01:00 68 35 11 181 (S) 2682 clear none 02:00 68 35 14 203 (SSW) 2333 clear none 03:00 66 36 14 180 (S) 2403 clear none 04:00 67 35 9 184 (S) 2255 clear none 05:00 65 37 12 219 (SW) 2398 clear none 06:00 64 37 8 186 (S) 2470 clear none Note: the wind was coming from the azimuth listed.
