Clear at the start of the night, with some clouds between 21:00 and 00:00, but it cleared up again for the rest of the night. We stayed open all night! Error "?LMSTOP clamp failed to fully close" when moving NA2 to BC1. Moving NA2 to TR2 to BC1 worked. 350 was an ok focus for HSAR. ------- 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 -------------------------------------------------------------------------- 19:52 arctic 423( 1184) 89 70 13.8 15.2 14.7 14.4 14.2 SDSS_r 0.80 02:44 APOLLO 350( 1699) 82 43 12.6 12.8 13.4 13.0 13.2 530 1.50 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 65 48 11 224 (SW) 495 ptly cldy none 17:00 65 49 9 237 (WSW) 443 mstly clr none 18:00 62 45 3 279 (W) 465 clear none 19:00 59 46 4 261 (W) 473 clear none 20:00 57 45 5 189 (S) 537 clear none 21:00 57 46 9 238 (WSW) 600 ptly cldy none 22:00 57 44 8 214 (SW) 548 ptly cldy none 23:00 57 42 8 234 (SW) 498 mstly clr none 00:00 57 41 9 236 (SW) 541 clear none 01:00 57 40 8 224 (SW) 910 clear none 02:00 56 43 10 196 (SSW) 858 clear none 03:00 55 40 11 208 (SSW) 423 clear none 04:00 56 41 8 254 (WSW) 368 clear none 05:00 54 40 9 258 (WSW) 334 clear none 06:00 55 38 11 251 (WSW) 339 clear none Note: the wind was coming from the azimuth listed.
