Spent a few minutes at the start of B-half refocusing kcamera for khigh; lower by about 1000 than previous values and the slit is about 100 pixels higher on the detector than it was previously. But it worked! Updated PR. This time is counted as equip. Center and low slits will likely need focus adjustments as well. We had thin clouds on and off and some humidity and dust (which we closed up for about 45 minutes for; handheld dust counter measurements for the rest of the night were lower). Otherwise everything went well. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- NM04 KOSMOS I/H 00:25 00:40 Refocused kcam high ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 18:17 arctic 423( 931) -24 36 3.0 1.9 3.3 2.8 3.0 SDSS_r 1.43 19:52 ecamera 368( -272) -35 67 2.4 1.3 2.7 2.0 2.2 ND3 1.07 00:39 khigh 225( 502) 110 69 -0.8 -0.5 0.1 -0.8 -1.0 -- 1.70 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 37 7 17 129 (SE) 434 mstly cldy none 17:00 39 2 29 203 (SSW) 1141 ptly cldy none 18:00 37 0 16 164 (SSE) 380 mstly clr none 19:00 37 3 17 166 (SSE) 453 clear none 20:00 36 6 21 174 (S) 433 clear none 21:00 37 10 29 179 (S) 476 clear none 22:00 35 15 15 170 (S) 671 mstly clr none 23:00 33 17 11 182 (S) 865 mstly clr none 00:00 32 19 13 169 (S) 1078 mstly clr none 01:00 29 19 10 188 (S) 1344 mstly clr none 02:00 28 20 6 190 (S) mstly clr none 03:00 28 19 6 280 (W) 3263 mstly clr dust 04:00 26 17 10 304 (NW) 3111 mstly clr dust 05:00 24 17 2 343 (NNW) clear none Note: the wind was coming from the azimuth listed.
