G191B2B was near the screw and not near the boresight. I did a few test slews with the telescope but that didn't fix much of anything regarding pointing. See guider image K0004 for where te star landed. The second target was near the boresight When I changed slits to the center and again focused using G191B2B, again it seemed low. Russet thinks it may just be proper motion with G191B2B No telescope issues. I think 2 camera hangs tonight on ARCSAT/Flarecam ------- 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 -------------------------------------------------------------------------- 22:11 khigh 275( 829) 137 56 5.5 5.3 5.7 5.3 4.9 -- 1.16 00:18 kosmos 325( 850) 167 69 5.6 4.9 5.4 5.0 5.2 -- 0.85 03:04 tcamera 330( 1095) 173 49 5.0 4.4 5.0 4.4 4.7 Ks 1.00 05:38 APOLLO 305( 1589) 61 59 4.5 4.3 4.8 4.5 4.5 -- 1.00 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 46 21 10 251 (WSW) 116 cloudy none 17:00 44 21 13 187 (S) 121 cloudy none 18:00 44 22 13 201 (SSW) 232 cloudy none 19:00 42 20 15 196 (SSW) 486 cloudy none 20:00 42 20 15 191 (S) 477 cloudy none 21:00 41 20 9 212 (SSW) 541 mstly cldy none 22:00 41 20 17 217 (SW) 567 ptly cldy none 23:00 42 20 16 214 (SW) 569 ptly cldy none 00:00 43 22 22 259 (W) 365 mstly cldy none 01:00 42 22 17 259 (W) 321 mstly cldy none 02:00 42 23 17 266 (W) 336 ptly cldy none 03:00 41 23 17 280 (W) 365 ptly cldy none 04:00 41 23 15 265 (W) 441 mstly clr none 05:00 42 22 20 273 (W) 379 clear none 06:00 41 21 19 269 (W) 597 clear none Note: the wind was coming from the azimuth listed.
