The usual adjust and it moves way too much one way, re-adjust and it moves way too much the other way. I eventually just moved it one step and it calibrated close enough to where I needed it. This is a know behavior with this bay/grating. Dust and wind kept us closed for about 30mins at the start of the night. Agile guider again refused to work initially, it reported running another command. I had to do a startNubs on afocus to get it to work. I left the telescope at altitude 75 deg since my observer needed cals with both AGILE and DIS. No telescope problems tonight. ------- 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 -------------------------------------------------------------------------- 20:19 dcamera 568( 949) 121 62 10.9 13.0 13.4 12.9 11.3 -- 1.40 01:10 dcamera 489( 641) 76 52 8.3 8.0 8.7 7.8 7.8 -- 2.00 02:01 AGILE 589(-1295) 130 37 7.5 7.4 8.1 7.1 7.2 SDSS_i 1.70 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 61 16 18 258 (WSW) 1053 mstly clr none 17:00 60 15 21 233 (SW) 1488 mstly clr none 18:00 58 13 35 260 (W) 2451 mstly clr none 19:00 55 11 30 263 (W) 5349 ptly cldy dust 20:00 52 10 18 259 (W) 2583 ptly cldy none 21:00 51 12 16 268 (W) 2612 ptly cldy none 22:00 50 11 14 276 (W) 1271 ptly cldy none 23:00 49 10 14 277 (W) 1139 mstly cldy none 00:00 48 12 21 279 (W) 3747 ptly cldy none 01:00 47 13 10 280 (W) 2050 clear none 02:00 46 14 6 272 (W) 1325 clear none 03:00 45 15 7 350 (N) 1084 clear none 04:00 44 16 12 341 (NNW) 1280 ptly cldy none 05:00 43 18 4 313 (NW) 1360 cloudy none Note: the wind was coming from the azimuth listed.
