I was NOT able to bring back the upper left quad, only the lower right quad. I informed Bill but will try to restore it tomorrow. - agile kept aborting images at checkout giving the error: dark time=... finished; warning: debug=" _finishExposure shutting down cnt=5 cntDone=1" I left it until I had looked at arctic. However, when I came back to agile at 22:00, it was working fine! So...I don't know what the issue was. We started with clear skies and terrible seeing. However, clouds started rolling in and seeing...some what improved. During B half, the seeing was great! But the clouds were worse. Well, until the wind started gusting up over 30 mph, but we were never at the point of closing. ------- 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 -------------------------------------------------------------------------- 19:22 ecamera 526( -493) -33 25 10.0 0.0 0.4 -0.2 -0.1 Clear 2.68 20:43 ecamera 444( -614) -26 41 10.0 -0.5 -0.1 -0.7 -0.6 ND2 1.62 01:09 tcamera 396( 561) 229 62 10.0 -0.7 -0.5 -1.1 -0.8 Ks 0.83 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 21 234 (SW) 512 clear none 17:00 18 259 (W) 525 clear none 18:00 18 268 (W) 425 clear none 19:00 15 268 (W) 438 clear none 20:00 14 261 (W) 490 clear none 21:00 23 250 (WSW) 486 clear none 22:00 23 267 (W) 528 clear none 23:00 18 273 (W) 535 mstly clr none 00:00 18 255 (WSW) 534 ptly cldy none 01:00 17 269 (W) 504 ptly cldy none 02:00 17 267 (W) 415 ptly cldy none 03:00 18 256 (WSW) 428 ptly cldy none 04:00 23 258 (WSW) 454 mstly clr none 05:00 17 268 (W) 312 clear none 06:00 16 264 (W) 1183 clear none Note: the wind was coming from the azimuth listed.
