The Agile rotator got lost during observations, we only had enough time to do a non-rotating inst. block. So I had an issue with the tertiary clamp not locking when I moved from NA2 to TR2. I moved to BC1, which clamped, and then moved to TR2 (from opposite direction), which then sucessfully clamped the tertiary. NICFIP ICC crashed at around 04:18, when my observers 200s exposure read out but never wrote and just hung. I did the usualy restart and commands from the wiki to get it going again in about 4 minutes. Russet/Nancy got Agile flats at the end of the night. No other 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 -------------------------------------------------------------------------- 20:30 AGILE 230(-1616) -98 23 -1.9 -1.0 -1.1 -1.9 -1.9 Z 1.20 21:44 ecamera 335( -436) -22 55 -2.4 -1.6 -1.8 -2.7 -2.5 ND1 1.06 01:21 NICFPS 295( 940) 31 67 -2.3 -3.2 -2.5 -3.3 -2.7 J 0.85 03:40 NICFPS 260( 967) -144 64 -1.2 -1.9 -2.2 -3.0 -2.1 J 0.62 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 32 18 16 321 (NW) 2358 mstly clr none 17:00 32 16 2 227 (SW) 879 mstly clr none 18:00 32 14 9 303 (WNW) 759 mstly clr none 19:00 31 12 14 310 (NW) 692 clear none 20:00 29 11 8 271 (W) 709 clear none 21:00 28 15 6 266 (W) 663 clear none 22:00 28 15 2 249 (WSW) 767 clear none 23:00 28 17 2 237 (WSW) 799 clear none 00:00 29 15 8 294 (WNW) 688 clear none 01:00 28 16 8 322 (NW) 678 clear none 02:00 28 17 8 330 (NNW) 760 clear none 03:00 29 17 7 356 (N) 797 clear none 04:00 30 17 5 6 (N) 786 clear none 05:00 30 17 8 14 (NNE) 741 clear none 06:00 30 15 13 27 (NNE) 750 clear none Note: the wind was coming from the azimuth listed.
