Echelle threw some weird exposures at checkout; the instchecks ThAr showed basically no light. The redflat from running echelle IOL also looked unusual. However, the blueflat and comp from the IOL script looked fine. I took more test exposures and they all looked okay. Possibly the filter wheel being out of place initially and blocking some light? Either way, it seemed to solve itself. The Agile rotator required a low-level init from talk2boxes during checkout, as the regular "tcc axis init rot" was not working. Sky was clear briefly around sunset. Clouds formed on top of us shortly thereafter and continued to do so for a few hours, but cleared up for the rest of the night by B half. We closed up at 05:30. It was an uneventful and successful night. ------- 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 -------------------------------------------------------------------------- 20:52 AGILE 643( -784) 70 46 16.1 17.3 17.4 16.8 16.2 BG40 0.96 23:01 AGILE 543( -946) 100 37 15.3 15.8 16.5 15.6 15.4 BG40 1.54 01:14 AGILE 643( -927) 83 65 14.5 14.5 15.2 14.6 14.6 BG40 1.40 02:49 AGILE 618( -969) 33 82 14.2 14.3 14.9 14.2 14.4 BG40 1.29 04:18 AGILE 568(-1029) -71 73 14.7 14.0 14.7 13.8 14.4 BG40 1.50 Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 65 53 6 258 (WSW) 513 mstly cldy none 17:00 67 52 9 228 (SW) 455 mstly cldy none 18:00 64 49 6 156 (SSE) 440 ptly cldy none 19:00 62 37 13 147 (SSE) 444 mstly clr none 20:00 61 42 9 182 (S) 478 mstly clr none 21:00 61 34 15 137 (SE) 524 mstly cldy none 22:00 60 33 12 129 (SE) 509 ptly cldy none 23:00 60 34 17 128 (SE) 879 ptly cldy none 00:00 59 33 12 124 (SE) 784 mstly clr none 01:00 58 32 10 117 (ESE) 923 clear none 02:00 58 33 8 88 (E) 992 clear none 03:00 58 31 8 87 (E) 975 clear none 04:00 58 32 8 90 (E) 853 clear none 05:00 60 31 9 114 (ESE) 692 clear none Note: the wind was coming from the azimuth listed.
