By sunset it didn't look like the storms were moving toward us, but the threat was too close to open on time. As the radar returns diminished, we still had too many clouds for lunar ranging. The clouds thinned out somewhat after 21:30, and I decided it was safe enough to open. I tested out the NICFPS focus script some more, and of course clouds moved back in by the time I was done with that. Seeing was 1.2-1.5 arcsec (pretty bad for ) and variable. The observer was able to keep going through thin clouds, although it's not clear how much of the data will ultimately be useful. We had one weirdness with a DIS slitviewer image getting written to the observer's data file and upsetting TUI, but that was cleared up in about a minute. Just at the time of the program changeover, the wind shifted to the west, and by the time we focused spicam, seeing was drastically improved. Of course, that meant more work tracking the focus as temperatures drifted. Thin but widespread clouds gradually disappeared over the remainder of the night. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 22:23 nicfps 67(1491) 196 56 10.8/11.8 71 16 MK-Ks 1.3 23:32 nicfps 80(1493) 221 49 11.1/11.0 58 10 MK-H 1.18 01:19 SPIcam 85(1204) 115 57 12.2/10.7 302 1 r 0.80 01:22 NA2gdr -3495(29504)116 58 12.1/10.8 303 2 R 0.82 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 54 40 1 231 (SW) 1295 cloudy rain 17:01 55 42 2 46 (NE) 1381 cloudy none 18:01 55 42 18 65 (ENE) 1387 cloudy none 19:01 54 41 8 81 (E) 1450 cloudy none 20:01 53 42 18 73 (ENE) 1689 mstly cldy none 21:01 52 41 17 75 (ENE) 1717 ptly cldy none 22:01 51 42 15 74 (ENE) 1916 ptly cldy none 23:01 51 42 12 75 (ENE) 2174 ptly cldy none 00:01 52 41 9 49 (NE) 2074 mstly cldy none 01:01 53 39 3 62 (ENE) 2020 ptly cldy none 02:01 53 39 4 354 (N) 1732 ptly cldy none 03:01 51 40 1 2 (N) 1858 mstly clr none 04:01 51 38 7 7 (N) 1845 mstly clr none 05:01 50 40 8 43 (NE) 1763 mstly clr none Note: the wind was coming from the azimuth listed.
