But I was able to open briefly for a couple of APOLLO runs between the storms, and there was enough time for the first half program to get usable data after the second storm, so the night turned out to be decent for everyone PLUS a little fire prevention! Echelle has settled down in good shape, recent adjustments to the altitude drive appear to be working well, and there were no problems aside from some burnt toast setting off a fire alarm at 3 am. ------- 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 -------------------------------------------------------------------------- 20:15 APOLLO 750( 2013) -34 66 12.3 14.2 12.9 14.2 12.6 530 2.00 23:07 dcamera 455( 796) -22 65 12.1 12.2 12.2 12.1 12.1 - 1.30 02:52 ecamera 475( -136) 332 81 11.8 11.7 12.1 11.8 11.8 ND2 0.72 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 59 26 14 346 (NNW) 1239 mstly cldy none 17:00 61 27 16 312 (NW) 1353 ptly cldy none 18:00 57 25 5 304 (NW) 1335 ptly cldy none 19:00 54 31 6 349 (N) 1046 cloudy lt rain 20:00 54 27 6 313 (NW) 976 mstly clr none 21:00 54 27 1 259 (W) 1007 ptly cldy none 22:00 52 28 6 98 (E) 1105 ptly cldy lt rain 23:00 54 30 7 227 (SW) 1597 mstly clr none 00:00 52 29 6 206 (SSW) 1664 mstly clr none 01:00 54 28 12 244 (WSW) 1521 mstly clr none 02:00 54 28 12 234 (SW) 1646 ptly cldy none 03:00 53 28 12 234 (SW) 1692 clear none 04:00 52 29 13 207 (SSW) 2048 clear none 05:00 50 29 12 231 (SW) 1987 clear none Note: the wind was coming from the azimuth listed.
