Humidity crept upward during second half but didn't quite reach the limit before twilight. Echelle was fine during checkout, but partway through cals it started giving images that were all zeroes. I was able to get it back by restarting the echelle ICC program. Some of the time lost was due to delay in recognizing the problem. There was a motion error on a slew at 01:38, and I did a longer slew for recovery, which cost just a few minutes. Otherwise, everything went smoothly. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- UC01 E I/S 17:50 18:11 Ech imgs all zeros, ICC restart UW11 T T/H 01:37 01:41 rot+alt motion error on slew ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 17:47 ecamera 315( -775) 237 50 4.3 5.8 5.3 5.2 4.2 ND4 0.83 23:32 SPIcam 350( 324) -164 45 3.6 3.0 3.5 3.0 3.2 r 0.57 01:45 tcamera 380( 395) -86 56 3.6 3.1 3.6 3.2 3.4 Ks 1.27 04:08 dcamera 340( 176) 84 43 3.1 3.1 3.7 3.2 2.9 - 1.35 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 46 28 6 251 (WSW) 496 mstly clr none 17:00 40 28 6 251 (WSW) 575 mstly clr none 18:00 40 28 12 231 (SW) 603 mstly clr none 19:00 39 30 8 228 (SW) 636 mstly clr none 20:00 39 30 7 203 (SSW) 652 mstly clr none 21:00 38 31 12 208 (SSW) 966 mstly clr none 22:00 39 28 9 194 (SSW) 895 clear none 23:00 39 28 8 239 (WSW) 693 clear none 00:00 38 31 8 265 (W) 809 clear none 01:00 39 30 8 268 (W) 753 clear none 02:00 38 30 9 274 (W) 804 clear none 03:00 38 30 8 275 (W) 737 clear humid 04:00 39 31 7 267 (W) 855 clear humid 05:00 37 31 7 264 (W) 886 clear humid 06:00 37 31 10 267 (W) 859 clear none Note: the wind was coming from the azimuth listed.
