Second half user started early due to insufficient time for first half user to complete science exposures. Humidity caused closure for and hour but was able to reopen under stable high humidity conditions. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:19 dis-slit 319( -313) 41 49 0.9 3.0 3.3 2.2 2.2 clear 1.66 23:41 TSPEC 292( -104) -108 37 1.4 1.4 2.3 1.1 1.3 clear 1.09 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 36 28 10 273 (W) 257 ptly cldy none 17:00 34 29 13 272 (W) 328 cloudy none 18:00 34 29 10 263 (W) 273 cloudy humid 19:00 33 30 9 261 (W) 367 cloudy humid 20:00 33 30 8 277 (W) 394 ptly cldy humid 21:00 34 30 17 316 (NW) 177 mstly clr humid 22:00 33 30 16 321 (NW) 178 clear humid 23:00 33 30 12 344 (NNW) 165 clear humid 00:00 34 30 18 313 (NW) 105 mstly clr humid 01:00 34 30 15 305 (NW) 123 mstly clr humid 02:00 34 31 16 317 (NW) 80 mstly clr humid 03:00 35 31 18 307 (NW) 56 mstly clr humid 04:00 34 31 18 302 (WNW) 57 mstly clr humid 05:00 36 30 22 306 (NW) 45 clear none 06:00 35 31 19 290 (WNW) 65 clear humid Note: the wind was coming from the azimuth listed.
