The laser was firing and hitting all the targets. The BY01 class finished up their third night of training in fine style. The sky was clear. The seeing was EXCELLENT all night. The only thing we could have wish for was another hour on the eyepiece ;) No problems tonight. ------- 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 -------------------------------------------------------------------------- 18:53 APOLLO 350( 1720) -37 20 6.2 8.6 8.8 8.6 7.4 530 2.50 19:57 tcamera 377( 1102) -142 41 6.3 6.6 7.2 6.4 6.2 Ks 0.96 21:32 tcamera 449( 1150) -146 50 6.8 6.2 6.8 6.3 6.6 Ks 0.89 21:49 tcamera 449( 1151) -145 48 6.9 6.3 6.8 6.3 6.7 Ks 0.89 23:06 tcamera 467( 1154) 61 51 6.5 6.0 6.6 6.0 6.0 Ks 0.80 01:20 ecamera 389( -221) -73 60 6.2 5.1 5.7 5.0 5.4 ND1 0.77 05:33 tcamera 385( 1019) -28 60 6.4 5.0 5.6 4.8 5.2 Ks 0.84 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 47 23 18 328 (NNW) 717 clear none 17:00 50 21 10 319 (NW) 701 clear none 18:00 46 20 19 295 (WNW) 569 clear none 19:00 43 20 11 318 (NW) 591 clear none 20:00 44 20 16 322 (NW) 653 clear none 21:00 44 18 13 312 (NW) 556 clear none 22:00 44 18 17 315 (NW) 447 clear none 23:00 44 18 15 322 (NW) 461 clear none 00:00 42 18 14 285 (WNW) 473 clear none 01:00 43 18 16 314 (NW) 404 clear none 02:00 43 17 11 304 (NW) 479 clear none 03:00 44 18 10 314 (NW) 421 clear none 04:00 43 19 10 301 (WNW) 433 clear none 05:00 44 19 10 265 (W) 484 clear none 06:00 44 22 8 259 (W) 546 clear none Note: the wind was coming from the azimuth listed.
