Thanks Amanda. No problems tonight. I did not take Echelle IOL at mid or end of night since the Echelle was in use (moring observers were doing a long set of cals). ------- 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 -------------------------------------------------------------------------- 18:33 ecamera 480( 33) -67 45 4.9 5.2 5.5 4.8 4.9 ND3 1.41 20:37 ecamera 457( -29) -98 47 4.9 4.4 5.0 4.3 4.8 clear 1.18 00:08 ecamera 487( -102) -154 34 2.8 1.9 3.7 2.9 2.9 clear 1.75 05:17 APOLLO 425( 1541) 8 30 1.2 0.2 1.1 0.3 0.6 -- 2.00 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 44 8 30 238 (WSW) 681 clear none 17:00 44 9 17 265 (W) 499 clear none 18:00 42 9 17 268 (W) 581 clear none 19:00 41 6 16 290 (WNW) 589 clear none 20:00 41 8 17 261 (W) 724 clear none 21:00 41 9 19 254 (WSW) 670 clear none 22:00 40 8 19 260 (W) 807 clear none 23:00 39 6 19 268 (W) 639 clear none 00:00 38 6 23 256 (WSW) 641 clear none 01:00 37 7 22 257 (WSW) 668 clear none 02:00 35 9 11 251 (WSW) 815 clear none 03:00 35 11 15 251 (WSW) 903 clear none 04:00 36 7 16 258 (WSW) 636 clear none 05:00 34 10 18 261 (W) 662 clear none 06:00 34 7 12 265 (W) 573 clear none Note: the wind was coming from the azimuth listed.
