It was beautiful and clear all night! Seeing degraded slightly as the night went on, but we were still around 1.5" at high airmass. OU05 was scheduled for B half but NM01 called in their ToO. I'm sorry for taking their time by OH MY GOODNESS!!! What an absolutely perfect alignment of phase, solar storms, and terrestrial weather for studying Venus!! I never thought I would get this lucky! I changed from NA2 to NA1 via talk2boxes and the casshole, not climbing on the telescope or moving the tertiary by hand. It was the first time I did it on my own and it took me about 40 min for everything to be said and done. 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 -------------------------------------------------------------------------- 20:22 tcamera 397( 1831) 224 42 17.7 18.5 18.7 17.9 17.8 Ks 0.99 02:01 ecamera 343( 395) 89 18 15.8 15.2 15.9 15.1 15.4 ND3 1.32 02:21 ecamera 350( 391) 86 22 15.9 15.1 15.8 14.9 15.3 ND3 1.39 04:12 ecamera 313( 295) 68 45 15.2 14.3 15.0 14.2 14.5 ND3 1.47 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 74 41 22 248 (WSW) 616 clear none 17:00 72 38 19 265 (W) 612 clear none 18:00 69 35 15 259 (W) 709 clear none 19:00 66 37 18 256 (WSW) 874 clear none 20:00 63 35 14 266 (W) 551 clear none 21:00 63 36 15 267 (W) 606 clear none 22:00 63 37 14 265 (W) 504 clear none 23:00 61 39 15 267 (W) 620 clear none 00:00 62 39 13 282 (WNW) 607 clear none 01:00 61 39 14 282 (WNW) 512 clear none 02:00 61 38 16 296 (WNW) 560 clear none 03:00 60 37 10 281 (W) 522 clear none 04:00 59 37 10 302 (WNW) 675 clear none 05:00 59 38 13 305 (NW) 579 clear none 06:00 58 37 12 280 (W) 575 clear none Note: the wind was coming from the azimuth listed.
