ARCTIC was giving bad images at checkout so I had to init, which dropped a quad, but recovery went smoothly and the camera was all settled down by the time second half started. I also had to power cycle the Stripchart Mac, which was completely frozen. With the moon east of the meridian, APOLLO was able to start early, but then the laser overheated before our time was up so we also ended a little early. It was a successful run nevertheless. Then the second half observer also allowed the first-half program to go a little long, so they got some extra time on both ends. ------- 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 -------------------------------------------------------------------------- 19:06 APOLLO 700( 2233) 25 29 17.4 19.2 18.9 18.5 17.2 530 1.50 20:01 ecamera 474( 171) 159 79 17.9 18.2 18.2 17.6 17.9 Clr 0.85 01:30 arctic 525( 1235) 203 73 16.8 16.3 17.0 16.2 16.4 J-CV 0.81 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 66 26 18 303 (WNW) 769 clear none 17:00 66 23 8 352 (N) 711 clear none 18:00 66 24 7 280 (W) 691 clear none 19:00 63 22 1 1 (N) 635 clear none 20:00 64 22 1 343 (NNW) 578 clear none 21:00 64 22 3 344 (NNW) 701 clear none 22:00 63 22 4 277 (W) 699 clear none 23:00 64 23 5 247 (WSW) 766 clear none 00:00 62 24 6 222 (SW) 723 clear none 01:00 63 25 3 254 (WSW) 916 clear none 02:00 62 27 3 258 (WSW) 832 clear none 03:00 64 26 10 286 (WNW) 898 clear none 04:00 63 25 9 314 (NW) 872 clear none 05:00 62 26 8 349 (N) 850 clear none 06:00 60 27 16 27 (NNE) 860 clear none Note: the wind was coming from the azimuth listed.
