Red and Blue images looked like biases. PR submitted. During initial test slews: Alt slip at 71, 62, 53-21 deg going downward on initial slew. Alt slip at 31, 53-78 going up Alt slip at 72, 62 - 21 2nd slew going down Alt slip at 31, 47, 53-78 2nd slew going up No filters were showing in NA2 guider. reloading parameters file fixed. The focus file for NA2 with ARCTIC was 35000, I did a gmech focus offset to fix back to around 0. We had one instance of ARCSAT closing due to humidity. It was only around 75% so I disabledd the weather and that allowed observations to continue. No telescope problems. ------- 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 -------------------------------------------------------------------------- 19:10 kosmos 321( 1406) 123 59 12.8 15.6 15.1 15.0 14.1 -- 0.85 01:14 arctic 303( 1314) 137 55 13.8 12.9 13.6 12.9 13.2 4170 0.78 01:15 NA2gdr -1760(36239) 137 55 13.9 12.9 13.5 12.9 13.2 R 1.02 06:07 APOLLO 275( 1891) 54 82 12.0 11.6 12.2 11.5 11.8 -- 1.10 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 63 14 6 251 (WSW) 277 clear none 17:00 62 13 10 279 (W) 256 clear none 18:00 59 8 2 330 (NNW) 71 clear none 19:00 57 7 6 357 (N) 203 clear none 20:00 57 5 4 349 (N) 104 clear none 21:00 57 6 3 281 (W) 117 clear none 22:00 56 12 3 252 (WSW) 241 clear none 23:00 57 21 6 261 (W) 407 clear none 00:00 57 28 6 264 (W) 670 clear none 01:00 57 28 9 265 (W) 692 clear none 02:00 56 27 9 241 (WSW) 630 clear none 03:00 57 27 9 264 (W) 631 clear none 04:00 55 27 11 247 (WSW) 736 clear none 05:00 55 28 10 228 (SW) 974 clear none 06:00 55 28 12 240 (WSW) 1122 clear none Note: the wind was coming from the azimuth listed.
