ARCSAT had some issues so we didn't get on sky and observing until about 20:00. Mostly the issue was because the time was incorrect on arcsat-tcs. I had to initialize at zenith twice because I accidentally synced to the wrong star the first time and wasted a bunch of time trying to figure out why the pointing was still wrong. Once resolved, ARCSAT worked fine the rest of the night, although Denise reported that she could not send a 0.5m nightlog in the normal manner at the end of the night due to an error message ("The requested URL /cgi-bin/arcsatlog.cgi was not found on this server.") Weather was clear at the start and end of the night, but we had a bunch of clouds between about 21:00 and 01:00. We closed up around 06:15. ------- 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 -------------------------------------------------------------------------- 18:20 kosmos 506( 567) 215 50 10.0 1.1 2.3 1.7 2.1 -- 1.20 00:22 tcamera 448( 677) 202 65 10.0 0.7 1.6 1.1 0.9 Ks 0.88 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 20 217 (SW) 875 clear none 17:00 26 233 (SW) 543 clear none 18:00 20 211 (SSW) 698 clear none 19:00 23 204 (SSW) 614 clear none 20:00 20 218 (SW) 1059 mstly clr none 21:00 20 213 (SSW) 1181 ptly cldy none 22:00 20 220 (SW) 1035 mstly cldy none 23:00 15 232 (SW) 761 mstly cldy none 00:00 14 233 (SW) 637 ptly cldy none 01:00 13 214 (SW) 580 mstly clr none 02:00 14 226 (SW) 502 clear none 03:00 16 244 (WSW) 465 clear none 04:00 16 261 (W) 440 clear none 05:00 14 259 (W) 536 clear none 06:00 15 264 (W) 552 clear none Note: the wind was coming from the azimuth listed.
