Restarted gcam at checkout. Restarted dataq. Opened at 5:30pm, as cals were being taking, and closed up at 6:40am. Weather was perfect all night, with sub-arcsecond seeing! Problems initializing the support library with arcsat again. Happened two times during the night. Lost the guide camera on arcsat too (needs to be reconnected). Had Jack help with pointing/focusing/general arcsat weirdness. NM05 started early, as no instrument change at NA2 was needed. BY02 logged off by the time I realized I could give them a few more minutes. ------- 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 -------------------------------------------------------------------------- 17:44 arctic 257( 1068) 96 66 5.6 8.8 8.0 8.6 7.7 SDSS_u 0.81 19:22 arctic 273( 961) 84 76 5.6 6.2 6.4 5.7 5.8 SDSS_u 0.84 22:49 tcamera 200( 950) 171 67 5.3 4.3 4.9 3.9 4.4 -- 0.93 00:17 ecamera 290( -196) -4 29 5.2 4.0 4.7 3.8 4.4 ND1 0.86 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 47 24 4 242 (WSW) 703 clear none 17:00 43 22 2 141 (SE) 644 clear none 18:00 42 22 1 201 (SSW) 629 clear none 19:00 43 20 2 193 (SSW) 321 clear none 20:00 43 21 8 146 (SE) 149 clear none 21:00 43 21 6 135 (SE) 124 clear none 22:00 41 22 10 136 (SE) 336 clear none 23:00 42 21 9 158 (SSE) 119 clear none 00:00 41 22 13 145 (SE) 309 clear none 01:00 40 23 14 149 (SSE) 826 clear none 02:00 40 24 13 145 (SE) 1049 clear none 03:00 40 26 16 144 (SE) 1441 clear none 04:00 39 26 13 159 (SSE) 1505 clear none 05:00 39 26 15 156 (SSE) 1430 clear none 06:00 39 27 13 159 (SSE) 1244 clear none Note: the wind was coming from the azimuth listed.
