Other than five minutes spent trying to figure out the guider issue, there were no problems. The night was clear and calm. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM ------------------------------------------------------------------------- 19:12 SPIcam 525( 1066) 48 71 11.8 14.5 13.2 14.2 12.0 SDSS-g 0.50 22:56 SPIcam 425( 793) -80 51 12.2 10.8 11.3 10.6 11.1 SDSS-g 0.35 01:41 dcamera 285( 522) -8 48 12.1 11.2 11.7 11.0 11.4 -- 1.15 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 56 37 5 352 (N) 321 clear none 17:00 56 39 3 306 (NW) 306 clear none 18:00 53 40 1 52 (NE) 347 clear none 19:00 53 35 5 18 (NNE) 231 clear none 20:00 52 38 8 2 (N) 211 clear none 21:00 52 36 9 359 (N) 251 clear none 22:00 50 37 10 16 (NNE) 226 clear none 23:00 53 29 4 114 (ESE) 179 clear none 00:00 55 29 6 166 (SSE) 191 clear none 01:00 54 31 6 169 (S) 177 clear none 02:00 53 30 4 183 (S) 161 clear none 03:00 54 30 3 197 (SSW) 153 clear none 04:00 54 30 2 197 (SSW) 212 clear none 05:00 52 32 2 224 (SW) 197 clear none 06:00 52 34 1 256 (WSW) 192 clear none Note: the wind was coming from the azimuth listed.
