Blue side began lower than red but they seem to be warming about the same rate, approx. 0.1 degrees C every 15 minutes. They seemed to peak around 20:30 and then they both started cooling back down. Since they warmed together and began cooling again as the ambient temps cooled it seems to be environmental, not necessarily equipment failure. Mostly clear skies. Fairly good seeing. ------- 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 -------------------------------------------------------------------------- 21:04 SPICAM -26( 758) 285 76 16.6 19.1 18.1 17.9 17.1 strom y 0.78 01:18 dis-slit 22( 350) -99 43 13.7 14.3 14.3 13.3 13.5 1.70 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 72 36 15 249 (WSW) 1163 clear none 17:00 71 36 10 261 (W) 1163 clear none 18:00 70 35 4 216 (SW) 1303 clear none 19:00 68 35 16 215 (SW) 1365 clear none 20:00 64 34 12 210 (SSW) 1361 clear none 21:00 61 33 3 246 (WSW) 1458 clear none 22:00 61 33 4 255 (WSW) 1410 mstly clr none 23:00 62 33 7 262 (W) 1511 mstly clr none 00:00 57 47 18 135 (SE) 1224 mstly clr none 01:00 57 47 9 117 (ESE) 1044 clear none 02:00 58 9 16 166 (SSE) 1401 clear none 03:00 57 45 15 149 (SSE) 1461 clear none 04:00 56 46 13 156 (SSE) 1055 clear none 05:00 55 46 14 127 (SE) 1007 clear none Note: the wind was coming from the azimuth listed.
