Second half we opened at 03:15 but seeing was so extremely poor I could not even focus. We stayed open the rest of second half but could not get any usable data. No telescope problems. ------- 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 ----------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------- 16:00 54 28 6 76 (ENE) 958 clear none 17:00 51 30 24 71 (ENE) 2142 clear none 18:00 49 29 31 70 (ENE) 2423 clear none 19:00 47 29 22 67 (ENE) 2764 clear dust 20:00 44 28 38 74 (ENE) 3154 clear dust 21:00 41 28 32 66 (ENE) 3405 clear dust 22:00 39 27 23 83 (E) 3197 clear dust 23:00 36 26 40 73 (ENE) 2999 clear dust 00:00 35 24 23 72 (ENE) 2483 clear none 01:00 34 24 26 73 (ENE) 2532 clear none 02:00 35 22 27 76 (ENE) 2106 clear none 03:00 34 25 25 78 (ENE) 2007 clear none 04:00 34 24 22 84 (E) 1928 clear none 05:00 36 25 21 86 (E) 1750 clear none 06:00 36 29 17 87 (E) 1812 clear none Note: the wind was coming from the azimuth listed.
