We opened for a couple of periods while the humidity was borderline and the telescope warmish, and we did get some things done during that period. In the past few nights we have completed most of the tests that can be done quickly, but we would like some stable weather to do the remaining tests. ------- 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 57 51 1 243 (WSW) 1115 ptly cldy none 17:00 60 48 6 163 (SSE) 802 ptly cldy none 18:00 58 48 4 98 (E) 641 ptly cldy none 19:00 57 50 11 81 (E) 865 ptly cldy none 20:00 54 49 13 80 (E) 1044 mstly clr none 21:00 54 50 15 77 (ENE) 1080 mstly clr none 22:00 53 50 16 73 (ENE) 1119 ptly cldy humid 23:00 53 50 16 76 (ENE) 1001 ptly cldy humid 00:00 53 50 25 74 (ENE) 1070 mstly cldy humid 01:00 53 50 20 73 (ENE) 1196 mstly cldy humid 02:00 53 49 19 67 (ENE) 1110 ptly cldy humid 03:00 52 48 11 83 (E) 1098 ptly cldy none 04:00 51 48 12 82 (E) 1071 ptly cldy none 05:00 51 49 12 82 (E) 1434 ptly cldy humid Note: the wind was coming from the azimuth listed.
