APOLLO was having computer issues so they ceeded their time to GS02. Since Nada wasn't online yet, I went up to mount TSPEC for the last program of the night. She was online when I came back down and I gave the time to her for her program. No problems tonight and much better seeing for the 2nd half of the night. ------- 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 -------------------------------------------------------------------------- 17:51 ecamera 454( -589) 65 65 -0.6 2.2 2.9 2.3 0.1 ND2 2.00 18:52 ecamera 414( -712) 43 42 -1.9 0.2 0.7 -0.4 -1.4 ND1 2.40 00:30 ecamera 518( -663) 27 63 0.8 -0.6 -0.1 -0.5 0.6 ND4 0.82 04:39 tcamera 487( 627) -116 51 2.9 -0.4 0.2 -0.6 1.6 Ks 0.97 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 39 18 3 218 (SW) 297 clear none 17:00 36 17 1 218 (SW) 307 clear none 18:00 30 18 15 66 (ENE) 352 clear none 19:00 28 18 17 79 (E) 300 ptly cldy none 20:00 30 17 3 94 (E) 289 cloudy none 21:00 31 16 6 108 (ESE) 275 cloudy none 22:00 29 15 10 89 (E) 271 cloudy none 23:00 31 13 1 132 (SE) 257 mstly cldy none 00:00 32 11 2 237 (WSW) 297 mstly clr none 01:00 35 8 9 183 (S) 241 clear none 02:00 34 8 8 173 (S) 270 clear none 03:00 32 8 5 188 (S) 273 clear none 04:00 31 11 6 114 (ESE) 346 mstly clr none 05:00 37 1 5 194 (SSW) 322 mstly clr none 06:00 38 -3 8 192 (SSW) 278 mstly clr none Note: the wind was coming from the azimuth listed.
