Thanks to Shane for fixing that! (The weather log is missing data for 18:00 because of this.) The UVA class tonight got to see some neat things with the eyepiece, and we finished up on Uranus so we took a peek at it through the TSPEC slitviewer as well before switching over to the echelle. We had pretty good seeing all night despite a few thin clouds. Part of the DIS instrument cover came undone so I repaired it. ------- 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 -------------------------------------------------------------------------- 18:08 dcamera 376( 986) -1 51 10.4 12.1 12.2 12.2 10.8 -- 0.95 21:16 tcamera 415( 1251) 69 54 9.1 9.2 9.9 9.0 9.2 Ks 0.97 21:33 ecamera 384( -33) 36 51 9.9 9.1 9.8 8.8 9.2 ND3 0.80 00:22 tcamera 438( 1275) 41 56 9.9 9.2 9.8 9.1 9.4 Ks 0.83 01:48 arctic 432( 1117) -51 40 9.9 8.9 9.4 8.8 9.3 SDSS_g 1.00 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 56 18 16 214 (SW) 924 clear none 17:00 52 19 13 221 (SW) 1150 clear none 18:00 mstly clr none 19:00 51 20 13 225 (SW) 1232 ptly cldy none 20:00 50 21 13 241 (WSW) 1332 ptly cldy none 21:00 48 21 8 238 (WSW) 1388 mstly clr none 22:00 50 21 10 224 (SW) 1160 clear none 23:00 51 18 11 260 (W) 1102 clear none 00:00 51 17 16 298 (WNW) 644 clear none 01:00 50 18 7 262 (W) 678 clear none 02:00 50 18 11 265 (W) 877 clear none 03:00 50 18 10 267 (W) 793 mstly clr none 04:00 50 18 9 266 (W) 790 ptly cldy none 05:00 50 19 9 268 (W) 809 ptly cldy none 06:00 49 19 9 267 (W) 811 ptly cldy none Note: the wind was coming from the azimuth listed.
