We had a lovely, clear sky tonight with good seeing. CU04 took kosmos cals and grabbed a bunch of targets with the echelle, so now our two echelle trainees are pros! Since they were not able to come to site, we may have enjoyed some guider exposures of Saturn. No problems tonight. ------- 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 -------------------------------------------------------------------------- 18:41 APOLLO 500( 2295) -29 29 12.4 14.7 14.7 14.2 12.8 530 1.10 20:42 ecamera 290( 180) 131 80 11.0 12.6 13.0 12.1 11.6 ND1 1.07 21:52 ecamera 290( 133) 57 30 10.6 11.0 11.6 10.6 10.5 ND1 1.74 01:15 ecamera 331( 142) 358 44 12.8 10.7 11.4 10.6 11.6 ND4 0.75 04:41 arctic 275( 1159) 221 58 11.3 10.2 11.0 9.9 10.3 sdss-r 1.05 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 60 38 9 265 (W) 1597 clear none 17:00 62 38 1 221 (SW) 1818 clear none 18:00 61 37 2 169 (S) 1358 clear none 19:00 57 37 6 91 (E) 1416 clear none 20:00 53 37 13 111 (ESE) 1485 clear none 21:00 52 35 14 125 (SE) 1510 clear none 22:00 51 35 14 127 (SE) 1712 clear none 23:00 50 35 9 114 (ESE) 1717 clear none 00:00 54 27 11 127 (SE) 1447 clear none 01:00 54 24 6 93 (E) 974 clear none 02:00 52 27 7 2 (N) 1287 clear none 03:00 53 26 1 142 (SE) 1101 clear none 04:00 53 29 5 349 (N) 1226 clear none 05:00 52 28 6 19 (NNE) 1160 clear none 06:00 52 28 5 26 (NNE) 1122 clear none Note: the wind was coming from the azimuth listed.
