Opened enclosure at 18:30 with a few passing scattered clouds. Poor seeing (2.0-3.0 arc sec) at the start of the night and very unstable making it difficult to find good focus. Seeing improved considerable after 21:00 and was around 1 arc sec after 23:00. Observing Specialist, 2nd Shift: Noel Camron Hastings The second half started smoothly. Seeing was reasonable and instrument ran smoothly. --------------- INSTRUMENT FOCUS LOG ---------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM" --------------------------------------------------------------------- 18:45 DIS Slit -90(417) 203 55 -3.2/-0.6 113 13 none 1.95" 18:52 NA2 Gdr 457(56457) 206 54 -3.2/-0.8 95 13 none 1.85" 21:42 DIS Slit +30(392) -122 63 -2.2/-2.7 174 16 none 1.18" 23:47 NA2 Gdr 1600(390) -042 70 -3.4/-3.2 162 8 R 0.88" 00:15 DIS Slit 0(411) 71 50 -3.5/-3.4 181 10 none 1.04" 00:34 NA2 Gdr 1214(360) -31 62 -3.9/-3.6 172 7 R 1.32" 03:50 DIS Slit 70(493) 224 45 -3.1/-3.5 187 9 none 1.58" 03:55 NA2 Gdr -135(493) 224 46 -3.1/-3.5 184 8 none 1.47" ------------- WEATHER CONDITIONS ------------ Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 31 15 3 186 (S) 320 cirrus none 17:01 29 15 0 208 (SSW) 758 cirrus none 18:01 27 15 4 143 (SE) 1172 pt. cldy none 19:01 26 14 11 80 (E) 2561 mst. clr none 20:01 26 3 11 139 (SE) 884 mst. clr none 21:01 29 -8 11 159 (SSE) 498 mst. clr none 22:01 28 -1 13 178 (S) 895 clear none 23:01 28 -2 12 177 (S) 702 clear none 00:01 27 -3 10 181 (S) 542 clear none 01:01 27 -5 11 173 (S) 409 clear none 02:01 24 2 7 113 (ESE) 890 clear none 03:01 27 2 6 180 (S) 200 clear none 04:01 27 4 6 183 (S) 212 clear none 05:01 28 3 6 190 (S) 196 cirrus none 06:01 26 4 5 203 (SSW) 186 cirrus none note: the wind was coming from the azimuth listed.
