Dembicky Started the cooling fans around 18:30 tonight under mostly clear skies. Opened the enclosure at 19:00 and the observer started taking biases and sky flats at 19:23 after I finished checkout. Dust event at 23:30 shut us down for a couple hours. Finally subsided around 01:50 and I opened back up. Everything ran smoothly tonight. ------- FAILURE LOG ------- PROG INST FAILURE TIME S/E/G/D/O TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 20:20 SPIcam 30(1072) 133 47 12.0/14.2 264 8 R 0.79 20:31 NA2gdr 280(61280) 136 48 12.2/14.0 253 7 R 0.80 23:26 SPIcam 50(1055) 111 34 11.5/11.7 221 18 R 2.12 02:08 SPIcam 40(1008) -85 32 9.6/10.4 191 16 g' 1.75 02:13 NA2gdr 2122(63122) -85 32 9.6/10.4 191 16 R 1.43 04:05 SPIcam 70(998) -98 33 9.7/9.5 217 12 g' 1.02 04:14 NA2gdr -824(60175) -69 31 9.6/9.4 211 12 R 1.07 --------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 17:01 61 18 6 262 (W) 697 Clear none 18:01 60 19 7 282 (WNW) 779 Clear none 19:01 59 18 10 261 (W) 927 Clear none 20:01 53 17 7 266 (W) 965 Clear none 21:01 53 18 12 227 (SW) 1018 Clear none 22:01 54 21 14 206 (SSW) 861 Clear none 23:01 54 19 15 216 (SW) 831 Clear none 00:01 50 23 17 202 (SSW) 8002 Clear dust 01:01 50 25 8 181 (S) 4781 Clear dust 02:01 49 25 8 189 (S) 2282 Clear none 03:01 49 25 11 205 (SSW) 1450 Pt.
