We also had elevated 1-micron dust counts for most of A-half. Wind speeds and dust counts came down under our limits a little before midnight, but pollen counts were high so we held off a little longer. The wind gusts went back up over the limit again around 00:40. Wind gust speeds came back down before 03:00, and pollen counts came down too, so we opened up for the end of the night. Seeing wasn't very good, very variable and stayed around 2" for most of the time. I left the fans in the reverse configuration in case that might help fend off some pollen. No telescope or instrument problems. Pollen Log: (waited for winds to calm down before putting out the pollen plates) 22:10-23:30 80.75 cts/cm2/hr, wind gusts > 35mph 23:40-23:55 92.0 wind gusts ~35mph 00:00-00:27 61.2 wind gusts ~35mph 00:35-01:05 47.2 wind gusts > 35mph 01:15-01:45 52.4 wind gusts > 35mph 01:55-02:35 51.3 wind gusts > 35mph 02:40-03:35 35.8 03:40-05:00 26.5 ------- 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 -------------------------------------------------------------------------- 03:07 AGILE 364(-1072) -26 65 10.4 11.6 14.2 11.6 11.4 BG40 1.40 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 64 13 23 265 (W) 2226 clear none 17:00 67 14 34 254 (WSW) 2271 clear none 18:00 64 17 32 266 (W) 3951 clear dust 19:00 63 17 31 259 (W) 4842 clear dust 20:00 60 19 39 265 (W) 7119 clear dust 21:00 58 20 36 244 (WSW) 5825 clear dust 22:00 58 18 14 249 (WSW) 5169 clear dust 23:00 56 13 26 269 (W) 6063 clear dust 00:00 54 14 19 267 (W) 2250 clear none 01:00 53 16 26 274 (W) 2022 clear none 02:00 52 22 24 278 (W) 2113 clear none 03:00 50 23 24 267 (W) 1668 clear none 04:00 49 24 20 281 (W) 1486 mstly clr none 05:00 48 25 12 275 (W) 1729 mstly clr none Note: the wind was coming from the azimuth listed.
