I contacted Bill and restarted the AgileICC in hopes that it would restart the cooling. Will monitor. DIS temps @ 20:10 194, 185 After 30 mins AGILE temps were not dropping at all. PR submitted. My observer was taking KOSMOS cals and paused the exposure. This seemed to disconnect KOSMOS from the torrent. Luckily I was just able to use a startNubs and get it to re-connect. DIS temps @23:00 191, 185 I opened at 23:00 but the clouds came back by 23:45 and I felt it safer to close back up. DIS temps @23:50 189, 185 I re-opened at 01:20 and we stayed open the remainder of the night. The temps dropped and humidity shot up near the end of the night but we plowed through. The outside railing wasn't wet and I was getting 3 different readings from the three diff DP sensors. Dust also climbed a bit and was elevated during the 2nd half but fopr the most part was between 3000-4000 cts. (outside). Winds changed from S to E, which I think was outflow from a storm to our east, this is probably where the temp and humidity came from. DIS temps @06:10 186, 181 No other issues tonight. The cooler temps seemed to help DIS red temp. ------- 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 -------------------------------------------------------------------------- 23:09 kosmos 389( 1249) 27 54 18.5 18.2 18.6 18.2 18.7 -- 1.65 01:36 kosmos 310( 1121) -147 50 16.2 17.1 17.7 17.1 16.4 -- 1.70 02:41 NICFPS 388( 1615) -46 42 15.9 16.2 16.9 16.2 16.0 J 0.98 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 67 53 6 141 (SE) 2092 cloudy none 17:00 66 57 11 115 (ESE) 2779 cloudy none 18:00 66 54 6 20 (NNE) 2574 cloudy lt rain 19:00 56 52 23 20 (NNE) 7371 cloudy none 20:00 63 41 17 14 (NNE) 1314 cloudy none 21:00 66 39 9 60 (ENE) 877 mstly cldy none 22:00 66 41 9 146 (SE) 1221 ptly cldy none 23:00 65 46 15 149 (SSE) 1933 ptly cldy none 00:00 65 46 15 165 (SSE) 2369 mstly cldy none 01:00 62 46 19 130 (SE) 3176 ptly cldy none 02:00 62 45 11 113 (ESE) 3241 mstly clr none 03:00 59 46 20 76 (ENE) 3183 mstly clr none 04:00 54 50 17 79 (E) 5403 mstly clr none 05:00 54 50 15 114 (ESE) mstly clr none 06:00 54 49 8 111 (ESE) 3563 mstly clr none Note: the wind was coming from the azimuth listed.
