A PR was sent (PR 2032). I'm not sure what caused the communication failure, but we were not able to talk with any of the axes until the agile rotator had been reset. We started the night with rain, clouds, fog, and then just high humidity until the winds shifted and we were able to open around 1:00 am. Seeing was moderate, but our OU02 student was able to get some good practice with TUI! ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- OU02 Agile I/U 02:46 03:15 Agile rotator lost communication ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 01:16 AGILE 656(-1002) 39 64 14.1 13.3 13.2 13.2 13.5 BG40 1.55 05:17 APOLLO 675( 1897) 104 35 13.0 12.2 12.8 12.0 12.2 530 1.70 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 64 52 6 229 (SW) 1205 mstly cldy lt rain 17:00 61 51 1 216 (SW) 1194 mstly cldy rain 18:00 58 53 9 58 (ENE) ptly cldy humid 19:00 58 53 13 75 (ENE) mstly clr humid 20:00 55 52 16 60 (ENE) clear humid 21:00 54 51 18 67 (ENE) mstly clr humid 22:00 52 49 19 76 (ENE) mstly cldy humid 23:00 53 48 21 57 (ENE) mstly clr humid 00:00 52 48 19 75 (ENE) mstly clr humid 01:00 58 43 18 65 (ENE) mstly clr none 02:00 56 44 3 344 (NNW) 964 clear none 03:00 57 43 1 287 (WNW) 604 clear none 04:00 54 43 6 354 (N) 553 clear none 05:00 56 47 2 259 (W) 1642 clear none 06:00 53 48 1 250 (WSW) 1906 clear humid Note: the wind was coming from the azimuth listed.
