The filament event has thrown off a CME which is sheduled to impact the
magnetosphere around 1800z on the 6th. The NOAA animation is quite dramatic
and it looks like we will get it dead centre. the radio effect of this is
somewhat dependent on the direction of the field when it arrives, but expect
aurora and reduced LF signal levels from 6/7th for some following nights.
The region numbered 2335 I think which is fairly central has thrown off an X2.7 flare just after 2300z. Expect another possible CME arriving any time after 2400z on the 7/8th. If both of these reconnect we could experience long period of poor LF propagation. http://www.swpc.noaa.gov/products/wsa-enlil-solar-wind-prediction for the NOAA animation. AlanG3NYK |
