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.
