    That sunspot has been crackling up some big flares. This morning at 0530 UTC it hit with an X1 flare aimed directly at Earth. It’s been blowing off M-Class flares all day long and then just now at 2145 UTC it blew another X-Class flare at us.

    Right now, it looks like we’re going to see the Coronal Mass Ejection arrive late on the 10th/Early 11th UTC. We’ve been seeing some R3 Radio blackouts. Sorry for all you lower shortwave listeners, the D-Layer absorption will be significant. However, this might be a good time to listen at 30 MHz and possibly higher.
