Today's X1.4-class solar flare released a Type O Coronal Mass Ejection, traveling at approx. 1,400 km/s. It is traveling Earth bound but and its impact will create some geomagnetic storms, currently estimated between G2 and G4 levels. That could produce aurorae as far South as Northern California and Alabama and central UK/ Europe.
