A large solar filament has ruptured.. sending a blast of charged particles from layers above the suns surface in an "earth facing" direction.
UPDATE -- listed as a Class C .. confirmed "glacing blow" .. which basically just means possible earth interaction.. nothing major, but still a very impressive shot of the event...as we know .. even X class events can go by with no activity at all.
Of course, the possibility always exists of power grid disruption, communications interruptions, possible out of the ordinary auroras in more central latitudes... also watch for post arrival earthquake, and storm activity.
Monitor the ionospheric maps to see the ion flux as it arrives --- this sometimes shows the hard hit areas which tend to display earthquake / storm excitement upon arrival of charged particles.
