2 massive 'active regions' on the sun have rotated into Earth's view

CMEs are explosive outbursts of plasma and charged particles capable of carrying billions of tons of material from the sun at speeds of hundreds of miles (or kilometers) per hour.
I think you meant, "hundreds of miles (or kilometers) per second.

CMEs typically reach the Earth in about a day. At hundreds of miles an hour, it would take about ten years for the CME to hit the Earth.
