What's happened is that the size of the CME determines it's velocity..soooo the second larger (x1.6) has caught up with the smaller (still a large one also) and the combined electro-magnetic wave is knocking on the door. I'm not saying "the sky is falling", just we've never seen a CME this size, and traveling this fast, hit earth in the current era. In 1989 the aurora could be seen in Florida...interesting.
