NASA has explained that CME and coronal ejections are difficult to track for this very reason; they may start out and then alter their trajectory in very significant ways via sudden angle change.

Yes that's very true about the sun, and they're worried about the upcoming cycle causing damage satellites and electronics. A Faraday shield can protect your computer from a worldwide CME, but could be expensive. The solar wind too is highly variable throughout the solar system, and is shielded behind earth's magnetosphere,away from the sun, and nearer to the direction the asteroid approached.The Russian fireball orbit was magnetically compressed and came in from the sun in the opposite trajectory.
