A severe geomagnetic storm is starting now (November 12 0000Z). But it's from the previous X-flares (X1.7 and X1.2), not the X5.1 flare.

  From what I’ve read that could be bad, because prior flares can clear a path (through the solar wind) for later flares to move faster and hit harder.

    Right, this three punch combo couldn't have been planned better.
