Only the second makes any kind of sense  The Southern lights can't logically be see north of the equator, becomes they come (by definition) from activity around the South (Magnetic) Pole.  The solar wind radiates from the sun in all directions equally, and it can't "move" because there's no where for it to go to.  It isn't pointing in any one direction, but rather in all directions.  It's true that the Earth's poles can interchange, but this is a *cause* of changes in the Earth's magnetic field, not an *effect."
