    This is pretty suprising to me and I dont quite understand how the sequence could play out in this way. Regardless, it is a pretty interesting piece.

    The snapping of magnetic fields is known as magnetic reconnection.

    It appears that the observations support magnetic reconnection as the initiating phenomenon for auroral substorms.
