Large scale electric currents flow between the boundaries of the magnetosphere and the ionosphere. Energetic charged particles inside the magnetosphere form the radiation belts and produce the visible Aurora Borealis. Space Physics research at the University of Washington has both strong experimental and theoretical components. We have active programs of balloon, rocket and satellite experiments as well as plasma theory, modeling and simulation. This interplanetary shock resulting from the CME produced intense auroral activity when it reached the Earth one day later.
