A primary route for the transfer of solar wind energy to the earth's ionosphere is via large-scale currents that flow along geomagnetic field lines. The currents, called 'Birkeland' or 'field aligned', are associated with complex plasma processes that produce ionospheric scintillations, joule heating, and auroral emissions. The Polar BEAR magnetic field experiment, in conjunction with auroral imaging and radio beacon experiments, provides a way to evaluate the role of Birkeland currents in the generation of auroral phenomena.
