Polar Cap Optical Aurora Seen from ISIS-2
Although the optical aurora represents one of the least direct ways of observing magnetospheric particles and fields it is nevertheless one of the most powerful. The polar atmosphere acts as a giant scintillator, reproducing by virtue of its connection to magnetospheric field lines the complex fields, patterns, and motions of the magnetospheric plasma. Remote sensing of these optical emissions from a high altitude satellite can provide a detailed snapshot of the magnetosphere as it projects into the polar atmosphere.
