The auroral oval is an annular ring around each geomagnetic pole where aurora is most likely to occur. The
aurora is caused by the excitation of particles from the Sun spiralling in the geomagnetic field near the
poles resulting in the release of energy in different forms, including light. The above model attempts to
predict the location of the auroral oval around the geomagnetic south pole.
