Yes, but it's very localized. The magnetic field of earth is typically modeled as a dipole where the magnetic field strength is the same as you go around the equator at the same altitude.
Maybe with northern lights over equator, I'd have to think about it more, but it's odd to think of an aurora where the magnetic field lines are parallel with the ground rather than normal to the ground (particles are much more mobile along field lines rather than across field lines in plasmas).
