Theta aurora over Antarctica. This image obtained in 1983 shows the auroral oval and a transpolar arc; the arc extends into the polar cap from local midnight, across the polar cap and joins with the auroral oval at local noon; motion of the transpolar arc in the dawn-dusk direction appears to be controlled by the direction of the interplanetary magnetic field along the dawn-dusk direction.
