What effect does high geomagnetic activity have on the auroral ovals?
Answer
The ovals expand and push viewing boundaries toward the equator
During periods of intense solar storms, the geomagnetic field experiences significant fluctuations that cause the auroral ovals to expand. This expansion effectively pushes the boundaries of where the lights can be seen away from the polar regions and toward lower latitudes, such as parts of central Europe or the northern United States.
