Is it true that Aurorae australis initiate in specific polar regions and follow directional movement patterns?
Yes. Peer-reviewed studies confirm that aurorae in polar regions originate in specific high-latitude locations and exhibit organized directional movement patterns tied to ionospheric convection and solar wind interactions.
