How can high geomagnetic activity benefit radio communications?
Pick an answer to check it.
Answer: A. Creates auroras that can reflect VHF signals
High geomagnetic activity can create auroras, and the ionized aurora can reflect VHF signals. Hams use this aurora mode for contacts that would not otherwise be possible.
Tip: Aurora reflects VHF.
