What is most likely to result in auroral propagation?
Pick an answer to check it.
Answer: C. Severe geomagnetic storms
Severe geomagnetic storms make the aurora active, which can reflect VHF signals and create auroral propagation. Quiet geomagnetic conditions do not produce aurora.
Tip: Big storm = aurora = auroral propagation.
