How would a large geomagnetic storm affect communication on Earth?

During geomagnetic storms, the ionosphere gets altered and it resulted in the distraction of the high-frequency radio communications and navigation.

Explanation:

A geomagnetic storm also popularly known by the term a solar storm refers to a transient disruption of the magnetosphere of the earth prompt by a solar wind shock wave that strikes with the magnetic field of the earth. On the surface of the Earth, a magnetic storm is characterized by a sudden decrease in the power of the Earth's magnetic field. The decline spans range about six to twelve hours and following it the magnetic field starts to restore to normal in a few days. It affects the global position system thus disrupting the communication on Earth.
