Effects of Space Storms

Ground wave curves around the Earth's surface for thousands of kilometers.

Signals are attenutated when the lowest regions (below 75 km in day and 90 km at night) of the ionosphere, called the D and E regions, are disturbed. Effected by solar x-rays, geomagnetic storms, electron precipitation events, ionospheric substorms, Polar Cap Absorption (PCA) events and high altitude nuclear bursts).
