Earth’s electromagnetic field spectrum global electromagnetic resonances, excited by lightning discharges in the cavity formed by the Earth’s surface and the ionosphere. Solar matter (which includes charged particles–electrons and protons) is ejected from the sun.
Electromagnetic radiation at wavelengths of 100 to 1000 Angstroms (ultraviolet) ionizes the F region, radiation at 10 to 100 Angstroms (soft X-rays) ionizes the E region, and radiation at 1 to 10 Angstroms (hard X- rays) ionizes the D region.
Ionosphere
The ionosphere /aɪˈɒnɵˌsfɪər/ is a region of Earth’s upper atmosphere, from about 60 km (37 mi) to 1,000 km (620 mi) altitude as quasi-standing electromagnetic waves that exist in the Earth’s ‘electromagnetic’ cavity (the space between the surface of the Earth and the Ionosphere)
Most of the disturbances to propagation come from solar flares and coronal mass ejections (CMEs). The solar flares that affect propagation are called X-ray flares due to their wavelength being in the 1 to 8 Angstrom range. X-ray flares are classified as C (the smallest), M (medium size), and X (the biggest). Class C flares usually have minimal impact to propagation. Class M and X flares can have a progressively adverse impact to propagation.
Schumann Resonance going Crazy
is the frequency of the electromagnetic field of the earth. It is supposed to be steady at 7.83 Hz, but it can vary slightly.
Colorado Springs
This phenomenon was first observed by the electrical pioneer Nikola Tesla, perhaps most famous for winning the “war of currents” against Thomas Edison and establishing alternating current (AC) as the principal means of transmitting electricity.
