About Schumann Resonance
The Schumann resonances are electromagnetic standing waves that form
in the cavity between Earth's surface and the ionosphere. The primary
frequency resonates at approximately 7.83 Hz.

About This Page
NOAA does not provide a live Schumann resonance feed here. This page uses
geomagnetic and magnetic-field conditions as a rough space-weather context
for ionospheric disturbance, which can affect resonance behavior indirectly.
