The Kp Index summarizes planetary geomagnetic disturbance on a 0–9 scale. It is not a Schumann frequency reading, but it helps explain why the live graph may look noisier during storms. When Kp rises, field-aligned currents and ionospheric dynamics shift — conditions that can modulate how cavity modes appear on surface sensors.
How we use Kp on this site
Our dashboard shows Kp alongside solar wind speed and IMF Bz so visitors can compare Schumann spectrogram changes with mainstream space weather metrics from NOAA-style sources. Elevated Kp does not automatically mean “harmful frequency change,” and quiet Kp does not guarantee a flat spectrogram.
Practical reading tips
- Watch 3-hour Kp trends, not>
- Note coronal mass ejection alerts from SWPC when bands widen for hours.
- Cross-check Tomsk feed delays during high traffic or maintenance windows.
