Schumann resonance is Earth-ionosphere cavity EM resonance. On 2026-08-02, SR1 is 7.83 Hz vs 7.83 Hz reference.
Data & Interpretation
On 2026-08-02, SR1 sits at 7.83 Hz against the 7.83 Hz reference. Kp 4.0 indicates geomagnetic conditions; high Kp means stress, low Kp a calm field. Signal quality is 93.
Reading the Spectrogram
The fundamental SR1 (~7.83 Hz today), SR2 (~14.1 Hz) and SR3 (~20.3 Hz) bands reveal coupling. For what is schumann resonance, broad-band energy often tracks the solar wind at %SOLAR km/s.
Why It Matters
Continuous monitoring links space weather to Earth effects. Today 7.83 Hz with Kp 4.0 and 93 signal — reliable Tomsk data every 24s.
- SR1 fundamental ~7.83 Hz persistent mode
- Kp above 5 = strong geomagnetic disturbance
- Signal 93 supports confident tracking
