Earth's fundamental resonance frequency continues to hover around 7.83 Hz today. Tomsk Space Observing System (SOS) data shows global lightning activity is at average levels. Low deviation in fundamental mode SR1 indicates a healthy ionosphere-ground interaction.
Second harmonic (SR2) at ~14.3 Hz shows expected weak activity. Third harmonic (SR3) at ~20.8 Hz is normal. Amplitude values are in the 13-14 pT range, indicating healthy signal quality (93%+). Solar wind at 420 km/s, geomagnetic activity low-moderate.
Kp index today at 2.0, calm conditions. Solar wind in normal range, no CME activity. Under these conditions, Schumann resonance is in its most stable period — ideal environment for meditation and bio-feedback applications.
The 24-hour Tomsk spectrogram shows a slight increase during morning hours (06-09 UTC). This aligns with intensified lightning activity in the Asia-Pacific region. Evening hours (18-21 UTC) active in Europe-Africa. Night hours are quiet as expected.
