Fundamental Frequency: 7.70 Hz (baseline: 7.83 Hz) → 1.7% deviation
Amplitude: 11.2 pT · Kp: 1.1 · Signal: moderate
Today's fundamental frequency of 7.70 Hz near the 7.83 Hz baseline (moderate deviation), indicating undisturbed ionospheric coupling.
The Tomsk SOS spectrogram reveals elevated activity across SR1–SR5, with well-defined harmonic structure.
A 7.70 Hz reading near baseline points to normal waveguide propagation. The ionospheric cavity is undisturbed today.
