Model diagram, not a live measurement
Today's rhythm
A modelled reconstruction of the frequency spectrum (0–40 Hz) across 24 hours UT, derived from today’s state. This is not a live measurement.

How to read a spectrogram · colors are not frequencies
A colored live monitor shows ELF signal intensity over time and across frequency bands. It helps you see amplitude, peaks or local station noise; it does not show the Earth's fundamental frequency "rising".
Colors
Stronger color means higher signal intensity at that time and band. It does not mean planetary energy, Earth's mood or a health effect.
Vertical lines
They often indicate a short broadband impulse, dropout or local station interference. They are not proof that the frequency jumped.
Peaks and bright spots
They may relate to strong lightning, storm systems or technical noise. On their own they do not prove a global event.
Noise and gaps
They are part of measurement: a station can have poor conditions, maintenance or outages. It does not mean the Schumann resonance disappeared.
Frequencies
Watch mainly the horizontal bands near 7.83 / 14 / 20 / 27 / 34 Hz. f1 = 7.83 Hz stays stable; mainly intensity changes.
This panel explains a spectrogram as a measurement display of intensity. The daily state in the app is a model, not live measurement, and contains no health or causal claims.
Solar cycle and environmental stability
Axis B — Sun-driven ionospheric stability (solar cycle 25), NOT frequency.
SC25 declines toward minimum around 2030 → the curve falls.
f1 = 7.83 Hz stays stable and independent of the solar cycle — the chart does NOT show frequency.
≈ Modelled estimate, not a measurement. Correlation ≠ causation.
My year in rhythm
Tab enters the current day in the map. Arrows change day or month, Home/End jumps to the start or end of the month.
≈ Modelled band forecast (1–5), not a measurement. Calm = band ≤2, stormy = stormy peak.
Wave interference
When two waves meet, they add up. Move the second wave’s phase and watch amplification or cancellation appear.
- Wave 1
- Wave 2 (shifted phase)
- Combined (sum)
It is constructive interference of reflected waves in the Earth–ionosphere cavity that excites the resonance. This is a modelled illustration of the principle, not a live measurement.
Where the wave resonates
A conductive cavity forms between Earth’s surface and the lower edge of the ionosphere. Inside it, electromagnetic waves close into standing patterns — the Schumann resonances.
Around 50 lightning strikes hit the planet every second. Each discharge sends a brief electromagnetic pulse into the cavity.
Waves whose wavelength fits the cavity’s circumference add up into standing patterns. The fundamental mode sits near 7.83 Hz — set by Earth’s size and the speed of light, and therefore stable.
