Six independent observatories on three continents. Each captures the same electromagnetic signal — their agreement is what makes the data trustworthy.

Open forecastWhen all six stations agree, you can trust the score. When they diverge, it usually means a local disturbance (power grid noise, thunderstorm overhead) rather than a global electromagnetic event. We weight all stations equally and display the average.
Each station uses a ground-based VLF receiver to capture the same standing waves between the Earth's surface and the ionosphere. Because the stations span three continents, a signal that shows up on all six is almost certainly a real global event — not local interference.
Capture
Every hour, our pipeline downloads the latest spectrogram from each station — a visual snapshot of electromagnetic energy between 0 and 50 Hz.
Analyze
A pixel analyzer measures brightness across the five Schumann bands (7.83, 14.3, 20.8, 27.3, 33.8 Hz). An AI vision model then examines the full image for subtler patterns.
Cross-validate
We compare readings from all six stations. If one disagrees sharply, it likely reflects local noise rather than a global event.
Score
The final 0–100 score is the equal-weight average across stations. Status levels — Calm, Elevated, Active, Storm — are derived directly from this number.
