Your power grid just flickered. Somewhere above Earth's magnetosphere, the Sun unleashed a stream of charged particles traveling at 800 km/s. In the next 8–12 hours, that plasma will collide with our magnetic shield, and whether it triggers a regional blackout or just makes auroras dance depends on four precise measurements—all feeding into Pandita's Brain Dashboard in real time.

Geomagnetic storm risk isn't guesswork. It's a weighted calculation pulling live space weather data into a single AI risk score. Here's exactly how we compute it.

THE MAGNETIC STORM RISK FORMULA

Pandita's Brain Dashboard ingests four solar and magnetospheric signals, each weighted by historical impact on terrestrial infrastructure:

Kp Index (45%)
Measures planetary magnetic disturbance (0–9 scale). Kp ≥ 6 triggers widespread transformer stress; Kp ≥ 8 risks continent-scale outages. Currently 2.0 (quiet).
Primary Trigger
💨
Solar Wind Speed (25%)
Velocity of plasma ejected from the Sun's corona. Above 500 km/s indicates active coronal mass ejection (CME). Faster winds = harder magnetospheric compression. Currently unavailable.
Energy Driver
🧲
Bz Component (20%) + X-Ray Flux (10%)
Bz (southward magnetic field) opens Earth's magnetosphere to solar wind; negative Bz is the primary trigger mechanism. X-ray flux reveals flare intensity upstream. Currently unavailable.
Gate + Context

WHY Bz IS THE TRIGGER

Of all four signals, the Bz component is the critical threshold. When interplanetary magnetic field (IMF) rotates southward (negative Bz), it reconnects with Earth's equatorial magnetosphere. Think of two magnets aligned opposite—the field lines snap and rearrange, dumping energy into the ionosphere. Northward Bz? The solar wind bounces harmlessly off. This asymmetry is why Bz dominates storm severity prediction, even at lower weighting, because it's binary: either the gate opens or it doesn't.

⚠ LATITUDE MATTERS

High-latitude regions (55°N–70°N and 55°S–70°S) experience peak induced currents; equatorial zones see minimal ground effect. Transformer damage clusters at 40°–60° magnetic latitude. Check your city's geomagnetic risk on Pandita's Disaster Report (panditadata.com/disaster_report) for local exposure.

WHAT MAGNETIC STORMS DAMAGE

1
Power Transformers
Geomagnetically induced currents (GIC) saturate cores, causing overheating and multi-day outages (Quebec 1989: 9 million without power for 12 hours).
2
Satellites & Navigation
GPS accuracy degrades; LEO satellites experience atmospheric drag surge and radiation damage.
3
Pipelines & Telecom
Metal structures corrode under GIC; fiber-optic repeaters reset or fail.
