What Is the KP Index?
The KP index is a global scale that measures the strength of geomagnetic activity—in other words, how likely you are to see the Northern Lights.
It ranges from 0 to 9:
0–2: Very low aurora activity, usually only visible near the poles
3–4: Moderate activity, visible in high-latitude regions like Tromsø
5+: Strong geomagnetic storm — aurora visible further south
The higher the number, the greater the chance of seeing the aurora.
At PolarForecast, we track the real-time KP index, updated every few minutes, so you always know when to head outside and look up.
