Planetary Geomagnetic Kp-Index

Kp: 1.67 • Quiet

The planetary Kp-index measures global geomagnetic storm activity caused by solar wind plasma. Values below 4 indicate normal stable magnetic conditions for orienteering.

0 (Quiet)4 (Unsettled)7 (Severe Storm)9 (Extreme)

Geomagnetic Science & Declination:

The World Magnetic Model (WMM) is the standard model used by the US Department of Defense, NATO, and the International Hydrographic Organization for navigation and attitude reference systems.

Because Earth’s geomagnetic pole drifts up to 50 km per year, magnetic declination changes over time. Online Compass Live calculates instantaneous magnetic variation corrections locally on your device hardware.
