How Aurora Tracker Works

Aurora Tracker keeps an eye on geomagnetic activity around the world and alerts you when the Northern Lights might be visible from your location.

The system gathers live data from space weather services and calculates how far the auroral oval extends based on the current Kp index, a global measure of geomagnetic disturbance.

Your position is compared to the edge of this auroral zone using precise geographic formulas (yes, real math stolen from very skilled mathematicians!). If conditions look promising, Aurora Tracker sends you a notification so you don’t miss the show in the sky.
