Simply telling if it’s possible to see the northern lights (aurora borealis) at your current location or a given location in the map. Good help on planning your aurora-hunting trip.
The KP index and Magnetic latitude are also given if you are professional enough to understand.
Continued use of GPS running in the background can dramatically decrease battery life.
