This page enables users to calculate the main rigidity cut-off for any incoming direction of the particle and for any altitude. The cut-off is calculated in the shifted dipole approximation, with the Stoermer's formula you can find here.

To perform Rigidity Cutoff Calculation please follow this link:


The Earth Magnetic dipole position and inclination, in addition to the magnetic moment value, are updated at November 2016. Rigidity Cutoff and  Geomagnetic coordinates are calculated in the simple shifted-tilted dipole model.
