A terrestrial gamma-ray flash (TGF) event with associated electron/positron beams which were detected by the fermi telescope as well as its bounce from the magnetic mirror point[1]
In astrophysics, a magnetic mirror point is a point where the motion of a charged particle trapped in a magnetic field (such as the (approximately) dipole field of the Earth) reverses its direction. More precisely, it is the point where the projection of the particle's velocity vector in the direction of the field vector is equal to zero.
