Recent observations have shown the existence of an apparent impenetrable barrier
at the inner edge of the ultra-relativistic outer electron radiation belt. This
apparent impenetrable barrier has not been explained. However, recent studies
have suggested that fast loss, such as associated with scattering into the
atmosphere from man-made very-low frequency transmissions, is required to limit
the Earthward extent of the belt. Here we show that the steep flux gradient at
the implied barrier location is instead explained as a natural consequence of
ultra-low frequency wave radial diffusion. Contrary to earlier claims, sharp
boundaries in fast loss processes at the barrier are not needed. Moreover, we
show that penetration to the barrier can occur on the timescale of days rather
than years as previously reported, with the Earthward extent of the belt being
limited by the finite duration of strong solar wind driving, which can encompass
only a single geomagnetic storm.
