AB: During the geomagnetic storm of October/November 2003, the intensity peak of the outer radiation belt electron moved from its nominal position of L=4 to L=2.5 within a day. This event was correlated with extremely high solar wind speeds and enhanced ULF wave power throughout the inner magnetosphere, both are known to be associated with enhanced radial transport of radiation belt electrons. A modeling effort was made, using the measurements of relativistic electrons at geosynchronous orbit as the source population and solar wind parameters as input to a radial diffusion coefficient. We found that the deep penetration of MeV electrons down to L=2.5 could be mostly explained by the fast inward radial transport mechanism.
