AB:
An interplanetary shock was clearly registered by both ACE and Geotail
on Nov. 7, 2004, impacting on the Earth's magnetopause around 18:25 UT. Soon
afterwords, great enhancements of relativistic electrons in the inner
magnetosphere were measured by CLUSTER, Polar, SAMPEX, HEO, and GPS. The
interplanetary shock was certainly associated with these electron enhancements.
A fast inward radial transport due to the shock-induced electric field is a
viable mechanism. However, there was no continuous measurement of the electrons
near the equatorial region in the inner magnetosphere. The exact cause and detailed physical processes leading
to the observed enhancements is still to be determined.
Nonetheless, this is a very interesting event.
