  Where did all the electrons go?

  Geomagnetic storms driven by the solar wind can cause the flux of high-energy electrons in the Earth's Van Allen belts to rapidly fall. Analysis of data obtained during one such event from multiple spacecraft located at different altitudes in the magnetosphere reveals just where these electrons go.

  Explaining sudden losses of outer radiation belt electrons during geomagnetic storms

  Geomagnetic storms driven by the solar wind can cause a dramatic drop in the flux of high-energy electrons in the Earth’s outer Van Allen belt. Analysis of data obtained during such an event by three different sets of spacecraft suggests that these electrons are directed into space rather than lost to the atmosphere.
