The Global Interplanetary Shock Scenario

In this paper we explore the nature of that 18% or less of all interplanetary coronal mass ejecta driven shocks that have the power to accelerate solar wind or other seed particle populations to energies hundreds or thousands of times that of the solar wind ion plasma. Interesting findings will be presented and discussed for specific cases when the shock passage was observed at multiple spacecraft locations separated by tens of degrees in heliospheric longitude and in most cases within 1 AU of the Sun.
