The Observational Aspects of the Three Largest Solar-Energetic Particle Fluxes:19-20/10/1989,14/7/2000 and 9/11/2000

摘要

The study of the largest solar energetic particle (SEP) events gives important information about the physical process in the solar corona and in the heliosphere.The hourly solar energetic particles and interplanetary (IP) and geomagnetic measurements of the three largest SEP events have been compared.The results indicate that there is a quite different in IP and geomagnetic disturbances and in turn,the mechanism of particle accelerations among the three events.The acceleration of fluxes was not a function of the IP shock's efficiency.The IP shock was hardly deteriorated in its path to the Earth.Different dynamics structures in the heliosphere during the considered events,have been found.
