Tiivistelmä
We consider the time-profile morphology of solar high-energy particle emissions, including relativistic electrons in three energy channels of SOHO/EPHIN, relativistic protons as registered by the worldwide network of neutron monitors, and 100 MeV/n protons and helium in several
energy channels of SOHO/ERNE. Based on numerical modeling of the interplanetary transport,
we formulate a simple method for investigation of the high-energy particle sources operating at /
near the Sun during the first hour of particle event. The method is applied to Ground Level Enhancement (GLE) and Solar Energetic Particle (SEP) events of the solar cycle 23. We conclude that depending on the GLE-SEP event scenario and detector vantage point, the observed particles originate from at least three sources. Possible nature of the sources is discussed in the framework of previous and new models of the high-energy particle production associated with global coronal (EIT) waves and CME shocks within about five solar radii from the Sun.
