Reports of the Working Groups: WORKING GROUP C, PROPAGATION OF EVENTS IN PROGRESS

摘要

The focus of Working Group C was on understanding the propagation and evolution of solar energetic particles. SEPs are a potentially serious risk to humans and their sensitive instruments when they journey beyond Earth's protective magnetosphere to reach the Moon and other locations called for in the Vision for Space Exploration. From a science standpoint, it is important to understand the variability and extreme values for properties of SEP events in order to develop a predictive capability that could eventually be incorporated into an operational space weather warning system. The science community recognizes that an accurate and reliable warning system requires a better understanding of the physical processes that produce SEP events. A firm foundation for such a system requires the development of physical models for particle production, acceleration, and transport. These models should be validated by appropriate observations before they are transitioned to operational use.
