Impulsive Phase Transport. Chapter 3,

Abstract

The collective body of evidence derived from hard X ray, gamma ray, ultraviolet, microwave, and visible light observations of the impulsive phase of solar flares is reviewed and reexamined within the context of models for energy release and energy transport. Strong support is found for energy transport by non thermal electrons accelerated in the solar corona. These electrons can be shown to be adequate in providing energy to the hard X ray and microwave bursts, but they have difficulty in explaining the optical emission originating from the deep chromosphere; in addition, gamma ray bursts seem to require high-energy protons. It is concluded that our understanding of the impulsive phase is less than satisfactory.
