This is an exhaustive survey of present-day solar research including both theory and observations. It deals with eruptive flares, filament eruption in x-rays and radio waves, energy release and transport, and terrestrial response to solar flares. Details of the most recent SOLAR-A project (launched shortly after the conference) are also presented.

This complete survey of theoretical research and observations of solar activities and the terrestrial response to eruptive solar flares addresses astronomers, astrophysicists and space-science-researchers.
