Since the dawn of time, mankind has perceived the Sun's influence on our life on Earth. However, in recent decades, with the widespread use of technology and electricity in all our activities, our society has become increasingly closely exposed and vulnerable to bursts of solar activity. Today, more than ever before, the Sun interferes with every aspect of our daily lives, including major societal issues such as energy and climate change.

This conference will provide an opportunity to review the impressive phenomena of solar activity and their short- and long-term impact on our terrestrial environment: solar flares, coronal mass ejections, particle storms. All this magnetic activity originates inside the Sun, and is marked by an 11-year cycle that has varied considerably over the centuries. We'll be taking stock of our current understanding of this cyclical phenomenon, which turns out to be a genuine magnetic recycling process.

As we pass through a peak in solar activity today, this will be an opportunity to look ahead to the future and the central role the Sun can play as a source of multiple energies to build a viable future for mankind. For us, the future will inevitably involve the Sun!
