This book comprises an excursion through space weather, a scientific topic in rapid growth and with growing impact and complications for technological societies.

The emphasis of the present volume is on the origins of space weather: the Sun and the solar mind. Very much as the Sun`s electromagnetic radiation drives the Earth climate, our space weather is driven by the solar wind.

This book addresses students and scientists working, or interested in, the field and provides a thorough introduction to the topic for those who wish to become acquainted with the basic solar physics at the origin of space weather.
