Presents an overview of recent research on the original of solar phenomena that affect Earth s technological systems.

This topical issue is based on the presentations given at the 26th National Solar Observatory (NSO) Summer Workshop held at the National Solar Observatory/Sacramento Peak, New Mexico, USA from 30 April to 4 May 2012. This unique forum brought together experts in different areas of solar and space physics to help in developing a full picture of the origin of solar phenomena that affect Earth s technological systems. The articles include theory, model and observation research on the origin of the solar activity and its cycle, as well as a discussion on how to incorporate the research into space-weather forecasting tools.

This volumeis aimed at graduate students and researchers active in solar physics and space science.
