International Heliophysical Year (IHY)

The IHY had three primary objectives:

• Advancing our Understanding of the Fundamental Heliophysical Processes that Govern the Sun, Earth and Heliosphere
• Continuing the tradition of international research and advancing the legacy on the 50th anniversary of the International Geophysical Year
• Demonstrating the Beauty, Relevance and Significance of Space and Earth Science to the World

IHY has officially closed as of March 2009. Many aspects of IHY are being continued through the International Space Weather Initiative (ISWI).
