Magnetic Substorms From Ground And Space (4/11/2008)

One of the most dynamic events in the interaction between the Sun and the Earth is a 'substorm', an explosive reshaping of the Earth's outer magnetic field. To better understand substorms, scientists in Europe and North America are studying them from space using the Time History of Events and Macroscale Interactions during Substorms (THEMIS) satellites launched by NASA in 2007 and from the ground using a network of all-sky cameras. ...> Full Article
