Sun-Earth Day 2008: Space Weather Around the World

IMAGE GALLERY

An aurora from the ground at Yellowknife, NT in December 2004. Without magnetic storms, aurora would be featureless glows in the sky. Magnetic fields provide the pathways for currents to flow into the atmosphere in particular patterns controlled by the magnetic forces and their changes through time. (Courtesy: Andrew Eaton)
