SUMMARY: The European Space Agency's Cluster spacecraft were perfectly positioned to watch the effect of the recent solar storms on the Earth's magnetosphere. Normally the magnetosphere bubbles out in front of the Earth by about 64,000 km, but during the storm it was down to only 43,000 km. The speed at which the magnetosphere compressed will help scientists calculate the power of the storm, and make more accurate predictions for what will happen in future storms.
