ocr: Animation of CME impact on the Earth's magnetosphere based on real data. The color of the solar wind gusts reflects the density where darker red means higher density. One can see how the 50- lar wind gusts push the magneto- sphere towards the Earth and causing violent disturbances and spectacular auroral displays. The blue circle shows the aurora as seen from above the North Pole. Credits: Space Plasma Physics, Univ. of Maryland
