KB QuickTime simulation of a CME impact on Earth's magnetosphere.
With the sun offscreen to the left,
the earth's magnetosphere is visualized as a series of translucent blue shells that depict
the magnetic fields at 60, 75, and 85 degrees from the equator. The electrically
charged CME travels through the magnetosphere in roughly one hour, compressing the
magnetic field lines and inducing a buildup in the earth's auroras. After the CME
passes, the field lines quickly return to their original configuration and the auroras
return to their pre-impact energy levels. For visual clarity, this simulation shows
the auroral increase peaking well after the CME passes.
