Solar Storms</B>
  • There are two kinds of solar storms: coronal mass ejections (CMEs) and solar flares. A flare occurs when magnetic energy builds to a peak near the Sun's surface and explodes. This intense, fast-paced event sends high-energy particles into space. A much larger storm, a CME erupts when magnetic field lines snap, sending billions of tons of particles into space at millions of miles per hour. The particle cloud expands to over 30 million miles by the time it reaches Earth.
Impact From Space
  • When the particles ejected from the Sun interact with the Earth's own protective magnetic shield, its magnetosphere, the impact can be observed as aurora. Gases in the upper atmosphere become excited and glow. These are most commonly seen near the Earth's polar regions where the magnetic field lines guide the charged energy toward Earth. If viewed from high above Earth, they appear as ovals. Images taken by astronauts in the space shuttles show the depth of aurora. Other impacts from this energy pouring into the Earth's atmosphere, include short-circuiting power grids that cause blackouts, disrupting communications, damaging satellites, and endangering astronauts with radiation.
