Solar storm

A solar storm is a disturbance on the Sun, which can emanate outward across the heliosphere, affecting the entire Solar System, including Earth and its magnetosphere, and is the cause of space weather in the short-term with long-term patterns comprising space climate.


Solar storms include:

  • Solar flare, a large explosion in the Sun's atmosphere. Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots.
  • Coronal mass ejection (CME), a massive burst of solar wind, sometimes associated with solar flares
    • Coronal cloud, the mass of plasma and particles ejecta of a CME after jettisoned from the Sun
  • Geomagnetic storm, the interaction of the Sun's outburst with Earth's magnetic field
  • Solar particle event (SPE), proton or energetic particle (SEP) storm

  • Magnetic cloud, a transient disturbance in the solar wind
  • Solar cycle, an 11-year cycle of sunspot activity
  • Solar prominence, and solar filament, a large loop-shaped eruption of the sun that can also lead to CMEs (often in concert with a flare)
  • Solar wind, the stream of particles and plasma emanating from the Sun
  • Sunspot, where most solar flares and coronal mass ejections originate (technically, a region of sunspots)
