Explosive Solar Activity
All these increase and decrease with the
11 year cycle in the Sun's magnetic field, and can occur together
Active Region or Sunspot Region
- Area of enhanced magnetic field on the Sun's surface.
- Intense brightening near the solar surface. Visible in almost all wavelengths of light.
Coronal Mass Ejection (CME)
- A magnetic bubble of gas that erupts from the Sun,
spreading out into space at over a million km/hour.
- A magnetically supported structure of relatively cool gas
as compared to the surrounding corona. They can erupt and often
do so with CMEs.
