Solar storms increasing through 2013
For thousands of years people have been watching the sun. With the invention of the telescope, scientists have been recording the number of spots they see forming on the sun's surface. Sunspots are believed to be the source of solar storms.
According to Matt Penn, an associate astronomer at the National Solar Observatory located here in Tucson, "On the Sun we have sunspots with huge magnetic fields and they're the source of two things that effect us on Earth…Solar flares and also Coronal Mass Ejections. So a Solar flare happens when the magnetic field within these sunspots changes and erupts with light and particles, a CME, a coronal mass ejection happens when an enormous amount of mass is thrown off from again a change in a magnetic field of a sunspot."
Not all solar storms effect the Earth. Many times this matter is hurled into space and never encounters the Earth. The Earth is exposed to solar flares and CMEs from time to time, causing some dramatic effects.
