Coronal Mass Ejection

Posted on the 26 March 2011 by Gabe12logan
During the eruptions on the sun happens the so-called "coronal mass ejection", when electrically charged particles ejected from the sunny spots in height. Then solar winds form which releases a huge amount of energy, on Earth seen as a particularly intense "polar light".
Solar coronal mass ejection (CME) is a massive explosive event, which ejects plasma, or solar wind or open single-pole magnetic fields ejects plasma from the corona into space. Coronal mass ejection is often associated with other solar activities, mainly with solar flares. Most of them come from active regions of the solar surface, where the sunspots are associated with solar flares during solar maximum, but can also occur during the solar minimum.
Coronal Mass Ejection
When solar winds arrive near the Earth they crash into the magnetic field and they can cause geomagnetic storms. Charged particles in the field turning and follow his lines toward the planet poles. They collide in atmosphere with atoms of nitrogen and oxygen and create a miniature neon lights.
Coronal mass ejection is certainly a most violent physical process in the whole solar system.
