Much can be said about the Sun. There is no doubt that the sun - the source of life. That gave life, and it may take. It happens. Can our Sun to be dangerous for us in the foreseeable future?
The sun has a magnetic field. The interaction of the substance of the plasma and the local magnetic fields and gives rise to the phenomenon known as solar activity. This is - sunspots, flares, solar wind disturbances. Solar flare - an explosive process, which results in the release of enormous energy in the atmosphere of the Sun - and light, and thermal and kinetic - billions of megatons.
Classification of solar flares.
The accepted classification of solar flares based on the intensity of the peak X-ray radiation (W / m 2 ) categories of outbreaks identified in the Latin alphabet: A, B, C, M, X. Each of the following letter indicates the increase in power of ten. Outbreaks of category X - the most powerful, characterized by the intensity of the peak (W / m 2 ) greater than 10 -4 . This category flashes can explicitly influence what happens on planet Earth.
Flash creates a wave solar radiation, which travels at the speed of light and reaches the Earth in 8 minutes. This is - in the range of electromagnetic radiation from radio to X-rays. But more powerful flash is accompanied by a coronal mass ejection, and that if the fly in the "right" direction to reach Earth in about 4 days. This is - a stream of particles: protons, electrons, and a certain amount of heavier elements: iron, helium, oxygen.
