Solar Flares

A solar flare is a sudden brightening observed over the sun’s surface or the solar limbs. It’s flare ejects clouds of electrons, ions, and atoms through the corona of the sun into space. It affects all layers of the solar atmosphere, when the plasma medium heats up to tens of millions of kelvins the electrons, protons, and heavier ions accelerate to near the speed of light. Flares occur in active regions such as sunspots. They are powered by the sudden release of magnetic energy stored in the corona. The flares occur when accelerated charged particles, electrons, interact to the plasma medium. The phenomenon of magnetic reconnection is responsible for the acceleration of charged particles. The flares erupt when the active regions on the sun, which magnetic fields are much stronger on average. The solar flares can produce streams of highly energetic particles in the solar wind known as Coronal Mass Ejection. These particles do impact the Earth’s magnetosphere, and it causes radiation hazards to spacecraft, and astronauts.
