The solar flares represent explosions at the surface of the sun. The solar flares are produced almost every day and they usually affect all layers of the sun’s atmosphere. The large ones release huge amounts of energy and could even eject coronal mass into the space. The solar flares also produce different types of radiation that also burst into the space.

The UV and X-ray radiation produced by large solar flares can reach the Earth affecting the upper layer of the atmosphere called ionosphere. These two types of radiation can disrupt long-range radio communications and radars that have the same wavelengths. (more…)
