What is solar flare? A solar flare is a sudden, intense burst of radiation from the Sun's surface. It is caused by the release of magnetic energy stored in the Sun's atmosphere, specifically in the corona, which is the outermost layer of the Sun's atmosphere. Solar flares are classified into different groups based on their strength, with the largest flares being referred to as "X-class" flares. They can last anywhere from a few minutes to several hours and can release a tremendous amount of energy, equal to millions of atomic bombs. Solar flares are accompanied by a coronal mass ejection (CME), which is a large burst of plasma and magnetic field that is released into space. CMEs can interact with the Earth's magnetic field and cause geomagnetic storms, which can affect our technology, such as communication systems, GPS signals, and electrical power grids. Solar flares and CMEs are an important area of study for scientists, as they can provide insight int...
