It was an extraordinarily intense white light flare, a flare emitting a high amount of light in the visual spectrum. Since flares produce copious amounts of radiation at H-alpha, [citation needed] adding a narrow ... See more A solar flare is an intense localized eruption of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, … See more Soft X-ray classification The modern classification system for solar flares uses the letters A, B, C, M, or X, according to the peak See more Flares produce radiation across the electromagnetic spectrum, although with different intensity. They are not very intense in visible … See more Solar flares affect all layers of the solar atmosphere (photosphere, chromosphere, and corona). The plasma medium is heated to tens of millions of kelvins, while electrons See more Flares occur when accelerated charged particles, mainly electrons, interact with the plasma medium. Evidence suggests that the phenomenon of magnetic reconnection leads … See more Terrestrial Normal everyday levels of X-rays and extreme ultraviolet radiation emitted by solar flares are absorbed by the daylight side of Earth's atmosphere and do not reach the Earth's surface.
