Solar Flare
Solar flares are sudden blasts of electromagnetic radiation and charged particles emanating from the surface of the Sun. They are distinct from the everyday solar wind due their association with highly energetic eruptions.

Solar Flares:
A solar flare is a sudden intense brightening of a small part of the Sun's chromosphere in the vicinity of a plage or facula and often near a sunspot group. The flare develops in a few minutes and may last several hours.

Solar flares were first observed by in 1859 by Lord Richard C. Carrington. He wrote that as he was watching the sun with a telescope, he saw "two patches of intensely bright and white light" near a huge group of sunspots.
A solar flare is a spontaneous release of energy on the Sun's surface. The Sun's surface contains large magnetic loops. These loops, solar prominences, occasionally collide and short-circuit each other. This is what causes solar flares.

Solar flares are areas around sunspots that brighten sharply when seen through a telescope because of an enormous energy release. One of the main characteristics that distinguishes solar flares from other solar events is how suddenly they occur.

Solar Flare Sparks Biggest Eruption Ever Seen on Sun
National Geographic - June 8, 2011
A solar blast that NASA classified as an M-2 explosion erupted from the sun in an impressive display captured by the space agency's cameras.
Solar flares. Referred to as a solar flare, an ordinary one of these eruptions can belch a billion tons of the Sun's atmosphere out across space at a million miles per hour.
Solar flares are an example of explosion common on the Sun, and presumably on most other stars as well.
Solar Flares
During periods of high solar activity, the Sun commonly releases massive amounts of gas and plasma into its atmosphere. These ejections are known as solar flares. Some solar flares can be truly massive, and contain impressive power.
solar flare An outburst caused by the sudden release of energy that heats and accelerates matter in the solar atmosphere, and produces a sudden brightening over a wide range of wavelengths.
Solar flares are eruptions more powerful than surge prominences (a flare is shown in the Sun + planets montage above). They will last only a few minutes to a few hours. A lot of ionized material is ejected in a flare.

The most spectacular phenomenon related to sunspot activity is the solar flare, which is an abrupt release of magnetic energy from the sunspot region.
When there are many sunspots visible on the surface of the Sun (at the time of solar maximum), other features such as solar flares and prominences are also visible.
One correlation that is definitely established, and also better understood, is that between solar flares and geomagnetic activity at Earth.
