Flare star
A flare star is a variable star which can undergo unpredictable dramatic increases in brightness for a few minutes or a few hours. The brightness increase is across the spectrum, from X rays to radio waves.
Flare star A flare star is a type of star which regularly experiences brief, random outbursts of solar flares over its surface disrupting energy patterns in its system and sometimes endangering lifeforms.
FLARES
The most spectacular phenomenon related to sunspot activity is the solar flare, which is an abrupt release of magnetic energy from the sunspot region.

A powerful explosion of particles and energy known as a solar flare erupts from the Sun in this false-color image. The flare forms a bright red loop at lower left.
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.

Iridium Flares
What are Iridium Flares?
Iridium flares are spectacular, bright reflections from satellites in low Earth orbit.
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.
"Although the flare was a moderate one, it still released an immense amount of energy," said Dr. Craig Deforest, a researcher with the SOHO project.

Solar Flare Sparks Biggest Eruption Ever Seen on Sun

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 flare An enormous explosion of gas in the solar atmosphere resulting in a sudden burst of particle acceleration, the heating of plasma and the eruption of large amounts of solar mass. This image of a solar flare is courtesy of NASA JSC.
Solar flares are an example of explosion common on the Sun, and presumably on most other stars as well.
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.
SOLAR FLARE
A solar flare is a magnetic storm on the sun, which appears to be a very bright spot, and a gaseous surface eruption. Solar flares are classified based upon their x-ray energy output at peak burst intensity.

Activity 5-Flares on the Sun
When magnetic fields on the Sun intertwine, the resulting sunspots look very different from a classical bipolar sunspot.
flare (NASA SP-7, 1965) 1. A bright eruption form the sun's chromosphere. Compare prominence.
Flares may appear within minutes and fade within an hour.
Solar flares are much more violent eruptions. They will emit strong X-ray, ultraviolet, visible light and solar wind.
Being so faint, flare stars must be very close to the solar system to be noticed; indeed many of them are within fifteen light years from us. UV Ceti is 8.4 light years away.
