To burn with an unsteady or waving flame; as, the candle flares.
To shine out with a sudden and unsteady light; to emit a dazzling or painfully bright light.
An unsteady, broad, offensive light.
A sudden worsening of disease or pain.
An explosion on the Sun usually releasing large amounts of energy and particles, and usually occurring within an active region. Flares are more likely at solar maximum.
A sudden eruption in the vicinity of a sunspot, lasting minutes to hours, caused by the release of large amounts of magnetic energy in small volume above the solar surface. ( go to first use in the text)
brief magnetic--induced explosion on the surface of the Sun.
Sudden energetic eruption of radiation in the Sun's chromosphere.
A firework that creates a bright light, normally for some time. These can vary from Bengal Flares which are ground based and create an intense flame (as opposed to a shower of sparks which is a fountain), to rocket launched effects. An "aerial" flare effect is just a star that burns brightly and for a long time. Distress flares, which are not fireworks, use a parachute to ensure the flare stays airborne for some time.
Explosive event occurring in or near an active region on the Sun.
A sudden, immense outburst of energy and mass from the Sun. Within a time measured in seconds or minutes, typical flares release energies of several tens of thousands of megatons of TNT. Large flares can release energies hundreds of thousands of times greater than that.
An explosion on the sun that releases large amounts of energy and particles. Typically a flare occurs within an active region. Flares are more likely to occur at a solar maximum.
a sudden burst of flame
a sudden recurrence or worsening of symptoms; "a colitis flare"; "infection can cause a lupus flare"
a sudden eruption of intense high-energy radiation from the sun's surface; associated with sunspots and radio interference
a sudden outburst of emotion; "she felt a flare of delight"; "she could not control her flare of rage"
shine with a sudden light; "The night sky flared with the massive bombardment"
erupt or intensify suddenly; "Unrest erupted in the country"; "Tempers flared at the meeting"; "The crowd irrupted into a burst of patriotism"
a brilliant outbreak in the Sun's upper atmosphere at or near a sunspot
a giant explosion in the solar atmosphere that spews radiation and results in the heating of solar gas and the acceleration of particles to nearly the speed of light
an enormous explosion on the surface of a star, which is accompanied by a release of magnetic energy
a sudden change of disease activity, for example, the development of new symptoms
a type of pyrotechnic that produces a brilliant light or intense heat without an explosion
a type of pyrotechnic that produces a long-durationbrilliant light without an explosion
see solar flare
A bright eruption from the sunâ€™s chromosphere. Flares may appear within minutes and fade within an hour. They cover a wide range of intensity and size, and they tend to occur between sunspots or over their penumbrae.
a pyrotechnic device used for attracting attention or indicating distress
A rapid eruption of material from the surface of the sun or other star. A to F | G to L | M to R | S to Z
A sudden release of energy in the solar atmosphere, lasting from minutes to hours, from which radiation and particles are emitted.
A sudden reaction to starting hormone therapy, sometimes characterized by severe increase in pre-hormone therapy symptoms, such as pain; does not occur in all men; some report it may be prevented by taking an anti-androgen (Casodex, Nilandron) several days before starting hormone therapy.
A sudden and temporary outburst of light from an extended region of the Sun's surface.
A violent eruption on the Sun's surface (chromosphere), accompanied by emissions of protons and other particles and of electromagnetic radiation.
(Solar) Rapid release of energy from a localized region on the Sun in the form of electromagnetic radiation, energetic particles, and mass motions. more
The sudden brightening of a meteor, most commonly near the end of its path when it is referred to as a Terminal Flare.
A sudden outburst of energy from the Sun that occurs near concentrated magnetic fields (known as active regions) on the Sun’s visible surface. Flares emit high-energy charged particles (ions and electrons) and all forms of electromagnetic radiation into space.
(or "solar flare")--an rapid outburst on the Sun, usually in the vicinity of active sunspots. A sudden brightening (usually seen only through special filters) may be followed by the signatures of particle acceleration to high energies--x-rays, radio noise and often, a bit later, the arrival of high-energy ions from the Sun.
A sudden eruption of energy on the solar disk lasting minutes to hours, from which radiation and particles are emitted.
Violent solar activity often observed in the vicinity of a sunspot or prominence, and which releases pent-up energy in the form of electromagnetic radiation and huge quantities of charged particles.
Rapid release of large amounts of energy from a small region on the Sun in the form of electromagnetic radiation and energetic particles. The Sun unleashed a powerful flare on 4 November 2003 that could be the most powerful ever witnessed and probably as strong as anything detected since satellites were able to record these events in the mid-1970s.
A sudden and violent outburst of solar energy that is often observed in the vicinity of a sunspot or solar prominence; also known as a solar flare.
A bright, transient event within the sun's chromosphere and corona. Flares produce enhanced emission at radio frequencies and in the ultraviolet and x-ray spectral regions as well. They may also produce increased particle emission, often with ions of cosmic ray energies. Flares usually appear within minutes and fade within an hour. They are localized to small areas (typically 10âˆ’3 of the solar disk) and usually occur within solar active regions.
Flares are created in the active regions of the Sun by a sudden release of energy. This accelerates charges particles in the region which, in turn, causes radiation to be emitted across the whole spectrum from X-rays to radio waves. Particles are also ejected from the Sun and travel through the Solar System. These cause magnetic disturbances on the Earth. This can cause blackouts and loss of quality in radio communications and aurorae. If the blast of radiation from the flare is poerful enough, it can cause systems failures in spacecraft and has been know to shut down regional power systems on the surface.
