- Solar Flares. A solar flare is an enormous explosion in the solar atmosphere. It results in sudden bursts of particle acceleration, heating of plasma to tens of millions of degrees, and the eruption of large amounts of solar mass.

Solar wind The solar wind is a stream of charged particles released from the upper atmosphere of the Sun. This plasma consists of mostly electrons, protons and alpha particles with energies usually between 1.5 and 10 keV; embedded in the solar-wind plasma is the interplanetary magnetic field.

Flare (countermeasure) Flare (countermeasure) A flare or decoy flare is an aerial infrared countermeasure used by a plane or helicopter to counter an infrared homing (heat-seeking) surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter than engine exhaust.

Solar flare eruptions set to reach Earth These coronal mass ejections will slam into the Earth's magnetic shield. The waves of charged solar particles are the result of three solar flares directed at Earth in recent days, including the most powerful since 2006. The biggest flares can disrupt technology, including power grids, communications systems and satellites.

Definition of Sunspot Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere. Sunspots usually appear in pairs, with pair members of opposite magnetic polarity.

The Effects of Solar Winds on Satellites Enormous explosions called solar flares happen at these borders. Solar flares shoot streams of high-energy, charged particles -- or plasma -- out into space. This plasma is called the solar wind. Solar wind that reaches Earth's orbit can interfere with communications and electrical equipment, including satellites.

- This loop is called a solar prominence and such features appear because of the magnetic field of the Sun. Sunspots are also responsible for bright bursts from the surface called solar flares and the more there are, the brighter the Sun appears!

What is a Solar Flare? Soft x-ray image of a solar flare on the Sun. As the magnetic energy is being released, particles, including electrons, protons, and heavy nuclei, are heated and accelerated in the solar atmosphere. The energy released during a flare is typically on the order of 1027 ergs per second. Large flares can emit up to 1032 ergs of energy.

Solar Storms ○ Solar Prominences: are arcs of cooler gas that erupt. from the Sun's surface, extending hundreds of thousands of. miles into space and are held in place by the Sun's strong. magnetic field; they can last for months. ○ Solar Flares: are bright, super hot gaseous eruptions. that are ejected thousands of miles into space, usually found.

- The key to understanding and predicting solar flares is the structure of the magnetic field around sunspots. If this structure becomes twisted and sheared then magnetic field lines can cross and reconnect with the explosive release of energy.

The Effects of Solar Winds on Satellites Sudden Storms. Two types of solar flares cause sudden upheavals in the solar wind by giving it greater speed, density or temperature. Coronal hole high-speed streams produce a steady stream of solar wind flowing from whirlpool-like collisions on the sun's surface.

Solar Flares A solar flare can be sufficiently strong that it disrupts the magnetic field of the surrounding active region setting up oscillations in neighboring loops. These dynamical signatures help scientists determine the physics of what is going on during a solar flare.

- Both flares and CMEs depend on magnetic fields on the Sun. Image Credit: SOHO Image Credit: TRACE The most obvious difference between a solar flare and a CME is the spatial scale on which they occur. Flares are local events as compared to CMEs which are much larger eruptions of the corona.

- Solar Maximum. During a 'solar max' sunspot activity is heightened offering more chances to see the northern lights. Sunspots are dark, cool areas of the sun's surface which erupt causing the sun to fire out its solar flares or charged particles-the catalysts for the northern lights.

Solar flares: everything you need to know A flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released - mostly in the active regions around sunspots. Their frequency varies from several a day, when the sun is particularly active, to less than one a week during quiet periods. Large flares are less frequent than smaller ones.

What is radiation therapy? Radiation therapy is a cancer treatment that uses concentrated radiation beams to kill cancer cells. The most common type of radiation therapy is external beam radiation. This type involves a machine that directs high-energy beams of radiation at cancer cells.

Solar flares: everything you need to know A flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released - mostly in the active regions around sunspots. Their frequency varies from several a day, when the sun is particularly active, to less than one a week during quiet periods. Large flares are less frequent than smaller ones. Solar activity varies within an 11-year cycle at the peak of which there are typically more sunspots and therefore more solar flares.

Solar flares: everything you need to know What is a solar flare? A solar flare is a large explosion of magnetic energy in the Sun’s atmosphere which causes an intense burst of increased brightness. They cannot be detected by the naked eye from the surface of the earth but can be observed through telescopes, space x-rays and thermal imaging equipment.

How does a solar flare form? Answers.com® is making the world better one answer at a time. solar flares are caused by the periodic entangling and untangling of the sun's magnetic field. occasionally a field line becomes twisted to the point it tries to snap back into place, in doing so it can throw out a little solar material, a solar flare.

Space Weather: Sunspots, Solar Flares & Coronal Mass Ejections The magnetic field lines that twist up to form solar flares occasionally become so warped that, like rubber bands under tension, they snap and break, then reconnect at other points. The gaps that form no longer hold the sun's plasma on its surface. Freed, the plasma explodes into space as a coronal mass ejection (CME). [ Stunning Photos of Solar Flares & Sun Storms ]. It takes several hours for the CME to detach itself from the sun, but once it does, it races away at speeds of up to 1,000 km (more than 7 million miles per hour).

Solar Flares Can Affect Communications and Power Grid On the plus side, the solar flares from this sunspot reached their peak in 2013 and are now subsiding. Solar flares can indeed affect communications and power grids as well as satellites and the attendant GPS signals, but for now it seems these systems have escaped the worst ravages of the solar storm. By Kat Turner.

What Would Happen if a Massive Solar Storm Hit the Earth? Despite observing flares for over a century, scientists still aren’t totally sure what causes the Sun to erupt. We do know that flares have a lot to do with disruptions in the Sun’s powerful magnetic field, which oscillates over the course of an 11-ish year solar cycle.
