This large solar flare, produced by an active region of the sun (AR9077), triggered magnetic storms and knocked out satellites when it created a solar storm on July 14, 2000.
Images of the sun in the far ultraviolet and in X-rays (acquired most recently by the Solar and Heliospheric Observatory spacecraft, the Yohkoh satellite, and the NIXT rockets) show that the heating of the corona is localized in solar active regions, which indicates the important role played by the magnetic field.
The day of the failed eruption, scientists pointed the VAULT2.0 sounding rocket — a sub-orbital rocket that flies for some 20 minutes, collecting data from above Earth's atmosphere for about five of those minutes — at an area of intense, complex magnetic activity on the Sun, called an active region.
Active regions on the solar surface, often the sources of solar flares, may form in areas where flows converge, causing magnetic fields to become concentrated.
Evolution of the magnetic field in two simulations of the formation of active solar regions.
Fine details of a magnetic flux rope captured by the New Solar Telescope at Big Bear Solar Observatory for Solar Active Region 11817 on 2013 August 11.
After accounting for the deflection of the cosmic rays by the Milky Way's magnetic field, the team found that the particles are travelling about 326 million light years from a region of extragalactic space containing several potential sources, such as active galactic nuclei and starburst galaxies.
Around active regions of the star's atmosphere, magnetic fields become twisted and distorted.
The top candidates, the astronomers suggested, are a neutron star, possibly a highly - magnetic magnetar, surrounded by either material ejected by a supernova explosion or material ejected by a resulting pulsar, or an active nucleus in the galaxy, with radio emission coming from jets of material emitted from the region surrounding a supermassive black hole.
Based on these observations and experiments, Harker and Pevtsov conclude that the observed magnetic transient is not an artifact created by the SDO / HMI observation process, but instead represents a real change in the vector magnetic field; since the active region was located so close to the solar limb, this suggests that the transient manifested in the horizontal component of the magnetic field (relative to the solar surface).
Although it is well established that the Sun's magnetic field is responsible for the supply of energy to the atmosphere, exactly how this magnetic energy is converted into thermal energy is still not understood in detail, as models struggle to simultaneously encompass the very disparate temporal and spatial scales on which the heating has to occur, in different structures, with a wide variety of characteristics (e.g. open versus closed structures, short quiet - sun loops versus hot active - region loops and large - scale interconnecting loops).
While the bright active regions have long been known to be sources of heating, the diffuse heating appears to be associated with the ubiquitous magnetic carpet.

Loops of plasma are held in place by the sun's strong magnetic fields, concentrated in active regions that are visible to the naked eye as sunspots.
After its birth some 4.6 billion years ago, the Sun had an extremely active magnetic field during its infancy, with gigantic dark star - or Sun - spots that sometimes covered its polar regions.
The high magnetic fields in the sunspot - producing active regions also give rise to explosions known as solar flares.
Magnetic Island is ideal for leisurely relaxation or more active pursuits, the easy accesibility and region's fantastic weather makes this the ideal destination to explore all year round.
