A Solar flare is a sudden flash, probably a bright light, on the Sun’s surface. If this sudden flash of brightness is seen on a star beside the\u00a0Sun, the phenomenon is termed as a stellar flare. A vast amount of energy is released from a stellar or solar flare, typically on the order of\u00a01 \u00d7 1025\u00a0joules, over a broad spectrum of\u00a0wavelengths\u00a0and particles. This massive amount of energy is comparable to the explosion of 1 billion megatons of TNT or ten million volcanic eruptions. A solar flare may eject atoms, electrons, and ions into space in what is called a coronal mass ejection, in addition to light. When the Sun releases particles, these particles reach Earth within a day or two. Fortunately, the mass may be ejected outward in any direction, so our planet is not affected always. Unfortunately, scientists are unable to forecast solar or stellar flares, only give a warning when one has occurred.<\/strong><\/p>\n\n\n\n

Like planets, stars consist of multiple layers. In\nthe case of a solar or stellar flare<\/strong>, all layers of the Sun’s atmosphere\nare affected. Let\u2019s understand this is in simple terms \u2013 energy is released\nfrom the photosphere, chromosphere, and corona. Flares tend to occur in\nregions of intense magnetic fields. These magnetic fields connect the\natmosphere of the Sun to its interior. Flares are believed to be the result of\na process called magnetic reconnection where loops of magnetic force break\napart, rejoin and release energy. When magnetic energy<\/strong> is, all of a\nsudden, released by the corona, light and other space particles are accelerated\ninto space. <\/p>\n\n\n\n

The released matter\u2019s source seems to be material\nfrom the unconnected helical magnetic field. However, scientists have not\ncompletely worked out how flares work and why there are sometimes more released\nparticles than the amount within a coronal loop. <\/p>\n\n\n\n

The ions, protons, and electrons gain velocity due to the intense energy to nearly the speed of light.\u00a0From gamma rays to radio waves, electromagnetic radiation<\/strong>\u00a0covers the entire spectrum. The released energy in the visible part of the spectrum makes some flares observable to the naked eye, but most of the energy is outside the visible range. These flares may also release a flare spray, which involves the release of material that is faster than a solar prominence. Particles released from a flare spray may attain a velocity of 20 to 200 Kmps. To put this into perspective, the\u00a0speed of light\u00a0is 299.7 Kmps.<\/p>\n\n\n\n

How often do these flares occur?<\/h2>\n\n\n\n

Smaller flares occur more often than large\nsolar flares<\/strong>. The frequency of any solar or stellar flare<\/strong> depends\non the Sun\u2019s activity There may be several flares per day during an active part\n11-year solar cycle. There may be even 20 flares a day and over 100 per week\nduring peak activity.\n\nCurrently, scientists are not in the state to\npredict a solar flare<\/strong> with any rate of accuracy though they can guess it\nwith high sunspot activity which is associated with the chance of flare\nproduction<\/strong>. The process of observing these kinds of a sunspot is called\ndelta spots. These spots are used to calculate the probability of flare\noccurrence.\n\n\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"
