What is Sun Storms

Oct 6, 2009


Although the Sun is a calm star than other stars in the universe, it still has several forms of violent storms that occur often in sun's atmosphere. These include prominences, solar flares, solar wind, and sunspots.

Prominences: These storms are clearly seen from Earth. It looks like bright arches or loops of gas. They originate in cromosphere and sometimes bend backwards and shower gasses back to Sun. Some prominences ignite to heights of up to one meg kilometers and distance former the sun's layer.

Solar flares are observed as bright bursts of light on the Sun’s surface. These storms usually last less than an hour and can reach temperatures that are two times the rest of the Sun’s surface. Huge amounts of energy are released during a solar flare that sometimes interferes with telecommunications on the side of the Earth facing the Sun. These storms are sometimes accompanied by the Northern and Southern Lights.

Solar wind is a continuous stream of high-energy particles that is bursted into space in all directions from the Sun’s corona. The wind may be increased in speed by solar flares. Solar wind will cause interference with radio signals and telephone networks on Earth. It also affects the way the end of a comet is nibbed, which is ever gone from the Sun.

Sunspots are observed as dark areas on the Sun’s surface and also they are relatively colder than other areas of the Sun. They are observed in the photosphere and range from sixteen to 160,000 km in diameter. The number of sunspots is always keeps on changing, but it is observed that there is huge change in their number every ten to eleven years. Because sunspots are shown to move on the Sun’s surface, it was inferred that the Sun is rotating on an axis. Since it is filled up with gas, the sun rotates faster at the equator at around 26.8 days per rotation, than it does at the poles, which lasts for about 35 days.
