Informative Speech: Solar Flares

Purpose statement: Please introduce solar flares to our audience. Introduction I. Solar flares are intense gas eruptions that emit ultraviolet light, x-rays and gamma rays. This is an explosion of huge hydrogen and helium on the surface of the sun. A. This is a sharp and sudden brightness change every 11 years. They usually last an average of 20 minutes and are a very obvious phenomenon. C. Imagine a huge piece of material bound by a strong magnetic force. They suddenly entered the Earth's magnetosphere.

Sometimes, a sudden and sudden change in brightness can be seen under the sun. That is the solar flare. Solar flare occurs when the magnetic energy accumulated in the solar atmosphere is suddenly released. There is a huge magnetic ring on the surface of the sun called protrusion. When they come in contact, they short-circuit each other causing an explosion. The energy released is the same as the explosion of millions of megatons of hydrogen bomb at the same time. The solar flare contains high energy photons and particles and is emitted from the sun in a relatively short time (several minutes).

Solar flares are a phenomenon in which the sun suddenly releases a large amount of solar radiation far beyond normal conditions. Although solar flare is rarely directly damaged, it may damage electrical equipment. In the Carrington case in 1859, the sun's storm caused a disaster to destroy the telegraph network, and the March 1989 geomagnetic storm may have caused Quebec in trouble. Among the famous solar flares are X20 events on August 16th 1989 and similar flares on 2nd April 2001. The most powerful flare (between X 40 and X 45) occurred on November 4, 2003
