Solar flare: is a sudden flash of brightness observed near the suns surface. It involves a very broad spectrum of emissions an energy release of typically 1 x 10 power 20 joules of energy for a well-observed eventsolar flare affect all layers of solar atmosphere (photosphere-chromoshere and corona).when plasma medium is heated to tens of millions kelvins while the cosmic-ray-like electrons-protons and heavier ions are accelerated to near the speed of light. they produce radiations across the electromagnetic spectrum at all wavelengths from radio waves to gamma rays.
X-ray and UV radiations emitted by solar flares can affect Earths ionosphere and disrupt long-range radio communications. Direct radio emmision at decimetric wavelengths may disrupt the operation of radars and other devices that use those frequencies.
