Scientists from the international group of physicists from Russia, UK and the U.S. working at the University of Lancashire recorded a powerful flash of ultraviolet radiation in the solar corona. Outbreaks are somewhat similar to the sparks have a diameter of approximately 680 kilometers, or comparable to the entire territory of the United Kingdom.
Observed flashes was for 25 seconds, and during this period they released up to 1024 joules of energy. This phenomenon - the evidence is very localized and frequent outbursts of energy, which can then accumulate and easy to heat the solar corona. Outbreaks have found posts due to a solar telescope suborbital Hi-C, despite the fact that the device is able to operate up to failure of a couple of minutes, the collected data were telescope unique enough to make several important discoveries.
It should be noted that the solar corona - the most intense emission region luminaries. The temperature in the corona reaches a million degrees, while the surface of the sun warmed up only up to 6000 degrees. The cause of warming up of the crown may be magnetic perturbations, however, scientists still are not entirely clear mechanism of this process.
