Wednesday, September 6, the Sun has been powerful over the last 12 years of flash, resulting from the merger of the two largest groups of sunspots, according to Laboratory x-ray astronomy of the Sun Physical Institute named Lebedev.
«Events of such power are the most major that are only able to produce our star and which are formed only under very rare conditions, usually at the stage of peak solar activity. As it so happened that an outbreak of this level has occurred now, in the context of the solar minimum, yet to understand scientists,» RIA Novosti quoted the Russian astronomers.
Flashes on the Sun depending on capacity of x-ray radiation share on five classes: A, B, C, M and X. Minimum class A0.0 corresponds power radiation at the Earth’s orbit in 10 NW per square meter. When moving to the next letter power increases 10 times.
Today’s flash belongs to the latter class X, and she was rated a score of X9.3, making it one of the five most powerful explosions on the Sun’s surface that occurred during the observations of similar events. According to scientists, it occurred at the point facing the Ground, and therefore its impact on our planet will be at its maximum. While the consequences for life on Earth, astronauts and satellites in orbit can not be predicted, we will know in a few days.
According to experts of the laboratory, the current level of solar activity went beyond a ten-point scale, reaching 10.3, and is now in the so-called «black» area.
Flash, generally accompanied by emission of solar plasma clouds which, in the case of reaching the Earth, can trigger magnetic storms.
