The fourth consecutive powerful explosion occurred on the Sun-May 15, 2013,
which can lead to problems with radio communications on Earth,
according to RIA Novosti, the representative of the Institute of Applied
Geophysics Hydromet (IPG).
0600 medium (02:00 UTC) all in the same active region, as yesterday,
there was an outbreak of class X, is the fourth in two days. Unusually
vigorous activity of this group continues, but it geoeffectiveness is
still small, and the main effect is to deterioration of the conditions
of radio propagation on the illuminated side of the Earth during the
outbreak, "- said the source.
Solar flash depending on the power of X-ray radiation are divided into five classes: A, B, C, M and X. Minimum class A0.0 corresponds to the radiation power in the orbit of the Earth in 10 nanowatts per square meter. When you move to the next letter of the power is increased tenfold. Outbreaks are often accompanied by emission of solar plasma. If the plasma cloud reaches Earth's magnetic storm begins.
outbreaks have become the most powerful burst of solar activity from
October 23, 2012, when the Sun X-ray flare occurred class X1.8.
The sudden burst of solar activity does not give reason to speak of a
"turning point" in the behavior of the stars, told RIA Novosti the
laboratory X-ray astronomy of the Sun Lebedev Physical Institute (LPI)
However, according to Bogachyova until a group of sunspots, which are
associated with the outbreak, is still beyond the edge of the sun, and
now "it is not clear what it looks like, so this prediction (new
outbreaks) can not be given."

He said it was too early to talk about the global change of the trend in solar activity, which has recently been fairly calm.
As previously reported, the solar activity in 2011 instead of the
expected output to the maximum stopped growing and last year was four
times lower than the maximum values recorded during the 260 years of
The scientist said that the largest outbreak in the history of
observations of the Sun at the end of 2003 occurred on the decay of the
previous solar cycle.
At the same time, NASA experts earlier speculated that perhaps instead
of a single peak in 2012, the maximum will actually be a "two-headed",
with peaks in 2011 and 2013.
Solar shots this time were not directed at Earth, but how much energy at all, still do not understand even the scientists. Read more >>
