Astronomers have recorded strong solar flare

Registered on the Sun's first major outbreak of 2011, relating to X-ray class M according to the standard classification in solar physics. Only in the scale of solar flares varies five classes: A, B, C, M and X, each of which exceeds the following prior to power 10-100. Event, more accurately estimated as M1.3, occurred late at night, Moscow time, and observed for about 20 minutes, with a maximum at 04:03 MSK. Preceded the outbreak of high solar activity, which has lasted for more than a day. Only from the middle of the day on January 27 at the Sun reported immediately 5 flashes, which are, however, very weak, said the Laboratory of X-ray astronomy of the Sun.

All a burst of activity associated with a solar active region, the catalog number 1149 NOAA, an ongoing National Oceanic and Atmospheric Administration of the United States. Under the separate numbers in this catalog are registered individual sunspots and sunspot groups that are large enough that they can be detected from the ground. It is in the vicinity of these groups, basically, and a solar flare. The reason is that sunspots are formed in places of greatest tension the solar magnetic field, and it is drawn from the magnetic field energy for all explosive processes on the Sun.

Currently active region 1149 is located on the western edge of the Sun at a longitude of 90 degrees. This means that tonight she will hide from view of the Earth, and the development of the current surge will not receive. Even if in this region the sun is still some free energy released in bursts, it is invisible to our side.

Outbreak occurred is the 22 th flash level M, which took place from the beginning of the new solar cycle, which is considered to be launched in late 2009. In general, a number of events that occurred during this period, it is the 12th place. The largest outbreak of a new 24-second cycle was recorded February 12, 2010 and had a level of M8.3. Since then, in spite of the gradual increase in activity on the Sun there were no more major events, including no outbreaks associated with the maximum X-ray class, X. This slow growth in activity is very unusual for the sun, and the last time there was, perhaps, only at the turn of the 1700s and 1800s, that is, at the dawn of regular observations of the Sun. Already, there are serious doubts that the sun can sustain its inherent rhythm of the 11-year-old and will reach a maximum activity in the proposed 2012-2013. A much more likely scenario may be considered a failure cycle. Finally confirm it, probably, it will be possible at the end of 2011, when the gap with the standard cycle has become such that it make up for the remaining 6-12 months will be impossible.
