Experts expect the powerful solar flares, which can cause a planetary catastrophe
About the beginning of the end of the world in 2012, NASA has warned humanity in 2009. Then in April, experts of the agency and the American Academy of Sciences (NAS), studying solar activity, issued a chilling report of his despair: "Threats to space weather: the social and economic consequences." "Komsomolskaya Pravda" sensation when first published (see "KP" on the site here). In the report, scientists afraid of coming global disaster that they expect from the sun.
According to them, the outbreak of unprecedented strength in the luminary may result in consequences comparable to a nuclear war or a collision with an asteroid. And this should happen, according to forecasts, on Saturday September 22.
What's going to happen? Please pass out the light. And the planet is plunged into darkness.
— Sudden changes in the electromagnetic field of the Earth caused by solar flares, suggest a strong DC — explained one of the authors of the report Professor Daniel Baker, a space weather expert at the University of Colorado and chairman of the committee of the American Academy of Sciences (NAS). — It was he able to literally burn the electric network is not designed for such loads.
The most vulnerable elements — transformers. They quickly overheat and melt. Experts estimate that in the U.S. only 90 seconds after the impact will burn 300 key transformers. And without electricity will remain more than 130 million people. Next, start the so-called rolling blackouts. After all, energy networks in the continents are interconnected. Stop trains, elevators, industrial production, falling satellites, aircraft, stops water and heat. Flow refrigerators. Silent radio, no TV show, cut off communication … The end. There's no light. And will not.
The sun still calm. But it may well rage.
Fearing the development of such a horrific scenario, the Americans even started in 2010 in the space a unique device — Solar Dynamics Observatory (SDO). He will follow the luminary five years, continually removing and transferring it to 60 images per minute. Moreover, the picture quality is 10 times greater than that which now offers high-definition television. Each image is passed to it of 16 million pixels. A data each day forwarded to the Earth exceed "by weight" half a terabyte. Approximately the same amount of 500 thousand songs, if downloaded from the Internet.
According to Liz Citrin, one of the leaders of the project at NASA experts expect to get a complete picture of how distributed streams of plasma that is created on the surface of the sun, and which — in his match anomalies observed from the outside. In general, the unit charged with the task of helping people learn how to make solar weather forecasts, predicting the powerful storms and storms.
But to this day nothing frightening SDO does not "see." And so do not warn the people on Earth of an impending disaster.
But ahead — two more days. And as scientists assure, image and data transmission SDO, will react immediately. This will leave about 17 hours to turn off the electrical sub-stations and satellites translate into standby mode. As a result, the damage can be reduced. But without the light will have to sit still.
And science fiction writers SCARE THE SUN
In at least two thrillers, "The Sign" and "2012" is a source of light of global catastrophes. In the first film, plasma, self-inflicted raging beyond measure star, burning Earth. In the second — is powerful tectonic shifts, causing the destructive processes in the subsurface. In the first case, it comes to a complete end of the world without any possibility of escape. In a second — before partial.
Director of the Astronomical Observatory of Irkutsk State University, Doctor of Physical and Mathematical Sciences Sergei Yaz:
— Sergei Arkturovich, scares you report NASA?
— I am absolutely amazed by this unprofessional outlook NASA. Nobody in the world can not predict solar flares are not only three years, but even this month.
I myself have been doing flash for a long time. I watched them through the telescope itself for a long time. I have a good experience. And I can tell by looking through a telescope that will be the flash somewhere in an hour, and can be — and never will. And even with my experience I can not really say about it. But a month, two months, six months, and so on to predict — it's just nonsense.
Moreover, it is a very low level of solar activity. Even admit that I, as a specialist, now there just is not interesting to watch. On luminary now have a group of spots, but they are small. And it was yesterday, and today three hilenkie flash.

— Two days can not be formed for a huge number of spots that will give a powerful flash?
— There were such cases, when a group of sunspots developed rapidly for a day, for two to very large values. But no one ever knows how to predict these things.
— Then, it turns out, Americans have come up with?
— I speculated. No serious expert heliophysicist agree with this prediction could not be. All the predictions that there are confirmed. We see that the current cycle of solar activity — 24 minutes — very "low." Spots in an amount which is the case in other cycles, no, apparently not. Sunspot group average in size.
I can predict that the peak of the current cycle will be very low and featureless. And it will continue year and a half. But it is not directly comparable with the maximum of the 19th cycle in 1957. Then, just at times there were more spots were the most powerful flash. But all survived.
— On Earth, it has no effect then?
— All are alive.
— If, however, the cataclysm happens, no light will stay?
— In order for all this to happen, we need such powerful flares, which we hardly ever saw. Silnyae flash, of course, there were, they investigated, and I watched them. They are caused by strong magnetic storms. And there were even some failures. But if you take a list of these failures when power transformers out of malfunction, this is the history of mankind only a few cases, and they are local, not global. A famous case in which the province of Quebec in Canada, a power transformer burned out due to too strong currents induced by particles from the sun flown. The whole province was without power for several hours. 1989. Experienced. In the 24th current cycle, I think it is extremely unlikely situation. Sometimes it happens that at a cyclical issue separate groups of spots are powerful enough flash. But it is a constant situation, nothing out of the ordinary.
— Space technology can cut down the flash?
— When you heard that some satellites because of these causes of failure? Long ago learned to do the technique so that it does not respond to the outbreak.
