Solar flares in the sun September. The sun again happened a powerful flash. Flash in the sun consequences

17.04.2021

From 4 to 10 September 2017 The sun occurred a series of sufficiently powerful solar flareswhich media immediately began to frighten the inhabitants. What is a solar flash? What was special in the solar flashes of September 2017? What threatens the outbreak in the sun to people on earth? Let's try to figure out. So, about complex matters of simple words.

Our star Sun is a gas ball in which hydrogen as a result of the reaction of thermonuclear synthesis turns into helium, highlighting a huge amount of energy. The temperature in the center of this ball reaches 14 million degrees (on Kelvin, as well as Celsius), and only 6 thousand on the surface.
All this mixture is heterogeneous, and convective streams are cut from the depths of the surface thermal energy. Sometimes the complex magnetic field of the Sun begins to suppress the convective movement in some places. There seems not enough to fit the area, which from the ground looks darker of the surrounding regions.
This phenomenon is called - solar spots. Especially active solar spots are generated during the solar activity, which comes from our star about once every 11 terrestrial years. In the period of the solar minimum stains in the sun appear less often.

Solar flash is an explosion in the sun atmosphere. It usually occurs in places of interaction between itself solar spots with opposite magnetic polarity.

The energy highlighted by one such explosion is comparable to the amount of energy that humanity on Earth would have consumed a million years. Flash photons fly to our planet for 8.5 minutes, then the powerful flows of charged particles and clouds thrown out of the sun plasma are suitable - after two-three days. From the catastrophic consequences, our land saves her magnetic field. Everything that threatens us is magnetic storms, interference in radio communications, mobile phones and navigator work, etc., some deterioration in meteo-dependent people. But in the polar regions, and sometimes in medium latitudes, you can observe a beautiful phenomenon - the Northern Lights.

Depending on the intensity of X-ray radiation, the flash is assigned a specific score consisting of Latin letters and numbers. The most powerful is marked by the Litera X. It is possible to reliably measure the power of the flashes. It became possible only with the beginning of the cosmic era, because the X-ray radiation does not reach the surface of the Earth.

Since the start of measurements, the most powerful outbreak was registered on November 4, 2003 and had a score X28. Most likely there were no less, and more powerful solar flares. The outbreak of September 1, 1859 was not measured, but it caused the refusal of all telegraph systems and the northern lights even on the caribbean. On May 23, 1967, the American missile warning systems in the polar regions were disabled as a result of the solar outbreak, which almost led to the beginning of the atomic war.

Sunny flashes of September 2017 were not very powerful and did not have a significant impact on Earth. The most powerful of them had a score x9.3, which makes it only the 14th in statistics for the measurement period. The peculiarity of September sunny events is only that they occurred in the year of the "relaxing sun". The current solar cycle began in December 2008, and now we are moving towards the solar minimum when the outbreaks should have been rare and not intense.

Three strong outbreaks in the sun recorded astronomers over the last week. The first one is named the most powerful over the past twelve years.

What is dangerous this astronomical phenomenon and what consequences can lead - read in the selection of the most important facts from the site "24".

What is solar flash?

This is a heavy duty process of highlighting light, thermal and kinetic energy in all layers of the solar atmosphere. It lasts a few minutes, while releaseing billions of megaton energy in TNT equivalent.

What kinds are there?

The Sun explosions are classified in five types: a, b, c, m, x. Flare type A is characterized by the minimum degree of X-ray radiation - 10 rope per square meter, and each further species intensively than the previous 10 times. The most powerful and most dangerous are the outbreaks of the class X. It is over the past few days, and one of them is assigned a score x9.3.

Why arises?

The flash in the sun usually occurs near the neutral line of the magnetic field, which separates the sections of the North and South polarity. Its frequency and power depends on the phase of the solar cycle. Recent outbreaks noticed in a geo-efficient area near the line Sun - the Earth, where the sun's effect on our planet is maximum.

What is dangerous?

Each flash in the sun forms a plasma cloud, which, reaching the earth, can cause magnetic storms. Now on our planet, according to scientists of the Physical Institute of the Academy of Sciences, its capacity occurs 10 times more than it was supposed. Also, scientists associate the emergence of natural cataclysms, such as typhoon, hurricanes and earthquakes with outbreaks in the sun.

In confirmation of this fact - a powerful, which swept along Texas at the end of August, causing a strong flood in Houston, and, which was already due to the life of 14 people, continuing to rage in the Caribbean. The colossal damage caused and, which can grow into tsunamis.

Magnetic storm forecast in September 2017 from tochka.net It is useful to all meteo-dependent people.

The beginning of autumn promises several serious outbreaks of solar activity. In particular, on September 6, there was a powerful explosion in the sun, which scientists have assigned a H9.3 score on a 10-point activity scale. Over the past 12 years, this is the largest flash in the sun. Today, the consequences have not yet been studied by specialists. However, the level of flare activity went beyond the scale of the scale and is 10.3 points.

In this regard, it is expected to be a serious effect of outbreaks in the sun per person. It is possible to deteriorate well-being, as well as failures in the operation of communication systems, the Internet, and even the refusal of space technology.

Also expected tangible magnetic storms in mid-September and at the end of the month. Therefore, you should be alert so that they do not find surprise, did not spoil the well-being and mood at the beginning of the school year.

of the year

During September 2017, the strongest manifestation of solar activity is expected.

Magnetic oscillations are possible 2, 6, 17, 26, 30 numbers.

Magnetic storms are expected 1, 7, 8, 9, 13, 14, 15, 16, 24, 27, 28, 29 numbers.

Previous flashes

A series of outbreaks on the luminaire began back on Monday - then the scientists recorded five emissions of the energy of class M. Already two days later, scientists declared the outbreak of the outbreak in the last 12 years. The flare is assigned a score x9.3.

On September seventh, the second most powerful outbreak occurred, which was assigned the highest class of activity - H. As scientists said, which occurred was the natural end of the changes in the solar crown.

The eighth of September there was a third powerful flash, which was also attributed to the class X.

"Sunflowing"

As scientists stated, during the first powerful outbreak in the Sun, seismic waves were distributed, called the "Sunflowing".

However, experts noted that this phenomenon is no harm.

"Almost no one will notice anything," said Alexei Struminsky, the leading employee of the Institute of Space Research.

"Placebo effect"

In the Moscow Space Club, they said that the effect of outbreaks in the sun, even powerful, on the state of health of earthlings with science has not yet been proven, but the so-called "placebo effect" from reading reports of increased solar activity can lead to a deterioration of psycho-emotional state.

"For such facts, scientific research has not yet been recorded. Theoretically - yes, it is possible, but practically it is not proven. It should be understood that the" placebo effect "in the sensations of people reading news about outbreaks, as well as stains in the sun, effectively affects them Physical and psycho-emotional state. A person is worried, expects trouble, here they are taking place, "said Ivan Moiseev.

The placebo effect, as scientists believe, leads to a deterioration or improvement of human health due to the fact that it believes in the effectiveness of some exposure from the outside, in reality neutral.

In the first half of the Wednesday, September 6, 2017, scientists registered the most powerful solar outflow over the past 12 years. The outbreak was assigned a score x9.3 - the letter means belonging to the class of extremely large flashes, and the number is the power of the flash. The release of billions of tons of matter occurred almost in the AR 2673 area, almost in the center of the Solar Disc, so earthlings did not avoid the consequences of what happened. The second powerful flash (X1.3 score) was recorded in the evening on Thursday, September 7, the third - today, on Friday, September 8.

Sun throws out huge energy into space

Solar flares Depending on the power of x-ray radiation are divided into five classes: a, b, c, m and x. The minimum class A0.0 corresponds to the radiation power in the orbit of the Earth at ten rolled into the square meter, the next letter means an increase in power tenfold. In the course of the most powerful outbreaks that the sun is capable of surrounding the surrounding space, a huge energy is derived in a few minutes - about a hundred billion megatons in Troatil equivalent. This is an approximately fifth of the energy emitted by the Sun in one second, and all the energy that humanity will produce for a million years (subject to its production with modern pace).

Powerful geomagnetic storm is expected

X-ray radiation comes to the planet in eight minutes, heavy particles - a few hours, plasma clouds for two-three days. Coronal release from the first flash has already reached the Earth, the planet has encountered a cloud of solar plasma with a diameter of about one hundred million kilometers, although it was previously predicted that this would happen in the evening of Friday, September 8. The geomagnetic storm of the G3-G4 level (the five-point scale varies from weak G1 to an extremely strong G5), provoked by the first flash, must end in the evening on Friday. Coronal emissions from the second and third solar flares have not yet reached the Earth, the possible consequences should be expected at the end of the current - the beginning of the next week.

Flash consequences have long been clear

Geophysics predict polar radiance in Moscow, St. Petersburg and Yekaterinburg, cities located on relatively low latitudes for avrore. In the US state, Arkansas have already noticed him. Back on Thursday, operators in the United States and Europe reported non-critical communication interruptions. The level of X-ray radiation at the near-earth orbit increased slightly, the military clarify that satellites and ground systems, as well as the crew of the ISS direct threat.

Nevertheless, there is a danger to low-bit and geostationary satellites. The first risks are out of order due to braking about the heated atmosphere, and the second, having removed from the ground by 36 thousand kilometers, may face the solar plasma cloud. Possible interruptions with radio communications, but for the final assessment of the effects of the outbreak, it is necessary to wait at a minimum of the end of the week. The deterioration of the well-being of people due to changes in the geomagnetic situation is not scientifically proven.

It is possible to strengthen solar activity.

The last time a similar flash was observed on September 7, 2005, but the strongest (with a ball x28) occurred even earlier (November 4, 2003). In particular, on October 28, 2003, one of the high-voltage transformers in the Swedish city of Malmo came out of the system, leaving the entire settlement for an hour. From the storm suffered other countries. A few days before the events of September 2005, a less powerful outbreak was recorded, and scientists believed that the sun calms down. What happens in the last days is strongly reminded of the situation. Similar behavior of the lamination means that the 2005 record in the near future can still be beaten.

However, over the past three centuries, humanity survived and even more powerful solar flares than those that occurred in 2003 and 2005. In early September 1859, the geomagnetic storm led to the failure of the telegraphic systems of Europe and North America. The reason called the powerful emission of the coronal mass, which has reached the planet for 18 hours and observed on September 1 by the British astronomer Richard Karrington. There are also studies questioning the consequences of the solar outbreak of 1859, scientists that the magnetic storm affected only the local areas of the planet.

Solar flares are difficult to quantify the description

The sequential theory describing the formation of solar flares is not yet. Flashing arise, as a rule, in places of interaction of solar spots on the border of the areas of northern and southern magnetic polarities. This leads to a rapid release of the energy of magnetic and electric fields, which then goes to heating the plasma (increasing the speed of its ions).

The observed stains are sections of the sun surface with a temperature of about two thousand degrees Celsius below the temperature of its surrounding photospheres (about 5.5 thousand degrees Celsius). On the darkest parts of the magnetic field stains perpendicular to the surface of the sun, on the brightest they are closer to the tangent. The magnetic field strength in such objects exceeds its terrestrial value in thousands of times, and the flashes themselves are associated with a sharp change in the local geometry of the magnetic field.

The solar flare occurred on the background of a minimum of solar activity. Probably, thus the luminary drops the energy and will soon calm down. Such a kind of events took place earlier in the history of the star and the planet. The fact that today is attracting the attention of the public, it is not about a sudden threat to humanity, but about scientific progress - in spite of everything, scientists are gradually increasingly understanding the processes taking place with the star and inform about this taxpayers.

Where to keep track of the situation

Information about solar activity can be learned from a variety of sources. In Russia, for example, - from the sites of two institutions: and (first at the time of writing the article posted a direct warning about the danger for satellites due to the sun outbreak, the second contains a convenient graph of flash activity) that use the data of American and European services. Interactive data on solar activity, as well as assessing the current and future geomagnetic situation can be found on the website
