What is the impact of the strongest solar flare in the past 12 years on human beings?

Recently, the strongest flare in the past 12 years caused a lot of netizens' attention. What is the cause of the solar flare? What is the impact of the flare on our lives? On the evening of September 6, the solar flare x9.3, the strongest eruption since 2005, triggered the solar proton event and the coronal mass ejection.

There are two solar flares in the solar eruption, and the radio communication of the earth's sunny side is seriously disturbed. In the next few days, there will be other effects, for example, the most important form of aurora borealis.

Solar flares occur in a region of the sun with a slightly lower surface temperature, which scientists call the sunspot. Like the earth, the sun also has a magnetic field. It's like a rubber band with one end connected to the north pole of the sun and the other end connected to the south pole of the sun. With the rotation of the sun, the magnetic rings of the sun's magnetic field will be entangled, and constantly entangled together, resulting in the stronger and stronger sun's magnetic field. When the magnetic ring of the solar magnetic field is entangled to a certain extent, the accumulated energy will be released in the form of solar flares.

According to the intensity, solar flares are divided into C, m and X levels, and each level is divided into 1-9 levels from small to large. Level x is the strongest.

The two flares on Wednesday occurred in the sunspot region No. 2673, with the first flare rating of x9.3, followed by x2.2. The last time such a strong x-level solar flare was observed was on December 5, 2006, when the flare level was x9.0. This solar flare is even worse.

What is the effect of solar flares on daily life?

The possible effects of the rapidly increasing electromagnetic radiation, high-energy particles and magnetized plasma clouds in the solar storm on the propagation near the earth orbit are as follows:

The strong disturbance of the ionosphere interferes and destroys the radio communication and navigation system. The high-energy particle radiation damages the electronic devices of the satellite and endangers the life of the astronauts. The strong particle radiation changes the gas composition in the troposphere and stratosphere and affects the living environment of human beings, as well as the atmospheric environment change caused by solar flares and then affects the climate process.

Strong solar activity will cause some phenomena on the earth, such as auroras in lower latitudes (see the Carrington event), and instruments on the ground will react, such as the strong deflection of the geomagnetic indicator, interference with communication, etc. Some responses of terrestrial organisms have also been submitted, but whether they are related to large flares remains to be studied.

Solar flare is a flash phenomenon on the surface of the sun. It will release huge energy, which is more than six times of the total energy released by the sun per second. It can easily blow off the earth's atmosphere Solar flares are often accompanied by a large number of coronal mass ejections. Electromagnetic radiation in all frequency bands suddenly increases. Electrons, protons and heavier ions will be accelerated to near the speed of light, constantly bombarding the earth's atmosphere, trying to destroy the basis of life on which we live So the sun is not always the good news of life, occasionally it will also be tyrannical and neurotic.

Strong solar flares may destroy modern civilization In 1859, the strongest solar flare ever recorded made the telegraph system on fire. Even when the switch was turned off, the subatomic flow constantly sent information to a long distance automatically. The whole earth, including the equator, saw auroras, known as the Carrington event If this event happens today, it will severely damage all kinds of modern systems, a large number of facilities and equipment will be paralyzed or damaged, causing at least trillions of dollars of losses, and it will take four to 10 years to recover. Solar flares will also pose a huge threat to satellites in orbit and space station astronauts. However, due to the protection of the earth's magnetic field, life on earth will not be seriously threatened by solar flares, but will affect basic services such as water supply, medical treatment, transportation, communication, etc.

In the clear blue sky, the sun seems to be the same year after year, day after day, but astronomers have long known that this is not true. Does the sun change? A properly filtered telescope has found a hot disk often dotted with dark sunspots. Sunspots are subject to strong magnetic fields, which are also solar flares that illuminate the earth through X-rays and extreme ultraviolet radiation, and are also a kind of solar 'boiling' activity.

Solar activity can affect the space weather near the earth's magnetic field, which may include the temporary disturbance of the earth's magnetosphere called geomagnetic storm, Aurora, and the interruption of communication and navigation systems. The impact of the earth's upper atmosphere on low earth orbit satellites has also changed, and the threat to astronauts in space will increase. Power equipment and guide equipment will all Be affected.
