The American space exploration agency NASA has warned that a solar flare known as a solar flare will hit the earth today on July 19.
What is solar agitation?
From time to time, fiery lava is emitted into the sky from the Sun. This is called coronal mass ejection.
The plume spews solar material into the sky. NASA says it will take 3 to 5 days for the particles to reach Earth.
As particles from the Sun approach the Earth, the electronic components of satellites are affected. This will slightly affect the availability of signals such as radio and GPS.
When viewed from Earth, sunspots are visible. They are called ‘sun spots’. When the magnetic field lines near these sunspots, or sunspots, cross each other and rearrange their positions, solar flares, which eject solar particles, occur, according to NASA.
These solar flare events are the largest explosive event in our solar system. Energetic particles and radiation released from solar flares can cause severe damage to life on Earth. But, let’s not worry. Earth’s magnetic field and troposphere block them and protect us.
How does it work?
These solar flares occur as a result of extreme magnetic field variations on the Sun. These do not occur at regular intervals. Coupled with plasma emissions from the Sun, they can occur spontaneously at any time.

As these events take place in the Sun, there are systems that can control it in the form of a magnetic field. One is like a rope and the other is like a cage. To put it simply, this control system consists of cages formed by rope-like structures, with subsequent cages within them.
Last year, on October 24, 2014, researchers closely observed the solar flare that formed within a few hours. This agitation is associated with a flare from the Sun’s corona (outer layer). That is, the coronal region is hotter than the surface of the Sun. The cause of this extreme heat is not yet clear. Because of this heat, the magnetic field here cannot be studied.

But they used data from the Sun’s surface to determine what was happening 1,690 km above the corona.
The researchers also created some virtual models on supercomputers using data from NASA’s Solar Dynamics Observatory spacecraft. From there, they found that the ropes were not strong enough to break the cages. They also found that when the strings are wrapped tightly around each other, the collective release of energy results in a solar flare, like a big bang.
