Sun erupts the biggest solar flare of the past four years

Large solar flare from sun drops radio signals on Earth

The sun, which is a source of energy, could sometimes be the center of the deadly radiation that is thrown at us. One of these eruptions exploded from a sunspot named AR2838 on July 3, said the Center for Space Weather Forecasting. Sunspot AR2838 broke through the sun’s surface and triggered the strongest solar flare in four years, an X1.5-class explosion. The now-vanished sunspot occurred over the northwestern end of the star and is likely to move to the other side of the sun in the coming weeks.

According to spaceweather.com, if the sunspot holds together, it will return to view from Earth in late July. The most recent eruption marks the beginning of a new solar cycle. The X-class solar flare ionized the upper part of the earth’s atmosphere and caused a shortwave radio dropout over the Atlantic.

Known for damaging electrical transmissions and equipment, the July 3 flare did not disappoint as it created a radio burst, ionospheric disturbance, a ground surge, and a deflection of local magnetic fields. The flare caused the ionization of the upper part of the earth’s atmosphere and caused currents to flow 60 to 100 km above the planet’s surface, thereby changing the polar magnetic field.

A solar flare is a sudden, rapid and intense explosion on the sun’s surface that occurs when huge amounts of energy stored in magnetic fields are suddenly released. The explosion sends out radiation throughout the universe and sends it towards the planets of the solar system. These radiations include radio waves, X-rays, and gamma rays.

According to NASA, the energy released in this explosion could be equivalent to the simultaneous explosion of millions of 100 megatons of hydrogen bombs; however, it is only a tenth of the total energy that is emitted by the sun every second. Solar flare: First, the preliminary stage, in which the release of magnetic energy is triggered by weak X-rays. The second stage, known as impulsive, is when the protons and electrons are accelerated to energies equivalent to one million electron volts. The third stage represents the gradual accumulation and decay of X-rays.

Scientists classify solar flares based on their X-ray brightness and are divided into three types: the solar flare that erupted on July 3rd was an X-class eruption, which is the largest; These types of flares have the ability to trigger radio outages. The medium class eruptions are known as M-class and affect the Earth’s polar regions, while the smallest are those of Class C with minimal impact on Earth.
