The outbreak occurred on April 25.
A restless sunspot caused a double flare in the Sun, which took place on April 25. It has led to a short-term disconnection of radio communications over Asia and Australia, according to Science alert.
Sunspot AR2993 exploded with two flashes of class M1, ie medium power. Such flashes can cause short-term radio problems and expose astronauts to higher-than-usual radiation exposure. According to astrophysicist Dean Pesnell, the AR2993 spot was medium in size, but at the same time it reached hundreds of millions of square kilometers. “The Earth could lie in it as comfortably as an egg in a nest.”
Sunspots are regions in which the Sun's magnetic fields are much stronger than in the surrounding regions. These magnetic forces block the flow of hot gas from the Sun's interior, making sunspots much colder than the surrounding areas. Solar flares occur when magnetic field lines near sunspots are dramatically reorganized.
Sometimes these radiation emissions also cause coronal mass emissions, which are solar plasma explosions. In recent weeks, several sunspots have appeared on the Sun, some of which were stronger than the April 25 flashes.
Yes, on April 19 and 20, another spot, AR2992, released a powerful X-Class flash. Such flares are 10 times more powerful than Class M flares. However, the spot was directed towards the Earth, and therefore, our planet was not affected by a powerful flare.
Recall, in late March, scientists recorded in the Sun class M1.1 outbreak. Despite the average force, the flash lasted almost four hours, as a result of which a large amount of material was released into space.
