The month of June began with new strong explosions on the Sun. The phenomena were recorded by the “eyes” of NASA’s Solar Dynamics observatory
The stain that caused the extreme geomagnetic storm in May it remains active. Now called AR 3697, the region continues to hurl clouds of electrically charged particles into space in intense eruptions, which were recorded by the Solar Dynamics observatory at NASA.

This active region has been named AR 3664 and has caused some of the strongest solar flares of the current cycle on our star. As the Sun rotated, the churning formation moved away from Earth during mid-May. Now she’s back.
On May 27, the slick released an eruption classified as X 2.8. Solar flares are classified according to intensity: the weakest are class B, while the strongest are class X.
On the 29th, the spot triggered an X 1.45 explosion, followed by another classified as X 1.1 on the 31st. On June 1, AR 3697 released not just one, but two explosions classified respectively as .

It appears that the explosions occurred alone, without being accompanied by coronal mass ejections. Coronal mass ejections are large masses of solar plasma and magnetic fields that, when they reach Earth, cause the aurora borealis and other effects.
However, this does not mean that AR 3697 has become calmer. On Sunday (2) two class X and 10 class C explosions occurred in the active region, which are not expected to cause any noticeable effects on our planet.
These phenomena remind us that the Sun is reaching solar maximum, the name given to the period of greatest activity in its 11-year cycle. Therefore, although AR 3697 has already shown significant activity, there may be some other region Sunspots rise in our star – and, who knows, maybe it will give us something beautiful northern Lights.
What is a solar flare?
As the name suggests, solar flares are powerful releases of energy from the Sun. Exposures, along with solar flares, can affect communication radio waveselectrical networks and navigation signals.
They are also dangerous for astronauts, especially if they perform an activity outside the protection of their spacecraft.
