A hyperactive sunspot will lead to a geomagnetic storm on Earth

Soon the Earth's atmosphere will "meet" with another series of solar flares. It is estimated that they will achieve

the planet's atmosphere by December 8–9. The source of the flares will be the hyperactive spot AR3153.

After a relatively calmer periodsolar activity, earthlings will experience a stream of high-speed solar winds and small geomagnetic storms. Its intensity is classified as G1, which is the least intense level.

Solar flares occur whenStrong magnetic fields arise in regions of the Sun, which temporarily stop the convection process on the star. It is known that solar storms last from a few minutes to several hours, but the effects of geomagnetic storms can persist in the magnetosphere and atmosphere of the Earth from several days to weeks.

The cause of such outbreaks may besunspots are dark areas on a star's surface, their strong magnetic fields are constantly shifting. When they quickly dissipate their stored energy, it can lead to the formation of solar flares and coronal mass ejections (CMEs).
