Scientists believe that a strong geomagnetic storm will occur on Earth in the coming days.
The Sun is again restless . A new spot called AR3058 appeared on our star, which caused a fairly powerful class M solar flare and coronal mass ejections. As a result, a huge amount of solar particles went to the Earth, which, after colliding with the magnetosphere, will cause a G2 or even G3 class geomagnetic storm. The beginning of the storm should be expected as early as July 19, according to Interesting Engineering.
Scientists believe that as a result of a new solar flare, the Earth will be directly hit by streams of solar particles, since the new sunspot AR3058 was directed towards our planet. According to NASA's forecast, solar particles will reach the Earth on July 19 and a medium power geomagnetic storm will arise, which may continue on July 20 and 21.
According to scientists, an M-class flare with a serial number of 2.9 appeared on the Sun. We remind you that all flares on the Sun come in five classes and they are named A, B, C, M, and X. Class X flares are the most powerful and most dangerous phenomena for the Earth. But class M flares are not far behind class X flares in terms of yield. As for serial numbers, in each class of flares their level is measured on a scale from 1 to 9.
This new outbreak will cause a G2 or even G3 class geomagnetic storm, according to scientists who monitor space weather. Geomagnetic storms also have 5 classes, and the second and third classes of storms correspond to the average level of storm power.
But even the average class of a geomagnetic storm can cause severe disruptions to the operation of GPS and radio communication systems on Earth. Also, these storms can lead to interruptions in the operation of electronics and ground power systems. Scientists also expect the appearance of stronger auroras and not only in the polar latitudes.
Scientist Tamita Skov of the non-profit American organization Aerospace Corporation shared on Twitter a model of a “sunstroke” on the Earth, which was created by NASA.
The sun is now in a near-peak phase of its activity, which will come in a few years. But explosions and ejections of powerful plasma streams have been constantly occurring on our star since the beginning of the year. They are not always directed towards the Earth, but when they do, it sometimes causes problems.
Scientists can often predict the occurrence of geomagnetic storms, but this is not always the case. For example, in early July, our planet was hit by a G1 class geomagnetic storm, which was very weak, but it caused very bright auroras. But the most important thing is that scientists did not notice this storm and it became known only after the fact.
Scientists believe that even more solar flares should be expected in the near future, and most of them may be class M, although some and solar explosions will belong to class X.
The Sun has an 11-year cycle of activity, during which our star alternately “calms down”, then more and more “shows character”. A new solar cycle began in 2019 and in 2024 or 2025 there will be a period of the greatest activity of the Sun, when there will be more sunspots and very frequent eruptions on our Star.
Focus I already wrote that at the end of June, a phenomenon called a solar tornado occurred on the Sun. Then a whirlwind from the plasma escaped into space at a distance of 20 thousand km.
