In one of the active regions of the Sun, a powerful flare occurred, part of the radiation from which can reach the Earth.
The Watchers writes about it.
A powerful M8.2-class solar flare reportedly flared up at 14:19 UTC on September 20, 2023. The event ended at 14:25 UTC (17:25 Kyiv time).
According to the publication, type II radio emission with an estimated speed of 1054 km/s was recorded.
A collision with the Earth's magnetic field, which protects our planet from too dangerous shock emissions from the Sun, will lead to the appearance of a not very strong geomagnetic storm.
Such a storm can cause a short-term blackout of communication on the planet, and can also lead to the failure of power systems. Another consequence of the fact that solar plasma will crash into the Earth's magnetosphere will be the appearance of bright auroras much to the south of their usual appearance.
According to scientists, the approach of the Earth and the Sun and the appearance of a flare on a star with the ejection of plasma is an absolute coincidence and is not a natural event.
Coronal mass ejections, which lead to the appearance of geomagnetic storms on Earth, occur in special regions on the Sun called sunspots. When the magnetic field lines on the surface of the Sun become too entangled and suddenly break, a flare occurs, but it is not always accompanied, as in this case, by plasma ejections. If the sunspot is directed towards our planet, then a stream of plasma flying through space at great speed crashes into our magnetic field.
In recent months, there have been a lot of flares with coronal mass ejections on the Sun, and this is happening for a reason. The fact is that the Sun has an 11-year cycle of its activity with periods of calm and maximum ascent. The latter is called the solar maximum, and our star is gradually approaching it.
According to the forecasts of scientists, the peak of solar activity will come in July 2025, and before that, eruptions will increasingly occur on our star, which will cause geomagnetic storms of varying strength.
