As a result of a solar flare, a G2 class geomagnetic storm was recorded on Earth.
Back on Sunday, August 7, scientists warned that a huge spot appeared on the Sun, which could provoke a powerful flare and coronal mass ejections. These are streams of charged particles that, upon reaching our planet, cause geomagnetic storms and negatively affect the operation of satellites, navigation systems and communication systems. The eruption on the Sun did occur late in the evening of August 7, but as of Tuesday August 9, streams of solar particles are still arriving at the planet at great speed, writes ScienceAlert.
The sun is a very unpredictable star, and yet scientists are trying to predict its behavior with the help of spacecraft. According to the forecast of NASA scientists, from August 7 to 9, another flare should have appeared on the Sun, which would have caused a strong geomagnetic storm, as Focus already wrote.
The sun struck the Earth with a strong blow
This eruption on the Sun nevertheless occurred late in the evening of August 7, and streams of charged solar particles went into space, towards the Earth. Already on August 8, these streams crashed into the Earth's magnetosphere at a speed of about 600 km/s, which led to the appearance of bright auroras in Canada and the USA.
As of August 9, these solar particle streams are still arriving at Earth, but at a speed of 550 km/s.
The geomagnetic storm will continue for several more days
According to scientists, starting from August 8, a G2 class geomagnetic storm began on Earth, which is considered moderate and will not have a strong impact on the operation of satellites and communication systems on the planet. In total, geomagnetic storms, depending on their destructive power, have 5 classes.
Experts have not yet classified the solar flare that caused the geomagnetic storm, but it is known for sure that it was, in contrast to forecasts, rather weak. Like geomagnetic storms, solar flares also have 5 classes. The last two in the classification, which are called M-flares and X-flares, are considered the most dangerous for the Earth. Solar flares and coronal mass ejections, eruptions of huge plasma streams, occur in sunspots. These are special regions on our star with their own distinctive characteristics.
Scientists believe that the geomagnetic storm will continue until the end of the week, although from the Sun in this time, new outbreaks can also be expected, which can be much stronger. Or vice versa, they will be quite weak. Estimates on this issue still differ.
According to scientists, almost constant geomagnetic storms of various strengths will become our life companions over the next two years. The sun is gradually increasing its activity as the solar maximum approaches – this is the period in the 11-year solar cycle when there are a lot of strong eruptions on the Sun. And this moment will come at the end of 2024, according to NASA forecasts.
But already this year, just giant sunspots were recorded on the Sun, some of which could easily swallow the Earth. Focus already wrote about one of these huge spots, which appeared in June of this year. Also, scientists have already recorded the appearance of the most powerful X-class flares possible on the Sun, which cause the strongest geomagnetic storms.
Focus already wrote that the distance between our planet and the Sun changes and scientists explained how it will affect all living beings on Earth.
Focus also wrote about a strong solar flare that occurred in July this year and caused the appearance of a geomagnetic G3 class storms.
