On September 10, around 6:00 PM Moscow time, our planet will be hit by another geomagnetic storm, which will continue into September 11. Earth’s inhabitants will face two consecutive solar flares, as two clouds of plasma are hurtling toward the planet. This material was ejected from the Sun's corona.
The probability of a direct hit — over 90%
In recent days, several solar ejections were recorded, but all were directed away from Earth. Some of the plasma clouds were expelled from the far side of the Sun, and in such cases, they pose no threat to us.
"For the evening of Tuesday, September 10, Moscow time, storms of level 1-2 on a 5-point scale are forecast. There is a moderate probability (about 30%) of auroras in the European part of the country," the laboratory’s website reported.
But this is only the prelude. On Monday, September 9, the Sun ejected new large clouds of plasma, and this time they are headed directly toward Earth. Scientists estimate the likelihood of a frontal collision at over 90%.
Incoming images show a fully formed plasma cloud about 30 million kilometers in size. It is racing toward Earth at a speed of about 800 kilometers per second.
"At these speeds, it will take around 50 hours for the cloud to transit from the Sun to Earth, meaning the arrival of the solar masses is expected by midday on September 11 (Wednesday)," said Sergey Bogachev. "It’s possible that the two hits on Earth will merge into one storm lasting about 24 hours."
The upcoming geomagnetic storm has been classified as G2, meaning medium intensity on a five-point scale.
On the way to Earth, some of the solar material could be absorbed by Mercury and Venus, and Earth's magnetosphere may deflect the remaining plasma cloud.
However, large and massive clouds often partially penetrate the upper layers of the atmosphere, causing geomagnetic storms. On such days, brief voltage spikes may occur in power grids. In polar regions, radio communications and satellite navigation equipment may experience disruptions. The most vivid manifestation of geomagnetic storms is the aurora borealis, which, under favorable conditions, can even be seen at mid-latitudes.
It’s also worth mentioning that during periods of heightened geomagnetic activity, doctors recommend that people with cardiovascular diseases monitor their blood pressure, keep prescribed medications handy, and avoid unnecessary stress. It is advisable to reduce salt intake and drink plenty of water.
Avoiding unhealthy foods, alcohol, and cigarettes is recommended. Instead, fresh air walks, massages, and alternating showers are encouraged.
