Scientists warned of a strong magnetic storm

On Friday, August 8, the most powerful magnetic storm in the last two months may fall on Earth. Alerts about this were released in the laboratory of solar astronomy of Iki and HSFZ.

According to the forecasts of scientists, the moment of arrival to the ground of mass emission after a large solar outbreak that occurred On August 5, it will cause significantly stronger geomagnetic consequences than expected. “Since the plasma cloud after the explosion was thrown out not directly to the ground, but to the side at an angle of about 45 degrees, it was previously assumed that the touch of the planet would either not occur at all, or peripheral sparse areas of emitted solar matter would come to the ground. After the last recalculation, however, the models showed that the planet will touch the high -speed core of the cloud, and the blow to the magnetic field could be much stronger, ”the experts explained.

They predicted the beginning of a deterioration in the geomagnetic situation on the night of Thursday to Friday. A The arrival of plasma to the ground is expected on August 8 at about 7 am Moscow time.

“At the time of the blow, the growth of the geomagnetic index of KP to the value of 6 is predicted, which is the biggest value, starting from June 13, when the last time was registered A storm of this level. According to the space weather scale, events of this scale are considered medium, but are able to affect energy systems located on high latitudes, lead to the differences between the orbital demolition of spacecraft from the predicted and influence the spread of radio waves. Polar radiance with storms of this level are usually visible to a width of 60 degrees, but sometimes go down to a latitude of 50 degrees, ”the warning says.

It is noted that in general, the situation in the sun is currently “extremely complex”, and therefore the forecasts are radically changing with each update:

“The forecast for the storm on August 8 is also very sensitive to the actual direction of the plasma cloud, since the blow is still tangent. It is enough that the trajectory of the discarded substance deviates from the calculated only 3-5 degrees so that the storm does not occur. However, this works in the other direction: if the ejection deviates towards the planet, a storm of a higher score can occur. The probability of this is 5 %. ”

Recall that during outbreaks in the Sun, doctors recommend, if possible, to exclude physical activity, abandon bad habits and walk in the fresh air more.
