A strong geomagnetic storm hit Earth earlier on May 29. Scientists estimate its level at G3, with a maximum possible of G5. The cause of the powerful storm was new coronal holes on the Sun.
The peak of the magnetic storm occurred between 03:00 and 06:00 Moscow time. Then the observation stabilized, according to the Solar Astronomy Laboratory. However, scientists do not rule out new bursts of magnetic field activity during the day.
New coronal holes on the Sun are to blame. They cause the solar wind, which increases geomagnetic activity. In the case of new holes, this is a very strong wind, with a speed of 600 to 800 km/s.
Another feature of the new coronal holes is that they actively interact with each other. They form a single, extensive area. Scientists cannot yet understand what is happening inside this structure. It is difficult for them to predict what will happen in the coming days.
Although it is difficult to accurately predict the likelihood of new magnetic storms, scientists believe that the geomagnetic situation will be unstable for the next 3-5 days. This means there is a chance that Earth will be "storming" in the coming days.
