The cloud of plasma ejected by the Sun reached Earth in the morning of June 1, which may provoke magnetic storms of the maximum level.
The speed of the solar wind in some places exceeds 1000 km/s, and the plasma temperature is over 3.5 million °C, which is several dozen times higher than normal and even higher than the temperature in the solar corona, according to the Laboratory of Solar Astronomy of the Space Research Institute of the Russian Academy of Sciences.
The head of the Laboratory, Sergey Bogachev, noted that if such indicators are indeed associated with the plasma ejection that occurred on May 31, then it reached Earth in a record short time — less than 30 hours, which is almost a day earlier than predicted.
There is a possibility that it was just a fast and small fiber of plasma, and the main mass of the substance may arrive later and turn out to be less active. However, if the main ejection has reached Earth, then magnetic storms of the highest, fifth level are possible today.
