After several consecutive strong flares on the Sun, a magnetic storm began on Earth. According to experts, it has become the strongest in almost 20 years. According to the US National Oceanic and Atmospheric Administration, the storm reached its maximum level – G5 on Saturday night Moscow time. The previous time an extremely strong G5 storm was observed on Earth was on September 11, 2005.
Phobos center specialist Mikhail Leus noted that the events that occurred on the surface of the Sun could not but have a negative impact on the Earth’s magnetosphere. According to the expert, last evening the speed of the solar wind in just half an hour increased from 400 km/s to 700 km/s, and the density of the plasma surrounding the planet increased 30 times. By half past eight on Friday evening, the power of the storm had reached G3, within an hour it intensified to G4, the maximum level of G5 was reached by midnight.
By early morning in Moscow, the power of the storm had decreased slightly – again to G4. At the same time, the Solar Astronomy Laboratory of the IKI and ISTP SB RAS predicted that the storm would gradually weaken, but did not exclude periodic returns to stronger manifestations.
According to experts, by the afternoon Moscow time the storm had indeed again intensified to G5. The head of the Solar Astronomy Laboratory, Sergei Bogachev, told RIA Novosti that “the fastest masses ejected by the Sun” had arrived on the planet. According to him, the speed of the solar wind is now in the range from 800 to 1000 km/s.
“The climax begins. The magnetic storm is passing through the peak,” Bogachev noted.
Scientists believe that that the auroras will become more intense over the territory of the Russian Federation and will be visible even at unusual latitudes.
“It is possible that the oval will lower to the southern borders of the country,” Bogachev added.
