The aurora borealis appeared for the first time in Moscow and St. Petersburg

A large aurora region formed over Russian territory on the night of May 10. The special thing is that they appeared in the sky of St. Petersburg and Moscow.

This phenomenon appeared due to a very strong magnetic storm at levels G4 and G5. According to astronomy researchers from the Institute of Space Research, Russian Academy of Sciences, the magnetic storm started on the evening of May 10, causing a large area of Russia to be engulfed in a plasma cloud. The speed of the solar wind nearly doubled, from 400km/s to 700km/s. The plasma density has increased about 30 times leading to the formation of auroral regions.

The aurora borealis is an amazing natural phenomenon that usually only appears in Murmansk province and this locality is currently a favorite tourist destination for many Russians.

According to scientists, G1 level magnetic storms are considered the weakest, hardly affecting the operation of electrical equipment. Level G3 is a strong storm, directly affecting the electrical system and disrupting satellite positioning and radio communication activities. The maximum level is G5, which can cause large-scale problems with the power grid and seriously affect the operation of satellites and radio communications.
