OREANDA-NEWS. As stated on the website of the Laboratory of X-ray Astronomy of the Sun of the Physics Institute of the Russian Academy of Sciences, a cloud of plasma ejected from the Sun on December 7 will cover the Earth on Wednesday afternoon, which will lead to geomagnetic changes, radiation effects on satellites and will make it possible to see the northern lights at the latitude of St. Petersburg and Murmansk.

The published report says that for the first time in several years, geomagnetic disturbances caused by a solar flare are expected on Earth on the night of December 9-10, 2020. The reason will be the masses of solar matter ejected from the atmosphere of our star on the evening of December 7 during the outbreak that occurred here and is currently propagating towards the Earth.

Scientists believe that the arrival of the first clouds of solar plasma in near-Earth space is expected at 3-4 o'clock in the morning on December 9, and the main core of the ejection will reach the planet's orbit closer to midnight. In total, the planet Earth will plunge into solar matter for about a little more than a day until mid-December 10.

The impact from the plasma cloud will consist in a sharp increase in the radiation load on space vehicles, as well as fluctuations in the magnetic field near the Earth's surface.

The message says that the outburst that occurred on the Sun on December 7 belongs to the class "C", that is, to the minimum. Before the middle class "M", the flash lacked a third of the power. It is noted that outbreaks of the X20 level are record-breaking in the history of observation, which exceed the current event by more than 200 times in power.
