According to the National Space Weather Monitoring and Warning Center, from midnight to 11, 2024, there will be a mega-geomagnetic storm on the earth, with a maximum level of super-geomagnetic storm. At that time, due to the influence of geomagnetic storms, the ionosphere in most parts of the continent will be disturbed, and a rare aurora phenomenon will appear. Radio communications will be affected, and the density of the atmosphere in the Earth's upper space will increase significantly.
According to netizens in Xinjiang, Heilongjiang and other places, on the evening of May 10, a large number of rare purple-red and pink aurora appeared in the sky over the Altay region of Xinjiang. In the early morning of May 11, netizens in the Daxinganling area of Heilongjiang Province photographed a large pink aurora on their balconies, dancing beautifully against the background of the clear blue sky. At the same time, netizens in New Zealand, Canada, the United Kingdom, Germany, Switzerland, Hungary, the United States, Cuba and many other countries also witnessed the purple, red, and green aurora floating in the sky.
Geomagnetic storms are caused by the ejection of high-energy charged particles into cosmic space by the solar corona. When these charged particles enter the earth's magnetic field, they will interact with the earth's magnetic field and the upper ionosphere, resulting in the phenomenon of air luminescence over the high latitudes of the North and South poles. When the level of the local magnetic storm is very high and the number of high-energy charged particles is large, the range of auroras will extend from high latitudes to low latitudes, so that many areas that would not otherwise have aurora phenomena will also appear. This is how the rare purple-red aurora triggered by the extra-terrestrial magnetic storm in Xinjiang and Heilongjiang was produced.
