According to the National Space Weather Monitoring and Warning Center of the China Meteorological Administration, geomagnetic activity may occur on March 24, 25 and 26, of which geomagnetic storms above moderate or even geomagnetic storms may occur on March 25, and geomagnetic activity is expected to continue until the 26th.
Under this influence, the space station may be dragged by the atmosphere to cause the orbital altitude to decrease, the positioning error of satellite navigation equipment to increase, aviation flight will face the dual risk of deterioration of the communication environment and radiation across the polar region, for the public, especially pigeon players and aurora enthusiasts, in the next few days to always pay attention to space weather information.
The coronal mass ejection (CME) process took place almost directly opposite the Earth, so that the eruption forms a circular surface, which is what we have previously referred to as a "total halo". The solar material ejected by such explosive activities is fast and covers a high degree of coverage relative to the Earth, which may cause relatively strong geomagnetic activity. From the point of view of watching the aurora show, aurora lovers will see a beautiful sight, and from another point of view, for the majority of carrier pigeon players, it is necessary to minimize adverse weather conditions and long-distance driving activities in the coming days.

On December 1, 2023, according to the early warning issued by the Space Weather Monitoring and Warning Center of the China Meteorological Administration, geomagnetic storms may occur on the mainland on December 1 and 2, of which geomagnetic storms above moderate or even geomagnetic storms may occur on December 1.
On the evening of December 1, red and green aurora appeared in Mohe Arctic Village, Heilongjiang Province. According to the official Weibo account of China's National Geographic Channel, on the evening of December 1, some netizens photographed the aurora in Huairou, Beijing, which is the second aurora image record in Beijing's history.
On the evening of December 1, Zhu Jin, a researcher at the Beijing Planetarium and editor-in-chief of the magazine "Astronomy Enthusiasts", said that the occurrence of auroras is caused by the flow of charged particles (solar wind) from the sun into the earth's magnetic field, and due to the action of the geomagnetic field, these high-energy particles turn to the polar regions, and the luminescence phenomenon caused by the collision of atoms in the upper atmosphere at high altitude in the areas near the north and south poles of the earth.
Zhu Jin said that although the aurora is common in high magnetic latitude areas, if the geomagnetic storm is particularly strong, the range of the aurora will expand, and it is recorded that when the geomagnetic storm is strong, the aurora can be seen even in the equatorial region. Therefore, it is possible to see the aurora in the Beijing area at 40° north latitude.
According to Zhu Jin's recollection, he saw the aurora in Xinglong, Hebei Province in 2003. At that time, there were also reports of aurora observations in Pinggu, Beijing.
As for why auroras also occur in the middle and low latitudes, Zhu Jin said that under normal circumstances, when the sun's high-energy charged particles arrive near the earth, the earth's magnetic field will direct them to the earth's poles. However, if the high-energy charged particles of the sun reaching the earth are particularly strong, and the interaction with the earth's magnetic field produces a particularly strong geomagnetic storm, some high-energy charged particles will enter the atmosphere in the middle or low latitudes, and it is possible to produce auroras in the middle and low latitudes.
