On December 15, 2006 (October 25, 2006 in the lunar calendar), a major magnetic storm occurred on the earth. On December 15, 2006, a major magnetic storm occurred on the earth. The National Space Weather Monitoring and Early Warning Center released a report on the 15th, saying that a major magnetic storm appeared on the earth on the 15th, and a major magnetic storm may occur again on the evening of the 16th. The major magnetic storm may have some impact on artificial satellites and Earth's communication and navigation systems. According to Le Guiming, a researcher at the Space Weather Office of the National Satellite Meteorology Center, an X3.4-level solar flare broke out at 10:40 on the 13th, Beijing time, accompanied by a coronal mass ejection (CME). After these CMEs arrived at the earth, the earth occurred in the early morning of the 15th. A major magnetic storm occurred. Another X1.5-level solar flare broke out at 6:15 Beijing time on the 15th, also accompanied by CME. Affected by this solar flare, the flow of high-energy protons from the sun increased again. The proton event is expected to end later on the 15th or 16th. These CMEs may reach Earth on the evening of the 16th, when major magnetic storms may occur again. Le Guiming said that large magnetic storms can change the attitude of artificial earth satellites, for example, they can change the detection direction of remote sensors on satellites. Large magnetic storms can also affect positioning, navigation and short-wave communications, but generally do not affect mobile phones. The additional current generated by a large magnetic storm will have a certain impact on the power system. In addition, when a large magnetic storm occurs, the pigeons released will get lost and cannot return home because the pigeons fly along the magnetic field lines, and the large magnetic storm will change the direction of the magnetic field lines. wonders of the universe
