On May 11, the National Space Weather Monitoring and Warning Center issued a red warning for geomagnetic storms at 09:00 on May 10, 2024, Beijing time, a geomagnetic storm occurred at 23:00, and the maximum level reached the level of super-large geomagnetic storm (Kp = 9). It is expected that the process of magnetic storms will continue in the next 24 hours, and large geomagnetic storms may still occur in the future. Affected by geomagnetic storms, the ionosphere will be disturbed in most parts of China, and short-wave communication and navigation and positioning will be affected to varying degrees. The density of the upper atmosphere will increase significantly, which will lead to increased attenuation of low-orbit satellites.
