The National Space Weather Monitoring and Warning Center issued a red warning for geomagnetic storms at 09:00 on the 11th: geomagnetic storms will occur from 23:00 on May 10, 2024, Beijing time, and the maximum level will reach the level of ultra-geomagnetic storms (Kp=9), and it is expected that the magnetic storm process will continue in the next 24 hours, and geomagnetic storms may still occur in the future. Under the influence of geomagnetic storms, the ionosphere will be disturbed in most parts of the continent, and shortwave communication and navigation and positioning will be affected to varying degrees. A significant increase in the density of the upper atmosphere will lead to an increase in the orbital attenuation of low-orbit satellites.
