The National Space Weather Monitoring and Warning Center issued a red warning for geomagnetic storms at 9 o'clock on the 11th: geomagnetic storms will occur from 23 o'clock 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.
Geomagnetic storm is the "friction" between the magnetic field of the solar wind and the earth's magnetic field, and when the solar wind "hits" the earth, it will trigger a geomagnetic storm, bringing about changes in the direction and magnitude of the earth's magnetic field.
Geomagnetic storms will have an impact on satellite navigation equipment, which may increase its positioning error, but it will have little impact on the daily use of navigation and other functions by the public.
For example, for aviation flights, the radiation dose for a daily domestic flight flight is about 2 to 6 microsieverts, and the radiation dose for international flights across the polar regions is slightly higher, about 50 microsieverts, which is a dose of tens to hundredths of the national security standard. When a geomagnetic storm or solar proton event occurs, the airborne radiation dose increases, but the impact of a single flight is not significant.
There are rumors that geomagnetic storms can cause insomnia, nervousness, anxiety, etc., and some people say that ultraviolet rays are stronger during geomagnetic storms, so you should do a good job of sun protection.
But that's all nonsense. Geomagnetic storms have little impact on ordinary people, and unless you're flying across the polar regions, you're still looking for problems outside the sun for insomnia. In addition, geomagnetic storms have nothing to do with the intensity of the sun's ultraviolet rays.
The National Space Weather Monitoring and Warning Center also said that geomagnetic storms will not affect physical health. So the rumors can be put to rest.
