Fast technology December 4 news, according to the forecast of the China Meteorological Administration, due to the combined influence of the solar coronal hole high-speed solar wind and the solar coronal mass ejection (CME),A small to moderate geomagnetic storm is possible today (December 4).
As a typical solar eruption activity, CME is driven by the powerful magnetic field of sunspots, hundreds of millions of tons or even trillions of tons of coronal matter is thrown out at a high speed of hundreds to thousands of kilometers per second, forming an explosion-like shock wave.
The shockwave travels rapidly throughout the solar system, and after being bombarded by it,Significant changes in the direction and size of the Earth's magnetic field occur in what are called geomagnetic storms.
So what are the effects of geomagnetic storms on humans?
The beautiful auroras that usually accompany magnetic storms,On December 1 and 2, the Earth experienced a 3-hour geomagnetic storm, a 3-hour moderate geomagnetic storm, and a 9-hour small geomagnetic storm, including auroras in many parts of China.
In addition to the beautiful aurora, magnetic storms can have many effects, such as potentially affecting the propagation of radio waves, interfering with ground communications and satellite signals,This can affect the accuracy of navigation satellite systems, as well as the signal quality of mobile phones and satellite television.
Magnetic storms can also affect satellite and aviation flights, creating greater flight resistance to spacecraft in space and threatening the safety of spacecraft in orbit.
However, magnetic storms have almost no effect on the health of ordinary people.
