China Meteorological Administration issued geomagnetic storm warning: satellite navigation equipment error may increase

Thank CTOnews.com netizens "see" for the clue delivery! CTOnews.com news on December 1, according to CCTV news, according to the China Meteorological Administration Space Weather Center monitoring, December 1 and 2, geomagnetic storm activities may occur in China. Among them, more than moderate geomagnetic storms or even geomagnetic storms may occur on December 1, and geomagnetic activity is expected to continue until December 2.

Under this influence, the altitude of the orbit of the space station may drop due to atmospheric drag, the error of satellite navigation equipment may increase, and aviation flight will face the double risk of deteriorating communication environment and cross-polar radiation. For the public, especially homing pigeon players and auroral enthusiasts, we should always pay attention to space weather information in the next few days.

According to CTOnews.com, a magnetic storm is a strong disturbance that lasts for more than ten to dozens of hours in the whole earth's magnetosphere. It is caused by solar activity. When the sun ejects a large number of charged particles into the earth's atmosphere, it causes ionospheric disturbance and sharp and irregular changes in the intensity and direction of the geomagnetic field.

When magnetic storms occur, the disturbance intensity is the highest in the polar regions, which is often accompanied by auroras. Due to the ionospheric disturbance caused by the magnetic storm, the radio waves used in normal communication cannot return to the ground; in serious cases, the shortwave radio communication is even completely interrupted, and the direction of the compass needle is also affected.
