What is a geomagnetic storm?
The Earth’s magnetic field is like a protective shield. When the sun “loses its temper”, it releases coronal mass ejections, which interact with the Earth’s magnetic field, causing violent disturbances in the Earth’s magnetic field, forming a geomagnetic storm.
Wide-ranging impact
Communication and navigation: Positive disturbance of the ionosphere over China, flickering of the ionosphere in many places in the south, absorption of polar auroras, low-frequency bands of high-frequency communications in high-latitude areas affected, interference of satellite signals causing degradation of communication quality, and deviation of positioning accuracy of navigation systems of aircraft, ships, and cars.
Satellites and space stations: Changes in the magnetic field cause deviations in satellite attitudes, and electronic components are bombarded by high-energy particles, causing failures or performance degradation; the density of air at high altitudes increases, and spacecraft such as space stations are subject to large air resistance, and their speed and altitude decrease.
Human biology: The direct impact on the human body is weak, but sensitive people may suffer from anxiety and insomnia; animals that rely on geomagnetic navigation, such as homing pigeons, some fish and marine life, are affected in their migration and navigation capabilities.
Power transmission: Although there are no reports of large-scale failures, there are potential risks, which may affect transformers, transmission lines and other equipment.
Natural landscape: Gorgeous auroras appear in Mohe, Heilongjiang, with prominent green light bands, and red and purple interweaving, which last for a long time. Xinjiang, Inner Mongolia and other places have also become popular viewing spots.
Countermeasures
Scientists can monitor and warn, and individuals should pay attention to and reduce the use of equipment and outdoor activities that rely on the ionosphere. Infrastructure and technology systems need to formulate emergency plans, such as power reinforcement equipment, additional backup power supplies, and communication optimization network structure.
