This year, all signals will be unstable, including the magnetic field of humans, which will also weaken. Solar flares are one of the most intense activities on the sun, with energy equivalent to billions of hydrogen bombs exploding. According to the energy released in soft X-ray bursts, they are classified into five categories: A, B, C, M, and X, with energy levels differing by a factor of ten. An X1.0-class flare is 100 times stronger than a C1.0-class flare. What is the impact of solar activity on us?

Solar activity can cause solar winds and changes in the Earth's space environment, resulting in space weather that may lead to space weather disasters and affect the safety of satellites and spacecraft, as well as aviation, communication, navigation, and other fields. Geomagnetic storms can cause unstable power supply and GPS signal failures.
