Sun Triggers Strongest Solar Radiation Storm in Over 20 Years The Sun has unleashed its strongest solar radiation storm in more than 20 years, sending high-energy charged particles toward Earth and triggering disruptions in GPS systems for some aircraft. The rare event, classified as the most intense since the 2003 “Halloween storms,” also coincided with a severe G4 geomagnetic storm caused by a coronal mass ejection, leading to bright auroras across Europe and heightened monitoring of satellite

A solar storm is a massive eruption of energy and charged particles from the Sun that, when directed toward our planet, can cause a significant disturbance in the Earth's magnetic field known as a geomagnetic storm. These events typically begin when twisted magnetic fields on the Sun snap and reconnect, releasing a burst of radiation called a solar flare or an enormous cloud of plasma known as a coronal mass ejection (CME). As these particles reach Earth, they smash into the magnetosphere—our in
