The South Atlantic Anomaly, a weak spot in Earth's magnetic field, expands over the Atlantic Ocean

Earth's magnetic field has a weak spot over the Atlantic that has grown significantly since 2014. This South Atlantic Anomaly, a region of weakened magnetic field strength, has expanded by an area nearly half the size of Europe. Satellites passing through this anomaly face increased radiation, potentially causing malfunctions. The anomaly's behavior is complex and still not fully understood, with scientists observing specific changes southwest of Africa.
