Overview

• Latest satellite data show the AMAS has intensified, shifted about 20 kilometers westward and begun splitting into two distinct sectors
• The weakened geomagnetic field allows increased penetration of charged solar particles, raising radiation exposure over parts of South America and the South Atlantic
• Space agencies including NASA, ESA, NCEI, BGS and Argentina’s Agencia Espacial Nacional have adjusted satellite trajectories and equipment orientations to reduce exposure
• No direct human health risks have been identified, but heightened radiation threatens satellites, radio transmissions, navigation and internet infrastructure
• Missions such as ESA’s Swarm and NASA’s ICON are providing real-time measurements to refine models and inform future mitigation strategies
