AI Summary

In May 2024 Earth endured its strongest geomagnetic storm since the 2003 Halloween events, producing vivid aurorae worldwide and briefly disrupting GPS signals used by agricultural equipment. Satellite data showed the storm caused a sudden, dramatic loss of highly energetic electrons from the outer Van Allen radiation belt. Researchers led by Xingzhi Lyu performed the first comprehensive analysis of the rapid electron transport that produced the depletion. Their findings, published in AGU Advances, aim to improve future space‑weather forecasting.
