A powerful geomagnetic superstorm is a once a generation event, happening once every 20-25 years. Such an event transpired on the night of May 10/11, 2024, when an intense solar storm slammed into the Earth’s protective magnetic sheath. Now, a recent study shows just how intrusive that storm was, and how long it took for the Earth’s plasma layer took to recover.

by Riko Seibo Tokyo, Japan (SPX) Nov 21, 2025 Researchers have detailed how a geomagnetic superstorm on May 10-11, 2024, shrank Earth's plasmasphere, a protective zone of charged particles, to just one-fifth of its normal size. The event, named the Gannon storm or Mother's Day storm, was the most powerful in over twenty years. Led by Dr. Atsuki Shinbori at Nagoya University's Institute for Space-Earth Environmental Research, the team used data from the Arase satellite, which was ideally positioned to observe the plasmasphere's compression and subsequent slow recovery.

Last year, the most violent geomagnetic storm to strike Earth in over two decades did more than disrupt GPS systems and internet connections. According to a study published today in the journal Earth, Planets and Space, superstorm Gannon also squeezed the planet’s protective layer of ionized particles to one-fifth its normal size.
