Solar Superstorm Gannon crushed Earths plasmasphere to a record low

A massive solar storm in May 2024 gave scientists an unprecedented look at how Earths protective plasma layer collapses under intense space weather. With the Arase satellite in a perfect observing position, researchers watched the plasmasphere shrink to a fraction of its usual size and take days to rebuild. The event pushed auroras far beyond their normal boundaries and revealed that a rare negative storm in the ionosphere dramatically slowed the atmospheres ability to recover. These observation...
