First extreme solar storm in 20 years brings spectacular auroras worldwide

A powerful solar storm triggered spectacular aurora displays across the globe, with sightings reported in various parts of the world on May 11. The aurora borealis, also known as the northern lights, was particularly vibrant in Donegal, Ireland, which is one of the furthest points north where this phenomenon can be observed. Astrophysicists described the event as "historic" and "charged," with solar particles and emotions running high. The solar storm was triggered by a coronal mass ejection (CME) that struck Earth on Friday afternoon, upgraded to an "extreme" geomagnetic storm. This event is expected to be followed by more powerful CMEs on Saturday, potentially leading to even more spectacular aurora displays.
