In an exceptional event, the Aurora Australis, or southern lights, were sighted over Brazil on January 19th, a rare occurrence far from its usual high-latitude viewing zones. Captured by photographer Eliane Strey in Rio Grande do Sul, the vibrant display of green and pink lights was caused by a severe geomagnetic storm, reaching at least G4 intensity.
This storm, triggered by powerful solar flares and coronal mass ejections (CMEs), significantly expanded the auroral oval, pushing it towards the equator. While auroras are caused by charged solar particles interacting with Earth's atmosphere, intense storms can lead to disruptions in communication, GPS, and even power grids.
