A massive solar storm, the strongest in over 20 years, hit Earth, causing stunning auroras and raising concerns about satellite and power grid disruptions. The storm, triggered by several coronal mass ejections from the Sun, was upgraded to an "extreme" geomagnetic storm. Social media was abuzz with photos of the auroras from various parts of the world. Authorities warned satellite operators, airlines, and power grids to take precautions. The storm's effects are expected to be mainly felt in the planet's northern and southern latitudes.
