The strongest solar storm in over 20 years continues, and a major boost on Wednesday afternoon could elevate this aurora experience to once-in-a-lifetime.

Dazzling auroras delighted sky-gazers Tuesday night, even in southern US states such as Florida where they rarely make an appearance — and more colorful displays began appearing Wednesday as solar storms unleashed by the sun reached Earth.

The British Geological Society is warning that the Earth is about to get hit by the most powerful solar storm in over two decades.

The northern lights could be visible from a much larger portion of the northern United States than usual on Tuesday night and Wednesday morning, according to the National Oceanic and Atmospheric Administration, as X-class flares from the sun days earlier impact the Earth.
