Increased solar activity causes auroras that dance around Earth’s poles, known as the northern lights, or aurora borealis, and southern lights, or aurora australis. When the energized particles from coronal mass ejections reach Earth’s magnetic field, they interact with gases in the atmosphere to create different colored lights in the sky.

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 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.

Northern Lights may dazzle again tonight as a severe geomagnetic storm reaches peak intensity across regions. Follow live.

The predicted speed of the third coronal mass ejection in the series was the highest he'd ever seen: about 870 miles per second. Conde said that although the best auroras were forecast for Tuesday and Wednesday, the lights could continue to shine for the next few days.

The International Space Station's three Russian cosmonauts were instructed to spend a night in a laboratory module to shelter from radiation during a solar storm.

Millions across the U.S. and Europe witnessed rare, colorful displays of the northern lights on Tuesday and Wednesday after three bursts of plasma from the Sun triggered a powerful geomagnetic storm.

Very tame November weather will continue for Montana but a severe geomagnetic storm will hit Earth the next few nights with the potential for significant aurora borealis.
