A strong geomagnetic storm is pushing the northern lights much farther south than usual this week.

Historically, March brings some of the strongest auroral activity. The upcoming spring equinox is the primary driver.

Around the equinox, Earth's magnetic poles tilt into a highly favorable alignment with the incoming solar wind.

This specific seasonal geometry opens temporary 'cracks' in our planet's protective magnetic shield.

Through these magnetic gaps, highly charged particles from the sun stream directly down into our upper atmosphere.

As solar particles smash into atmospheric oxygen and nitrogen, they release energy as brilliant bursts of colorful light.

This spring's vivid displays are further amplified because our sun is currently approaching its period of maximum energetic activity.

Catching the aurora requires a dark sky with zero light pollution. The best viewing window is usually between 10 p.m. and 2 a.m.

Monitoring geomagnetic storms isn't just for stargazers. It helps us protect vulnerable power grids and satellite communications.
