The Northern Lights are seen above the Columbia River Gorge from Chanticleer Point Lookout in the early morning hours of May 11, 2024 in Latourell, Oregon. Places as far south as Alabama and parts of Northern California were expected to see the aurora borealis, also known as the northern lights from a powerful geomagnetic storm that reached Earth.

Earth is about to reach a place in space where geomagnetic activity is more likely—and that means stronger displays of the Northern Lights. Given that the sun is more active than ever since 2000, according to the latest figures, it could mean aurora displays at lower latitudes than usual, to 40 degrees north or even farther towards the equator.

That's what famously happened on May 10-12, when a global geomagnetic storm caused magnificent displays of colorful aurora as far south as Arizona and Florida.

When and where another G5 geomagnetic storm will materialize is anyone’s guess, but in September, there’s a bigger chance of any magnetic disturbance having a greater effect than is typical. That’s because there's a connection between Earth’s magnetic field and that of the solar wind. During a “solar maximum”—thought to be around about now—that goes double.

Data from the British Geological Survey backs up the claim that geomagnetic storms are more common during the spring and fall than in summer and winter—with late-September and early-April containing some of the most geomagnetically active days of the year.
