When a coronal mass ejection slams into Earth’s magnetic field hard enough to register as a G3 storm on the five-level NOAA scale, the effects reach well beyond colorful skies. Grid operators face pressure to adjust voltages on high-voltage transmission lines,

A geomagnetic storm watch has been issued, raising the possibility of the northern lights becoming visible across portions of the northern United States over the next few nights, though Missouri has relatively low odds of seeing them.

The sun is spitting out solar flares, and those flares could be the sign of a geomagnetic storm brewing. NOAA’s Space Weather Prediction Center (SWPC) says multiple solar flares have occurred over the past 24 hours.

It's time to get outside tonight and look up at the sky. The Northern Lights should be visible in several states. It's all due to a G3 geomagnetic storm. These storms happen when there is a strong disturbance in the Earth's magnetic field.

Northern lights dazzled 23 U.S. states overnight, and forecasters say auroras could return tonight as lingering solar storm effects continue across North America.

While there is no physical damage to the planet, scientists with NOAA say storms can occasionally interfere with some technologies, depending on their strength.

A fast stream of solar wind could trigger G1 geomagnetic storm conditions overnight, boosting aurora chances across parts of the northern U.S.

Three coronal mass ejections were launched from the sun earlier this week and are expected to produce the stunning array of colors across the night sky.

Three solar flares erupted from the same sunspot region within a single 10-hour window on June 3, 2026, sending multiple coronal mass ejections toward Earth and prompting NOAA’s Space Weather Prediction Center to issue a G3 Strong Geomagnetic Storm Watch for June 4 and 5.
