An "extreme" G5 geomagnetic storm reached Earth on Friday, NOAA's Space Weather Prediction Center said, after issuing a watch earlier in the day warning of the potential for a severe impact.

(NEXSTAR) — On Friday night, the most significant G5 geomagnetic storm since 2003 hit Earth — causing several coronal mass ejections, or CMEs — and allowing many across the U.S. to see ...

Aurora chasers, keep your eyes on the skies this weekend as northern lights might be possible at mid-latitudes.

Northern lights may once again be visible deep into mid latitudes tonight as geomagnetic storm conditions continue to wreak havoc with Earth's magnetic field.

NOAA classifies geomagnetic storms on a G-scale, with G5 being the most severe. The current watch is for a G2-class storm, which is considered moderate. How dangerous are solar storms?

Colorful auroras could be visible in areas of the United States such as Alabama and Northern California — much farther south than they typically appear — on Thursday evening due to a powerful solar ...

Historically, G4 storms are common during a solar cycle, but G5, or extreme geomagnetic storms such the one that occurred on May 10, are incredibly rare, Dahl said. This new storm has a 25% chance ...

At high altitudes, geomagnetic storms can also result in stunning displays of light called auroras. The NOAA Space Weather Prediction Center ranks geomagnetic storms on a scale of G1 to G5.
