Powerful Geomagnetic Storm Triggers Stunning Aurora Displays
12 Nov
Summary
- About 20 U.S. states saw the northern lights on Nov. 11
- Geomagnetic storm reached severe G4 levels, affecting power grid and GPS
- Colorful auroras visible as far south as Florida
On November 11, 2025, a powerful geomagnetic storm arrived in Earth's atmosphere, triggering stunning displays of the northern lights across much of North America. According to the National Oceanic and Atmospheric Administration (NOAA), about 20 U.S. states caught a glimpse of the vibrant aurora borealis, with the colorful lights visible as far south as Florida.
The geomagnetic storm reached severe G4 levels at 8:20 PM EST on November 11, and the Space Weather Prediction Center warned that the event could continue to affect power grids, communications, and GPS signals on November 12. The storm was caused by a series of coronal mass ejections from the sun earlier in the week, which sent bursts of solar material and magnetic fields hurtling towards Earth.
As the sun's charged particles interacted with Earth's atmosphere, they triggered the mesmerizing aurora displays, with oxygen molecules producing the characteristic green and red hues, and nitrogen creating blue and reddish tones. Social media feeds quickly filled with stunning photos of the dancing lights across the northern horizon.
