NOAA: Strongest Solar Storm in 20 Years Hits Earth, Northern Lights Aurora Borealis May Seen Over Florida Tonight

ORLANDO,  Florida – The NOAA Space Weather Prediction Center confirmed an S4 radiation storm—the strongest since October 2003—triggered by an X1.95 flare from sunspot region 4341, followed by a fast coronal mass ejection that sparked G4 geomagnetic conditions starting Monday afternoon around 2:38 p.m. EST.

Astronauts on the International Space Station are sheltering in shielded areas, while satellites and high-altitude flights face radiation risks, ABC News reports, though no power grid issues have appeared.

Skywatchers from northern U.S. states to Alabama and Florida can spot vibrant northern lights tonight, best away from city lights after dark, according to Forbes.
