Solar storm lights up auroras from Europe to Southern California, 23-year radiation record broken

A powerful solar radiation storm triggered by an X-class solar flare and a CME struck Earth, producing widespread auroras across Europe and parts of North America, with sightings as far south as Southern California. The storm peaked at G4 (severe) on the geomagnetic scale per NOAA’s SWPC. While dramatic, it wasn’t the strongest in two decades (the 2024 Mother’s Day event held that distinction), but it did set a 23-year record for solar-radiation storms.

Sun Unleashes Earth’s Biggest Radiation Storm in Two Decades

NOAA’s Space Weather Prediction Center says Earth is being hit by an S4 solar radiation storm—the largest in more than 20 years—driven by high-speed charged particles from the Sun that could affect satellites, space launches, and polar aviation. Astronauts aboard the ISS are advised to stay in shielded areas, while geomagnetic activity has sparked auroras worldwide.

Severe Solar Radiation Storm Triggers Space Weather Alerts

NOAA reports a rare S4 (Severe) solar radiation storm in progress as of January 19, 2026, with GOES-19 measurements indicating intensification. The storm poses increased radiation exposure risks for astronauts and polar flights, potential satellite and space-launch impacts, and possible loss of over-the-horizon HF communications in polar regions; agencies including airlines, FAA, NASA, FEMA, and NERC have been notified as conditions evolve.

"Sun Unleashes Powerful Solar Flare, Causing Radio Disruptions and Radiation Storm"

A strong X-class solar flare emitted from the Sun on Friday caused a solar radiation storm on Earth, with charged particles accelerated near the Sun arriving at over 10 times the normal background amount. The storm, classified as moderate (level S2 out of S5), was expected to peak on Saturday morning. While powerful solar flares can cause radio blackouts in polar regions and pose risks to space launches and spacecraft, most people do not need to be concerned as the energetic particles do not reach low enough into Earth's atmosphere to affect the public. NASA's Solar Dynamics Observatory captured the X3.3 flare, and more sunspots are expected as the Sun approaches the solar maximum of Solar Cycle 25.
