The space weather alert was triggered by an M8-class solar flare from sunspot 4299 on December 6, which immediately preceded the incoming CME.

The wind from the sun is predicted to be much more powerful, bringing auroras that will probably light up the whole area of high-latitude places. Among U.S. residents, Alaska, Washington, North Dakota ...

A powerful M8.1 solar flare sent a full-halo coronal mass ejection toward Earth, and scientists expect it to trigger strong G3 geomagnetic storm levels on Tuesday. Forecasts show the Kp index rising ...

Solar activity could cause stronger-than-usual auroras, making the northern lights visible in more U.S. regions than usual.

Fast solar wind and possible CME activity may increase northern lights chances over Christmas, mainly across high-latitude regions ...

A strong geomagnetic storm may hit Earth on Monday night after the sun released a powerful M8.1 solar flare on Saturday. The NOAA Space Weather Prediction Center issued a geomagnetic storm watch, ...

The Sun exhibited unpredictable behavior with two strong solar flares in late November and early December 2025. These events, ...

(CNN) — For the first time, astronomers say they have spotted a giant explosion released by a star beyond our solar system. The eruption was similar in some ways to those unleashed by our sun, such as ...

"Ultimately, this work may help scientists better predict the impact of space weather across the solar system on longer ...

Aditya-L1 and U.S. satellites uncover why the May 2024 solar storm behaved unusually, revealing significant magnetic field dynamics.

India's Aditya-L1 observatory played a crucial role in deciphering the unusual behavior of the May 2024 solar storm, the strongest in two decades. The collaboration with US satellites helped map ...
