An M3-class solar flare that lasted about 3 hours created a massive coronal mass ejection. The Solar Dynamics Observatory ...

After witnessing the array of Northern Lights as far south as Colorado, we discuss how Coronal Mass Ejections (CME) are ...

The sunspot that caused the flare and the CME (AR4046) is moving around the sun to face our planet, meaning that if it releases any more flares or CMEs, they will likely hit the Earth head-on.

10. X3.38 — Feb. 9 This X3.38 flare, which occurred over the southwestern edge of the sun, would have measured much higher if most of the emission had not been blocked by the edge of the sun.

The latest solar flare follows an M-class one, the second-highest on the scale, that occurred days earlier on June 15. It caused a shortwave radio blackout across North America, with a loss of signal ...

That flare was indeed followed by a CME that struck Earth and caused an intense geomagnetic storm, which was recorded by astronomers at the time, and is now known as the Carrington event.

In May 2024, the largest solar flare since 2017 was detected, ranking at an X-8.7 magnitude. Then in 2025, a flare May 13 was classified as an X-1.2 , and another the next day was listed as an X-2 ...

Following a solar flare and associated coronal mass ejection on the sun's surface late Friday, NOAA's Space Weather Prediction Center issued a geomagnetic storm watch for Sunday and Monday, June 1 ...

The first CME scheduled to reach our planet on New Year's Eve is likely associated with a recent M2 solar flare. The CME left the sun on Sunday at 1 a.m. ET, according to SpaceWeatherLive.

Using the European Space Agency’s Characterizing Exoplanets Satellite (CHEOPS) telescope, a team of astronomers ...
