Space weather alert!
On 11 November 2025, an intense solar flare was observed from Earth, with a peak around 10:04 UTC. This was followed less than an hour later by a coronal mass ejection (CME) – a large burst of charged particles – with an initial speed estimated to be around 1500 km/s. On 12 November, at 18:50 UTC, the CME associated with this solar flare arrived at Earth.
The ESA-led Solar Orbiter mission was flying close to Earth at the time and caught the Sun’s outburst on camera. This video shows data from the spacecraft’s Extreme Ultraviolet Imager (EUI) instrument recorded on 9–12 November 2025.
EUI can see the light coming from million-degree charged particles in the Sun’s outer atmosphere (the corona). On 11 November, an active region in the Sun’s corona lights up, and the surrounding space fills up with glowing particles flung out from the Sun.
The data shown here combines the light detected at two ultraviolet wavelengths: 17.4 nanometres (yellow) and 30.4 nanometres (red).
