Story summary

Two significant coronal mass ejections (CMEs) from the Sun on November 11, 2025 followed X-type solar flares and triggered moderate geomagnetic disturbances on Earth.
The European Space Agency (ESA) said the CMEs could affect satellites, power grids, and navigation systems, but they pose no direct biological risk to humans.
A more powerful X5.1-class flare was observed.
The CME from that flare was expected to reach Earth by November 12 or 13.
