Geomagnetic storm triggers auroras in Mexico
Raportoinut AI AI:n luoma kuva
A severe geomagnetic storm, triggered by a solar coronal mass ejection, lit up the skies with auroras borealis in Mexico and the northern hemisphere on November 11, 2025. Images of green and purple colors were captured in states like Zacatecas and Nuevo León, while in the United States they were seen in Colorado and Kansas. UNAM and NOAA experts indicate that effects will continue more faintly on November 12 and possibly on the 13th.

New data from the European Space Agency's Swarm satellites reveal that the South Atlantic Anomaly, a weak spot in Earth's magnetic field, has grown by nearly half the size of continental Europe since 2014. A region southwest of Africa is weakening even faster in recent years. This expansion highlights unusual activity in Earth's molten outer core.
On September 11 and 12, 2025, astronomers observed significant filament activity on the Sun, with plasma lifting off in the northern and southeastern regions. Despite low flaring activity limited to C-class flares, the events provided a spectacular display of solar dynamics. This activity highlights ongoing solar monitoring efforts amid a period of relatively calm sunspot behavior.
