Summary

Story summary

A series of coronal mass ejections will boost aurora visibility across the Northern Hemisphere, especially on October 16, 2025.
The UK Met Office forecasts Northern Lights may be seen as far south as Yorkshire.
The National Oceanic and Atmospheric Administration (NOAA) forecasts aurora visibility in northern U.S. states from New York to Idaho.
The first CME will reach Earth on October 15, 2025, with geomagnetic activity at G2 levels.

History

Historical Context

The Carrington Event of September 1-2, 1859, was the most intense geomagnetic storm recorded, caused by a coronal mass ejection from the Sun. It produced spectacular auroras visible as far south as the Caribbean and disrupted telegraph systems across the U.S. and Europe. Understanding such solar phenomena is vital today, as similar storms can threaten modern electrical infrastructure and satellite operations.
