History

Historical Context

The Carrington Event, occurring on September 1-2, 1859, was the most intense geomagnetic storm recorded, resulting from a coronal mass ejection. It caused widespread auroras and disrupted telegraph systems across North America and Europe, with operators experiencing sparks and fires. Today's G2 geomagnetic storm serves as a reminder of the potential impacts solar events can have on modern technology and infrastructure.
