History

Historical Context

The Carrington Event, occurring on September 1-2, 1859, was the most intense geomagnetic storm recorded, caused by a coronal mass ejection from the Sun. It disrupted telegraph systems across North America and Europe, igniting fires and delivering shocks to operators. Today, NOAA forecasts a G2 geomagnetic storm, highlighting the ongoing relevance of solar activity and its potential impact on modern technology.
