History

Historical Context

The Carrington Event, occurring from September 1-2, 1859, marked the largest geomagnetic storm on record, disrupting telegraph systems across Europe and North America. Observed by Richard Carrington, this solar storm caused auroras visible as far south as the Caribbean. Today's anticipated G3 geomagnetic storm highlights the ongoing significance of solar activity on modern technology and the need for infrastructure resilience against such events.
