Enhanced monitoring and forecasting of space weather are crucial to safeguard our satellite technology.

History

Historical Context

In March 1989, a severe geomagnetic storm caused a nine-hour blackout in Quebec, impacting six million people and resulting in over $6 million in losses for Hydro-Québec. This event underscored vulnerabilities in electrical systems, prompting ongoing research into the risks geomagnetic storms pose to satellites. Today, advancements in satellite design aim to mitigate these risks and protect critical technology from solar events.
