Power Blackout Caused by Space Weather Storm
In 1989 a space weather storm caused an electrical blackout over a large area. Six million people in eastern Canada lost electrical power for 9 hours or longer.
In March 1989 a large space weather storm struck Earth. The storm generated strong electrical currents in our atmosphere. Some of that electricity caused currents to flow in wires in our electrical power system. That extra surge of electricity damaged some kinds of equipment. A major transformer was destroyed. That caused the whole electrical system to "go down". Lots of people lost power for many hours.
The blackout in Canada cost a lot of money and was dangerous. Scientists are trying to learn how to predict big space weather storms better. That could help prevent blackouts like the one in Canada.
