The risks our technology-reliant civilization may face in the event a severe geomagnetic storm hits earth, and who monitors space weather activity for Canada.

Millions people across North America witnessed that first hand in early May, when a vibrant and widely visible aurora lit up the night sky., we looked into historic geomagnetic storms that created equally, if not larger, auroras, that caused disruptions to critical infrastructures like they Hydro Quebec power grid in 1989.

When scientists first see a solar flare or CME, to when they can assess the impact the storm could pose on critical infrastructure, becomes a bit of a waiting game."By the time the solar material is close enough to assess, you have 30 minutes, and that's a very short time to respond."David Boteler is head of the space weather group at Natural Resources Canada, and spends his time researching the hazards that come from geomagnetic disturbances.

"It showed us how dependent we were on this technology, and just the widespread effects it has on every element of our life." The May 2024 event actually served as an important opportunity for New Zealand to test out its Solar Tsunamis program. At Natural Resources Canada, when Reiter or other members of the space weather team detect what could be a major geomagnetic storm, they first notify members in their departments' chain of management so they have an awareness of an ongoing space weather event.
