Outline
What is the problem?
Why should we care?
What can we do about it?

The Sun undergoes an 11-year activity cycle.
Solar activity cause solar flares and coronal mass ejections (CME).
During these events, high energy particles are ejected to the solar system.
Some of them might hit Earth…

Satellites stop functioning.
Power grids fail.
Critical services become unavailable without electricity and satellites.
Major global crisis could take place!

Carrington observed a solar flare coming from a sunspot
Several days later Earth experienced the strongest geomagnetic storm ever recorded
1859 –Carrington Event

On March 13th, 1989, a large solar storm hit Earth.
Geomagnetically induced currents destroyed transformers in North American power grid.
The power grid failed in Quebec area for over 9 hours, leaving 5-6 million people without electricity.
The associated damage is estimated between 4-10B$.

Strong solar storm hit Earth on October 2003.
New York area suffer from blackout for more than 30 hours, affecting 50-60 million people.
The associated damage is 4-20B$.
Space missions experience damage and faults (deep space and near Earth).

The above mentioned are “low frequency high impact” events.
High frequency low impact storms occur all the time and cause minor failures, some not even associated with space weather.
In the meantime…

The world today depends on electricity and computers to function.
A Carrington like event today can destroy satellites, power grids, computers and critical infrastructure.
The world, as we know it, will disappear and economy might be thrown back 100 years!
Carrington today?

Learn more about solar physics and space weather• Study data from other stars (e.g. Kepler data)• Improve solar observation capabilities
Prepare satellites for extreme space weather (shielding, redundancy, safe modes…)
Rethink human spacecraft design
Create space weather detection and forecasting network
