The intention

We intend to dedicate the day to discussions concerning geomagnetically
induced currents (GICs), caused by the space weather. The presentations
and discussions will focus on the following topics.

• How can GICS affect power systems and other long conductors?
• What actions can and should be taken to mitigate GIC effects?
• Joint efforts in international projects (SUNBURST, Space Weather Month)
• What experiences, knowledge and data do we have at hand?
• A Nordic GIC Network.

(Space Weather refers to solar conditions that influence earth's atmosphere,
technological systems and human health. )

 Agenda

 16.30 Summary and planning for the future
 

September 24, follow-up discussions

1. Summary of Thursday , conclusions, what should be done and by whom.

2. Clarify which GIC predictions/forecasts can be done. What kinds are needed? What can be achieved?

3. What have been done concerning GIC forecasts? What should be done next?

4. Other issues

Coffee will be served.
