Information on the web
The meeting is intended to be a starting point for a Nordic GIC network,
industry and research can exchange experiences, knowledge, and data.
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.
As shown in the agenda below, there will be some presentations. Our
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.
hope is, however, that there will be substantial input from some, or
all, of the participants in the form of experiences, views, and ideas.
(Space Weather refers to solar conditions that influence earth's atmosphere,
technological systems and human health. )
Kindly observe that the start of the start of the meeting has been
changed to 09.30 (from 09.00).
