214:
Space Weather at Ground Level I Posters


Session ID#: 44953

Session Description:
The effects of Space Weather on ground systems were most dramatically demonstrated in the Hydro-Qubec blackout of March 1989, whose causes are not yet completely understood. Recent high-sensitivity, high-time-resolution data from magnetic arrays show that large magnetic impulses can be associated with substorm-like activity, or with sudden impulses in the solar wind. In both cases, a large Z (vertically down) magnetic perturbation can occur, and by Faraday’s Law this component is very effective in inducing unwanted currents in large ground technological infrastructure such as electric grids and pipelines. Papers are invited focusing on observations, causes, effects, and mitigation of geomagnetically induced currents, and other space weather phenomena affecting ground technological systems.
