Space weather events associated with solar flares, geoeffective coronal mass ejections and geomagnetic storms are associated with adverse effects on a range of satellite- and ground-based systems. Here we focus on consequences of space weather effects on ionospheric current systems, including in particular geomagnetic induced currents in power distribution networks, pipelines and other long conductors. Recent observations show that GICs are not confined to high latitudes, and at lower latitudes may be amplified by Sq currents and electrojets. Damage may accumulate progressively. This session attempts to understand the cause and effect of space weather on ground-based conductors due to perturbed ionospheric current systems, through data analysis and modeling. We welcome papers on relevant physical processes and in different regions that improve our ability to unravel the variability with longitude, season, magnetic activity, solar cycle. We particularly seek papers on mitigating space weather effects and ionospheric disturbances due to extreme space weather events.
