Resumen
LAROCCA, Patricia A. y SILBERGLEIT, Virginia M.. Períodos perturbados: disipación de energía y corrientes geomagnéticas inducidas. Geoacta [online]. 2010, vol.35, n.1, pp.17-24. ISSN 1852-7744.
In a typical event (12-13 June 2005), solar wind energy rate and total energy dissipation rate in the magnetosphere (e and Ut respectively) and increased induced currents in a gas pipe located in the auroral zone are studied. For the period geomagnetic indices AE and Dst, and the Bz component of the interplanetary geomagnetic field are analyzed as indicators of the development of the troubled period. Ring current decay times are calculated using different approaches in accordance with the phases of the storm. During this period there were significant geomagnetic variations due to geomagnetic substorms and induced currents on the pipeline located in the Otawa River Valley, this fact could produce corrosion increases in its structure.
