A magnetic superstorm occurred in October/November 1903, close to the minimum of solar cycle 14, and is well documented by variograms from Coimbra magnetic observatory (COI). During this storm, the alternative index Dst’ attained an extreme value -513 nT (Hayakawa et al., 2020). If such a storm occurred today, how large could be the currents induced along the grounded conductors of the Portuguese power system network?
