This review, offered for the first time in Russian scientific literature, is devoted to various aspects of problem space weather impact on ground-based technological systems. Particular attention paid hazards operation power transmission lines, railway automation, and pipelines caused by geomagnetically induced currents (GIC) during geomagnetic disturbances. The review provides information main...

Abstract Space weather has long been known to approximately follow the solar cycle, with geomagnetic storms occurring more frequently at maximum than minimum. There is much debate, however, about whether most hazardous events same pattern. Extreme – by definition occur infrequently, and thus establishing their occurrence behaviour difficult even very space-weather records. Here we use 150-year ...
