Abstract: | In the period of the International Geophysical Year (IGY), almost the entire planet was covered for the first time by ground-based
geophysical observations. Their analysis led to two fundamental results: the existence of the auroral oval and auroral (magnetospheric)
substorm. At the final stage of the IGY, satellite explorations of the near-Earth space began. The auroral luminosity appeared
to be related to the plasma structure of the magnetosphere. That opened new possibilities for parameters diagnostics of the
Earth’s magnetosphere on the basis of ground-based aurora observations. The concepts of auroral oval and magnetospheric substorm
became paradigms of the new science of solar-terrestrial physics. |
