Abstract:It has been proposed to use the cumulative indices, applicable when macroeconomic processes are analyzed, to study long-term trends in different heliogeophysical factor, which vary under the action of cyclic changes in solar activity. It has been indicated that trends of the UV intensity in the Lyman-α line (reconstructed based on the ionospheric data) are almost absent for the period 1957–2004.
