What is it about?
This paper analyzes the relationships between the main ionospheric parameter foF2 (corresponds to the maximum electron density in the ionosphere) and various indices of solar activity for middle and low latitudes in order to find the best solar activity index for studying long-term changes in the ionosphere.

Why is it important?
The result of this publication is that at least for middle latitudes, the optimum solar activity index for long-term ionospheric analyses is F30, not F10.7 or sunspots used predominantly until recently - change of paradigm. This paper initiated similar studies by other authors with the same result.
Perspectives
This paper appers to initiate change in representation of solar activity impact on the ionosphere, which could partly modify various previous results.
