Abstract
We present the behaviour of the coronal index (CI) of solar activity over the period 1986-(May) 1996. These data are not only a good tool for studying the activity of the Sun as a star, but they also represent an invaluable source of information in our quest to understand the properties of the heliosphere as a whole. Having compared the variations of CI and of the solar 0.05–0.8 nm soft X-ray flux over the period 1986–1995 we did not find any significant correlation between the two quantities. This favours a scenario in which the sources of the soft X-ray flux are small-scale regions of the corona, and processes of both ionization and recombination do not occur in the same volume of the solar corona as for the green corona.
Paper presented at the SOLERS22 International Workshop, held at the National Solar Observatory, Sacramento Peak, Sunspot, New Mexico, U.S.A., June 17–21, 1996.
