Abstract
Coronal transients are believed to involve the expulsion of magnetic ‘bubbles’ or loops into interplanetary space. The close relationship of coronal transients with other forms of solar activity suggests a variation in their frequency of occurrence by a factor of 3–10 over the solar cycle. As magnetic ‘inclusions’ in the interplanetary magnetic field, transients should then lead to a solar cycle dependent scattering of cosmic rays entering the inner solar system. The power spectrum of a model of the transverse magnetic fluctuations and its solar cycle dependence is compared to the observed power spectra. Coronal transients are tentatively identified as the solar origin of the low‐frequency power in the interplanetary field and, as such, an important factor in cosmic ray modulation.
