Abstract
Spacecraft observations of the interplanetary magnetic field at 1 AU (astronomical unit) are shown to have frequency spectra with a dependence in the range 2.7 × to 8.0 × Hz. We suggest that the spectrum results from the superposition of uncorrelated samples of solar surface turbulence that have log-normal distributions of correlation lengths corresponding to a scale-invariant distribution of correlation times over an appropriate range of parameters.
