Abstract
Quasi-periodical variations in the magnetic fields of long-living, small-scale magnetic structures, solar facular formations (FFs), are analyzed. We used the method of Empirical Mode Decomposition (EMD) to reveal the empirical modes of time series of magnetic field variations in four FFs and tested them for the existence of coloured noise. We proposed a qualitative interpretation of statistically reliable oscillatory modes.
