A time series of soft X-ray emission observed by the GOES satellites from 1974-2007 is analyzed. We show that in the periods of high solar activity the energy distribution of soft X-ray solar flares for M and C classes is well described by a FARIMA model with Pareto noise. The model incorporates two effects detected in our empirical studies. One of them is a long-term dependence (long-term memory), and another corresponds to heavy-tailed distributions. Finally, we address a challenging problem of how to build a proper physical model for analyzing fractional dynamics (Langevin or Fokker–Planck) with long-range dependence of empirical data sets.
