Abstract

The sunspot number (SSN), the total solar irradiance (TSI), a TSI reconstruction, and the solar flare index (SFI) are analyzed for long-range persistence. The SSN, TSI, and TSI reconstruction are almost certainly long-range persistent with most probable Hurst exponent H ≈ 0. 7. The SFI process, however, is either very weakly persistent (H < 0. 6) or completely uncorrelated.
