BHP universality and gaussianity in sunspot numbers fluctuations

TL;DR

This paper analyzes sunspot number fluctuations and finds that their distribution is a mixture of the BHP distribution and Gaussian distribution, revealing a complex underlying statistical behavior.

Contribution

It introduces the novel finding that sunspot number fluctuations follow a mixed distribution of BHP and Gaussian, expanding understanding of solar activity statistics.

Findings

Sunspot fluctuations follow a mixed BHP and Gaussian distribution.

The distribution mixture indicates complex underlying dynamics.

Results contribute to solar activity modeling and prediction.

Abstract

We analyze the famous Wolf's sunspot numbers. We discovered that the distribution of the sunspot number fluctuations is a mixture of the BHP distribution with the Gaussian distribution.
