Spatial & Temporal Characteristics of Ha flares during the period 1975-2002 (comparison with SXR flares)

TL;DR

This paper analyzes the spatial and temporal patterns of solar H-alpha flares from 1975 to 2002, comparing them with soft X-ray flares to understand their evolution during the solar cycle using self-organized criticality theory.

Contribution

It provides a statistical interpretation of solar flare characteristics over multiple solar cycles, linking their behavior to self-organized criticality theory.

Findings

Flares exhibit intermittent stochastic behavior correlated with the solar cycle

Spatial and temporal patterns of flares follow self-organized criticality models

Comparison with SXR flares reveals similarities in their evolution patterns

Abstract

Although the energetic phenomena of the Sun (flares, coronal mass injections etc.) exhibit intermittent stochastic behavior in their rate of occurrence, they are well correlated to the variations of the solar cycle. In this work we study the spatial and temporal characteristics of transient solar activity in an attempt to statistically interpret the evolution of these phenomena through the solar cycle, in terms of the self-organized criticality theory.
