Omori’s Law in the Occurrence of Solar Flare : Approach of Hybrid Model

Solar flares are large-scale phenomena that have a significant effect on the Earth’s climate. Using the solar flare time series from January 1, 2006 to July 21, 2016, we develop a complex network for predicting solar flares. In the work, hybrid model is employed to construct complex network. In addition to the position of the flares and their occurrence times, the energy of events based on the Telesca-lovallo model is also used to develop solar flare network. Using constructed complex network, the Omori’s law for fore flare and after flares associated with a main flare are retrieved. The frequency of occurrence of solar flares decreases over time as a power law. Statistical analysis of flaring events catalogues indicates that a power-law dependence characterizes the occurrence of both fore flares and after flares corresponding to a main flare. The hybrid model reconstructs the Omori’s law for fore flare–after flare process associated with a main event.
