Using the solar flare time series from January 1, 2006 to July 21, 2016,<br />we develop a complex network for predicting solar flares. In the work, hybrid model<br />is employed to construct complex network. In addition to the position of the flares<br />and their occurrence times, the energy of events based on the Telesca-lovallo model<br />is also used to develop solar flare network. Using constructed complex network, the<br />Omori’s law for fore flare and after flares associated with a main flare are retrieved. The<br />frequency of occurrence of solar flares decreases over time as a power law. Statistical<br />analysis of flaring events catalogues indicates that a power-law dependence characterizes<br />the occurrence of both fore flares and after flares corresponding to a main flare. The<br />hybrid model reconstructs the Omori’s law for fore flare–after flare process associated<br />with a main event. https://ijaa.du.ac.ir/article_180_ff54f8b8df9ccefc5c4ef0fb519cd8ee.pdf
