On the relation between the CMEs and the solar flares

Abstract

The aim of this paper is to study the relation between the coronal mass ejections, CMEs, and their associated solar flares. During the period from 1996 to 2010 there are 12,433 CMEs recorded by SOHO and 22,688 flare events observed by GOES. Under certain temporal and spatial conditions, we selected 776 CME–Flare associated events. We found that there is a good relation between the solar flare fluxes and their associated CME energies, where R = 65%. In addition we found that 67% of the CME–Flare associated events ejected from the solar surface after the occurrence of the associated flare. Furthermore we found that the CME–Flare relation improved during the period of high solar activity. Finally, we have distributed the selected events depending on their flare class.
