我们研究了日冕物质抛射（CME）的速度和相关耀斑的GOES X射线峰值通量之间的关系。注意到以前的研究可能受到投影效应和随机关联效应的影响，我们考虑了两组精心挑选的CME耀斑事件：四个同源事件和四个观测良好的肢体事件。在相应的样品中，CME速度和相关耀斑的GOES X射线峰值通量之间存在良好的相关性。当对同源事件的CME速度进行投影效应校正时，两个样品的所有八个事件都有同样好的相关性。我们的研究结果表明，CME运动学和耀斑过程之间可能存在着密切的关系。
We have examined the relationship between the speeds of coronal mass ejections (CMEs) and the GOES X-ray peak fluxes of associated flares. Noting that previous studies were possibly affected by projection effects and random association effects, we have considered two sets of carefully selected CME-flare events: four homologous events and four well-observed limb events. In the respective samples, good correlations are found between the CME speeds and the GOES X-ray peak fluxes of the associated flares. A similarly good correlation is found for all eight events of both samples when the CME speeds of the homologous events are corrected for projection effect. Our results suggest that a close relationship possibly exists between CME kinematics and flaring processes.
