标题： Multi-Wavelength View of Flare Events on November 20, 2003

摘要： 我们分析了2003年11月20日发生在 NOAA 501活动区的两个耀斑事件。H-α 和磁像仪测量显示了两条丝状结构之间的相互作用，这导致了一个缓慢上升的耀斑事件，对应于两次磁重联过程。两组黑子系统的相对顺时针旋转引起了丝状结构的失稳。第二耀斑主相位中的尖顶状磁场及其与耀斑带分离的相关演化为日冕物质抛射（CME）爆发提供了证据。通过星际等离子体散射（IPS）图像展示了日冕物质抛射相对于黄道平面的传播和方向。 显示英文摘要

摘要： We analyze two flare events which occurred in active region NOAA 501 on November 20, 2003. The H-alpha and magnetogram measurements show interaction between two filaments which produced a slowly rising flare event, corresponding to two stages of magnetic reconnection. The relative clockwise rotation between the two sunspot systems caused filament destabilization. The cusp-shaped magnetic field in the main phase of the second flare and its evolution in correlation with ribbon separation provide evidence for the cause of the CME eruption. The propagation and orientation of the CME with respect to the ecliptic plane is illustrated by IPS images.
