摘要

The goal of this paper is to understand the drivers, configurations, and scenarios of two similar eruptive events,which occurred in the same solar active region 9973 on 2002 June 1 and 2. The June 2 event was previously studiedby Sui, Holman, and Dennis (2006, ApJ, 646, 605; 2008, Adv. Space Res., 41, 976), who concluded that it waschallenging for popular flare models. Using multi-spectral data, we analyzed a combination of the two events. Eachof the events exhibited an evolving cusp-like feature. We have revealed that these apparent "cusps" were most likelymimicked by twisted magnetic flux ropes, but unlikely to be related to the inverted Y-like magnetic configuration inthe standard flare model. The ropes originated inside a funnel-like magnetic domain whose base was bounded by anEUV ring structure, and the top was associated with a coronal null point. The ropes appear to be the major driversfor the events, but their rise was not triggered by reconnection in the coronal null point. We propose a scenario anda three-dimensional scheme for these events in which the filament eruptions and flares were caused by interactionof the ropes.
