Flares and Plasma Flow Caused by Interacting Loops

Remote brightenings, defined as small brightenings distant from the main flare sites during flares, have been observed by many authors. The coronal configuration underlying the phenomenon is understood to be multiple loops (Nakajima et al., 1985; Machado et al., 1988; and Benz, 1993). However, there remain important questions. Is the remote brightening only a by-product of a single loop flare? Does an interaction between loops in the multiple loop structure causes a flare?
