AB: Although there has been intense theoretical work in the past decade on coronal mass ejections/eruptive flares, the mechanism for their initiation is far from accepted. The problem is that the triggering of these events is believed to be magnetically-driven and to take place in the corona, but until very recently, the field there has not been observed directly. We discuss how the new developments in coronal field instrumentation will allow us to determine the mechanism for CME/eruptive flare initiation. We focus, in particular, on the so-called breakout model in which reconnection in the corona is postulated to be the triggering process. First, we present the latest numerical results on breakout. Then, we determine the predictions of the model for coronal magnetic observations, and discuss definitive tests of breakout that will be possible with the proposed new instrumental capabilities.
