In the standard flare/CME model, converging magnetic field lines in the corona reconnect to release vast amounts of energy. This liberated energy is used in heating plasma, accelerating particles, and driving coronal mass ejections (CMEs). This work presents tentative observational evidence of converging magnetic field lines before the initiation of a CME using the SECCHI suite of instruments onboard STEREO. During a limb event on 25 January 2007, one 'leg' of the CME is observed to propagate "inwards" at a rate of 1.5 km/s for 4 hours before reconnection occurs. As the CME begins to accelerate, a (thermal) coronal X-ray source is observed by RHESSI in the 6-12 keV energy band. The downward motion of this source is temporally correlated with the acceleration phase of the CME, and is therefore interpreted as the collapsing X-point associated with the reconnection.
