Abstract: Solar coronal bright points display complex internal structure when viewed at the high spatial resolutions provided by the instruments onboard Hinode and SoHO. We study the magnetic evolution of a newly formed bright point on the 6th of April 2007, using high-resolution SoHO/MDI magnetogram data as a basis for topological reconstruction of the 3D magnetic field in the corona. A dynamic network of magnetic connections exists both within the bright point itself and linking it with the surrounding magnetic features. When these changes in magnetic connectivity are compared with Hinode/XRT observations of X-ray loops and brightenings, we can gain new insights into how changes in the coronal magnetic field configuration lead to brightenings of magnetic structures within the bright point, with possible implications for coronal heating.
