We present a detailed topological analysis of active region(AR) 10978, based on a Potential Field Source Surface (PFSS) model.AR 10978 is a standard bipolar region which appears fully covered by themagnetic field lines of a coronal streamer. Despite this simple magneticconfiguration, our analysis shows that it is possible for the AR plasma,contained in the outflows observed at the AR borders, to be released intothe solar wind via magnetic reconnection.
