AbstractWe analyze the magnetic structures in the near-tail at XGSM = -17.5 RE on September 19, 2003 by Cluster. During the course of a substorm event, the earthward propagating plasmoid and flux ropes in the near-tail are observed. The earthward propagating plasmoid is associated with the bipolar Bz and By signatures. The two flux ropes are embedded within the earthward plasma flows, which might be referred to the population as "BBF-type" flux ropes. The first flux rope diameter is about 0.7 RE and duration based upon the Bz signature is similar to 20 s, while the second one diameter is about 1.4 RE and duration is similar to 30 s. The earthward propagating plasmoid and flux ropes could have influence upon the dipolarization and injection in inner magnetosphere. The Cluster observations of earthward propagating plasmoids on flux ropes are formed repeatedly and ejected tailward in the course of geomagnetically active time.
