AB: CLUSTER observations of traveling compression regions in the near-Earth magnetotail are presented. These intensifications of the lobe magnetic field propagate along magnetic field lines at several hundred's of km/s. They are thought to be caused by the motion of magnetic flux ropes in the plasma sheet. Using the tetrahedral geometry of the CLUSTER spacecraft, we present the detailed properties of waves and particule distribution functions observed within these localized regions. The analysis of high-time resolution wave and particle data shows the complexity of wave-particle interactions taking place in these transient compression regions.
