[PEM16-18] Magnetic field disturbances observed by Arase (ERG) associated with the magnetic dipolarization
Keywords:Arase, magnetic field, dipolarization
The Arase (ERG) satellite was launched on December 20, 2016, to investigate the plasma physics in the inner magnetosphere. The energy exchange between particles and fields is one of the major subjects of the Arase project. We are studying the magnetic dipolarization and associated disturbances observed by Arase. The characteristics (compressibility, polarization, propagation direction, and so on) are investigated for typical events to limit the generation mechanism of the disturbances. Very close investigation of the disturbances should lead to the future statistical study, occurrence ratio, distribution and relation with the particle signature.
