The planet Mercury has a weak, global magnetic field that was explored in detail by the MESSENGER spacecraft. In the region of space in the planet's shadow, 420 km above the surface, MESSENGER observed several occasions where the magnetic field was enhanced relative to the planet's intrinsic dipole field. This is called dipolarization. In this study, we explain the times and places where these observations occurred and present information about the distribution of plasma and waves in the magnetic field associated with these dipolarization regions. We present two conceptual frameworks for the electric current systems that could give rise to these observations.
