[PPS08-02] Global mapping of the lunar magnetic anomalies by electron reflection method
Keywords:Moon, Magnetic anomaly, Kaguya, Electron reflection method
Apollo revealed hundreds of localized crustal magnetic fields. Lunar Prospector made a global map of the crustal magnetic fields for the first time. Kaguya observed the more detailed global crustal magnetic fields with higher time resolution and higher spatial resolution than the previous observations.
We have analyzed the reflected electron data and magnetic field data around the satellite obtained by low energy charged particle analyzers (MAP-PACE) and magnetometer (MAP-LMAG) on Kaguya. Using the electron reflection method, we will report the global map of the lunar surface magnetic fields with high spatial resolution (~8 km). Some of the observations of the reflected electron distributions showed energy-dependent loss cone by the effects of electrical potential differences between the lunar surface and Kaguya. We corrected the influence of the electrical potential difference on our result. By comparing our result of electron reflection method with the magnetic field measured by the magnetometer, we will discuss the behavior of the electron reflection over the lunar surface.
