Research Abstract

We analyzed the plasma, magnetic field, and high-frequency wave data observed by a Japanese lunar orbiter SELENE to study interaction between lunar crustal fields and the solar wind. First we made a global map of proton reflection/deflection by the crustal magnetic fields. Magnetic enhancement ratio at 100 km altitude above strong crustal fields depends on the directions of interplanetary magnetic field (IMF) and the crustal field. As for the solar wind proton entry into the wake, we found that type-2 proton entry takes place for the various IMF directions. This suggests that proton reflection on the dayside might govern the lunar night side region.
