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.

我们分析了日本月球轨道赛烯观察到的血浆，磁场和高频波数据，以研究月球地壳场与太阳风之间的相互作用。 首先，我们通过地壳磁场制作了质子反射/挠度的全局图。 在强层磁场上方100 km处的磁增强比取决于行星际磁场（IMF）和地壳场的方向。 至于太阳能质子进入尾流，我们发现2型质子进入了各种IMF方向。 这表明质子在时代的反射可能控制着月球夜区域。
