  • Abstract Following the first discovery of reflected solar wind protons from the lunar surface by KAGUYA experimental team, I study the motion of the solar wind protons which are reflected from the lunar dayside hemisphere by using single particle trajectory calculations in a Monte-Carlo simulation. The global distribution of these reflected protons at 100 km altitude above the lunar surface shows strong asymmetry in north-south and dawn-dusk directions because of their large gyroradii and the directions of the accelerating electric field and the interplanetary magnetic field. The reflected protons could be accelerated to high speed in near-surface region because of the self-pickup process. Under certain condition of the interplanetary magnetic field, a portion of them can reach the shadow region which is usually considered to be devoid of solar wind protons.
