Coupling of earth's magnetosphere, solar wind and lunar plasma environment

The Moon does not have significant atmosphere and magnetic field. So it was considered like a passive absorber of incoming plasma. The latest observation revealed that the significant deflected proton fluxes exist over magnetic anomalies at lunar surface. Such deflection implies that the magnetic anomalies may act as magnetosphere-like obstacles (mini-magnetospheres), modifying the upstream plasma. The present paper is aimed to describe one possible deflection mechanism and its relations to solar wind conditions. It was obtained that for considered conditions the suggested mechanism gives too low density of deflected protons. However for the big anomaly it can give amount of deflected protons in accordance with the observations. (C) 2013 COSPAR. Published by Elsevier Ltd. All rights reserved.
