Fig.1From: Sub-ion-gyro scale magnetic field compressions generated by the solar wind interaction with the moonA short-period magnetic enhancement detected by Kaguya at 100Â km above the moon. a The magnitude, b the azimuthal angle, and c the latitude angle of the magnetic field observed by Kaguya (black curves) in the Selenocentric Solar Ecliptic (SSE) coordinate system compared with that of the upstream solar wind observed by ACE (gray curve) in the Geocentric Solar Ecliptic (GSE) system shifted by a travel time of 1.06Â h from ACE to Kaguya. d The position of Kaguya in SSE coordinates. e The magnetic connection between Kaguya and the dayside (red) or nightside (blue) lunar surface estimated from linear extrapolation of the magnetic fieldBack to article page
