Keywords:Field aligned electron flow, lunar wake, vortex, polarization, Kaguya

Field aligned electron flow was found by Kaguya MAP-PACE instrument in association with vortex at the lunar wake boundary inferred from the polarization of the magnetic field fluctuation observed by MAP-LMAG with respect to the background magnetic field. The speed of the electron flow was 4000 km/s and the direction was consistent with the equivalent electric charge generated by the magnetic field convected by the vortex motion at the wake boundary.
