Kaguya orbit from 04:10 to 04:30 UT on April 2, 2008. a The location of the Moon projected onto the XY plane in the GSE coordinate system, with typical locations of the Earth’s magnetopause (MP) for the dynamic pressure of 0.7 nPa (Shue et al. 1998) and the bow shock (BS) (Slavin and Holzer 1981). b–d Kaguya orbit in the SSE coordinate system. The spacecraft locations at the times when the electron pitch-angle distributions in Fig. 3 were taken are also indicated by black points (a–i)
