Fig. 1.

Electrons and ions over magnetic anomalies observed at ~100 km altitude. Magnetically reflected solar wind ions were observed by IMA when Kaguya flew over magnetic anomalies during the time period indicated by a blue box. (a) Position of the Moon in the GSE coordinate system. Nominal magnetopause and bow shock boundary positions are also shown. (b) Field of view configuration of MAP-PACE sensors. Magnetically reflected ions were observed at satellite positions. (1), (2), and (3) indicate the positions where Moon-facing sensors observed solar wind. (c)-(f) Omni-directional E-t spectrograms from the PACE sensors. (g) Magnetic field intensity and altitude of Kaguya. (h) Magnetic field direction in GSE polar coordinates. (i) Solar wind IMF measured by ACE shifted by 50 minutes taking into account the propagation time. (j) Solar zenith angle of Kaguya. (k) Latitudinal/longitudinal position of Kaguya in the Mean Earth/Polar Axis (ME) coordinate system and the Selenocentric Soar Ecliptic (SSE) coordinate system.
