From: ELF magnetic fluctuations detected by Kaguya in deepest lunar wake associated with type-II protons

Figure 1

Example of magnetic field variation in the ELF range in the deepest wake. Found by MAP-LMAG magnetometer on board Kaguya on 24 September 2008. Top to bottom: (a) dynamic spectrum of y component B y−sat of magnetic field in the spacecraft frame of reference, (b) magnetic connection of Kaguya to dayside (red bars) or nightside (blue bars) surface of moon, (c, d) energy time spectra of electrons detected by ESA2 sensor (on zenith-looking panel) and ESA1 sensor (on nadir-looking panel), (e, f) energy time spectra of ions detected by IEA sensor (on zenith-looking panel) and IMA sensor (on nadir-looking panel), (g, h) magnitude and directions of magnetic field measured by LMAG, (i) solar zenith angle of Kaguya, and (j) longitude and the latitude of Kaguya in SSE and ME coordinate systems. The B y−sat component was chosen because it was less contaminated by artificial noise than the other two components.
