From: ELF magnetic fluctuations detected by Kaguya in deepest lunar wake associated with type-II protons
Dynamic spectrum of magnetic fluctuations combined with particle measurement on 29 September 2008. Top to bottom: dynamic spectrum of y component B y -sse of magnetic field in SSE frame of reference measured by MAP-LMAG magnetometer on board Kaguya, magnetic connection of Kaguya to dayside (red bars) or nightside (blue bars) surface of the moon, energy time spectra of electrons detected by ESA2 sensor (on zenith-looking panel) and ESA1 sensor (on nadir-looking panel) of MAP-PACE, energy time spectra of ions detected by IEA sensor (on zenith-looking panel) and IMA sensor (on nadir-looking panel), magnitude and directions of magnetic field measured by LMAG, solar zenith angle, and longitude of Kaguya. Wave activity was observed at 0:08 to 0:12, accompanied by type-II protons, when spacecraft was magnetically disconnected from lunar surface. Horizontal lines at 2, 4, and 8 Hz in the top panel are artificial noise.
