AB: We present data from the MENA instrument onboard the IMAGE satellite taken during a period of enhanced convection on 26 June 2001. During the interval, MENA observes energetic neutral atoms (ENAs) in the magnetotail and an Earthwards-propagating enhancement in their flux, at the same time as the convection strength increases (as measured by the Kp and MBI indices). Data from the magnetospheric plasma analyser (MPA) instrument onboard satellites in geosynchronous orbit indicate that enhanced ion and electron fluxes at plasma sheet energies (~1-45 keV) are detected at the same time as enhanced ENA flux are observed at the satellite location. We interpret the results as a convection-driven delivery of plasma sheet material, the ENA signature of which we observe with IMAGE/MENA. We use the rate of the propagation of the ENA enhancement to infer the speed of the plasma sheet delivery to the inner magnetosphere.
