英文摘要Outflowing ion beams forming four successive inverted-V structures in the energy-time spectrograms of H+, He+, and O+ were observed at an altitude of 3.4 R-E by Cluster satellites travelling above the auroral acceleration region (AAR) in the southern hemisphere on February 14, 2001. Energization by negative U-shaped potential structures in the AAR is believed to be responsible for the formation of these outflowing ion inverted-V structures. Thus, utilizing the different motion properties of the three ion species, the altitude of the upper boundary of the AAR is estimated to be similar to 11100 km. Moreover, based on multi-satellite observations, each ofthese U-shaped potential structures involved in this event crosses the latitud in aldirection at similar to 0.4A degrees-1A degrees invariant latitude (ILAT), moving poleward at an average speed of similar to 0.2A degrees ILAT per minute, before disappearing at similar to 71.5A degrees ILAT.
