在早晨极光椭圆的两次火箭飞行中观察到沉淀离子爆发的能量与时间的分散。单个爆发持续约20秒，并以100秒的时间尺度重复。分散体被解释为能量依赖的飞行时间延迟，其提供离子荷质比以及注入源距离的识别。这些数据是一致的磁鞘离子注入距离范围从7到19地球半径。个别事件延伸到至少几度磁经度和0.3度不变纬度的区域。有人建议，这些事件与湍流等离子体进入磁层入口层。
Energy versus time dispersion of precipitating ion bursts was observed during two rocket flights in the morning auroral oval. Individual bursts lasted about 20 seconds and repeated on a time scale of 100 seconds. The dispersion is interpreted as energy-dependent time-of-flight delay which provides identification of ion charge-to-mass ratio as well as injection source distance. The data are consistent with injections of magnetosheath ions with injection distances ranging from 7 to 19 earth radii. Individual events extended over a region of at least several degrees of magnetic longitude and 0.3 degrees of invariant latitude. It is suggested that these events are associated with turbulent plasma entry into the magnetospheric entry layer.
