利用Cluster星簇sc3卫星2001年10月1日09:46-09:50UT时段磁场和等离子数据,探测到近尾尾向传播的两个磁通量绳,时间间隔为26 s.通量绳结构的尾侧存在高速地向流,地侧有高速的尾向流.同时观测到了尾向流的重联X线源区和地向流的重联出流区,直接地观测到了近尾无碰撞多重X线重联.
Observations of the Earth's magnetotail made by the Cluster II during 09 : 42 09: 50UT on October 1 2001 are presented. Two tailward magnetic flux ropes bounded by earthward and tailward convective high speed flows were observed. We directly detected the source of tailward high flow and the outflow region of earthward flow. Combining the observations, we provided important experimental evidence of multiple X lines reconnection. The time interval between two magnetic flux ropes was about 26 s.
