对IMP-8尾瓣磁场测量结果进行了检查，以确定ISEE-3在遥远地尾探测到的旅行压缩区（TCR）现象（据信是由向尾移动的等离子体引起的）是否存在于更靠近地球的地方。这项研究在X ={负}31到{负}37 R{下标E}的距离上产生了16个tcr的例子。在详细考虑的两个事件中，观察到tcr与叶中的亚风暴生长相特征密切相关。这些tcr的长度估计为8 ~ 12 R{sub E}。他们的结论是，IMP-8 TCR观测提供了新的证据，证明在X = {-}35 R{sub E}方向有时可以存在小等离子体，从而存在多个重联中性线。
An examination of IMP-8 tail lobe magnetic field measurements has been conducted to determine whether the traveling compressions region (TCR) phenomena detected by ISEE-3 in the distant geotail, and believed to be caused by tailward moving plasmoids, are present closer to the earth. The study produced 16 examples of TCRs at distances of X = {minus}31 to {minus}37 R{sub E}. For two events considered in detail TCRs were observed in close association with substorm growth phase signatures in the lobes. The lengths of these TCRs are estimated to be 8-12 R{sub E}. It is their conclusion that the IMP-8 TCR observations provide new evidence that small plasmoids and, hence, multiple reconnection neutral lines can sometimes exist earthward of X = {minus}35 R{sub E}.
