行星际磁场扫过它前面的等离子体，迅速穿透到最初的抗磁性钡等离子体云中。流场在流动方向上受到强烈的压缩和伸展。被电极化场加速的离子在星云的尾部形成了一条可见的尾巴；它们的反冲平衡了磁应力。人造彗星头部的主要横向运动归因于行星际电场提取的离子的反冲。
Sweeping the plasma before it, the interplanetary magnetic field quickly penetrated into an initially diamagnetic barium plasma cloud. The field was strongly compressed and extended in the flow direction. Ions accelerated by electric polarization fields formed a visible tail at the rear of the cloud; their recoil balancing the magnetic stresses. The dominant lateral motion of the head of the artificial comet is attributed to a recoil of ions extracted by the interplanetary electric field.
