在木星的夜面磁层中，旅行者一号和二号检测到了重新连接的信号。克里米吉斯等人认识到并指定为磁层风的反太阳流事件显然与磁场向北倾斜有关。重新连接可能是由于需要将延长的夜间磁力线的长度调整为白天磁层的尺寸，但它不是稳态特征，并且表现出相当大的变化性。除了这些事件之外，还多次出现北向和南向场极性在中性片处混合的情况。航海家 2 号观测到的后面这些事件超过了约 80 RJ，其中观察到的穿过中性片的场超过了偶极子场强度，它们可能代表了撕裂模式的产物。
In the nightside Jovian magnetosphere, Voyager 1 and 2 detected signatures of reconnection. The anti-sunward streaming events, recognized and designated as magnetospheric winds by Krimigis et al., were clearly associated with the northward inclination of the magnetic field. The reconnection is likely to be due to the need to adjust the length of the extended nightside field lines to the dimension of the dayside magnetosphere, but it is not a steady-state feature and shows considerable variability. In addition to these events, there were numerous occasions where northward and southward field polarities were mixed at the neutral sheet. These latter events were observed by Voyager 2 beyond about 80 RJ where the observed field across the neutral sheet exceeded the dipole field strength, and they probably represent the product of the tearing mode.
