在与哈雷彗星相遇期间，织女星1号航天器上的磁力仪(Mischa)观测到上游弓形波导致的磁场湍流水平增加。织女星两艘航天器都测量到峰值磁场强度为70-80 nT，并观察到彗星障碍物周围的磁力线覆盖。观测到了磁场矢量的意外旋转，这可能反映了磁力线穿透到与太阳风和彗星等离子体的接触面相关的扩散层中，或者反映了先前存在的行星际磁场结构的持久性。
During the encounter with comet Halley, the magnetometer (MISCHA) aboard the Vega 1 spacecraft observed an increased level of magnetic field turbulence, resulting from an upstream bow wave. Both Vega spacecraft measured a peak field strength of 70–80 nT and observed draping of magnetic field lines around the cometary obstacle. An unexpected rotation of the magnetic field vector was observed, which may reflect either penetration of magnetic field lines into a diffuse layer related to the contact surface separating the solar-wind and cometary plasma, or the persistence of pre-existing interplanetary field structures.
