The magnetic field signature obtained by Cassini during its first close encounter with Titan on 26 October 2004 is presented and explained in terms of an advanced model. Titan was inside the saturnian magnetosphere. A magnetic field minimum before closest approach marked Cassini's entry into the magnetic ionopause layer. Cassini then left the northern and entered the southern magnetic tail lobe. The magnetic field before and after the encounter was approximately constant for approximately 20 Titan radii, but the field orientation changed exactly at the location of Titan's orbit. No evidence of an internal magnetic field at Titan was detected.
介绍了卡西尼号在2004年10月26日首次近距离飞越土卫六期间获得的磁场特征，并根据一个先进模型进行了解释。当时土卫六处于土星磁层内部。最接近之前的磁场最小值标志着卡西尼号进入磁层顶离子层。卡西尼号随后离开北部，进入南部磁尾瓣。飞越前后的磁场在大约20个土卫六半径范围内大致恒定，但磁场方向恰好在土卫六轨道位置发生了变化。未检测到土卫六存在内部磁场的证据。
