Jupiter's magnetic field and its interaction with the magnetized solar wind were observed with the Pioneer 10 vector helium magnetometer. The magnetic dipole is directed opposite to that of the earth with a moment of 4.0 gauss R_J^3 (R_J, Jupiter radius), and an inclination of 15° lying in a system III meridian of 230°. The dipole is offset about 0.1 R_J north of the equatorial plane and about 0.2 R_J toward longitude 170°. There is severe stretching of the planetary field parallel to the equator throughout the outer magnetosphere, accompanied by a systematic departure from meridian planes. The field configuration implies substantial plasma effects inside the magnetosphere, such as thermal pressure, centrifugal forces, and differential rotation. As at the earth, the outer boundary is thin, nor diffuse, and there is a detached bow shock.

We express our gratitude to the following persons for their dedication and support in preparation for, and during, the Pioneer encounter: A. M. A. Frandsen, B. T. Tsurutani, J. Mannan, E. Parker, B. V. Connor, G. T. Foster, and J. Van Amersfoort. The Pioneer project performed an outstanding job of processing the encounter data in near real time. We benefited from close contact with G. Mead and the particle investigators, especially J. Wolfe and his collaborators in the plasma experiment. This report represents one aspect of research carried out by the Jet Propulsion Laboratory under NASA contract NAS7-100.
