The Pioneer Saturn vector helium magnetometer has detected a bow shock and magnetopause at Saturn and has provided an accurate characterization of the planetary field. The equatorial surface field is 0.20 gauss, a factor of 3 to 5 times smaller than anticipated on the basis of attempted scalings from Earth and Jupiter. The tilt angle between the magnetic dipole axis and Saturn's rotation axis is < 1�, a surprisingly small value. Spherical harmonic analysis of the measurements shows that the… 
Saturn's magnetosphere and its interaction with the solar wind
Pioneer 11 vector helium magnetometer observations of Saturn's planetary magnetic field, magnetosphere, magnetopause, and bow shock are presented. Models based on spherical harmonic analyses of
The magnetosphere of Saturn
Pioneer 11 and Voyager 1 and 2 magnetic field measurements over the entire flyby of Saturn's magnetic field have been analyzed by fitting a magnetospheric dipole field (i.e., a dipole field plus the
The magnetic field of Saturn: Further studies of the Pioneer 11 observations
Analysis of magnetic field observations by the Goddard Space Flight Center high-field flux gate magnetometer on the Pioneer 11 spacecraft during Saturn encounter yields estimates of the planetary
Saturnian magnetospheric dynamics: Elucidation of a camshaft model
[1] Periodic modulation of magnetospheric phenomena at Earth and Jupiter results principally from the tilt of the dipole axis relative to the rotation axis. Saturn's nearly aligned dipole moment is
Saturn's Magnetosphere, Rings, and Inner Satellites
Our 31 August to 5 September 1979 observations together with those of the other Pioneer 11 investigators provide the first credible discovery of the magnetosphere of Saturn and many detailed
Charged particle motions in the distended magnetospheres of Jupiter and Saturn
Charged particle motion in the guiding center approximation is analyzed for models of the Jovian and Saturnian magnetospheric magnetic fields based on Voyager magnetometer observations. Field lines
The magnetosphere of Saturn
The Pioneer 11, Voyagers 1 and 2 encounters with Saturn provided a wealth of information about its complex magnetosphere. The magnetic dipole moment of Saturn is rotationally aligned and only
Magnetic field structure of Saturn's dayside magnetosphere and its mapping to the ionosphere: Results from ring current modeling
[1] Ring current modeling in Saturn's magnetosphere using Pioneer-11, Voyager, and Cassini data has shown that the size and strength of the current system grows with the extension of the
Sources of rotational signals in Saturn's magnetosphere
[1] Saturn's internal magnetic field is exceptionally symmetric about its rotation axis. Yet local and remotely sensed observations of field and plasma in Saturn's magnetosphere display periodicities


Preliminary Results on the Plasma Environment of Saturn from the Pioneer 11 Plasma Analyzer Experiment
The Ames Research Center Pioneer 11 plasma analyzer experiment provided measurements of the solar wind interaction with Saturn and the character of the plasma environment within Saturn's
Compression of Jupiter's magnetosphere by the solar wind
A study of the major changes in the solar wind during the Pioneer 10 and 11 encounters and their influence on the size of the Jovian magnetosphere is reported. Simultaneous sets of encounter data
Measuring the magnetic fields of jupiter and the outer solar system
The vector helium magnetometer, one of the Pioneer-Jupiter experiments, has measured the magnetic field of Jupiter and the interplanetary magnetic field in the outer solar system. The comprehensive
Saturn radio emission near 1 MHz
Radio emissions from the direction of Saturn are analyzed which were observed by IMP-6 at 15 frequencies between 375 and 2200 kHz from April 1971 to October 1972. The radio bursts are identified in
Re-evaluating Bode's law of planetary magnetism
THE popularity of the so-called magnetic Bode's law for the magnetic dipole moments of the planets1–4 persists despite the lack of any physical justification for such a law. The magnetic Bode's law
Jupiter's magnetic tail
Magnetic field observations of the jovian magnetosphere suggest an extended magnetic tail, which has been formed by solar wind interaction with the planetary field.
