Mapping Magnetospheric Equatorial Regions at Saturn from Cassini Prime Mission Observations
Saturn’s rich magnetospheric environment is unique in the solar system, with a large number of active magnetospheric processes and phenomena. Observations of this environment from the Cassini spacecraft has enabled the study of a magnetospheric system which strongly interacts with other components of the saturnian system: the planet, its rings, C.S. Arridge ( ) · G.H. Jones Mullard Space Scienc...
متن کاملMagnetospheric period magnetic field oscillations at Saturn: Equatorial phase “jitter” produced by superposition of southern and northern period oscillations
[1] We investigate magnetic field oscillations near the planetary rotation period in Saturn’s magnetosphere observed during the initial near‐equatorial phase of the Cassini mission. Phase determinations on 28 periapsis passes during this ∼2 year interval display pronounced nonrandom “jitter” relative to the ∼10.8 h modulations in the dominant southern Saturn kilometric radiation (SKR) emissions...
متن کاملThe Cassini Magnetic Field Investigation
The dual technique magnetometer system onboard the Cassini orbiter is described. This instrument consists of vector helium and fluxgate magnetometers with the capability to operate the helium device in a scalar mode. This special mode is used near the planet in order to determine with very high accuracy the interior field of the planet. The orbital mission will lead to a detailed understanding ...
متن کاملSolar Wind Parameters for Magnetospheric Magnetic Field Modeling
Magnetospheric magnetic field models are crucial for many space weather applications. However, the latest empirical models require solar wind and IMF data, which are not always available. Data gaps are especially common for times before the launch of the WIND spacecraft at the end of 1994, but even after then there are data gaps. We present a method to interpolate the solar wind characteristics...
متن کاملA Dynamic Model of Mercury's Magnetospheric Magnetic Field
Mercury's solar wind and interplanetary magnetic field environment is highly dynamic, and variations in these external conditions directly control the current systems and magnetic fields inside the planetary magnetosphere. We update our previous static model of Mercury's magnetic field by incorporating variations in the magnetospheric current systems, parameterized as functions of Mercury's hel...
