| ABSTRACT
The innermost of the Gallilean
satellites, Io continually spews sulfur into the Jovian
magnetosphere. This sulfur becomes quickly ionized and is picked up by
Jupiter's rotating magnetic field. The resulting polarization of the
plasma cloud sends currents carried by Alfven waves to the Jovian
ionosphere. Filamentary Alfven waves accelerate electrons to keV
energies causing the aurora.
This talk will present a brief review of Jovian auroral observations
and then present results of numerical simulations of auroral
acceleration in the Jovian magnetosphere. It turns out that much of
the acceleration is upward producing s separate auroral spot in the
conjugate hemisphere.
