The collision of comet P/Shoemaker-Levy 9 with Jupiter has caused a dramatic increase in Jupiter's microwave emission, which provides an excellent opportunity to study the physical processes to which the energetic electrons in the planet's inner magnetosphere are subjected. The PIs will (1) reduce and analyze the data obtained before, during and after the week of cometary impacts, and (2) continue their monitor program of the planet's radio emission. They will investigate the radial diffusion of the energetic electrons, determine the diffusion coefficient and relate this to the turbulence in Jupiter's upper atmosphere via the diffusion mechanism. In addition, they will determine the enhancement in the amount of dust in Jupiter's magnetosphere due to the passage of comet SL9. Finally, the PI will collaborate to explain the increase in the radio emissions.***

彗星P/Shoemaker-Levy 9与木星的碰撞导致木星的微波辐射急剧增加，这为研究木星内部磁层高能电子所受的物理过程提供了一个极好的机会。PIS将(1)减少和分析在彗星撞击之前、期间和之后获得的数据，以及(2)继续监测地球的无线电辐射。他们将研究高能电子的径向扩散，确定扩散系数，并通过扩散机制将其与木星上层大气中的湍流联系起来。此外，他们还将确定由于SL9彗星的通过，木星磁层中尘埃量的增加。最后，PI将合作解释无线电辐射增加的原因。*
