ENERGY-TIME DISPERSED CHARGED-PARTICLE SIGNATURES OF DYNAMIC INJECTIONS IN JUPITERS INNER MAGNETOSPHERE

We report on the first detection of energy-time dispersed charged part icle signatures of dynamic injections within Jupiter's inner magnetosp here. They were observed by the Energetic Particle Detector on the Gal ileo spacecraft. The signatures documented here were detect-ed most cl early in similar to 15-880 keV electrons when Galileo was near local n oon at a radial position of similar to 11 R-J. On the basis of the cha racter of the signatures (similar to 60-min signatures within each ene rgy channel and up to similar to 90-min time dispersions between chann els), the injection disturbances occurred 24-33 h prior to the time of the detections and spanned similar to 2.5 h (<40 degrees) of azimuth at the time of the disturbances. Possible generation mechanisms and si milarities with Earth magnetosphere events are discussed.
