The Millenium Campaign at Jupiter combines the Cassini flyby of Jupiter, the continued orbital coverage of the Jupiter system by Galileo, and the unprecedented coverage of the Jovian aurora with the Hubble Space Telescope and Chandra to provide valuable new data on the solar wind interaction with Jupiter's magnetosphere. Several new results have emerged. Solar wind data from Cassini (Cassini Plasma Spectrometer and Magnetometer investigations) indicates two classes of auroral events that appear to be correlated with brightenings and changes in auroral morphology as observed by the Cassini Ultraviolet Imaging System and the Hubble Space Telescope. The first class is global brightenings of 20-30% associated with the passage of a shock wave in the solar wind. The second class is dawn storms and their possible association with solar wind sector boundary crossings. In addition, Chandra has observed a 40-minute oscillation period in auroral x-rays that are correlated with Cassini radio observations and field and particles observations aboard Galileo. These new observations provide unique insight into the Jovian magnetospheric system that will be discussed in this talk.
