The Cassini Fly-by of Jupiter: Correlation of Cassini and Galileo Magnetometer Data

During October 2000 through March 2001 the Cassini spacecraft was within 0.5 AU of Jupiter. Using a data set which combines the Cassini magnetometer data with that of the Galileo spacecraft in orbit around Jupiter we provide a perspective on solar- planetary interactions at Jupiter using dual site measurements. In particular we show the coherence over large scales of much solar wind field structure and show the re- sponse near Jupiter to upstream changes.
