The Juno spacecraft, in extended mission, explores the environments of the Galilean satellites as it passes through Jupiter’s equator plane prior to periJove. Two close passages of Io with a minimum altitude of ~1500 km were targeted to occur on orbits 57 and 58, providing a wealth of information on Io’s interior (gravity), geologic processes, atmosphere, and interaction with Jupiter’s magnetosphere. Juno’s magnetometer investigation samples the vector magnetic field in Io’s vicinity at 64 samples/s. Here we discuss Io’s interaction with the Jovian magnetosphere and the detection of ion cyclotron waves at ~0.5 Hz, ~1 Hz, and ~2 Hz, associated with Io-genic SO2, S, and O.
