AB: The Magnetospheric Imaging Instrument (MIMI) Ion and Neutral Camera (INCA) on the Cassini spacecraft has recorded abrupt increases in energetic neutral atom flux coming from the general direction of Saturn's magnetotail. These bursts of ion activity in the tail seem to be related to solar wind magnetic field direction as well as the passage of compression regions, and are well correlated with enhancements in the Saturn kilometric radiation. Given the similarities between these events and substorm activity on Earth, including their dependence on interplanetary conditions, we conclude that Earth-like substorms occur within Saturn's magnetosphere. Unlike Earth, the hot plasma is quickly convected about Saturn at close to corotation speed.
