Abstract

The Cassini Imaging Science Subsystem (ISS) began observing Saturn in early February 2004. From analysis of cloud motions through October 2004, we report vertical wind shear in Saturn's equatorial jet and a maximum wind speed of ~375 meters per second, a value that differs from both Hubble Space Telescope and Voyager values. We also report a particularly acitve narrow southern mid-latitude region in which dark oval are observed both to merge with each other and to arise from the eruptions of large, bright storms. Bright storm eruptions are correlated with Saturn's electrostatic discharges, which are thought to originate from lightning.
