The long-term steady motion of Saturn's Hexagon and the stability of its enclosed jet-stream under seasonal changes

A. Sánchez-Lavega, T. del Río-Gaztelurrutia, R. Hueso +15

We investigate the long-term motion of Saturn's North-Pole Hexagon and the structure of its associated eastward jet, using Cassini ISS and ground-based images from 2008 to 2014. We…
