Amateurs’ contributions to Saturn study during and after the Cassini era

During the Cassini mission around Saturn, amateurs’ observations were useful to follow the evolution of the features observed by Cassini with the Imaging Science Subsystem cameras. It also proved particularly useful for identifying and following the source of Saturn Electrostatic Discharges (SEDs) observed by the Radio and Plasma Wave Science (RPWS) instrument, as shown by a recent study on 2008 data. With the mission’s end, amateur observations prove even more important to measure the wind…

In 2012, after the 2010/2011 Great White Spot (GWS), amateur observations made it possible to follow the evolution of the “GWS zone” centered around 41° planetographic north latitude, in particular…
Deep winds beneath Saturn’s upper clouds from a seasonal long-lived planetary-scale storm
- Environmental Science, PhysicsNature
- 2011
Observations of a storm at northern latitudes in the peak of a weak westward jet during the beginning of northern springtime, in accord with the seasonal cycle but earlier than expected, and triggered a planetary-scale disturbance that circled Saturn but did not significantly alter the ambient zonal winds.
