A New Disturbance in Saturn's North Sub-Polar Region We ask for 3 orbits of DD to urgently observe Saturn's atmosphere due to the development of a rare large disturbance that is occurring in the sub-polar region of the planet. It has been initially observed by amateurs astronomers in mid-May and Cassini can observe it but under poor conditions of visibility due to its current and next month orbital path. This disturbance can give important clues to understand the dynamics of Saturn's tropospheric weather layer.
