Cassini ISS images from 4 March 2008 (left panel), and 18 June 2008 (right panel). The left image shows mainly one bright storm cloud, whereas there are two bright storms in the right image. In the 4 March image the bright storm F¹ is located at 302° western longitude. We have marked the features A, B, and C corresponding to the features shown in the right panel of Fig. 5, that were imaged by M. Suarez two days later. This shows that spot S³ is actually a large dark oval. The 18 June image shows two bright spots at 310.3° (F²) and at 343.4° (F¹) western longitude, with the older storm cell F¹ further west (left) than the younger storm cell F². All spots are located around ~35° south planetocentric latitude. The left image (file name W00043078.jpg) was taken with filters CB3 and CL2, and the right image (file name W00046585.jpg) was taken with filters CB3 and IRP0 (Images by NASA/JPL/SSI).
