Fig. 9
High-resolution images from the IR1 camera (top and bottom rows) in the 09d filter and two UVI images taken through the 365-nm filter (c and d, middle row). Only contrast filtered images are shown to emphasize the details. The UVI images are taken about 12 min apart and are shown as rectilinear maps to show the rapid changes that can take place in the appearance of the wavy features. In the 0.9-µm images a, e wavy and curved patterns are also seen; however, the slightly higher-resolution images b, f do not show such details. It is not known whether this is due to the transient nature of the patterns or due to spatial-scale dependence of contrasts
