The sequence is part of an observation campaign to study the southern circumpolar cyclones, including their long and short-term dynamics.

The images are reprojected according to a preliminary geometrical camera model, cleaned from most repetitive camera artifacts and from most energetic particle hits, approximately illumination adjusted with a 5th degree polynomial BRDF over the cosines of the incidence and emission angle on the basis of PJ20 images, and stretched with gamma=4 with respect to radiometric values.

Resolution is 30 pixels per degrees in an equidistant cylindrical system centered to the camera at image stop time, with an axis parallel to Juno's spin axis. The rendered field of view is 60x180 degrees.
