Extended Data Figure 2

The unannotated version is shown in Fig. 2. The composite components from each perijove pass that were used to create the figure are noted. Each corresponds to the polar image taken at a time that minimized the emission angle over most of the pole, as detailed in Extended Data Table 2. The PJ4 component is identical to its contribution in Fig. 1, with contributions from the other perijove passes, separated by approximately 90° in longitude, as noted. The northern cyclones forming the inner square (actually a rhombus) of the ditetragonal pattern are labelled by odd numbers and those forming the outer square by even numbers. The southern cyclones forming a quasi-pentagonal shape are numbered sequentially, with the largest spacing between cyclones labelled 1 and 5, indicated by the ‘gap’ label. Despite the time differences of 53 to 106 terrestrial days between JIRAM images acquired on PJ4, shown broadly in Fig. 1b and d, and JunoCam images in PJ1, PJ3 and PJ5, the positions of the cyclones are remarkably consistent in System III longitude.
