Geometrical projections of discontinuity events during 2022. This supporting figure displays the same examples of discontinuity as in Figure 1, but as equirectanguar (cylindrical) projections with an angular resolution of 0.75° per pixel. The images are projected for latitudes 90°N–90°S (vertical axis) and local hour coordinates (horizontal axis). The discontinuity was apparent on the nightside lower clouds with 2.26 μm images from IRTF/SpeX taken on February 4, and on the dayside middle clouds as observed with images by amateur observers taken with filters covering wavelengths 700–900 nm during May 5, 15, 25, 30; June 14, 19, 24; and July 13, 18, 23, 28. Exceptionally, the discontinuity seemed to manifest at the top of the dayside clouds with Akatsuki/UVI images at 365 nm during June 14. The red rectangles represent the areas where we expect to find the discontinuity when considering June 14 as the reference position and mean rotation period of 5.11 ± 0.09 terrestrial days.
