English: On July 5, 2022, Juno performed a "Voyager-class" encounter with Io a set of eight of Io's northern hemisphere near closest approach (two others were also acquired but were on the edge of the frame so are not included here). The images shown here are in time order with the crescent view at top left taken 33 minutes before closest approach and the gibbous view at bottom right taken 38 minutes after closest approach.

The most significant change visible even at this low resolution (original resolution was 58 kilometers or 36 miles per pixel) is around the active hotspot Chors Patera, best seen just below and to the left of center in the lower left image. The dark area appears larger than it did 20 years, when the region was last observed by Galileo. This dark region is surrounded by a bi-lobate bright area which appears more prominently than it did in Galileo data. Another interesting area of investigation is the northern portion of Lei-Kung Fluctus. This region is dark in the crescent views at top left, but as the phase angle increases, this region brightens and fades into the background. This provides information on the surface roughness of older flows compared to the surrounding terrain.

Each image have been reprojected to a point perspective map projection, centered on the sub-spacecraft point for each image. The resolution of each image varies from 14.5 kilometers (9 miles) per pixel with the image at lower right to 11.6 kilometers (7.2 miles) per pixel for the image at upper right. This matches the viewing geometry of the original JunoCAM images, but are enlarged by 5x.
