Here is our report on JunoCam’s images of Jupiter at PJ58. As usual, the inbound images provided a whole-planet map, with high resolution on part of the NEB and further north, then there were hi-res views of the north polar polygon. The NEB views showed details of a faded (ochre) barge and one of the recently-appeared anticyclonic dark spots (amateur images are provided for context). The north polar map is here compared with those from the previous 5 perijoves to contrast the stability of the 8 circumpolar cyclones with the more variable histories of a smaller extra cyclone and of three anticyclonic white ovals that we are tracking in and adjacent to the octagon. An animation shows the rotation of some of the cyclones and counter-rotation in their centres.
The report, including mini-figures, is attached as a PDF. A ZIP file of the full-size figures will be posted in the next Comment.
Here is a report on the PJ58 closeup images of Io. The camera operated perfectly, and the resulting images greatly improve our maps of Io; they show three volcanic plumes on the limb; and they show specular reflections from several calderas. The report with small copies of the images is attached here as a PDF. The full-size figures will be attached as a ZIP file in the next Comment. --John Rogers

This is JunoCam's global map of Io, from PJ55, PJ57 & PJ58 (Figure 3 of the report, corrected version).
Here are the full-size figures for the PJ58 report on Io.
Correction: On Figure 3, the PJ57 map should be attributed to J.P. [Jason Perry], not Bj.J. The attribution is correct in the caption.
