PJ53 report

Here is our report on the PJ53 images, in the usual style.  The coverage of Jupiter was similar to PJ52, and there were no major changes.  The highlight was Juno's closest flyby of Io so far.

The report is presented as a PDF file, with small copies of the figures.  The full-size figures will be added as a ZIP file ina subsequent Comment.
