The PJ20 images showing areas near the equator are especially interesting.

Below is an enhanced map-projected image processed from PJ20_34 showing the area from planetographic latitude 5 degrees south to 6.6 degrees north. The image has been processed to better reveal various subtle features and color variations. The enhancement/processing parameters differ for different parts of the image. The enhancement is strongest in areas that have low contrast in the original imaging data.



Various interesting cloud features can be seen; perhaps the strangest one is the 'fleet of ships' (a term first used by John Rogers in his PJ20 report) in the lower right quadrant of the image. Interestingly the 'ships' are oriented at an angle of roughly 30-60 degrees relative to faint north-south oriented striations in this area. The visual impression I get from the image is that the 'ships' are higher in the atmosphere but this could easily be wrong. Similar features are visible in a few Voyager 1 images obtained shortly before closest approach but the new JunoCam images are much better.

A number of additional interesting features are also visible in this image; many of them look very subtle in a true color/contrast version of this image (see below).
