There are another three days left over to vote for Perijove-07 points of interest (POI).

This time, all eyes will be on the Great Red Spot (GRS). Provided everything works as scheduled, one RGB image will be made almost above the center of the GRS. I'd think, that this RGB image will be complemented by a methane image. Since this time, we won't have contact with Earth during the flyby, the amount of data to be collected is rather constraint. Therefore, only a small number of images of the polar region is scheduled, just enough for a long-term observation. Storage will be sufficient for imaging several POIs to be voted for, but we may not get a full latitudinal coverage.
In order to obtain a full latitudinal coverage of the GRS and adjacent regions, we should take at least one image near the northern and one image near the southern edge of the GRS, better a set of five RGB images. We would see the GRS from different angles, and we would be able to study the turbulence north and south of the GRS. I'd also expect, that only images from north and south of the GRS will be able to cover most of its longitudinal extent.
In addition, a sequence of images near the GRS would provide the raw material for a great and unprecedented fly-over movie.

That said, there are several other interesting or potentially interesting targets to consider. Besides for an adjacent region of the GRS, I voted for the two polar-most POIs, since I hope, that we'll get some additional polar and subpolar images for a long-term study, and more close-ups of those incredibly turbulent FFR zones near the poles.

Here the result of some recreation with PJ07, #053:
Attached Image

It shows Jupiters NN-LRS-1, NN for north-north, LRS for "Little Red Spot". This version is reprojected to about one and a half minutes after the original image time, in order to bring the storm closer to nadir. Then, I've enhanced the image with a sequence of several methods, first an automated heuristics which adjusts for some of the illumination and light scattering effects followed by gamma stretch to the 4th power of radiometric values, then some arbitrary white-balancing, non-linear brightness-stretch, some saturation enhancement, sharpening, point-noise filtering, masking to a disc.
