Jupiter's vortices at and near the south pole, animated from reprojected and heavily enhanced PJ03 close-ups and departure images:

800-pixel version submitted to missionjuno.

I'd presume, that this should be the first such animation of Jupiter's south polar region.

The animation shows haze features in the south polar region, too, mostly close to the terminator.

PIA21378 - http://photojournal.jpl.nasa.gov/catalog/PIA21378 - with some additional image processing from me, to realign colour channels and clean up the image artifacts.

Despite Juno's safe mode around PJ02, JunoCam was able to add some information regarding the 2016 NTB outbreak. The according paper is online now. Solar conjunction made observations from Earth difficult. So, even the small "Marble Movie" images taken several days before PJ02 have been able to add value, especially regarding the configuration of the plumes early after the outbreak.

Synopsis of Perijove-03 subset:
Attached Image


Larger subset of larger versions.

For illumniation adjustment, I've divided the decompanded colors by a polynomial of degree 5 of the cosines of the solar incidence and emission angle, resulting in a sum of 21 items. The polynomial is a manually slightly modified relative best-fit within a range of cosines of the two mentioned angles that avoids proximity to limb and terminator. The best-fit is based on a set of about one million Monte-Carlo samples taken from all TDI-2 Perijove-06 images without moon shadows. For this sequence, I've used the polyomial of the green filter for all three color bands, hence didn't apply illumination-dependent white-balancing. I modified the best fit in order to get some shading instead of a flat appearence, and in order to avoid a non-intuitive bright terminator.
The PJ-03 images have been a test, whether the same polynomial can be applied globally for any perijove and image.
The ad-hoc heuristics I've used before for PJ-06 and PJ-07 is less suitable for PJ-03 due to the proximity of the terminator for the very close-ups.

These images aren't yet submitted to missionjuno. I may submit the fully resolved version of the synopsis, but I'll wait with the individual images, until a decision is made of whether a separate section will be defined on the site, for this kind of products.

I'll try to revise PJ-04 and PJ-05 in a similar way, before raw PJ-08 images will be available via missionjuno.

Last night, I've rendered three more versions of PJ-03 reprojections with slightly varying shading:
- Almost flat,
- shading with gamma = 0.5 applied to illumination model, and
- shading with illumniation model.

The underlying illumination model is refined a bit in order to get more uniform results near the limb and terminator.

Selected images are submitted to missionjuno.

During upload, I encountered error messages that behaved a bit like conflicting hash keys in an almost full hash table. The same upload failed reproducibly, but changing file names or titles somtimes avoided the error:
QUOTE
Uh oh, we ran into some errors.
ERROR (clam2) : Sorry - something went wrong with the upload process.


I hope, that I'll be able to upload PJ-09 renditions this week. If not, I'm intending to post them here in the PJ-09 thread any case.

The upload issue appears to be fixed. Great job! Thanks to the professionals in the JunoCam team, and to RadicalMedia! smile.gif
