Data of Juno's Perijove-10 are going to be downlinked.
Here is a tiny 6000-fold time-lapsed simulation from 2017-12-16T16:30:00.000 to 2017-12-16T20:00:00.000:
It shows, that during approach, Jupiter's night side has come into JunoCam's field of view, first. Then there have been some interesting new perspectives, before Jupiter's south polar region has been in JunoCam's view during departure.
The simulation is based on preliminary, and on some reconstructed SPICE data. Timing of actual image data differ from the stills of the above tiny simulation.
I can't wait for new pictures !
This is also interesting (from https://www.missionjuno.swri.edu/junocam/voting?id=8 ):
Near closest approach, the contrast turned out to be pretty low during previous flybys, resulting in DCT block artifacts of approximately the size of potentially interesting features, and a slow flyby movie would also degrade in quality due to the visibility of the compression artifacts. Additionally, near the latitudes of the GRS, there seem to have formed large turbulent features before PJ9 that are worth images of good quality. The geometry of future perijoves will worsen for flyby animation purposes. So, this may by one of the last opportunities to take an according sequence.
Regarding observations of the polar CPCs, we'll likely get better results for the south than for the north due to image geometry and illumination.
Regarding latitude: The correlation of time and latitude won't be as strict as it has been for early orbits. This is another reason, why voting for features on certain latitudes would be less applicable.
Provided, Juno gets an extension until 2021, and the instruments will still be healthy, the answer is yes, the geometry will improve again.
The Perijove 10 images are now being added to the raw gallery.
With some delay, http://junocam.pictures/gerald/uploads/20171220/. The second half of the PJ-10 close-up images are still to be downlinked.
This version is rendered without 3D information; so the close-ups are misaligned a bit. Image #002 shows two of the moons, the larger one should be Io, according to the title. Might be, that there is more, but it's what I've seen at first glance. Of course, there are lots of energetic particle hits.
This already looks like an exceptional set Gerald...and the lack of artifacts on closest approach is also very promising.
Great early processing by Kevin as well!
I can only imagine what Matt has up his sleeve...
A tiny animation of the RGB images available thus far:
And here a larger version of some of them, first #018, and #020:
Rendition of the very close-ups takes a little longer.

Here's the remainder of my 1st pass of the Perijove 10 data that's available.

Updates to PJ10 images with improved color. Alignment is still a bit rougher than I'd like.
Kevin--Like Sean you can start with Gerald's extremely carefully aligned and processed images and just work you magic from there. Gerald was working on his image pipeline way before Juno arrived in orbit and has been improving it with each orbit. But, if you want to do it all on your own, more power to you as your are making impressive images.
http://junocam.pictures/gerald/uploads/20171223/. Those aren't yet properly aligned, since they are rendered without trajectory data nor shape model.
I'm working on a version with trajectory data and shape model. This will likely take a few more hours.
And http://junocam.pictures/gerald/uploads/20171222/. This site may be updated the next few days with more fragments.
Floyd, I'm stubbornly working on my own pipeline. :-) Gerald's is far more advanced than my own, but I've been enjoying the work (and I tend to rewrite it every couple months). I do have a number of additions to it in terms of viewing geometry and Spice calculations but they weren't ready for this perijove.
-- Kevin
I really value Kevin's contributions as they provide an alternative to how I'm interpreting Gerald's images. In some cases I have reviewed what I have done as a result. I would consider his work part of my workflow now! ( Thanks Kev! )
I'll provide the second part of PJ-10 in the order the rendition is completed, starting with #44 and #45.
http://junocam.pictures/gerald/uploads/20171223a/, and submitted to missionjuno.
The images are vertically 180 degrees, and horizontally 60 degrees FOV. They are reprojected to Juno's trajectory position at image stop time.
The images are decompanded, approximately illumination-adjusted according to an illumination model inferred from PJ06 TDI-2 images, gamma-streched to the 4th power of radiometrical data, mostly patched from repetitive camera artifacts, and approximately exposure-adjusted based on the 99.9% quantile.

THANKS SO MUCH GERALD FOR YOUR STELLAR WORK IN ADVANCING THE CAUSE OF ENLIGHTENMENT FOR ALL HUMANITY!
Here's my humble take on your movie:)

Happy Holidays & New Year,

The purpose here was to test animated masks between separate shots in order to fill out the frame. There is work to be done to blend exposure differences as well as the usual processing.

Here are my versions of image PJ10_028. I recently made minor improvements to my processing. The biggest difference is that now I no longer 'lose' the fuzzy and bluish horizon at the limb in the hi-res images as as result of the processing (the limb isn't sharply defined in these images as in my earlier images). First three approximately true color/contrast versions:
Thanks, AviSolo!
The vast majority of the merits ought to go to the many people working in the background, who make all this possible!
A happy and successful year 2018 to all of you!
I'm also looking forward to the creativity of the image processing community, which will contribute to the capabilities of all of us.
Björn's blue sky is a first interesting item to add; thus far, I've obtained similar results only unintentionally, when I worked slightly inaccurately.

In the meanwhile, most of the relevant http://junocam.pictures/gerald/uploads/20171222/ are online (the site of 2017-12-22 is updated).
And here are my versions of the PJ10_024 image (North North Temperate Belt) in approximately true color/contrast and in enhanced color, contrast and sharpness. Image PJ10_024 is centered near latitude 40 degrees north; this area has been especially photogenic in the JunoCam images.
In https://britastro.org/sites/default/files/PJ10_JHR-report-Part-1.pdf, John Rogers (BAA) suggested, that these dark patches might be soot as a result of lighting activity in thunderstorms.
Here a heavily enhanced version of a still of my prelimnary PJ-10 flyby animation:
Here is my take on Gerald's PJ10_034...
https://flic.kr/p/FhohTA
Jupiter in Perijove-10's Io shine, noisy proof of principle:
That is something I never anticipated could be done
Good job, Gerald! Are those Jupiter's rings at the top in the last frame?
I can't remember. the rings have already been caught with Junocam, correct? I know there was the star tracker image back on Perijove 1 ( https://photojournal.jpl.nasa.gov/catalog/PIA21644 ). At least, they would be something for Junocam to catch now that the perjoves are gradually going into shadow...
Here is a GIF time-lapse from the PJ10_33 and PJ10_36 images:
https://www.missionjuno.swri.edu/Vault/VaultOutput?VaultID=14561&t=1519669284.
https://youtu.be/7c_CyVW9p2Q combines two time-lapse rates at the same time. The overall motion is a zoom-in of the changing perspective along Juno's trajectory over the south polar region. A fast time-lapse is looping over a set of images reprojected to a similar perspective, such that you can perceive feature motion in Jupiter's storm systems.
Towards the end of the movie, there is a rapid change between day and night side. So this might not be recommended for people with epilepsy.

Hi Volcanopele--Very interesting. Could you label the three images as I'm not sure which is from which passage. As you are doing all this new analysis, maybe a good time to update the Gish Bar Times.
Those three are all from PJ10. I made another post in the PJ9 thread for images from that pass.
I’m working on a new post for the Planetary Society where I think I’ll include these.
