My take on #016, using Gerald's drafts. Warped the color channels a little for better alignment and removed the slight parabolic curve from the horizon.

Thanks Mike. They are suprised Juno can detect plumes but they don’t provide the distance from the spacecraft to Io. Anyone get the information?
Thanks
SPICE Geometry calculator is your friend:

Sorry Mike, I had a lot of family in town for the holidays so I haven't been keeping up with Juno lately (besides I usually focus on JIRAM data when it hits the PDS). Congrats to your team on an amazing photo of a plume!
Now that I am back at work, I get a nice Io diversion! YAY!
Plume is from Chalybes Regio eruption, btw. Most significant post-NH eruption, has been ongoing since October 2008. I'm focusing mostly on the JIRAM image from the press release. I can say that the brightest hotspot is not Chalybes Regio, but Tvashtar, so that one is active again (it's been pretty quiescent for much of the Juno mission)
Understandable. The volcano is new since Galileo and New Horizons so the area doesn't scream "major volcano" on maps.
For scale context, our Moon would have shown 2,5 times smaller from this distance.
I better understand JunoCam capabilties now.
Here's #024, modified from Gerald's drafts. It captures the NEB from an altitude of ~5000 km.
https://flic.kr/p/2czqGnvhttps://flic.kr/p/2czqGnv
It looks like a moon shadow (likely Thebe's, if it is a shadow) is passing over the cloudtops at center right - this feature is also present in images #022 and #023 and appears to be slowly moving based on its position relative to the dark streamer beside it. Amalthea's eclipse shadow is also visible along the horizon in image #023.
Wow, you've all been rather busy, while I've been offline a few days!

Some images from my pipeline. Replaced the perspective camera render in OpenGL that I was using with the panorama camera in Blender. I'm still working on the specific camera settings that I like and will try to automate it as much as possible (I'm currently doing the Blender part manually).

Image PJ17_21 in approximately true color/contrast versions. In terms of color and field of view these are very roughly comparable to what might be obtained with a regular consumer type camera (or even a phone). However, the resolution is a bit lower.
Here's a processed version of Gerald's draft #22, which includes a candidate moon shadow along the northern edge of the NEB at about the 1 o'clock position.

If it is a shadow it shows little visible motion (if any) against the cloud tops in the 4 minutes of observation, but a map-projected version of these images is probably necessary to double check. I haven't been able to find a way to check this hypothesis other than Jupiter Viewer - Thebe is about in the right place but there's not enough information to determine if its sub-Sun point falls on Jupiter. It could just be a lookalike cyclone core (http://www.unmannedspaceflight.com/index.php?s=&showtopic=6705&view=findpost&p=183208)
There is a real moon shadow on the southern horizon though, which is undoubtedly Amalthea. Here's a cropped image to give it the limelight:
http://junocam.pictures/gerald/uploads/20190107/.
It will probably take a few more hours, until I'll have completed the according reprojections, well, unless I'll fall asleep during work after midnight.

The timelapse sequence shows some processing artifacts near the GRS, side effects of the patching algorithm for camera artifacts and energetic particle impacts.
Here the first 10 images of part 4, starting with
#28, #29,
#30, #31:
Image #40, processed from Gerald's drafts. Interesting to note that Oval BA ('Little Red Spot') is currently passing south of the GRS. Interesting to note that it shows very little coloration in this image, especially relative to previous JunoCam images where the system has a brownish core. It's especially interesting in comparison to the planning maps on the SwRI site, which appear to show a reddish Oval BA relative to the South Tropical Zone as recently as August. Definitely worth monitoring to see if a weakening trend is in progress.

Two images showing details from PJ17_21. Compared to the original data this is enlarged by a factor of 3:
The GRS animation made me shiver. Wow. I'll be watching this again and again.
The GRS animation is awesome, especially when one considers the oblique viewing angle of the original images.
But here are approximately true color/contrast and enhanced versions of image PJ17_27 ("PJ17 Equatorial Zone south"):
Composite of JNCE_2018355_17C00038_V01 & JNCE_2018355_17C00040_V01, from the perspective/location of the former.
Been getting much better results since dropping my own renderer and using Blender.

Here is an intermediate breadcrumb of one of the topics I'm currently working on, that's analysing the dynamics of Jovian weather systems on the basis of JunoCam image pairs:
Thanks! I'll consider CUDA or something similar for some portions of the upcoming tasks. GPU code might make sense in some cases, multithreading doesn't. I can easily load the CPUs of a given number of computers with 100% by just starting an arbitrary number of parallel processes, if I like. The above analysis is based on 300 runs distributed over the CPU cores available for the job.
Another composite of Perijove 17 images, this time using JNCE_2018355_17C00035_V01 & JNCE_2018355_17C00039_V01. Using the camera perspective of the former.
Lots of blending and color/contrast enhancement.

Is the great red spot really rotating noticeably in just the brief time interval of a fraction of a Perijove flyover?
I think it must be an artifact of the changing viewing angle, but Sean's GIF animation surely does give the appearance of turning a couple of degrees.
The analysis of the cloud velocity field of Oval BA in post #71 is based on two images taken within about 10 minutes. The white arrows represent the infered motion within 10 hours. The velocity field can be determined in a meaningful quantitative way from images taken within 10 real-time minutes. Sean's animation is covering a longer time interval. So, the answer is a clear yes. http://junocam.pictures/gerald/uploads/20190110/. They require some additional registering. But it's well feasible.
Here is http://junocam.pictures/gerald/uploads/20181202/extras/PJ15_polS_forthback_darkests_41_54_40ms_with_stops160ms.gif.

If a pole-to-pole pass takes about 90 minutes, it will be difficult to remain within camera range of any point in the low latitudes for more than 10 minutes, won't it? For polar regions there should be more time to register motion, but still the fact that you can infer so much longer-term dynamics from the available comparisons is remarkable. It testifies to the quality of both the optics and the processing. Very nice work.
Thanks! Near closest approach, it's very hard to retrieve any dynamical data. There, we get a mixture of dynamics and parallax. Thus far, I've been able to retrieve meaningful dynamical data from image pairs taken within six minutes, when the geometry between images isn't changing too much. For closest approach with 3,500 km above the cloud tops, the viewing angle is changing by 120 degrees or so within two minutes. I think, that for those images, it's easier to retrive 3D stereo data than dynamics. But usually, those images are too blurred and of low contrast to find significant displacement fields. At least, it's quite a bit harder to analyse them properly. As a rule of thumb, I'd say, that for ususal perijove passes, it's possible to retrieve more or less reliable velocity data outside +/-45 degrees latitude relative to the latitude of closest approach. Since this closest approach is shifting northward with each PJ pass, the quality of the data for an analysis of the southern hemisphere, including the latitude range of the GRS is improving. But I'm not yet quite at the very limit of processing the images. So, it might be possible to extend the analysis of the dynamics a little further towards the point of closest approach. I'll continue to try.

Near closest approach, there are some visible alignment inaccuracies between the blended scenes. I hope, that you can forgive me.
I forgive you Gerald!
