Quick conversion to 3D with new pipeline and rendered with Blender Cycles with "camera" positioned at middle frame
producing equirectangular 16-bit PNG at 45.51 pix/deg.

Thank you Kevin for pointing out on Twitter that JunoCAM got a look at Io on this pass. Here is my quick take:

The Chalybes Regio plume is still visible along the terminator. here is a simulated view from Cosmographia:

Thanks for telling me that the Chalybes Regio plume was there! To be safe, I tend to assume that type of pixel-sized anomaly are artifacts of my processing pipeline. I went and processed it from the raw to bring out the plume. Quick process and applied heavy sharpening.

Here is a link to PJ18 drafts, part 1.
Here according reprojections of the rgb images, almost illumination adjusted, and stretched with gamma=4.
Versions with gamma=1, and just decompanded and square-root encoded (gamma = 0.5).

I'll upload five JPG images of the gamma=5.

There seems to be a new bright hot pixel, distinctly visible in #20 of this version with my previous hot pixel mask.

Nice. Is that "The Brown Barge" or A brown barge. I'm a bit new to this nomenclature.

Great example of cyclonic updraft, then high altitude shear. The Solar System's biggest anvil cloud. Don't tell the tornado chasers, somebody will get hurt.

"Barge" is the observer's term for any elongated dark cloud. "The" brown barge was a similar feature in the North Equatorial Belt. Given recent trends in Jupiter's weather patterns, there is a good chance we see several develop this year.

Here is a link to those drafts.
And here a link to an almost illumination-adjusted version, with subsequent gamma stretch.

I'll upload the according JPGs, with the portion exceeding 180 degrees cropped.
