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.

Jupiter - PJ18-20



Jupiter from the North - PJ18-20/26

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



Image time: 2019-02-12T14:15:02.370. Distance: 278,217 km

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

Thank you Kevin for pointing out on Twitter that JunoCAM got a look at Io on this pass.

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.


Io with Chalybes Plume - PJ18-6

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.

Processed versions of #029 and #031 using Gerald's draft pipeline.


Polar Jet N6 and Cyclone - Perijove 18


Brown Barge - Perijove 18

[ectoterrestrial]

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.

[jccwrt]

"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.
