Voting for Perijove 06 started yesterday, and it will last for another almost 7 days.

This time, I'm not quite free of bias, since I'm interested in an extension of the polar time-lapse sequence, especially in a coverage of the north and south polar FFRs and the presumed edge of the respective polar haze disks. I think - well, I'm rather certain - that it's possible to infer short-time dynamics of the FFRs, and of the vortices near the edge of the haze disk. Due to the expected good contact to Earth during the PJ-6 pass we have a good chance to obtain overlapping images of these regions.
More in the discussion section on the missionjuno site. Of course, there are other interesting targets, too; see Glenn's and John Rogers' (Philosophia-47) comments.
A full latitude coverage would allow for a pole-to-pole animation.

Part of the PJ6 dataset has been posted to missionjuno. There were some GDS/DSN issues that are holding up the rest of it, which should be posted on Monday.

It's the kind of images, I've hoped for, and it's beyond my expecatations. I hope we'll get similar images of the southern FFRs.

Large version (30 pixels per cylindrical camera degree) of the first part of PJ-06 images.
For these images, I fixed two known flaws in my image enhancement subroutine.

I'll upload them to the missionjuno site later today.

New wonders to behold on Jupiter. I like this section of Gerald's collection with the array of round circulations:

After NASA / SwRI / MSSS / Gerald Eichstädt

Image processing: edge filters, repairs & levels



and a sequence...level boost & sharpening, no repairs.



Can't wait to see the movie on this Gerald!

Last one... my favourite image from the latest sequence with many repairs, a blended high pass overlay and blended levels pass.

Beautiful work. Maybe someone could take a run at correcting the color manually. I can't really publicize this as is because I'll have to field too many questions about why it's so green.

That's great, Sean. It almost induces vertigo, which is high praise indeed!

Thanks but all credit to Gerald for the work he has put into producing these images.

My focus was much less on color than it was on the details in the image.

**I've updated the following with more repairs**

Here is a version without the green cast... I tried to be modest but I have a version either side which might suffice also.



...and the same correction applied to the sequence...

Seán, you deserve credit for fixing my shortcomings. My means are limited, so your help is well appreciated.
