Juno, perijove 10, December 16, 2017 Options

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 still images of the (somewhat preliminary) PJ-10 flyby movie are online (the site of 2017-12-22 is updated).

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 a way, what I did was 'intentionally inaccurate'. I simply increased Jupiter's radii by 200 km when reprojecting the framelets to simple cylindrical projection and also when rendering the images. By doing this I don't lose the fuzzy/hazy limb visible in the original framelets. This requires very accurate pointing information and a very accurate value for the interframe delay, otherwise you 'lose' the blue sky at the southern and/or northern limb or you get incorrect color at the limb.

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.





These images do not include a bluish/fuzzy/hazy limb because I started working on them before I started my (successful) experiments involving the limb.

The round, bluish feature with the dark centre in frame #24 reminds me of the SL-9 impact scars back in 1994.

In his recent, first PJ-10 report, 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:

(I think, that I should upload this to missionjuno.)

Here is my take on Gerald's PJ10_034...

[Gerald]

Jupiter in Perijove-10's Io shine, noisy proof of principle:

The bright object at the right is Io with stray light, Jupiter is coming in from the left.
Lots of hot pixels and energetic particle hits aren't filtered out in this version.

That is something I never anticipated could be done

[Gsnorgathon]

Good job, Gerald! Are those Jupiter's rings at the top in the last frame?

[mcaplinger]

Are those Jupiter's rings at the top in the last frame?

Those are stray light artifacts. In fact, not to be a buzzkill, but all of it could be stray light artifacts.

[Explorer1]

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...

[mcaplinger]

I can't remember. the rings have already been caught with Junocam, correct?

Yes, barely. https://www.missionjuno.swri.edu/junocam/processing?id=368

It's not the perijoves that are going into shadow, it's the approach side of the planet roughly 180 degrees from perijove. At any rate I don't think the geometry is very favorable for seeing the rings, else they might have been visible in the PJ10 images.

Junocam was never intended to look for things that were very dark.

[Brian Swift]

I can't remember. the rings have already been caught with Junocam, correct?

My take on the rings from PJ3. Includes a few more framelets, so Orion is also visible.

Here is a GIF time-lapse from the PJ10_33 and PJ10_36 images:



The images were obtained about 12 minutes apart. The time-lapse reveals the cyclonic motion of the STB Ghost which is the big feature at and slightly below center.

North is up and the images are in simple cylindrical projection.

Jupiter in Perijove-10's Io shine, noisy proof of principle:

This is an amazing image even though it's not exactly the prettiest image of Jupiter I've seen.
