Can only echo thanks to the Juno team and to everyone else working on and supplying this astounding imagery.

My jaw has literally been hanging open this whole thread.

I have updated the following portrait from Perijove 06







Excellent work by Bjorn & Justin!

So great to see Jupiter at this level of detail... I will endeavour to tread gently.

As I mentioned previously, these latest JunoCam images are awesome. I took a fairly detailed look at one of the images I posted earlier with particular attention to cloud elevation differences. First an unusual image. This is a perfectly flat DEM with several spikes - their shadows show the direction of sunlight in one of the JunoCam images I posted earlier:



And here is the corresponding JunoCam image. This is one of the images I posted earlier but here I have added some annotations:




A. Bright, high altitude clouds that usually seem to be isolated or to occur in small clusters.

B. These clouds are similar to (A) in color and altitude. But unlike (A) they appear elongated, probably parallel to the wind direction. At least in some cases they indicate high wind speeds - clouds like these are visible at lower resolution in Voyager images showing the northeast periphery of the Great Red Spot where the wind speed is very high.

C. I suspect that here we are seeing the darker and lower cloud deck through tenuous and mostly transparent high altitude clouds. This is more obvious when looking at the red channel only.

D and E. Here JunoCam may have directly observed/imaged the elevation difference between the dark clouds and the less dark clouds south of the 'color/brightness transition'. Areas indicated by (D) appear slightly darker than areas indicated by (E). When taking into account the direction of the shadows in the DEM/spike shadow render above, the areas indicated by (D) may be in shadow caused by the brighter clouds south of the brightness/color transitions while the areas indicated by (E) are not in shadow.

F. These clouds seem somewhat similar to (A) but they occur in far bigger clusters. Apparently they also might be at a slightly lower altitude - this is not obvious though.

G. Possible shadows hinting at elevation differences but color/brightness variations are also a possibility. Features like this are very common.

Superb image processing and analysis. Great to see both enhanced and unenhanced/realistic versions to get the complete picture. Some first reactions - if I have the larger scale context right:

The dark areas next to D/E look like the IR hot spots at the edge of a belt.

The shadow in D agrees with my subjective impression of the brighter laminar appearing clouds being higher and overlaying the darker adjacent clouds.

G looks like cloud brightness variations to me. These narrow strands look similar even in differing orientations?

"A" features clearly have high cloud tops. I wonder if their bases are low enough to tap into the water vapor layers, helping to give enough opacity to yield the brighter white color. The more true color images suggest these tops may still be below some of the high altitude haze. This haze is yet thin enough to have distinct shadows visible. It seems there's a narrow range of haze optical thickness that allows this type of visibility.

For completeness, a few hours ago I've uploaded revised #122, and #123, after fixing the overflow for saturated pixels.
The first version of the PJ06 flyby animation is completed, too. It's now mostly a matter of upload bandwidth. I'll try an upload to youtube, as well as a first subset of zipped stills to the junocam.pictures webspace, and intend to provide links in about two or three hours. The zipped stills will be 2.34 GB, more than I can upload before next week.

Going to make some interested-layman interpretations of the meteorology here.

One observation is that the two largest A-type clouds seem to be found at eddy inflection points, right where the white clouds meet the brown clouds. I wonder if these might be supercell-like convective systems that are popping up along the boundary of white and brown clouds, and whose development is aided by favorable upper level conditions created by air diverging as it rounds the inflection point of the eddy.

F-type clouds seem to be more embedded within the local flow and are vaguely oriented in "streets" parallel to the flow direction. These are kind of reminiscent of the cloud streets that tend to form in the dry slot of a mature low-pressure system, or in clusters of multicell convection in strong upper level wind regimes where the updrafts tend to form trains.

B-type clouds look like cirrus streaks formed getting blown off the tops of the more intense convective clouds, and if you look closely at the A-type cloud clusters near the center of the image, you can see some of these streaks beginning to form as elongated cloudtops on individual convective cells.


Maybe a more clear example of what Bjorn is getting at with point C can be seen just to the right of the F at left center. There is an extremely dark brown cloud rotating around the top of the eddy that has an apparently sharp edge, but if you look closely you can see that it continues underneath the lighter clouds. (Not at a computer where I can highlight this but if anyone is having issues seeing what I'm talking about I'll try to have something up within a day)

Here is a preview of the sequence Gerald shared... upscaled, rotated and put through a 12 step batch process.

I extended the length of the content x3 and I'm still deciding how to blend between jump cuts as well as tracking the full crescent to avoid linear cuts.

Scott Bolton said "around 50 km" several times during the press conference. So, about the size of a major US city's metro sprawl, and twice as big as the average thunderstorm on Earth.

From the image it is not clear to me exactly what this is - brightness variations, differences in cloud altitude or even both. What I had in mind is illustrated in more detail below. This is a section of my original image enlarged by a factor of 3:



A. Slightly darkened. Tilted away from the sun?
B. Slightly brighter than A and slightly darker than C. Elongated depression / 'trough'?
C. Slightly brightened. Tilted towards the sun?

These elongated features are parallel to each other roughly in the the NNW-SSE direction. By looking at similar features with a different orientation I'm not sure which interpretation is correct. If these features are brightness variations B should always be present whereas A and C would only be present when the orientation is not too far from N-S.

The upload of the stills of the first release of the PJ06 flyby is completed by now.
I hope, that I didn't overlook some of the stills. It should be 2401 images. for a total of 96.04 seconds with 25 fps.

The seeming relief-- maybe call it drop shadowing-- at the belt edges in Sean's post #53 is just beautiful.

Here is the full sequence of Perijove 06 based on Gerald's animation.

Upscaled to 1080, Uptimed variably x6, Processed x12

I tried to correct the linear paths the camera took & there were missing frames toward the end when compared with Gerald's original video.

Uptiming this has resulted in emphasizing the texture jump cuts which I have tried to disguise as best I could. I decided in favour of spending more time on the sharpest areas so I omitted a short area on the equatorial which warped badly when trying to find vector paths for displacing pixels. I might come back to this when I have more time.

**update**

Here is a version with Gerald's original timing & path fix...



...and a x2 retimed version...
