Juno perijove 28, July 25, 2020 Options

[Bjorn Jonsson]

The images from perijove 28 are now available. This is image PJ28_24 in approximately true color/contrast and enhanced versions:






Image 28_24 was obtained shortly before Juno's perijove which makes it a very high resolution image. The resolution is highest (slightly better than 3 km/pixel) in the top center area in the 'central' image (the biggest image). At this high resolution some of the cloud features look rather fuzzy.

Not a lot of detail there - can we be sure these aren't cosmic ray hits, eg?

Maybe I should provide links to the maps the gif is derived from.
Here the RGB maps.
And here for a closer inspection selected green images for lightning search.

Specifically, #87, and #90.
There are only very few energetic particle hits in those images. And the lightning candidates are located at FFRs, where lightnings would be plausible or expected.
So, besides the structure of the spots, the location hints towards lightning on a probabilistic basis.

In the lower third of this site, you'll find less processed drafts to look for possible energetic particle hits and for stars to compare them with lightning candidates.
