It's time to start a new topic for Juno's Perijove-09.
Due to solar conjunction, data downlink is delayed several days, but things appear to look good thus far.
Data downlink started on October 31, and if everything continues well, it should be a matter of a few days, at most, until the majority of the raw Perijove-09 images will become available. Due to the incremented available storage for JunoCam, we may get a sufficient coverage to render a pole to pole -- well, almost pole to pole -- fly-over reconstruction, despite the difficult communication near solar conjunction. I'll have a try at least, over the next few weeks.

The PJ9 images are on missionjuno (although the front page doesn't say this yet.)

PJ-09, quick & dirty version without SPICE nor shape model, therefore close-up portions not yet properly RGB aligned.
The enhanced versions will take another few hours.

This is the 10-fold reduced testrun of the version I'm currently rendering:

Gerald, thanks for making the quick and dirty versions available so quickly. I have processed image #105, which is a family portrait of Jupiter with Io and Europa.


Perijove 9 Departure - JunoCam

A small amount of unsharp masking was applied to enhance some of the detail, which reveals what look like real albedo features on Io's surface. This image is simply enlarged by 3x:


Ganymede Perijove 9 detail - JunoCam

This is Io's southern hemisphere but I'm not entirely sure which features should be visible. Maybe Tarsus Regio?

Great to see you finding out which moons those are, while I've been rendering and uploading the enhanced versions of the close-ups to the missionjuno site. smile.gif

Here the JPG version, going to be distributed over several posts:

As usual since Juno has been orbiting Jupiter, the close-ups start with images of the north polar region.

PJ-09, #80, and #81, with close-ups of the northern "folded filamentary regions" (FFRs), mostly cyclonic turbulent storms known for their increased probability to show lightnings:

Image #105 shows some artifacts near the GRS induced by my patching algorithm for camera artifacts. The algorithm uses nearby colors to fill in invalidated regions, which works pretty well in most cases, but not near the GRS.
