No, we didn't think that would be workable within all of the other constraints. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

That was way faster than I expected, wow QUOTE (Brian Swift @ Sep 29 2022, 09:32 PM) There was enough Jupiter-shine to bring the signal from night side up a little bit over noise levels. This brings a tear of joy to my eye, amazing work, Brian! The PSF on that reminded me of the good ol'e days of Cassini which is high praise for JunoCam. Superb work by all involved, it was a long time coming and it was executed flawlessly as far as I can I gather. -------------------- www.flickr.com/photos/ugordan

One more of PJ45_01 with some brightness and saturation boost.

Maybe with the HORUS software being used now with LROC images of shaded areas. https://agupubs.onlinelibrary.wiley.com/doi...29/2022GL099530 Phil -------------------- ... because the Solar System ain't gonna map itself.

It's going to be really hard to find anything like because the existing Voyager/Galileo coverage is mostly at much different sun angles. I'm sure people will be looking hard in the weeks to come, though. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

Very interesting and odd features. They're visible on the Galileo mosaic. Congratulations to the Juno team! John
