I'm going to choose to be optimistic about PJ49, so with that in mind, I have added previews of JunoCAM's observations of Io for PJ49. Obviously, JunoCAM's real observation plan will likely differ but I added previews for the first and last opportunities to image Io on the pass, a preview of an image nearest closest approach, and one for when Io is near the center of the JIRAM FOV. The observation at closest approach also has the Marduk plume which has a good chance of being observed on this encounter, presuming it is active. The Volund plume might also be visible near the terminator.

The previews use the Voyager/Galileo basemap. The left images were originally projected at the same resolution as JunoCAM but were then enlarged by 5x while the image on the right is the basemap reprojected to 5x the JunoCAM pixel scale.

Just adding a note that I hope to have my preview video out sometime in the next couple of days. Script is done but it is longer than normal so I'll need to sort out what footage/images goes where.

No images yet... Hopefully this just means that MSSS is performing some extra checks verification steps on the data after the issues they had the last time around, or their pipeline is choking on the Jupiter/Io combo images. Spacecraft seems to be fine as the reconstructed C-kernel showed up Wednesday around noon.

PJ49_77 Io, "Long exposure" TDI=6, Adjusted with .4 gamma to show a little Jupiter-shine on night side. Don't see any signs of plumes along limb.

My first image processed

Definitely a pain with some flat field artifact that needed to be corrected. The one in BLU_004 worked fine with my flat field image, but not so with the one in RED_002. That's why Mulungu and Susanoo look red.
