Juno Perijove 49, March 1, 2023 Options

[volcanopele]

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.

The PDS release of the PJ49 data was last week so here are some processed JIRAM products from that Io encounter:

M-band stack (with colorized overlay on basemap)


L-band stack (with colorized overlay on basemap)


Color merge of both L- and M-band observations (greyscale areas are M-band only) - in general yellow/white is hotter than red/orange hotspots


Experimental merge between that color product and the PJ55 basemap
