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. https://pirlwww.lpl.arizona.edu/~perry/Juno/pj49.htm -------------------- &@^^!% Jim!

These BAA reports assume that the reader is familiar with the belt/zone nomenclature. It is explained here (includes a nice diagram):
https://britastro.org/jupiter/programme.htm Lots of acronyms. The "B" at the end of an acronym means "belt" (they are dark) and "Z" means zone (they are bright/whitish). A "T" means "temperate" and "Trop" means "tropical". So e.g. SSTB is the "South South Temperate Belt". The width and color of the belts/zones varies though and sometimes the narrow ones disappear temporarily even though the zonal wind speed at the relevant latitudes doesn't change when this happens. There is also some interesting information here: https://britastro.org/jupiter/guide.htm |
