PJ24 happened back on 12/26 but the spacecraft was in solar conjunction until around the end of the year and we are just starting to get the data back. With the holidays it may be next week before images start showing up on missionjuno, so stay tuned.

The first three images from the somewhat but not very close flyby of Ganymede (it's about 78 pixels across) are up now.

Drafts of the four PJ24 Ganymede images
and slightly post-processed crops thereof: We are looking towards Ganymede's northern hemisphere. Hershef and the nearby chain of bright crater ejecta (60 to 70°E, 40 to 60°N) are well-discernible, amongst other known features. Geologic map on Wikipedia. |

No plume that I can see at Chalybes (two Io swaths down)
EDIT: now including the two images of Io from PJ24. Only very broadscale bright spots are visible (Surt "Regio", the bright area near 60/330, and Ra "Regio") -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

This is a heavily processed north polar projection map generated from image PJ24_17. In particular it has been processed to reveal features that are faintly illuminated by Jovian skylight on the nightside near the terminator. Processing images like this is now easier for me than it used to be thanks to a new empirical model of Jovian skylight near the terminator that is used when removing the effects of the varying illumination (I'm still tweaking the parameters though, therefore some post processing was necessary in Photoshop). This processing reveals what seems to be a part of the north polar cyclone very close to the north pole. Several circumpolar cyclones are also visible.
