Present version of 4K map with both daytime and nighttime regions from the post #90 Juno images. These were additionally processed and added to a prior map.
EDIT: The nighttime region is using just the brightness information blended with the color from the prior map. This suggests the strategy of taking only green channel images at the next flyby can work pretty well. -------------------- Steve [ my home page and planetary maps page ]

That answers my question - imaging at closest approach was not feasible, it was over the night side. Phil The SRU image was on the night side, but it hasn't been released yet I think. The Ganymede and Europa SRU images were released pretty quickly after the flyby, but maybe it didn't work at Io this time? |

Family Portrait: Ganymede, Io, Europa, Callisto, and Jupiter. The right three moons and Jupiter are from PJ57-21, however Ganymede was just out of frame to the left. Ganymede last appeared in PJ57-12, so I grabbed it from that and composited it into the approximate location as it would have appeared. The moons have been brightened for visibility.
On a side note, that GRS is looking pretty small... Jupiter & Galilean Moons - PJ57-21/12 |

Can you do a plot where the SRU image is one rotation later for PJ57? The one you have plotted would be too far west and right on the terminator for Jupiter-shine. I would think that the SRU image is either the rotation after that one or two rotations, though I personally really hope that it is one rotation to get all of Tonatiuh.

Here is the plot as requested. One with your PJ57 map overlaid. I haven't thought about where jupitershine ends when selecting the frame. It was a tossup which frame to select in the first place, so the new map shows all possibilities. The footprints as shape files: io_JNO_SRU.zip ( 2.88K ) Number of downloads: 105 Any chance of PJ58 map update? |

Seeing the pictures of Io from Voyager, Galileo and now Juno, the colour of the surface seems to differ, the Voyager ones seem to picture Io as being very orange, Galileo less orangy and Juno pinkish ? Which colour is the most accurate?

PDS release for PJs 57 and 58 was officially yesterday. Pretty much everything is available now except for SRU oddly. Not sure if there was an issue with the instrument or issue with the release. EDIT: the PDS Imaging site has this to say: "SRU data is temporarily delayed" So it looks like they will be released just not yet.
But yeah, the data for all the other instruments is now available. I've been working with the JIRAM data for a few days now and it is going pretty well. They got quite a few postage stamps across the surface and they are of pretty good quality. Instrument: Juno/JIRAM Lat/Lon: 43 N/355.7 W JIRAM Time: 12/30/2023 08:37:19 JNC Time: 12/30/2023 08:37:45 Resolution: 597 m/pixel Comparison between Voyager ISS and JIRAM. JIRAM data inverted in brightness to make it easier to compare the two data sets. Lots of islands are consistent between the two. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Of ALL things, it was the instrument I needed to be released!
