Here is our report on the images from PJ72 on 2025 May 7. The imaging was fully successful. Highlights were:
--A distant view of Io showed that the fallout from the recent volcanic eruption near the south pole is still present, apparently unchanged since PJ70.
--One of the northern circumpolar cyclones, which has always been a typical ‘filled’ cyclone, has changed its form to become an almost featureless circular cloud disk – only the second major transition of a filled cyclone during the mission.
--The inbound images gave good views of the reviving N. Temperate Belt, and of a ‘reddish blob’ that has been tracked on its south edge, here revealed as an anticyclone.
--Long haze bands with curious changes in contrast can still be seen around the south pole.
Here is a PDF of the report with minitaure figures. The full-size figures will come in the next Comment. As usual, this is also posted on our BAA Jupiter Section web site. --John Rogers.
