This topic will consist of discussion of Juno operations post-JOI until end of mission, currently anticipated in Feb 2018.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The success of JunoCam outreach depends largely on "the public" providing creative image products. So yes, it's of course welcome to create derived products of my images.
Here an early attempt to enhance Jupiter and its satellites (together with some hot pixels) with one non-monotonic stretching function: -------- I see a strong hint, that the ratio between Juno's rotation period and JunoCam's interframe delay changed at some point of the Jupiter approach. To get to this conclusion, I've looked at swathes which got Jupiter into the field of view near start and stop time of the swath. Here an image early in the approach phase (image 200), processed by assuming 80.943 exposures per rotation: It looks well-registered. Here image 1330, late in the approach phase, with the same assumption: It looks slightly misaligned. By changing the assumption to 80.956 exposures per rotation, the result looks good: The change would correspond to either a change of Juno's rotation period of about 5 ms, or equivalently to a change of JunoCam's interframe delay of about 60 μs.
