Blast my impulsive nature! wink.gif This morning I decided—against my better judgement—to tackle this seven-footprint RGB monster of a mosaic. It's still not finished, but should still give a good idea of what the final product will look like:

This new mosaic includes terrain visible to LORRI via haze-illumination only and includes putative cryovolcano Piccard Mons:

Let's not forget that Pioneer 11 got our first half-decent look at Jupiter's north pole, and it didn't spy anything hexagonal.

Nonetheless, this recent Juno image release is just a taster of the really good sauce that's yet to come cool.gif

Bjorn,

I spent a whole half-hour sitting in a darkened room last night, exploring your Jupiter imagery on my Kindle. It was a spine-tingling experience, and I have never seen the King of the Planets look so good!!

I was inspired to work on geometrically correcting the PDS calibrated imagery—utilising your custom-made flatfields—to produce the best Jupiter composites I've ever rendered. Thanks to the tiepoint info, an Excel macro, and the Unwarp plugin for ImageJ, I finally succeeded in warping the cleaned CALIB frames to match the GEOMED products.

This is the final result: a color view made from orange and violet frames shuttered by Voyager 1 on March 2nd, 1979:

Without correction for geometric distortion, the Jupiter approach movies will look as though they were filmed underwater (I speak here from bitter experience).

I've already completed this particular video using a much more refined version of the method outlined in this clip from 2010:

Here's a snippet of the final movie, which I can't yet release for various reasons: (But look out for it soon cool.gif )

It really does appear to be a cloud, visible in two separate WAC frames:

And yes, the subsequent NAC views show that the cloud candidate has vanished:

This is *right* in my wheelhouse, as I've been tinkering with various Voyager data-sets for a few years now, looking for suitable sequences to be turned into movies. To date I've worked on:

Thanks Jason! Yeah, I've been looking for a way to give the CB3 frames some color for a while now, and seemed to have hit upon a recipe that works:

This is a 'color' version using the CB3, MT1 and MT3 filters:

I think belated acknowledgement and congratulations are due for Bjorn's magnificent achievement of making it to the front cover of Sky & Telescope (or at least his Voyager GRS composite did, anyway). cool.gif

The cover of the March 2016 issue:

This movie consists of 386 wide-angle camera frames captured by Cassini on April 25, 2016. The monochrome frames were colourized using a lone Red-Green-Blue composite.

The circular feature north of Menvra is fascinating: it appears prominently in this earlier ISS view from 2010:

Also, it's rather prominent in the VIMS mosaic assembled from T-114 data:
