Jupiter latest images.

Hi all

Just wondering if anybody knows of a resource that has up to date and regularly updated images of Jupiter. I understand that some of the belts and zones rotate at different speeds dependant on their position on the planet.

This will mean that features move relative to each other. Where can I get up to date images of this. (does anyone know if Cartes du ciel is accurate in its rendering of Jupiters surface features over time)

Do features such as festoons/dark spots fade/appear often or are they fairly constant.

Thanks in advance

Don't know of any such software. I think the changes are too chaotic for Cartes Du Ciel or the like to predict them. They are afterall weather systems and it's not as if we can evenpredict those on the wee earth so what chance have we got on Jupiter!

I usually check for Jupiter atmospheric changes on ALPO Japan. These are daily images of Jupiter taken by amateurs around the world. There was the IOPW (International Outer Planet Watch), they appear to only show images whenever there is a spacecraft in the vicinity.

Thanks for that

Another thing to note I guess, is that (as an example) the GRS would move pretty much at the same spped across the disk in its equatorial belt of cloud. I have seen (is it) ephemerides(??) of the passing of the GRS, just like the 4 Galilean satellites.

Is it something like this you are looking for Trevor?

Programs like starrynight are good for calculating GRS sightings, but I dont think that are usefull for belt activity or anyhting else on the surface.
They use a jpeg image of the planet and rotate it as per the planets day length.
