How many "Jupiter Years" has that storm been going on for? At least 100? It's orbit is what? ~35 earth years?

Jupiter's period of orbiting the Sun is almost 12 years. The current spot has only been reliably observed since about 1830. Older 17th century observations may have been a similar but different spot in a different belt.

Geez - where'd I get 35 from??!!?? :?

That's an incredible amount of time - I cannot imagine the power it must take to, well, power that storm. Of course, to ME it's an incredible amount of time.

To the planet, and the solar system, and the galaxy, and the universe - well..... :Think:

Yes, BUT, the truly weird thing that makes the GRS seem weird is that unlike a terrestrial tropical cyclone where the eyewall strengthens and moves in the GRS is an ANTIcyclonic storm, a HIGH pressure system. :lol: Opposite pressure difference but the same behavior.
