Thanks guys, I'm still processing data... should have one or two more good images to come.
The spot has been imaged in methane (CH4) by Damian Peach and others in the UK and looks bright at that wavelength, this is generally considered to be a sign of high altitude material, and looks promising to confirm it as an impact.
Considering the location (close to the poles where storm activity is minor and things are always quiet) it's not likely to be anything else, but it will take a while longer for any official results I guess.
cheers, Bird

"Amateurs can do real astronomy..."
Well, the Wright brothers build the first aeroplanes,
and "professionals" the Titanic.
No matter what, it's a marvelous achievement's Anthony!!
You are a inspiration, teacher, master for all of us! Thank you!
The "iceinspace" is the place to learn, teach, and trade. Period.
One way ticket to Mars. And beyond.

It'll be interesting to see how long this feature hangs around....and how it develops, if at all, over time.

I know, I have a sarcastic mind that speaks faster than my mouth.
That's got to be one massive impact. Blows my mind.
Would you say it's big as the Earth? (impact site / black plume dot)
So far, only one impact site? (no breakup of material like S-L 9)
Such Awesomeness, Anthony!
Yep, and the clouds are "IN" Melbourne yet again. Always when a show is "ON", so are the clouds.
Going to see if I can stay up late on a weeknight now and wait for the clouds to go away!

I'm so bummed I'm in Melbourne this week, otherwise I would've been out imaging last night as well - and tonight!

Yes I was thinking about you being 1000KM away from your scope at just the wrong time !

Brett, if that had hit earth we'd be in serious trouble, but on Jupiter it's relatively small. I'd hazard a guess that the impact mark I saw was about the size of the north american continent, given that the GRS is roughly earth-sized.
cheers, Bird

I'm pretty sure the GRS is 2x the size of Earth!
Making the new impact site at least the size of our Moon or bigger?

Yes, well spotted. I should have googled that. I think I remembered the short radius being about the size of the earth or something. Its a bit smaller now than it was a century ago.

Spot on Mike.
The GRS is an oval about 12,000 by 25,000 km, big enough to hold two Earths.

Of course it'll have to be known as the "Great Bird strike", excellent work bird.

You have to remember that the dynamics of an object hitting Jupiter are somewhat different than those hitting the Earth. Whereas most of the impacting energy of an object hitting the Earth is deposited into the ground, on Jupiter it has only a deep atmosphere to dissipate its energy into. The dynamic characteristics of the explosion are different. On Jupiter, you have a blast that's akin to a massive airburst. Basically, the object plunges into the atmosphere till it reaches a depth where the atmospheric resistance becomes greater than the object's structure can handle and it flash vapourises. It forms an enormous fireball which looks for the point of least resistance to escape to, which in this case is up. It's much like creating an enormous torch like jet of superheated atmospheric gases and asteroid/cometary materials that blasts its way to the upper atmosphere and then spreads out. In a planet which is predominantly gas, the effects are very spectacular, even for relatively small to medium impactors. However, the object which caused this was probably quite substantial in size.....Chicxulub in size, maybe. If it was, then it was a 100 million megaton explosion, and we know how big a hole it excavated!!!.
Huge, but far less spectacular than a similar burst on Jupiter.

Glenn Orton from JPL is imaging the site now with the NASA Infrared Telescope and he;s just told me it's an impact . So I guess that's official :-)

Mate ! I am so happy for you.
Thrilled to bit's
Somewhere there must be an image of the object before the strike. There will be a lot of image checking going on.
