Dark impact mark in Jupiters south polar region was created by bird
This sort of thing doesn't happen very often. The last one I remember was the Shoemaker-Levy impacts in 1994.

I sent your email on to the planetary expert's in the UK to have a look. It's looking very likely to be an impact Just waiting on other images to come in later tonight for conformation.

Anyone available should image this area TONIGHT. Assuming a System II longitude of 200degrees which is close enough, this would mean athe next transit time would be 2:33am BST. So if you're prepared to give it a go you're images could be extremely important. Especially if this is a transient phenomenon and dissapates quickly.

It sure does look like one of those impact scars from before.
I must have a look at this tonight,
I'll try to get an image also if the weather holds.

wow, thats amazing, it sure does remind me of the impacts that comet shoemaker-levy made all those years ago..
One thing I noticed is Anthony's image has a very sharp edge. Remember the SL9 scars had an arc surrounding them like a black eye. This might suggest an impact from something harder like an asteroid (which punches deeper) rather than a comet. Still speculation of course.

Frank,
that is now out of date:) The transit time for tomorrow morning is 03:01BST, So imaging 1.5 hours either side of that should show it up.

my money is still on the impactor

Mine too. One would expect a weather even to appear over a longer period of time. There is no hint of this spot in very recent images. Whatever caused it happened very dramatically. So fingers crossed!

Well 'spotted' Anthony!at 3am all I could imagine was an impactor
It'd want to be some insane weather to cause that
but anything is possible.

Looks more and more like an impact from a fragmented body, one large impact site and several small sites in a line.

ok,
multiple markings!
(I can't seem to open that newer image Anthony)
I took this shot of the area tonight 2.37am and was
surprised at just how easy it was to see it.
Io is just on the limb here also with it's shadow being cast.
10'' SCT & Philips SPC900 webcam.
Unfortunately I could not load the new key for KCCCD tools
as there is no current update so I could only capture in 15 FPS
which is a pain as the seeing was excellent tonight.
Thanks for the heads up Bird and well done
on discovering it.
