Yes they have. It is believed to be the result of a collision of 2
asteroids.

Also, isn't there a limit on how far the sound would travel before the
inverse square law would render it inaudible? 5 miles?

Several months ago I read an article which gave migration times of
material from a given orbit to the earth. Can anyone point me towards an
answer, or provide the answer. I specifically am interested in how soon
the material from this collision could find its way to Earth... tens of

I was recently selling at a gem and mineral show here in Minnesota. I
have developed a reputation among the local dealers as a meteorite

Has anyone heard an estimate for the size of the impactor yet.
If I recall correctly, for an object reaching Earth's surface with
cosmic velocity, the rule of thumb is that the crater diameter is 50
times the impactors diameter. I am guessing that factor for Jupiter's
cloud layer is going to b
It could also be the remnant of where a troilite nodule was.

rather not grind it off and re-etch the slice if I can avoid it.

My understanding is that the geology of that area is karst (i.e.
limestone) , which forms in rectangular blocks. The transfer of the
energy of the explosion was enhanced in some direction and not in
others... resulting in the squarish shape.

That was my thought at first, but the ground resolution is approx. 150
meters per pixel, so I wouldn't think so... way too big for the

Ron,
Just curious. What's that small black dot in the upper right corner that
slowly drifts off the picture to the right over several shots?
