Hi Pete:
As at least one other person has said, please be careful with the
definition of bolide. The IAU does not recognize the term (they do not
recognize terrestrial or gas giant or Jovian for planets either, but that
is a part of another story). However, if you look at the Wikipedia
List,
I've added a few more pieces, including a framed piece (though the
photograph of it is not so good at the moment). Working on getting more
excess material out there soon...

topic: grading system for orientation
just trying to get things started off here.
i don't believe there should be 10-grades of orientation, as was
suggested, as it seems too broad and results in a situation that is
similar to the one before us: the too-liberal invocation of the
term.
Bob List,
In light of this now-interesting debate and discussion re: orientation, I
went ahead and posted another image of the anterior face with its
perimeter-encircling rollover lip:

quick stab
as a result of a lack of tumbling and corkscrewing through the
atmosphere (the result of the object's mass, distribution of mass and
angle of entry), the object maintains a somewhat stable horizontal
and vertical axis during its plunge through the atmosphere,
Dear List Members,
Starting a little later today, I have 94 meteorite auctions ending, most of
which started at just 99 cents and others with starting points with great
values. There is everything from Super-Rare Achondrites, Falls, NWA's and
even a few unclassified stones, along with
for those working on the subject the literature below may be of use. 1,2 and 4
cover certain aspects of the subject, 3 and 5 offer an approach to the matter
istself. I am sure there are other valuable sources.

Great suggestions, Darryl. I would go even a little less complicated and
suggest a 3 number rating system. Here are some quick, nut-shell definitions:
O3 - Completely oriented: Obvious and conclusive evidence that the meteorite
stabilized during entire flight.
O2 - Partially Oriented: Evidence
Great Idea,
We have weathering grades and this should be just as simple.
Im currently busy w/ business at my desk but will add my thoughts regarding the
parameters of grading later today.
This seems long overdue to me.

Hello Mike and all,
Mike, I like your suggestion.
Obviously, a large contributing factor in a the final shape of a meteorite,
has to do with it's original shape of the rock before the fireball (or as it
broke apart in flight). Some rocks are just destined to look better (more

Steve List,
I just sent the following to Darryl off line, as we've been discussing this
issue with great interest, and thought I'd add it here because it
coincidentally makes very similar points (we very much agree) but with
perhaps a little different perspective:
Darryl,
Here are the
as previously mentioned, some of the guidelines used to establish
orientation should be weighted more heavily than others.
when a stone is weathered, the only way to determine a high degree of
orientation would still be the reliance on the same conventions to
determine the extent of
Darryl and All,
I think we all are frustrated when a rounded rocks (or even chunky not even
crusted fragments) are called oriented. It wastes time as we look for why
in the world it would be called oriented and it makes us wonder If they
will lie about that, what else are they lying about?
