Liking the website, I always enjoy the histories and stories that historic
meteorites have to offer to the meteorite collection community. These historic
falls help mold and guide meteorites collecting and science the way it is
today. Enjoy to see more from this website and other
Hi List,
It seems like there have been many fireball sightings in the past few
months but no material being found on the ground, as in the recent
Oklahoma event. I was wondering if the absence of a sonic boom has
anything to do with it.
Does a sonic boom or explosion have to be present for a
The actual term commonly found in the scientific literature is potted
butt. It refers to a small specimen embedded in some kind of supporting
medium, usually epoxy, acrylic, or the like, prior to sample processing.
These samples then may be sliced for thin section preparation or other
purposes,

Of course, there is a continuum of meteorite sizes down through
micrometeorites to dust, all of which have been collected on Earth. The
smallest named meteorite found on Earth may be Yamato 8333, at 10 mg. There
are perhaps a dozen more, all Antarctic, below 100 mg.

Curious... I know there are many variables involved, and it probably
varies with the conditions under which each event occurs, but I've read
that some people have heard sonic booms (as low boom/rumbles) up to 50
miles away or more.
Couldn't one figure out that distance by calculating altitude

All,
There are several falls where no sonic boom was noticed. Speaking of US falls,
the last two that come to mind are Berthoud, CO and New Orleans, LA. Others

two specifically state there were no explosions or

Hi All,
I had a chance to talk to Skip Wilson about the Portales Fall. The

apart.

Hello Sonny and Listmembers,
Interesting. Perhaps the sound waves travel around the epicenter (anything
located directly beneath) as they move towards the ground. I imagine circular
rings moving expanding in an outward direction as they travel to the Earths
surface. The higher the altitude of
Something to consider... If all events with sonic booms generate meteorites,
then there are meteorites on the ground in Louisiana/Mississippi from the big
fireball there a couple of months back. Here's Jake Schaefer's page on that
