Re: (meteorobs) Re: March 9th, 2000, Arkansas fireball
FYI Stuart, any time reports of glowing meteorites make the news or
have resurfaced from history (RE: the discussion about the 1885
meteorite that fell in Mexico, almost hitting a person and was reported as
glowing in the ground, it can be found on 18/02/99 06:14 Dav and on
18/02/99 08:05 Dav in the monthly meteorobs archives), they are
disregarded out-of-hand because they don't fit preconceived notions of desk
jockies who haven't ever seen a meteorite hit the ground and been there
within a minute or two. In heat treating iron and giving it a temper, the
trick is to allow the heat from parts not exposed to the cooling water or oil
(including thick, internal parts) to reheat the iron which can take a little
time depending on the thickness of the iron. The discussion in Feb. '99 was
almost all against glowing meteorites, but I can see where some meteorites
can have frost on them from the cold entry while others, particularly
larger iron meteorites, can glow from internal heat that reheated the
surfaces which may indeed cool off during the free flight. Few here agree
with me as evidenced by the Feb. '99 discussion.
