Fireballs



 
If you see a fireball:

When a solid object enters the Earth's
atmosphere, it interacts with air molecules,
heats up to over 2000 degrees Fahrenheit,
and begins to glow.  The incandescent object
is called a meteor. 

Most meteors are produced by incoming
microscopic particles of dust left
behind by the passage of comets.
Occasionally, a larger object enters the
Earth's atmosphere, producing a very bright
meteor.  If the meteor is brighter than the
planet Venus, it is called a fireball. A bright
fireball will produce meteorites (which may or
may not be found).

 When there are a sufficient number of
eyewitness reports of a fireball, meteoriticists
can often determine the location where the
resulting meteorite(s) landed and meteorite
samples can be recovered.

If you see a fireball, please fill out the fireball
report form (click here for form) and mail it to
the Cascadia Meteorite Laboratory
(address on the form) or phone Dick Pugh
at (503) 287-6733.
