FIREBALL UPDATE: 300 tons of TNT. That's the kinetic energy of the
meteoritic fireball sighted June 7th in Norway, according to Prof.
Peter Brown of the University of Western Ontario. Brown's doctoral
student, Wayne Edwards, arrived at this figure by analyzing
infrasound and seismic data. Early reports of a Hiroshima-like event
(12,000+ tons of TNT) were exaggerated.
"An object like this hits Earth about once a month," notes Bill Cooke
of the Marshall Space Flight Center. "The Norwegian event was similar
to the Park Forest meteorite impact of 2003."
The Norwegian meteorite probably did hit the ground. One candidate
landing site is viewed with skepticism by experts. The hunt
continues.
