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. For comparison, "the Norwegian event was similar
to, but somewhat less energetic than the Park Forest meteorite impact of 2003."

Meteorites from the Norwegian fireball are probably lying on the ground--but
where? One candidate landing site is viewed with skepticism by experts. The hunt
continues.
