(meteorobs) An Explosion on the Moon

[Karl Antier]

Hi all meteor observers !

Just  a small question...
Quoted from the article :
"Suggs and Cooke next consulted star charts and lunar imaging software
and determined the meteoroid was likely a Taurid, part of an annual
meteor shower active at the time of the strike."
"The object that hit the moon was "probably a Taurid," says MSFC meteor
expert Bill Cooke. In other words, it was part of the same meteor shower
that peppered Earth with fireballs in late October and early November
2005."

So, I was just wondering : how do astronomers determine the shower of a meteor
crashing on the Moon by watching this brief sparkle ? Is it only made by checking
if the hit face of the Moon is in the direction of possible Taurids ? Or are there
other arguments that would favor such an hypothesis ?

Thanks in advance for your answers !
And clear skies to all !
