(meteorobs) About magnitudes
Hi,
I'm little lost with magnitudes. Since the magnitude of a full
moon is -12.5, does this number represent the light coming from the
whole moon's disk (not just moon's surface brightness)?
So, if a fireball, more or less a point source, is rated as
magnitude -12.5, does it light the ground as brightly as a full
moon?
