A question of magnitude...

Hi Guys

Just a question about the apparent visible magnitude of the Sun and the Moon. By using the absolute bolometric magnitude for the Sun of +4.77 (at 10 psc) I get an apparent magnitude of -26.8 at 1 A.U. So what then is the visible magnitude for the Sun?

And by using an albedo of 0.06 for the Moon, it's apparent bolometric magnitude is -11.3. What are the currently accepted values for these figures?

PS Ever wonder how far from the Sun you have to be for Sunlight to be as weak as Moonlight? That's my question.
