Apparent magnitude

  1. May 2, 2006 #1
    The extinction to our galactic center is about Av=20mag. What would be the apparent magnitude of our sun at the 8000parsec distance of the galactic center?

    From what I know, I think I need to use http://en.wikipedia.org/wiki/Absolute_magnitude#Computation the luminosity-distance formula. So I'd have m=20mag+5*(log(8000)-1) . Is this correct, am I missing something, or am I going at this totally wrong?

    Close, but not quite. What would the sun's apparent magnitude be at that distance if there were no extinction?
