apparent magnitude magnitude Measure of the observed brightness of a celestial object as seen from the Earth. It is a function of the star's intrinsic brightness, its distance from the observer, and the amount of absorption by interstellar matter between the star and the observer. The m_v, of Sun, -26.5 mag. A sixth-magnitude star is just barely visible to the naked eye.

photographic magnitude apparent magnitude The magnitude of an object as measured on the traditional photographic emulsions, which are sensitive to a slightly bluer region of the spectrum than is the human eye. (m_ph)(antiquated term)
