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.

photoelectric magnitude apparent magnitude The magnitude of an object as measured with a photoelectric photometer. (m_pe) (antiquated term)
