    What the hell is a Johnson V Magnitude????

    Is the Johnson V Magnitude the same as the Apparent Magnitude??? I don't think it is. Are they related???

    Johnson V magnitude is measured using a filter that 'clips' light frequencies save those in in the human visual range [hence the 'V' designation]. They are widely used in photometric studies.
