Apparent luminosities
Astrophysics
The brightness of an object as it appears from the earth. The apparent luminosity does not take into account the distance from the earth to the object; the sun appears as the brightest object in the sky but is really dimmer (has less intrinsic luminosity) than many stars. We tend to use this interchangably with Brightness, Observed Brightness, and Flux at Earth.
