Apparent Magnitude

Apparent magnitude - The apparent magnitude (m) of a star, planet or other heavenly body is a measure of its apparent brightness. The brighter the object appears the lower its value.
Absolute magnitude - In astronomy, absolute magnitude is the apparent magnitude, m, an object would have if it were at a standard luminosity distance away from us. It allows the overall brightnesses of objects to be compared without regard to distance.
Limiting magnitude - Limiting magnitude is the faintest apparent magnitude detectable or detected by a given instrument.
Photographic magnitude - Before the advent of photometers which accurately measure the brightness of astronomical objects, the apparent magnitude of an object was obtained by taking a picture of it with a camera. These images, made on photoemulsive film, were more sensitive to the blue end of the visual spectrum than the human eye or modern photometers.
