Declination
... The sign is customarily included even if it is positive. Any unit of angle can be used for declination, but it is often expressed in degrees, minutes, and seconds of arc. A celestial object that passes over zenith has a declination equal to the observer's latitude. A pole star therefore has the decl ...
