The relation of geocentric to apparent co-ordinates depends upon the latitude of the observer.
The choice made by Hipparchus of the geocentric theory of the universe decided the future of Greek astronomy.
But the explanation of this phenomenon is equally consistent with the geocentric as with the heliocentric theory of the solar system.
But the observations do not extend continuously throughout the year, and do not include a sufficient length of the central line on each evening to enable us to distinguish certainly the heliocentric latitude of the central line, as distinct from its apparent geocentric position.
The geocentric latitude of a place is the angle which the line from the earth's centre to the place makes with the plane of the equator.
