In astronomy, a vertical circle is a great circle on the celestial sphere that is perpendicular to the horizon.  Therefore, it passes through the zenith and the nadir.  There is a vertical circle for any given azimuth, where azimuth is the angle measured east from the north on the celestial horizon.  The vertical circle which is on the east-west direction is called the prime vertical.  The vertical circle which is on the north-south direction is called the Local Celestial Meridian (LCM) or Principal Vertical.  Vertical circles are part of the horizontal coordinate system.
