+The Local Meridian is an imaginary <link linkend="ai-greatcircle">Great Circle</link>
+on the <link linkend="ai-csphere">Celestial Sphere</link> that is perpendicular
+to the local <link linkend="ai-horizon">Horizon</link>.  It passes through the
+North point on the Horizon, through the <link linkend="ai-cpoles">Celestial
+Pole</link>, up to the <link linkend="ai-zenith">Zenith</link>, and through the
+South point on the Horizon.
+</para><para>
+Because it is fixed to the local Horizon, stars will appear to drift past
+the Local Meridian as the Earth spins.  You can use an object's <link
+linkend="equatorial">Right Ascension</link> and the <link
+linkend="ai-sidereal">Local Sidereal Time</link> to determine when it will
+cross your Local Meridian (see <link linkend="ai-hourangle">Hour Angle</link>).
