Conjunction occurs when the Sun and Moon are at the same ecliptic longitude (rotation angle measured in the plane of the solar system bodies). This means that they are close together in the sky, but not necessarily overlapping, since they may differ in latitude (the coordinate perpendicular to the ecliptic longitude). - JimMosher JimMosher

Additional Information

  • The moment of New Moon is defined as the moment when the Sun and Moon are in conjunction as seen by an imaginary observer at the Earth's center. - JimMosher JimMosher
  • See also: Saber's Beads, which is a curious optical phenomenon related to the very young (and extremely thin) moon's crescent (only a couple of hours after New Moon). Saber's Beads are also observable at the very OLD moon's crescent, a couple of hours before New Moon. - DannyCaes DannyCaes Feb 12, 2008
