South Node

Meaning

The South Node is the point where the Moon’s orbit crosses the Sun’s path going south, always exactly opposite the North Node. The two move together, backwards through the zodiac, in a cycle of about 18.6 years, and an eclipse can happen only when a new or full Moon falls near one end of their axis or the other.

Modern astrologers read the South Node as what is already known: talents, habits and ways of coping that come without effort, sometimes felt as inherited or older than this life. They are real resources, and also a comfort zone; growth is usually described as carrying them towards the North Node’s end of the axis rather than leaving them behind.

Tradition called it the Dragon’s Tail and treated it as the North Node’s contrary, a point that diminishes or drains what it touches, of the nature of the malefics, Saturn and Mars. Many modern readers soften this into release: what the South Node touches is something to let go of lightly, or to give away.

In practice

• By house, the South Node shows where things come easily and old patterns repeat: in the 10th, being the dependable one at work comes naturally, while growth lies at the other end, in home and inner life.
• Planets close to the South Node are read as gifts brought in ready-made, which ask to be shared rather than leaned on.
• Transits over it are read as the return of familiar patterns, a chance to see what can now be released.

Across traditions

• Indian astrology counts it as Ketu, the headless body of the demon whose head is Rahu, the North Node; Ketu is linked there with detachment and spiritual release.
• Human Design reads the South Node as the setting of the first half of life, until about forty: the places and people that shape someone early.

Origin and history

The nodes have been followed since Babylonian eclipse reckoning, and Latin astrology named this end of the axis Cauda Draconis, the Dragon’s Tail. William Lilly, in 1647, gave it the nature of Saturn and Mars, the contrary of the Head. In 1975 Martin Schulman’s Karmic Astrology made the South Node the memory of past lives, a reading that much modern astrology has kept in gentler terms, as what someone brings with them.

How Ulune calculates it

Ulune places the South Node exactly opposite the true North Node from the Swiss Ephemeris, so the two share their speed and their motion, and no aspect is listed between them. Because any aspect to one node is also an aspect to the other at the same moment, the calendar follows the North Node alone: a transit to a birth chart’s South Node, such as a conjunction, is listed once, as the matching transit to its North Node, here an opposition.
