Sun conjunct Moon in synastry is a fantastic aspect to have between 2 people because there’s a natural understanding between them. The Sun is sympathetic and responsive to the feelings of the Moon, often having an almost eerie ability to anticipate the Moon person’s needs. The Moon person can feel as though the Sun person can read their mind!
The Sun can represent our extroverted way of being – our basic persona and preferences. The Moon can be a little more introverted, or perhaps even shy about sharing what the Moon is all about. Some of us may wear our hearts on our sleeves, but generally we only share deep emotions with those we feel okay to be a little bit vulnerable with.
We can liken the Moon with Freud’s “Id”, the Sun with the Ego, and the Ascendant with the Super Ego.
The Id (or the Moon) is the part of us that dwells beneath the surface – it’s the instinctive reactions to our environment. The Super Ego (or Ascendant) is the lens through which we see the world – and in turn are seen BY the world. It is our conditioning based upon the family and society we find ourselves in. The Ego (or the Sun) mediates between the ID (Moon) and the Super-Ego (Ascendant) to form the basic personality.
The Sun operates in such a way that it moderates our primal, impulsive feelings so that they don’t get expressed as behaviors that are “inappropriate” to the culture, family, or situation we find ourselves in.
So — when the Sun and Moon meet in a conjunction in synastry – there’s an easy match. The INSTINCTS of the Moon person are expressed by the Sun person. The Moon person feels that the Sun is someone they can be comfortable with because there’s natural agreement between the 2 of them. The Sun person accepts the emotional expression and style of the Moon person – the Sun sees these reactions as being “appropriate”
When it comes to emotional expectations, expression, and behavior, those sharing the conjunction of Sun and Moon match up extraordinarily well. The two just GET each other. However — as great as this conjunction can be, it does have its drawbacks.
When a challenging transit comes along, both people will feel it — and may not have the strength or preparation to support each other. To give an example — let’s say that Saturn has come along and is sitting upon this conjunction. The Sun person becomes very ill and is given a grim diagnosis. The Moon person, meanwhile, becomes depressed, and in their depression, they are unable to give the Sun person the support and encouragement that is needed. The Sun person feels like a burden, and this does nothing to help facilitate healing! Saturn acting upon both of them at the same time “blocks” the ability of one partner to weather the storm of the other. They’re too busy dealing with their own storm!
