Composite readings

Composite Sun to the Ascendant

A composite chart is built from the midpoints between two people's charts, so it is one chart for the pair rather than a chart for either person. These readings say what a placement in it stands for in a pair's shared chart.

Together

Composite Sun conjunct with the Ascendant
Who the pair is and how it comes across are one and the same, so its outward manner is a fairly direct picture of what it stands for.
Composite Sun in an easy aspect with the Ascendant
The pair's sense of purpose supports its outward manner, so showing who it is takes little effort and the two tend to reinforce each other.
Composite Sun in a hard aspect with the Ascendant
The pair's sense of purpose and its outward manner pull apart a little, so how it appears can differ from what it feels itself to be.

None of this is a verdict. A single placement never describes a whole relationship, and astrology is a tradition of interpretation rather than a body of established fact.
