Read Aquarius through the planet
A sign describes a style of expression. The planet supplies the subject. A Sun reading concerns identity; a Moon reading concerns emotional needs and familiar responses.
Sun in Aquarius
Sun in Aquarius is associated with living by principles and questioning how a group works. You might care about changing an unfair rule even when it benefits you personally. A principle needs reconsidering when it overlooks the people affected by it.

An Aquarius Moon is associated with needing room to understand feelings before discussing them. Time alone after a disagreement can help separate a personal reaction from the wider issue. Explaining the situation logically still leaves the feeling itself to express.

The Ascendant describes the zodiac degree rising at the eastern horizon. In a reading, it concerns personal presence and the approach to unfamiliar situations. A birth time and location are needed to calculate it.
With Aquarius rising, Saturn is the traditional chart ruler. Its sign and house connect the rising-sign interpretation with another part of the chart.
Modern astrology also associates Aquarius with Uranus. Astriel uses Saturn in its traditional ruler calculations.

The same sign, different questions
An Aquarius Sun concerns the principles a person chooses to represent. An Aquarius Moon concerns the emotional conditions of participation. Someone can advocate a shared goal while needing a direct, personal check-in when upset. Agreement about an idea does not replace attention to a relationship.
These are illustrative interpretations, not facts inferred about you.

Find the rest of the context
A sign label is one part of a placement. Read it alongside the planet, house and aspects. These describe different chart relationships.
The degree range, with an example
A longitude of 315° is 15° Aquarius. At exactly 330°, the next sign, Pisces, begins.
Every tropical sign spans 30°. The signs are equal coordinate divisions; the astronomical constellations have different boundaries.
Read the calculation methodsPlacidus houses with Aquarius rising
The Ascendant degree in Aquarius starts the 1st Placidus house. Its end and the remaining cusps depend on the exact birth time and location.
Read the calculated house list rather than counting one sign per house. A sign can appear on consecutive cusps or sit inside a house without starting one.

Gemini and Libra share the air element. Leo is opposite Aquarius in zodiac order.
Matching degrees in opposite signs are 180° apart. Exact degrees and the permitted orb decide whether two placements form an aspect.
Sign categories do not provide a relationship score. A two-person comparison needs the placements in both charts.
Understand aspects and orbs · Compare two chartsWhen a birth time or sign boundary is uncertain
Calendar date lists are approximate. Near a Sun-sign boundary, the year and birth time can change the answer. If an uncertain birth period includes a sign change, Astriel shows the alternatives.
Unknown birth time leaves the Ascendant and houses unavailable. The available planetary signs remain in the result.
