The Sun in Leo is in domicile, the planet's own home, and the tradition lists no other planet's rulership here. Leo is a masculine, fixed fire sign; the Sun is a masculine, day-team planet, so sect, gender and sign agree.
Leo is the fifth sign of the zodiac, a fixed fire sign with positive polarity, and the only sign the Sun governs in traditional astrology.

The Moon in Leo is in the Sun's home sign, a masculine, fixed fire sign. The tradition lists no domicile, exaltation, detriment or fall for the Moon there.
Leo is a fixed fire sign with positive polarity, the sign the Sun governs, and a Moon there sits in the Sun's home. Modern psychological astrology reads the emotional need here as warmth returned: to be noticed, appreciated and welcomed.

Leo rising places Leo on the eastern horizon at birth, and because the Ascendant changes sign about every two hours, a birth time is required. Under whole-sign houses, where each sign is one house, Leo is the first house. The Sun, the planet that rules Leo, is the lord of the Ascendant. The Sun rules only Leo, so there is no second sign for it to rule elsewhere in the chart. It is exalted in Aries, your ninth house. Leo is a masculine, fixed fire sign and the Sun's own home. Sect, the tradition's sorting of planets into day and night teams, puts the Sun on the day team. Hellenistic astrologers therefore ask whether the chart was born by day, when the lord of the Ascendant is above the horizon and in sect. The Sun's sign and house are among the first facts read.

Reviewer's notes
Dignities, houses counts, genders and modalities matched the project's own dignity tables and Ptolemy/Valens. Lord-of-the-Ascendant importance confirmed only in secondary sources (Astrology Podcast); softened 'first/main' to 'among the first/key'.

A Leo Ascendant records Leo rising in the east at the moment of birth. The rising sign changes about every two hours, so it depends on birth time and place. Modern psychological astrology reads the Ascendant as a manner of entering situations. For Leo, a fixed fire sign, authors describe a warm, visible and self-assured approach, with a first impression of presence and generosity. The tension they name is performance: a habit of appearing confident whatever the underlying feeling. Hellenistic astrologers read a Leo Ascendant by the Sun as its lord. They weigh whether the chart is diurnal (born by day) or nocturnal (born by night), a distinction called sect that shapes how the Sun is judged. Modern authors place less emphasis on sect.
