Sagittarius 24.3° · born December 17, 1902
Birth time unknown

Birth date sourced. Birth time unknown.Moon sign undetermined. The Moon crossed from Cancer into Leo during that day. Everything below uses only what the complete civil day settles.

The day, read honestly

Four of the nine placements whose signs are settled stand in Sagittarius — the Sun, Mercury, Venus and Uranus. The placements whose signs could change with an unknown hour are not counted. A cluster that size becomes the section the rest of the chart plays around.

Positions at 12:00 civil time in Cheonan—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.

Where the Sun actually stood

The Sun sits at 24.3° Sagittarius — the third decan, 20°–30°, which the tradition sub-rules by the Sun. Degrees matter more than the sign label here: two people born a fortnight apart share Sagittarius and share almost nothing else about where the Sun actually stood.

The personal registers

The personal planets sit Mercury at 26.9° Sagittarius, Venus at 28.6° Sagittarius, Mars at 28.6° Virgo. Mercury in a fire sign reads as a mind that decides at speaking speed; Venus in a fire sign reads as taste that runs toward the vivid and the immediate; Mars in a earth sign reads as drive that grinds rather than flares.

The angles that hold

Venus to Mars is the closest call of the day, a square within 0.0°. A square is the tradition’s engine room: two drives at cross purposes, and the friction is the horsepower. Behind it, Mercury square Mars at 1.8°, and Mercury conjunction Venus at 1.8° — both still well inside the orbs this site uses. Each angle here was measured at every hour of the civil day and held; whatever the missing clock said, this geometry was in it.

Figures in the geometry

The Sun opposes Neptune while both square Mars. The t-square is the figure the old texts trusted for output: friction with a fixed address. The Moon stands apart from every major angle the day held — the tradition reads an unaspected planet as a voice that speaks on its own schedule, unmodulated by the rest of the chart.

The classical map

Of the seven planets the classical scheme judges, two sit in a sign it has an opinion about. Mercury in Sagittarius at 26.9° is in detriment — the planet opposite its home, working against the grain; Saturn in Capricorn at 26.1° is in domicile — the planet in its own sign, running on home rules. The old table grades terrain, not talent — a placement in fall works uphill, nothing more.

The shape of the whole

The certain ground: 9 placements whose signs hold for the whole day, dividing 4 fire, 2 earth, 2 air, 1 water by element and 6 mutable, 2 cardinal, 1 fixed by mode. A fire emphasis is read as appetite for the first move, with information gathered by doing rather than before doing. Neptune and Pluto were retrograde — motion that reverses only from this vantage point, and which the old reading treats as delay used for revision.

The Moon is genuinely open

The Moon crossed from Cancer into Leo during that day at the birthplace, travelling 15.1° between one midnight and the next. A birth time would settle it in a second; there isn’t one. So the Moon stays unnamed here — the alternative is a guess wearing the clothes of a fact.
